Abstract
Building Information Model (BIM) is now a well-established notion in the context of built
environment management, which includes the construction industry and the facility
management industry. At first sight, BIM represents the various tools that support formulation
and usage of models of built environments. Vendors that develop and provide BIM technologies
typically offer bold promises regarding the positive effects of the usage of BIM. These positive
effects include increased efficiency, quality and safety, in the context of the whole lifecycle of a
built environment. However, the main emphasis of that rhetoric is placed on the benefits gained
from using BIM in the construction and maintenance of new built environments. As the
overwhelming majority of built environments are made up of already existing constructions,
rather than projected buildings, a key question is: what are the practices for the use of BIM for
existing buildings? An explorative research study has been conducted to respond to that
question. The main research methods employed included a comprehensive literature review
and interviews with BIM experts. The key findings suggested here are: (a) that very little
research addresses the actual practices of BIM usage for existing built environments, (b) BIM as
such represents a rather complex, multi-dimensional phenomenon, that also introduces new
complexities into the lifecycle of built environments, (c) BIM has many stakeholders of which
some have conflicting relations with each other; (d) there is a need to conduct comprehensive
and independent research into the domain of the use of BIM for existing built environments.

Foreword
In May 2013, a chance meeting took place between two of the authors of this text. One
(Magnusson) had just completed his professorial installation lecture while the other (Haftor) was
about to start his professorial installation lecture in the same lecture room. The first lecture was
about Building Information Models and Modeling (BIM) while the second was about Information
Logistics. When passing each other in the doorway, we exchanged brief greetings and
remarked that we may have some common interest. Several weeks later, the two of us met and
discussed BIM, which made us realize that our respective fields have a number of areas in
common and that it would be interesting to explore them. We subsequently brought in two
additional colleagues and thus established a multi-disciplinary team, with regard to buildings,
their maintenance and conservation, and the information and information systems that support
these activities. When the four of us met and discussed, we ended up wondering about the
current practices and research with regard to the use of BIM for existing built environments.
Consequently, we decided to run a part-time explorative research project, with the aim of
answering that question. Given that we had limited resources available our method was limited
to the review of literature and some interviews with experts in the field, in Sweden. In practice,
one of us (Johansson) conducted the majority of the actual research, while the other three of us
acted as supporters. We held several progress meetings to discuss our findings. When the
study had been completed, we were somewhat surprised by the answers obtained, namely that
there is no informed answer available as to the current practices and research with regard to the
use of BIM for existing built environments. The reason for this is that very little empirical study
has assumed that focus. The remarkable thing with this answer is that the BIM concept and its
associated technologies are not especially new, and that its promoters and various technology
vendors have put forward bold statements about the positive benefits from BIM. However, as far
as our study could find, no research has been conducted that can tell us whether these
statements are realized and sensible or not. However, this study has succeeded in identifying a
number of details and inherent complexities about BIM and its use. One conclusion is that BIM
could be regarded as a kind of neural system for any activities related to build environments,
and in such a way transforms our understandings and practices within such an environment to
the better. With this perspective, we are happy to invite the reader to peruse the following text.

1. INTRODUCTION
Information and communication technologies virtually dominate every part of our lives: private,
professional, and civic. This seems to be true for the various manufacturing industries, such as
the automotive or construction industries. Just as an engineer may produce a digital model of a
car, where such a model may at a later stage guide the manufacturing, usage, and also
recycling of that car; professionals construct models of built environments, to guide the
planning, construction, usage and maintenance, and eventually recycling, of a building. The
formulation and handling of these models is often associated with the label of “Building
Information Models”, or simply “BIM”. Briefly, BIM may be regarded as professional tools for the
creation and usage of models of built environments. The introduction of BIM technologies by
various vendors is often associated with bold promises about the positive effects on the quality
and efficiency of the various activities that constitute the lifecycle of a built environment. Most of
that rhetoric, however, seems to address the use of BIM for the building of new constructions,
rather than for existing built environments. A relevant question that emerges is: what are the
practices of the usage of BIM for existing built environments? An attempt to answer that
question triggered the explorative research project described here.
Rather surprisingly, the study’s findings suggest that little, if any, research has been conducted
with focus on the usage of BIM for existing buildings in Sweden. The results suggest that BIM
technologies offer many bold promises about the positive outcomes from its usage, yet little is
known of whether these effects are realized or not. Further, BIM seems to be a rather complex
phenomenon that also introduces additional complexities into the lifecycle of built environments,
which also acts as a hinder for the adoption of BIM technologies, for built environment. This in
turn seems to require multi-disciplinary approaches from both BIM professionals and its
academics.
This text is organized as follows. The next section explicates the assumed Research objective
and its purpose while the section after that summarizes the research approach employed. The
findings produced by the study are presented in two principal sections, first Current BIM

Practices and then Proposed Research Frontiers. A section with Conclusions ends this text
together with references and details of the research team.
2. PURPOSE AND OBJECTIVE
Figure 1. Illustrates the assumed focus of the study reported in this text;
the use of Building Information Models (BIM) for existing Buildings.
This report presents the outcome of a finalized explorative research study into the use of
Building Information Models and Modeling (BIM), for existing rather than projected buildings,
with particular focus on Sweden (see Figure 1). While the project had several desired
outcomes, one central objective guided the formulation this report:
To have identified frontiers, in both research and practices,
with regard to the use of BIM technologies for existing buildings,
with special focus on Sweden.

More specifically, this implied a search for key features of current BIM practices, their
successes, limitations, challenges and opportunities. Likewise, it implied a search for finalized
research initiatives focused on BIM practices, and provided us with insights about their key
characteristics, strengths and limitations. The main emphasis of this study, though, was to
establish what we do know about BIM practices, and what their challenges are.
Several key factors motivate such an assumed focus of this exploration. Firstly, and in more
general terms, promoters of BIM and its practices as a new technology have often presented
BIM as a glorifying technology that will provide many benefits. The question is whether any of
these benefits from using BIM have been realized or not, and what the associated challenges
and opportunities are. Secondly, BIM ambassadors seem to have assumed a main focus on
BIM use for the design and construction of new buildings. Both these assumptions are evident
in available literature, and in numerous sources online (see bibliography). While such a focus
has its merits, we need only to recall that the majority of the building stock (70 – 80 %) in
western societies was built before the 1970s and is thus considered as existing buildings
(OECD/IEA, 2009).
Therefore, ignoring the question of how to use BIM for existing buildings implies a radical
reduction of the aspired potential effect of using BIM. Thirdly, there is an ongoing discourse
regarding the actual process of the development of BIM technologies and associated practices
(see the chapter on research), which is important. However, there also is a need for solid
knowledge regarding the use of BIM itself, as such knowledge may potentially inform future
BIM development practices with regard to the kind of BIM desired, or not.
Given the research objective as specified above, the research purpose assumed here is that
the outcome of the study is:
Use of BIM for existing Buildings
9
To serve as an intellectual guide for the formulation of a future research direction (e.g.
program, initiative, projects), that addresses the use of BIM technologies for existing
buildings, in Sweden.
Beside the key objective as declared above and the purpose of this study, several other
objectives were aspired to, of which at least one deserves a mention, namely: to have
established a well-coordinated cross-disciplinary research team, for subsequent research work.
However, these “other objectives” lie outside the scope of this text.
3. METHODOLOGY
The research approach assumed here for achieving the objective specified above may be
summarized in the following terms:
a. Literature Review: a careful search and review of existing literature, both academic and
professional; this comprised a search, identification and retrieval of literature followed
by reading, analysis and pattern recognition.
b. Expert Interrogation: identification of key experts within the assumed domain, interview
and discussion related to the focus assumed here.
c. Multi-disciplinary Team: a crucial component was to put together a research team with
members representing various disciplines related to the focus assumed here.
d. Driving Research Questions: given the objective detailed above, a set of driving
questions were formulated, as a means to translate the assumed objective into
Use of BIM for existing Buildings
10
operational questions as instruments for data collection. Example of such central
questions include:
o The What:
What is “BIM”? What does it stand for and for whom?
What are the constituting components and functions of BIM?
o The Why?
What are the key motivations for the development and deployment of
BIM?
What are the key needs with which BIM is assumed to deal?
What are the key opportunities that BIM is assumed to explore?
Who are the key stakeholders (actors) involved in BIM?
What are the key stakes or interests for each BIM stakeholder?
o Actual?
How is BIM actually used?
What key problems, limitations and challenges arise from BIM usage?
And what are the reasons for these?
What is the difference, if any, between the actual use of BIM versus the
aspired ambitions, and driving motivations, for BIM use?
To what extent is BIM used for existing buildings?
What are the key hinders for successful BIM usage?
What are the key factors for successful BIM usage?
o Future?
What future development of BIM technologies and associated practices
is likely to materialize and how may that influence the use of BIM for
existing buildings?
What new knowledge is needed about BIM usage for existing buildings?
e. Reference Framework: the explorative study reported here was also guided by a
conceptual body, with a set of assumptions and standpoints which may serve as a point
of perspective or as a point of departure for the research work conducted. Indeed, any
Use of BIM for existing Buildings
11
research study, particularly one of explorative character like this one, has a Reference
Framework, as understood here, however this is usually implicit, not articulated and
reflected upon. The Reference Framework assumed here may be summarized as
follows:
o This investigation is based on the so-called ‘holistic paradigm’, in the present
context manifested in terms of (1) Sustainable Building, and (2) Sustainable
Integrated Conservation (SIC) that combines humanistic and sustainability
values and systems thinking, all applicable to BIM as a means for dealing with
cultural heritage, and the natural and built environment at large. This is intended
to improve the quality of life by protecting human health and encouraging
sustainable management of natural, human and man-made resources. The
focus is on continuous adaptability of the built environment, and on enhancing
its quality and diversity at all levels (Fielden,1982).
o Key activities of Sustainable Integrated Conservation include monitoring,
assessment, preservation, rehabilitation, adaptation, maintenance, and
management of built heritage and related assets, often in conjunction
with urban planning and design;
with environmental, social and material aspects;
with new construction technology and design;
with legislative issues;
with entrepreneurship, business, innovation; economy;
with humanities, arts and crafts, and
with education, training and research.
o An explicit recognition and assumption of participatory and preventative
practices, collaboration and synergetic learning is made here, with the potential
of anchoring the community’s intangible inheritance (e.g. Gustafsson & Rosvall,
2008; Horwitz & Aravot, 2008).
o Sustainable building includes all aspects of building performance,
environmental, economic and social impacts. This requires integration of various
kinds of knowledge and expertise in the inter-related fields of building
Use of BIM for existing Buildings
12
technology, conservation, environmental science, design and crafts, informatics,
business, natural and social sciences, economy, business and health etc.,
where different models can help promote the sustainability of
anticipated/planned activities, their impact and effects. The intention is to
eliminate negative environmental impact through skillful, sensitive design, and to
improve the efficiency of rapidly increasing impacts. From the perspective of
existing resources, sustainable building means ensuring the continuing
contribution of heritage to present and future generations through the dynamic
management of change responsive to the historic environment (Johansson,
2012; Fielden,1982).
o Architectural conservation and transformation in this context include
preservation, renovation, rehabilitation and reuse of everything from individual
buildings and objects to landscapes and streetscapes and urban revitalization of
mass housing (Engelbrektsson & Rosvall, 2013).
4. CURRENT BIM PRACTICES
It is now time to provide a summary of the current BIM practices, as identified in this study.
Recalling that the assumed focus is on BIM usage for existing buildings in Sweden, a more
definitional elaboration will be provided to address the question of what is meant with the notion
of BIM. This elaboration will then move its attention to why BIM is established; however when
we answer the-what of BIM and the-why of BIM, the question of the-how of BIM will inevitably
appear.
4.1 THIS IS BUILDING INFORMATION MODEL-ING (BIM)
In very basic terms, BIM may be regarded as a computer based database containing various
models of buildings. In this context, the expression ‘models of buildings’ refers to some kind of
representation of some part of a building, where that building-part is represented in terms of
Use of BIM for existing Buildings
13
selected attributes. Such a base of information about buildings is synonymous to a base of
information about a machine, say a car, that is designed and then manufactured, or a customer
database in a firm’s marketing function, where information about the customer is stored for
various purposes.
BIM, being based on the use of Information and Communication Technologies, is able to
conduct the basic information processing functions: to generate, store, transfer and transform
information. The notion of ‘Building Information Model’, or just ‘BIM’, emerged in the 1970's and
originates from semantic data models in the field of machine engineering. These models were
originally designed for connecting logical and physical information about machines, and
subsequently spread from the design and construction of machines into the design and
construction of buildings (e.g. Wikipedia.org).
The first implementation of BIM was as a part of the Virtual Building concept and debut of
ArchiCAD in 1987 (ibid). These concepts and applications were adapted, developed and
modularized during the 1980's, enabling transferability of the technology and systems to the
residential and commercial sectors. One example of early BIM-related models and
development is the ‘Building Design System’, which was generated through a research project
funded by the UK government in the mid-1970’s. Another example is ‘Really Universal
Computer Aided Production System’ (RUCAPS), a computer aided design that was developed
by John Davison and John Watts from the University of Liverpool (ibid).
Generally speaking, key constituting parts of a Building Information Model include (1) an object
(a part of a building, a building, or group of buildings typically represented in 3 dimensions); (2)
parametric interconnected data related to (1); and (3) meta-data (data about data, here
definitions and specifications of (1) and (2), (see Figure 3; Magnusson 2013). In the context of
this report, BIM may be understood as:
Use of BIM for existing Buildings
14
1. A set of technologies, processes and policies enabling multiple stakeholders to
collaboratively design, construct and operate a facility, or group of facilities, and to
sustainably manage them in the context of their environment (Succar, 2013).
2. A rich information model, potentially fed by multiple data sources, elements of which
can be shared across all stakeholders and maintained throughout the life of a building
from inception to recycling (Waterhouse, 2013).
3. A shared digital representation of physical and functional characteristics of any built
object, and its environment, which forms a reliable basis for decisions (ISO/TC 59/SC
13).
In general, three major kinds of information are included in any given BIM: (a) Geometric, (b)
Semantic, and (c) Topological information (Schlueter & Thesseling, 2009). Geometric
information relates directly to the built form in three dimensions, semantic information describes
the properties of components, while topological information captures the dependencies of
components.
BIM is characterized by work-practices that employ digital models of buildings. The initial
guiding idea was to develop a virtual building model to guide the building process; as the
physical building is assembled, changes in the field are documented in the virtual model. An
essential ingredient in BIM is that the object carries metadata. By using three to five
dimensional digitization models, distinct phases of design are merged and the process
becomes fluid, or well integrated, with an aspiration for an elimination of information loss
between the activities constituting the work practice. BIM models consist of objects (i.e.
representations of buildings and building elements such as walls, windows, columns, etc.), but
also various types of information items, such as areas for specific rooms, zones, tenants, etc.
This differs from traditional 3 Dimensional Computer Aided Design (3D CAD) which focuses
only on the 3D graphical representation of a building. Current BIM technologies may provide
Use of BIM for existing Buildings
15
the design and geometry of a building; geographic information, light analysis, spatial
relationships and characteristics of building materials (Magnusson, 2013) – see Figure 3 for an
illustration.
The term ‘Building Information Model’, as such, first appeared in 1992 (van Nederveen &
Tolman 1992). However, the terms ‘Building Information Model’ and ‘Building Information
Modeling’ (BIM) began to be used more extensively from 2003 onwards (Autodesk, 2003).
Nowadays, BIM represents a whole new paradigm, representing a turn away, or advancement,
from the traditional practices of design and construction of buildings. It is not only considered
as a way to make a profound impact on the professions, but is also regarded as an approach to
assist the building industry in the development of new ways of thinking and practices. BIM may
be considered as a ‘socio-technical system’, combining man-made technology and the social
and institutional practices that develop and use that technology. In such a view, BIM is
sometimes regarded as a unified system, or entity, consisting of different interacting aspects
that are material, mental, and social (see Figure 2). The social aspects include different types
of behavior, norms, cultural institutions and relationships. Indeed, these social aspects both
utilize BIM hardware and are shaped by it (WSP Group, 2013: retrieved
http://buildinginformationmanagement.wordpress.com, 2013-12-27).
More recently, the term BIM is used both as a verb and as a noun, that is Building-Information-
Model and as Building-Information-Modeling. The latter recognizes that the practice of the
formulation and usage of such models are highly interrelated. So, BIM accounts for the various
human practices (i.e. activities, processes, norms and values) that ‘formulate building
information models’ (Eastman, C., P. Teicholz, et al., 2011, p. Xi). Therefore, BIM requires a
notion as a combination of technology and a set of work processes (WSP Group, 2013, pp. 6-
7).

Figure 2. Illustrates one particular notion of BIM as a socio-technical system,
constituted of various hardware and software, as well as mental and social
aspects; Retrieved WSP Group, 2013: retrieved from:
http://buildinginformationmanagement.wordpress.com, 2013-12-27.)
While the construction, maintenance and usage of models of buildings is almost as long as
human writings, it is the digitalized building information models that offer such unparalleled
opportunities to produce, store, share, and transform building information models, which again
highlights the importance of the BIM practices. In these practices, an early ambition is that
different actors share data through digital models in a coordinated, consistent workflow, during
the building process as a whole, according to an integrated lifecycle (LC) perspective
(Garagnani, 2013).
Another early ambition of digitalized BIM may be summarized in terms of the three C’s: (1)
Collating Information, (2) Incorporating Consistency, and (3) fostering Collaboration and
Coordination among different actors and professionals. An ambition with these three C:s in
place is that building information and the process of building information can be managed
intelligently rather than in an ad hoc manner, arbitrarily and accidentally.

revolution/); retrieved 2014-02-21).
As the design, construction, maintenance, use and then termination and recycling of any non-
trivial building includes the generation of a significant volume of necessary information about
the given building, BIM may be regarded as the neural system for building-related practices. In
that sense, “BIM is a disruptive technology, which means it requires the change of practices.
Thus, BIM is socio-cognitive: breaking the syntactic, semantic and pragmatic barriers between
disciplines. This change is multi-dimensional and requires breaking the boundaries between
research disciplines.” (ibid)
’Computer Integrated Construction’ (CIC) can be defined as “the integration of corporate
strategy, management, computer systems, and information technology throughout the project’s
entire lifecycle and across different business functions” (Wikipedia.org). CIC and BIM are the
most often used acronyms that represent the use of information and communication
technologies in construction, however, CIC will be disregarded here as it has not been shown
to have any significance for the research focus assumed here (Wong & Yang, 2010).
Finally, the ‘Industry Foundation Classes’ (IFC) data model is intended to account formally for
building and construction industry data. It is a platform-neutral, open-file format specification
that is not controlled by a single vendor or group of vendors. It is an object-based file format
with a data model developed by buildingSMART (formerly the International Alliance for
Interoperability, (IAI) to facilitate interoperability in the AEC industry, and is a commonly used
collaboration format in Building Information Modeling based projects. The IFC model
specification is now an official international standard (ISO 16739:2013). Because of its focus on
ease of interoperability between software platforms, the Danish government has made the use
of IFC format(s) compulsory for publicly aided building projects. The Finnish state-owned
company Senate Properties demands that IFC compatible software and BIM be used in all their
projects (Wikipedia.org)

(CAD) that enable the formulation, storage and use of Building Information Models, that in
turn enable a more intelligent, or sophisticated, work practice where buildings and their
representations are key features. (Source: Wong & Yang, 2010, p.3).
4.2. SOME BENEFITS ASPIRED FROM BIM USAGE AND PRACTICES
As is rather common in most newly emerged technologies, many aspirations and promises are
made and assumed with regard to the potential benefits of the usage of new technologies; this
is also the case with BIM. An account of the various BIM benefits offered to professionals is
summarized below. This should not be regarded as a perfect and finalized list of potential
benefits however; rather it is an account of the commonly presented BIM benefits.
Use of BIM for existing Buildings
19
Information sharing & integrity: For the professionals involved, BIM enables the simultaneous
handling of information by different individuals in different professions. A purpose is to reduce
the information losses that may occur when a new team takes 'ownership' of a project and/or
building. Enabled by contemporary Information and communication technologies, BIM ensures
that one official version of information of a building is held consistently over time. (Magnusson,
2012)
Integrated Project Delivery: BIM enables an entirely new way of designing and building, known
as integrated practice, or ‘Integrated Project Delivery’ (IPD). This includes not only design and
construction professionals and preservationists but also cost estimators and vendors, energy
and code officials, and external reviewers. The practical use of BIM goes beyond the initial
building planning and design phase, as it extends throughout the building’s lifecycle and
supporting processes including cost management, construction management, project
management, facility maintenance and operation (see,
http://www.helsinki.fi/cradle/news_archive/index.htm; retrieved 2014-01-22).
Lean construction: Lean construction is an industrial and managerial practice stemming from
the popular lean manufacturing as originally developed by Japanese car manufacturing
companies. At its core is that the only performance and resource activities utilized should be
those that truly generate value for the output’s consumer, say a car buyer. To that end, a lean
approach recognizes that there is a constant need for improvement, in order to identify a leaner
way of conducting operations: in other words to increase the satisfaction of consumers and
reduce resource utilization, or more concisely, to do the right thing in the right way, only. Lean
extends from the objectives of a lean production system – maximize value and minimize waste
– to specific methods and technologies. As a result, the process is designed to better reveal
and support customer purposes. Work is structured to maximize value and to reduce waste.
Efforts to manage and improve performance are aimed at improving total project performance,
since this is more important than reducing the cost or increasing the speed of any particular
activity. Lean challenges the belief that there must be trade-offs between time, cost, and
quality. As the bringing about continuous improvement, in terms of what is done and how it is
Use of BIM for existing Buildings
20
done, requires extensive and accurate information about what is done and how it is done, BIM
becomes something of a neural system of any building lifecycle, and may help make the
building lean practice even more successful. (www.leanconstruction.org)
Safety: BIM places the effective use and exchange of information at its heart. Such information
use may be preventative in that it aids in collision detection at the initial planning stage,
identifying the exact location of discrepancies. This could lead to a more coherent safety and
vulnerability representation and proactive risk assessment of cultural heritage, facility contents,
qualities and potential threats, e.g. supporting the identification of vulnerabilities in building
emergencies (Kapp, 2012).
Computer-aided facilities management (CAFM) refers to the use of information and
communication technologies to effectively manage physical facilities in various ways. This can
include long-range facilities management reporting, as well as more direct systems that actively
manage aspects of facilities, such as lighting or heating and air conditioning equipment.
Common features of computer-aided FM tools include systems that give information on floor
plans and descriptions of physical space, as well as reporting on energy consumption.
Computer-aided facilities management tools can use extensive databases and visual modeling
tools, along with geographic information systems or services, to give project leaders and
managers a bird’s eye view of a particular facility or building. In addition to providing these sorts
of physical tools, computer aided facilities management systems can be part of long-term
planning and auditing resources. For example, planners might use these sorts of tools to
evaluate the depreciation of a facility or for other tax purposes. A wide range of CAFM-solutions
has become extremely valuable to those who are tasked with efficiently managing the physical
locations of a business or other entity. (www.techopedia.com, 05-02-14). Clearly, while
information and communication technologies in general manifest a significant potential for an
improvement of facility management, BIM may be regarded as a central component of such
technology usage (Magnusson, 2012).
Facility management: is a profession that encompasses multiple disciplines to ensure
functionality of the built environment by integrating people, place, process and technology into a
Use of BIM for existing Buildings
21
coherent whole. The core competencies of Facility Management may include: Operations and
Maintenance, Project Management and Quality, Real Estate and Property Management,
Technology and Communication; Readiness for Emergency and Business Continuity;
Environmental Management and Sustainability, Finance and Business, Human Factors,
Leadership and Strategy (International Facilities Management Association, 2014). Clearly,
successful management of any non-trivial building, such as an airport or a large hospital,
requires a timely supply of a significant amount of accurate information (Haftor & Mirijamdotter,
2011), at the hands of various professionals. In this sense, well-established BIM practices have
the potential to improve Facility Management immensely, in in a multitude of ways (Magnusson,
2012).
Intelligent Buildings: The expression ‘Intelligent buildings/homes’ encompasses a variety of
technologies, spanning commercial, industrial, institutional, and domestic buildings, for
example ‘Building Energy Management Systems’ (BEMS) and building controls. The notion of a
smart building or home was born in the late 1970s, and refers in very general terms to
structure and functions, systems and services, building and relationships for various ends, yet
in general for an increased efficiency, performance and comfort manifested by buildings and
homes. It is based upon the extensive application of various information and communication
technologies that enable networked monitoring, control, and communication within and
between buildings, of various parameters of the building and home. These technologies may
include broadband, television, telephones, fire alarms, energy management, lighting control, air
conditioning and access control, which allows buildings to be controlled intelligently (American
Intelligent Building Institute, 2012; Greentech Advocates, 2013).
4.3. BIM IN THE INDUSTRY
The various BIM functions and promises for practitioners are outlined and their needs are
highlighted in the text below. As mentioned earlier, the function of BIM is mainly focused on the
production of new buildings while very little attention and effort are put into BIM initiatives for
existing buildings.
Use of BIM for existing Buildings
22
BIM prevents errors by enabling conflict or 'clash detection' whereby the computer model
provides visual highlights to the team showing where parts of the building (e.g. structural
frames and building services, pipes or ducts etc.) may wrongly intersect. In the near future, this
might include information about which parts are original to the building, and which parts have
been added over time, making it easier to make proper judgments and decisions. For existing
buildings and environments, additional issues may be relevant, such as documentation of
structure and materials, geometric data for specific elements, such as details, floorboard and
trim, etc. Dynamic information about the building, such as existing conditions, sensor
measurements (e.g. moisture detection and energy efficiency) and control signals etc. can be
incorporated within a BIM model to support analysis of building operation and maintenance,
which in turn may serve as a basis for decisions, e.g. about rehabilitation/adaptation and reuse
(Kapp, 2009).
Professionals, manufacturers and sub-contractors from every trade may input crucial
information into a BIM before beginning construction, with opportunities to pre-fabricate or pre-
assemble some systems off-site, make final adjustments and make a cost-effective
rehabilitation and preservation and maintenance plan. Waste can be minimized on-site and
products delivered on a just-in-time basis rather than being piled up on-site. Quantities and
shared properties of materials can be extracted easily. Scopes of work can be isolated and
defined. Systems, assemblies and sequences can be shown in a relative scale with the entire
facility alone or a group (ibid).
Current and future BIM can leverage the capabilities of existing BIM software to provide a
historical and navigable timeline that chronicles both tangible and intangible aspects and
changes in the past with projections into the future. As discussed earlier, BIM is developed as a
way of managing the full development lifecycle of a building project. Used to facilitate new
designs, build changes and communication amongst contractors and design teams, BIM has
proved to provide significant cost savings and efficiency gains. It has always been assumed
that trying to model existing buildings and structures in Revit is time consuming and extremely
costly, however this is attitude is changing. To fill this gap 3D laser scanning may be used for
existing building modeling. By using the latest 3D laser scanning data capture techniques,
surveys can be made in 3D and this information can be converted to accurate Revit models.

(ibid.)
Many studies and initiatives have been carried out that can be linked to digitization of existing
buildings (see: http://3d.si.edu/conference/index.html, retrieved: 28-12-13). For cultural
heritage, 3D content is more and more often used with the latest 3D viewing platforms for
visualizing and manipulating 3D data. Technologies include 3D printers and resulting prints,
virtual reality goggles, and natural user interface (NUI) devices. (ibid). Current technology, e.g.
laser scanning, photogrammetry, analytical 3D imaging, etc., make it possible to
comprehensively assess a building's geometry, existing conditions and specific needs;
including e.g. air pollution and humidity levels, vibrations, cracking, corrosion processes,
electricity consumption, energy efficiency and much more with different types of sensors.
Analyses that are not included but could be incorporated are context analyses, physical loads,
resistance to wind, fire, compatibility measures and concerns between the new structure and
the old (i.e. in adaptations and renovations), intangible qualities and significance of a particular
resource – and the role of high quality crafts. There are endless opportunities for collecting data
that can be processed into information on the measures required to maintain the different
qualities and values of a property (Johansson, 2008).
4.4. BIM FUNCTIONS AND PROMISES FOR PRACTITIONERS
Based on the research performed for this report, it seems certain that the demand for BIM and
sustainable building technologies will continue to grow. BIM is not only beginning to change the
way buildings function, how they look and the way they are built, but also how they are
preserved, valued and understood – not as singular isolated units but as placed in a broader
context, as part of a conglomerate of buildings and landscapes from different time periods
(Johansson, 2008; Engelbrektsson and Rosvall, 2006). As BIM technology and practices
continue to develop, efficient and intelligent technologies will become even more pervasive
worldwide.
Use of BIM for existing Buildings

This point to increased business benefits of using BIM, such as better quality of work and better
profits, more accurate documentation, less rework, reduced project duration, fewer claims and
the ability to offer new and more sustainable services. Cost savings and operational efficiency,
improved visualization and design quality, and client demand are cited as major drivers for the
adoption of BIM. The majority of the world’s leading firms have already started their transition to
BIM from traditional CAD systems, and the numbers of new technology providers developing
add-ons to the systems have also increased. Companies are developing BIMs with various
levels of detail, and the modeling efforts associated with generating BIMs vary.
The UK, United States, Australia and the Middle East have been identified as the top four
markets that will provide the highest growth opportunities for BIM application-related software
products and services (WSP Group, p. 29). In Europe, the building sector represents
approximately 40% of EU:s total energy consumption. It is estimated that approximately 40% of
all activities in the sector are related to rehabilitation, maintenance and reuse (Swedish Building
and Planning, 2007; Swedish Environmental Protection Agency, 2008), and in 2050, as much
Use of BIM for existing Buildings
25
as 70% of the existing building stock will remain. This means that the amount of activities in the
area of architectural conservation, rehabilitation and management will increase (COM 2010).
EU’s directive for enhanced near-zero energy buildings includes a strong focus on existing
buildings and larger building stocks. In 2012, the BIM technology market stood at 1.8 billion
USD, and it is expected to reach 6.5 billion USD by 2020. (European Parliament, 2010)
Based on the number of market studies and reports outlined in the bibliography, it is clear that
BIM represents a new paradigm within the AEC/FM industries. A potential obstacle is that
adopting and developing BIM is costly, but it is inevitable. Building owners are becoming an
important driving force to its increased adoption. This development also applies to Sweden that
has an extensive amount of historic buildings, gardens and habitats, industrial heritage and
larger building stocks; including areas of mass housing. The qualities and cultural values that
these environments represent should be protected, preserved and maintained while facing new
requirements. A major problem, however, is that the building sector is too often focused on
maximizing efficiency, space and usability at the expense of existing assets –emphasizing
economic, functional, technical aspects and demands (Mason, 1998; de la Torre 2002).
However, in order to meet the future demands, the role of informatics, architectural
conservation and high quality crafts skills and knowledge requires further attention.
As per the nature of socio-technological systems, the future of BIM is revolutionary. This lies in
its development beyond 3D modeling and software; i.e. as a multi-disciplinary planning, design,
analysis, construction, preservation/rehabilitation and facilities management process
technology, that will lead to dramatic process changes. This means the shaping of social
practices by expanding possibilities of achieving better communication and collaboration
between different stakeholders and disciplines at an early stage, and throughout all stages of
the building process. Once the basic infrastructure is in place, numerous work processes and
technologies can be brought in, which will result in tighter integration. This may lead to more
sustainable work practices creating an entirely new cultural and institutional environment.
In general, BIM may lead to improved quality and planning processes, energy efficiency,
control, design, construction and management. Nowadays, improving energy efficiency is a
Use of BIM for existing Buildings
26
major driver for renovation and rehabilitation. In a near future, ‘eco-makeovers’ of larger
building stocks will inevitably be carried out, involving laser scanning with measuring equipment
to create a model for its shape to be incorporated into the BIM. BIM’s strength lies in its
possibilities as a complex information management system. As it emerges and becomes more
advanced, it will develop as an intelligent system consisting of a transparent set of
methodologies, tools and work processes that are merged into a consistent and integrated
whole, made accessible for all actors and parties involved - i.e. before, during and after the end
of a project, and as part of the ecological process of continuous recycling (WSP Group, 2013).
In this way, BIM is not only a rich 3D model; it is a complex information structure (6D and
beyond). As more information is added, the data can be “mined” to identify and monitor the
process and project’s performance.
If the information within a BIM is utilized in a more integrated manner, there are large profits to
be made. For example, the client can find competitive advantage by providing customers with
preventative long-term maintenance contracts, or find new bidding or business models for real
estate sales. The buyer can also buy properties with a guarantee based on the concept of
intelligent/ smart and/or ‘environmentally sound housing’, which means that property owners in
the future may change their focus from being event-driven organizations to planning driven
ones. Instead of dealing with daily errors, they would be able to focus on quality and
sustainability requirements. More energy can be devoted to planning and cooperation, to
preventive conservation, renovation/adaptation and maintenance. Then, the user would be able
to both sell and buy quality assured accommodation - while the characteristics, specific
qualities and values of the existing asset/-s remain. This will also create new business
opportunities, jobs and employability for individuals. Moreover, this would ultimately lead to
enhanced wellbeing and a better quality of life by ensuring that these different needs are met
and that the qualities and values are properly preserved and maintained for future generations.
Use of BIM for existing Buildings
27
Given the above, current BIM functions and benefits can be summarized as opportunities:
For collection of large volumes and variety of building related information;
For laser scanning with measuring equipment, e.g. for energy efficiency;
For storage and access of that information;
For improved visualization and productivity due to easy retrieval of information;
For analysis of that information for patterns or deviations identification;
For increased coordination of construction documents;
For integrative work practices such as planning;
For innovative design;
For architectural conservation and ECO-friendly environmental modeling;
For more sustainable work practices;
For effective resource utilization and coordination of activities in the lifecycle of a given
building;
For enabling innovative changes to the bidding process;
For strategic leadership, entrepreneurship and innovation within an organization as well
as on a broader scale.
4.5. PRACTICAL BIM PROBLEMS: NEEDS AND OPPORTUNITIES
In general, the construction industry is facing major challenges when it comes to developing
and updating the existing standards and guidelines and different work patterns that ensure
interoperability between the different phases of planning, design, production, preservation,
rehabilitation and adaptation, maintenance and operation for SD, conservation and
management. The connection between culture and technology represents one of the most
important challenges. The emergence of sustainability practices is dependent on complex co-
dependent and contextual knowledge, strategic interaction, collaboration, inter- and trans-
disciplinary research. Environmental sciences and technology management are two such broad
Use of BIM for existing Buildings
28
and emerging fields where fundamental changes have taken place in the way research is
performed. (Magnusson, 2012)
Sustainability has been very difficult to achieve – particularly with regard to quality, energy,
costs, heritage aspects and related values. The situation is further complicated by the lack of
relevant training, education and research/RTD, appropriate knowledge systems, methods,
processes and skills. A major aspect is that the AEC and Facilities Management (FM)
industries are discipline-driven and different actors dominate at different stages of the process.
Many studies have raised concerns about this critical fact, which includes issues such as low
quality, high costs, low profitability and a predominant lack of innovations (Johansson, 2008).
Major parts of the processes are also project-based (Magnusson, 2013). The actors involved
are part of a system that possesses poor information systems when compared to evidence
provided by, for example, known control and efficiency theories (Bystedt, 2012). The challenge
of providing the right information to the right actor, at the right time and place, and in the right
format, is regularly manifested. There is a need to study problems from multiple dimensions
and disciplinary perspectives, from a practical and a scientific viewpoint, in order to provide a
sustainable impact and results, which also applies to the use of BIM.
Despite the considerable adoption of BIM for the design and lifecycle management of new
buildings, very little research has been undertaken to explore the value of BIM for the re-
design, conservation and management of existing buildings and environments (Fai et al.,
2010). To a limited extent the focus has been on cross-disciplinary collaboration and
integration, creating synergies between the new and the old (i.e. existing environment),
between different disciplines, stakeholders and professionals, projects, methods and
technologies, cultural and conceptual views etc. This applies to the construction process, in
particular, but also to different kinds of planning and design processes, conservation,
innovation and management on a broader scale. In general, a holistic approach to the field of
BIM and facilities management (FM) is lacking.
A key problem is in the logistical management of information, and its intangible flows (Haftor et
al. 2011). An important aspect is the ability to communicate and interact at an early stage and
Use of BIM for existing Buildings
29
in a continuous manner to strengthen and add value to the project and the investments made
for an efficient use of resources. It's about being able to link different types of knowledge,
technologies, methods, networks and initiatives with each other and create a common
understanding of the knowledge and resources that are available at different levels, especially
for small businesses, but also for other actors, such as larger firms. Otherwise there is a risk of
duplication and/or unnecessary competition. The challenge is to merge different BIM systems
in such a way as to maximize profitability and leverage existing qualities and strengths at each
stage of the process.
It is a well-known fact that BIM will challenge relationships and current thinking – their effect on
bidding, contracts and insurance (Magnusson, 2012). Also, it will support the integration of the
architectural design-construction (AEC), preservation and maintenance/operation (FM) teams.
Whilst such changes are expected, research indicates that this is not yet the case. One reason
for this may be that the theoretical and practical basis of information handling and the concept
of ‘value generation’ have not been fully understood. The quality of work is affected in a
negative manner, which in turn has a negative impact on the built environment, and especially
on the specific qualities and values it represents (Waterhouse, 2011). Problems include a lack
of leadership, competence and feedback cycles, flow configuration, variability problems,
collaboration and communication across cultural and organizational boundaries, ownership
aspects, leadership and staying up-to-date, and a lack of evaluation and accumulation of
improvement in processes (ibid). As a result, appropriate BIM systems and devices for
intelligent information sharing; consensus-building and participatory decision-making are
needed to a much greater extent than before.
According to long tradition, the master builder was specialized in the design, construction and
maintenance of buildings. This included all stages of planning, design and management, the
production and handling of hand-made drawings and construction documents. However, this
has changed into high-tech digitized drawings and handling of documents. In addition,
responsibility for the process has been transferred to the building owner and buyer who are
responsible for operation and maintenance. The production phase is normally separated from
the design phase as well as from the long-term conservation and management phase, which
means that knowledge will be lost between the different phases. There is the question of
Use of BIM for existing Buildings
30
ownership and leadership at the various stages of the process. Lack of coordination and
communication causes all kinds of errors and inefficiencies, structural and material damage.
Generally, a more integrated and preventative approach is needed (Johansson, 2008).
4.6. POTENTIALS AND HINDRANCES FOR WIDESPREAD ADOPTION
Although the adoption of BIM has numerous potential benefits, it raises challenges with regard
to organizational, communication and leadership aspects and the way in which BIM integrates
the business processes of individual practices (Arayici & Coates, 2012). Benefits of BIM will
only come through close collaboration, and different actors will need to work together as one.
This will provide greater options for innovation and R&D. BIM will push this development, which
will include a change in habits and routines to make cooperation natural, which in the long-term
will change conceptual views. This would result in higher quality of work. It is expected that new
forms of bidding and contracts will emerge. Digitalization and close collaboration challenge the
prevailing system of intellectual ownership, which may emerge into parallel routes: 1) of
increased specialization of BIM modeling and specialists and 2) of consolidation into giant
firms. There is a prevailing need to develop a consistent holistic approach and to develop
common standards and requirements, for concepts and terminology, information delivery, data
storage formats, bidding and contract forms etc. Unfortunately, there is still a hazy notion about
just what information and data are needed, when and how data will be stored, used, shared
and kept up to date. It is an issue of organizational restructuring, and also of competence, and
thus of education and training/R&D, but unless the gap between technology, end-users and
their processes is over-bridged - BIM usage will continue to be limited (Wakefield, 2005).
Standardization is necessary if SB/AC aspects are to be integrated with BIM processes, which
should include the definitions and semantics of the information used. In order to enable
integration of SB/AC methodologies with BIM, the definitions of information contents should be
further developed. Recently, the International Standard Organization (ISO) has established a
framework for providing specifications for the commissioning of BIM. A number of other
important initiatives have been carried out in the USA, in Europe and likewise in Australia; e.g.
the North American National BIM Standard, NBIMS, the Finnish Common BIM Requirements,
Use of BIM for existing Buildings
31
COBIM, and the Australian National BIM Guide. It is applicable to any range of BIM and
building-related facilities, from a “portfolio of assets at a single site or multiple sites, to assets at
a single small building and at any constituent system, subsystem, component or element. The
framework is applicable to any asset type, including most structures, infrastructure and public
works, equipment and material” (ISO TS 12911:2012). These standards work mainly with
principle methodologies rather than individualized processes.
Workforce development is also critical to the decision to implement a new technology and
approach; otherwise, desired outcomes cannot be achieved. A prerequisite for success is that
the targets set can be translated into concrete action plans and patents, where innovation and
continuing learning should go first. Many of the problems are caused by lack of relevant
knowledge and skills, particularly at the intersection of different sectors and disciplines
(Johansson, 2008, Johansson, 2005). With regard to the building sector in general, there is an
increased need for continuing education and training at different levels, particularly from the
viewpoint of leadership, sustainability and innovation/ entrepreneurship, and R&D, as well as
on the practical use of BIM and its future development. This means that the competence should
be broadened and that the opportunities to work with BIM in existing environments should
increase (Johansson, 2008; Gustafsson & Rosvall 2010; Dyrssen et al, 2011).
A first step would be to increase levels of awareness through formal education, which all
professionals undertake to achieve their necessary minimum qualifications. Concept promotion
of sustainable building, architectural conservation and BIM within higher education is vital,
together with requests for syllabus integration and inclusion, as well as continued training and
research/R&D, e.g. in the form of Continuing Professional Development (CPD) modules
accessible for all actors and stakeholders, and for educators as well (UNESCO, 2005; Kassem,
2012). BIM will be a way to change all construction/architectural/built environment-oriented
education, creating the need to integrate construction technology and design, urban planning,
architectural conservation, traditional and modern building technology, natural and social
sciences, economy, management, arts and crafts. This includes knowledge about architectural
conservation technology and maintenance, where accurate documentation, assessment and
depiction of existing resources and qualities are essential.

5. RESEARCH FRONTIERS
This section summarizes the research front in the area of the usage of BIM. To be very clear,
one key finding from the study reported here is that there is very little academic research
targeting the use of BIM for existing buildings. An account of the findings generated by this
study is provided below.
5.1. EARLIER AND CURRENT BIM RESEARCH
‘Computer Integrated Construction’ (CIC) research efforts in the 1990’s focused on
incorporating entire graphic data and non-graphic data throughout an organization or a project.
In 1993, a Japanese CIC project exploited a full scale, on-site automation combining
information and robotics through all the stages of design, procurement and construction
(Miyatake & Kangari, 1993). Another important research project was carried out by Chinowsky
and Reinschmidt in 1995, where “qualitative spatial reasoning” was developed in order to
embed the design knowledge into the graphic objects. Another research project, funded by the
Korean government developed fully integrated CIC-systems using real-world projects. This
encompassed the full spectrum of construction business functions, including planning, sales,
design, estimation, scheduling, material management, contracting, cost control, quality, safety,
human resource (HR) management, financing/ accounting, general administration and R&D.
This project fully utilized state-of-the-art technologies coupled with newly researched
management methodologies. It was successful in terms of technical capability and a holistic
approach, however, practical effectiveness was not proven to be economically feasible (Cho,
2000).
The research carried out by Chinowsky and Reinschmidt (1995) was further developed by
Taylor and Bernstein in 2009, focusing on patterns of visualization, coordination, analysis and
supply chain integration as a BIM trajectory. A holistic BIM framework focusing on the issues of
practicability for real-world projects has been proposed by several researchers and research
groups since then; the first was proposed by Succar (2009), followed by another by Jung and
Use of BIM for existing Buildings
33
Joo (2011). These two frameworks can be further developed and delineated so that the
practical use of BIM effectively incorporates different BIM technologies in terms of their different
properties, relations, standards and utilization across different construction business functions,
considering various project, organizational and industry perspectives. In 2013, Succar
published a Ph.D. dissertation on the same topic. See Table 1 for an overview.

Current BIM research is mainly being conducted in Europe (Scandinavia, Germany and
France), and at present, the United Kingdom (UK) is the leading region of BIM research. A
significant amount of research is also carried out in Asia, Australia and the United States. In the
last few years, several research initiatives have added new dimensions to the usual 3D BIM
approach, progressively including information about 1) construction time (BIM 4D), 2) costs
estimation (BIM 5D) and 3) lifecycle management (BIM 6D). At the Universities of Salford and
Stanford/CIFE and the University of Reading some research has been performed with focus on
hospitals. There is a group at the University of Washington (U.S.) including studies conducted
on behalf of the U.S. Army Corps of Engineers on “Developing Best Practices for Capturing As-
Built Building Information Models (BIM) for Existing Facilities”. In Italy, Dr. Matteo Lo Prete at
Politecnico di Milano has presented a Ph.D. dissertation entitled Synergies between
management and valorization of Cultural Heritage though Models Based on BIM Technologies.
This doctoral research specimen deals with questions on how to create digital models of
existing buildings with different techniques (Lo Prete, 2013). The amount of BIM literature is
constantly growing, especially in terms of academic papers in peer review journals and
magazines.
In Australia, academic research is being conducted at Deakin University, the University of
Newcastle and the University of Sydney, in collaboration with Kyung Hee University in Seoul,
Korea, focusing on developing a theoretical framework of technical requirements for using BIM
as a multi-disciplinary collaboration platform (Singh et al, 2011). In Marseille, France, some
progress has been made in the development of a specific free Autodesk Revit plug-in,
nicknamed GreenSpider, examining how point clouds collected during high definition surveys
can be processed with accuracy in a BIM environment, also for historic buildings. This research
highlights the critical aspects and advantages deriving from the application of well-established
parametric techniques such as e.g. laser scanning and photogrammetry to real world domain
representations (Garagnan, 2013).
The British government has taken an initiative to make BIM obligatory for public projects, and in
the United States, the General Services Administration has introduced requirements for the use
of BIM. Even in the Nordic countries multiple client organizations have taken the initiative to
start introducing BIM, e.g. Statbygg in Norway. Senatfastigheter in Finland and
Use of BIM for existing Buildings
35
Domænebestyrelsen for Bygninger, Boliger og Forsyning in Danmark. In Sweden, a number of
government clients/managers have agreed to jointly develop common guidelines for BIM. At
Luleå University, Professor Thomas Olofsson is leading a research project on industrialized
building processes, which includes issues related to BIM. At Chalmers University of
Technology in Gothenburg, a number of master theses have been produced on the topic and
use of BIM.
Three ongoing European projects of which two are HESMOS (http://www.hesmos.eu) and
ISES are currently addressing all this, including a number of aspects of BIM for energy-efficient
design and sustainable lifecycle management, including BIM-integrated air-flow analysis, which
is integrated with the ongoing Eurostar project SARA. Their management calls for an extended
BIM-based information framework, ICT platforms providing open access to advanced methods,
flexible and holistic involvement of a broad range of end users in the overall process. This also
includes the development of an energy-extended BIM platform (eeBIM), an enhanced
Information Delivery (IDM/MVD) “BIM to energy” process and a set of advanced energy
analysis, simulation, monitoring and cost estimation tools for various lifecycle phases, from
early design to facility management, refurbishment and retrofitting, bound together in a
common, interoperable BIM-based Virtual Energy Lab platform accessible via the Internet.
The third project is a newly-started large European Integrated Project (IP), known as
eeEmbedded (Collaborative Holistic Design Laboratory and Methodology for Energy-Efficient
Embedded Buildings). This project will develop an open BIM-based holistic collaborative design
and simulation platform, a related holistic design methodology, an energy system information
model and an integrated information management framework for designing energy-efficient
buildings and their optimal energetic embedding in the neighborhood of surrounding buildings
and energy systems. A new design control and monitoring system based on hierarchical key
performance indicators will support the complex design collaboration process. Knowledge-
based detailing templates will allow energy simulations in the early design phase, and BIM-
enabled interoperability based on a novel system ontology will provide for a seamless holistic
design process with distributed experts, and a seamless integration of simulations in the virtual
design office (energy-performance, CO2, CFD, control system, energy system, climate change,
user behavior, construction, facility operation), thus extending it to a real virtual design lab. The

partners of these three European projects represent a broad mix of academic institutions.
These projects are hosted by Institut for Construction Informatics, TU Dresden in collaboration
with BIM consultants and software vendors such as Nemetschek, RIB, DDS, SOFiSTiK, and
industry partners from design (Obermeyer Planen + Beraten, Leonhardt, Andrä & Partner,
Granlund Oy etc.) and construction (Royal BAM group, TRIMO Engineering, STRABAG AG).
See Table 2 and Table 3 for an overview.
5.2. SUMMARY OF RESEARCH NEEDS AND THEIR IMPLICATIONS
In general, there is a need for a more integrated approach to research and practice at the
intersection of different disciplines, sectors, business functions and initiatives. The research
and development work carried out on BIM so far has had a significant focus on new buildings.
What happens to existing resources is little researched or discussed today, especially in terms
of management and maintenance. In recent years, many firms have seen the majority of their
construction work switch to retrofit and refurbishment projects instead of new build, so the
demand for research in this area is growing. As a consequence, there is an urgent need to find
out how to better integrate BIM research with facilities management, historic building
technology, architectural conservation, and high quality construction practice (traditional and
modern), combined with entrepreneurship and strategic leadership in using BIM.
There is a need for increased integration of already existing systems, technologies and tools
etc. that are independent and functioning well: for energy efficiency; moisture detection;
daylight and artificial lighting; simulation of safety; accessibility and space; laser scanning; GIS;
and for being able to combine information about new and existing buildings/environments, and
most importantly - the context. The challenge will be to put all necessary information into ‘one’
model; keeping it transparent and up-to date and making it independent and accessible for a
wider audience. This is because SB/SIC need a new type of information compared to a
traditional process. In this context, holistic understanding and the transition between the
different phases and stages of the building process is of key importance. Formulating
comprehensive interactive frameworks of BIM for sustainable urban planning, construction,
preservation/ rehabilitation, maintenance and management (FM) jointly would effectively
Use of BIM for existing Buildings
37
facilitate the strategic utilization of BIM. This applies not only to individual buildings, but also to
larger building stocks, whole cities, streetscapes, landscapes and infrastructure.

Aalto University (Finland) BIM for facilities and organizational management (FM/OM) is
one of their current focus areas aiming to introduce the state-
of-the-art approaches, and identify the key research and
practical challenges, in using BIM for later stages of the project
lifecycle. The BIMforLEAN project aims at strengthening the
Finnish research capability in integration of lean construction
and BIM. To realize this, Prof Lauri Koskela from the
University of Salford (UK) is invited to Aalto University as a
FiDiPro Professor. The overall objective is to identify,
demonstrate and expand the positive synergies between BIM
and lean construction as well as to develop novel practical

on three areas: 1) linkages between BIM and lean
construction; 2) mobile computing for construction; and 3)
interaction between commercial, organizational and

More research is needed to understand how to use of BIM systems for cross-domain tasks
such as the achievement of efficient planning, investigation, assessment, documentation, and
lifecycle energy and cost performance of new and existing resources. This requires
consideration of multiple information sources and resources generated which are maintained
and exploited by various stakeholders over a large number of years (6D BIM). Such information
may for example include documentation of existing conditions; communication, collaboration
and decision-making processes; energy and climate data; occupancy/activity data;
manufacturer data regarding materials, pre-fabricated or equipment components; a stochastic
approach for reliability; sustainability; assessment and research methodologies; potential risks
and future maintenance; architectural quality and heritage aspects and much more.

Actor / Group Description
British Government, BIM Task
Group (UK)
The Government Construction Strategy was published by
the Cabinet office 2011. The report announced the
Government’s intention to require: collaborative 3D BIM
(with all project and asset information, documentation and
data being electronic) on its projects by 2016. Essentially
the UK Government has embarked, together with industry,
on a four year program for sector modernization with the
key objective of: reducing capital cost and the carbon
burden from the construction and operation of the built
environment by 20%. Central to the BIM Task Groups
ambitions is the adoption of information rich Building
Information Modeling (BIM) technologies, process and
collaborative behaviors that will unlock new more efficient
ways of working at all stages of the project lifecycle.

”Digitalisering af Offentlig Byggesagsbehandling”
("Digitization of Public construction works”) was a three-
year digitization project aiming to demonstrate how it was
possible to carry out a construction project with digital data.
The project has won an Innovation Award in Denmark. The
prize was established by Kommunalteknisk Chefforening
(KTC).
It should be noted that BIM does not provide any shortcuts in the process; it simply states the
deficiency of information (Kapp (2009, p.13). There is a need to further investigate the
construction of BIM systems and the information flows that incorporate both technological and
quantitative assets (intelligent objects, energy and performance data etc.) and qualitative
assets (traditional/modern skills, techniques, photographs, oral communication, histories,
Use of BIM for existing Buildings
40
sounds, acoustics and lighting etc.) Lifecycle Assessment (LCI/LCA), energy assessment,
service life assessment, preservation and maintenance manuals, optimization of refurbishment
and sustainability rating are important methods in design for SB/SIC and the sustainable use
and refurbishment of buildings. In order to rationalize the use of these methods and to support
the use of sustainable methods during the design processes, the methods should be integrated
with BIM processes. To become more cost-effective and efficient, BIM needs to be developed
so that more of the work is carried out jointly at the early stages of a process, to become more
preventative and planning-driven when preparing for the next phase.
A key factor is the object’s interaction with its intended use, and its users. This is still an under-
represented aspect in current BIM systems and IFC models. Currently, many user-related
decisions are based on a set of average user requirements and on the assumption that the
future buildings will have to adapt to the needs of the majority of users. There is a need to
include use and users’ semantics in current BIM representation, and to integrate it with the
virtual simulation of the ‘building use phenomenon’. The objective is to provide visualization, to
be combined with a written description, of how the existing or future buildings will actually be
preserved, adapted, renovated, (re-)used and experienced, before commencing construction.
This allows designers to test and evaluate the impact of their decisions on the new or existing
building and future users’ life and activities at an early stage. How decisions are made over
time is also important. This may include information about specific problems, limitations and
needs/constraints, intentions and arguments etc., which should be included in the BIM model
as well. This may improve the quality of the final product by solving critical issues and reducing
both time and costs.
It is evident that creating information technology tools is only one necessary step on a much
more complex path to the improvements being sought. There is a complex relationship
between modeling technology, building systems and services, management and organization
of actors over the lifecycle of the built environment (BIM research group, Aalto University,
Finland). Hence, it is clear that BIM requires more than software to be effective; i.e. the
capability and willingness of all parties to interact and collaborate more closely, at all stages of
the process - even if it may seem too complicated, expensive or time consuming at first.
Institutions and governments must participate, encourage and invest in research/R&D,
Use of BIM for existing Buildings
41
education and training (WSP Group, p. 10-12). Knowledge and experience in inclusion and
leadership are crucial factors for management of the BIM system as an inter-connected whole,
which today is handled by special BIM managers – and to be expanded to include all design
professions, building owners etc. who will need to learn about IL, BIM, architectural
conservation sustainable building principles, as it overlaps other disciplines, including the role
of FM, traditional and modern building technology/crafts.
It is asserted that the cultural heritage sector should be able to play a more proactive part in
future BIM development instead of being passive or re-active to its consequences, and ongoing
developments (Johansson, 2008). More and more people agree that it is time to stop regarding
cultural heritage conservation as an obstacle for economic growth. On the contrary, cultural
heritage is nowadays considered a prerequisite for regional and sustainable development. In
the context of BIM, it is asserted that the cultural heritage sector has a strong and important
role: to promote creativity, innovation and competitiveness – also for the development of
intelligent/smart buildings (Dyrssen et al, 2007; Gustafsson, 2010). New research on BIM
should move beyond new build to managing the broader range of facilities and built assets
(including landscapes and infrastructure), providing preventative
conservation/maintenance/renovation/rehabilitation and adaptive reuse. Because of enabling
the sharing of information and because of the great variety of objects, BIM can support the
management of information needed for sustainable building practices and conservation. For
example, the need for rigorous building investigation, documentation and verification at a
preliminary stage is extremely important. For a sustainable result, all design professionals
(architects, planners, engineers, preservationists etc.), material producers, manufacturers,
building owners, economists, facilities managers and craft specialists should be involved. A
research question that emerges is: Can BIM research be joined with cultural heritage research
and scientific insight, artistic understanding etc., as part of a more integrated and holistic
approach?
Existing buildings and environments are all historic resources, and they were not developed in
a virtual world. Their conditions and parameters are real. The passage of time allows buildings
to evolve and transform – what is typically preserved is often unique architectural components
that were crafted exclusively. Existing resources are always unique: their materials, details,
Use of BIM for existing Buildings
42
technique, contents and surroundings. Unlike new build, architectural heritage adds an entirely
new level to the design process—that of existing qualities and conditions, not only heritage
value per se. Some materials deserve to be preserved and/or maintained, but some may be
recycled and reused, however, not all. It is a matter of informed judgment and finding a balance
in each case. Architectural heritage is often seen as being essentially material (tangible), but it
also has non-material (intangible) dimensions of crucial importance for sustainability and high
quality outcomes that need to be considered when using BIM.
Summary of key aspects and their implications:
1. There is a need to further include building owners, use and users’ semantics in BIM
research and development. A key factor is the object’s interaction with its intended use,
and its users. This is still an under-represented aspect in current BIM systems and IFC
models. The objective is to provide visualization, preferably combined with a written
description, of how the asset should be continuously managed, assessed, preserved,
adapted, renovated and maintained, (re-)used and experienced, before beginning its
construction.
2. There is a need to further investigate the construction of BIM systems and the
information flows, which should incorporate both technological and quantitative assets,
as well as qualitative assets.
3. More research is needed for the use of BIM systems for cross-domain tasks such as the
achievement of efficient planning, investigation, assessment, documentation, lifecycle
energy and cost performance of both new and existing resources. New research should
move beyond new build to managing the broader range of facilities and built assets -
including infrastructure and landscapes. There is an urgent need to better integrate BIM
research with facilities management (FM), historic building technology, architectural
heritage conservation, and high quality construction practice (traditional and modern
crafts), combined with entrepreneurship and strategic leadership.

4. To become more cost-effective and efficient, BIM needs to be developed so that more
work is carried out jointly by different actors and professionals at the early stages of a
process, throughout the project’s various phases: from an integrated lifecycle
perspective, i.e. to becoming more preventative and planning-driven.
5.3. PROPOSED DIRECTIONS FOR BIM RESEARCH
The intended research should be multi- and interdisciplinary in system design and modeling,
and include theories, roles, competencies and phenomena such as complementarities and
intersections as part of a more comprehensive methodological approach (Ennen & Richter,
2010). The intended research should offer a holistic model framework, with an emphasis on
sustainability and management of built environments. This model should be applicable to
individual buildings (new and old), to groups of buildings, landscapes and streetscapes, to
larger building stocks and infrastructure subject to change – and concern all stages of the
building process, including conservation and management (involving all potential parties; e.g.
designers, planners, preservationists, economists, crafts). Such a framework is not available
today and is yet to be developed.
The intended research should preferably be based on the theoretical framework of SB and SIC,
in order to develop BIM as a multi-disciplinary collaboration platform. A broad multi- or cross-
disciplinary approach, transcending the borders between sectors, academic and non-academic
institutions, enterprises and disciplines will be necessary, to improve the functional, managerial
and economic realities of BIM. The research should provide theoretical and practical
considerations as to how the basic objectives of SB/SIC can be achieved. This would extend
from a ‘lean production system’ to a ‘value creating system’, promoting architectural heritage,
sustainability, innovation, education, learning and R&D. Since the subjects of sustainable
building and conservation are inter-linked, it is asserted that both objectives can be realized
through an innovative and precautionary approach, incorporating a more preventative and
integrated course of action/R&D. The research effort should remain local, but be conducted in
collaboration with different researchers and research groups abroad (Cole & Lorch, 2003).

5.4. RESEARCH METHODOLOGY AND DESIGN
An appropriate research methodology must explore the BIM modeling process in depth,
considering both quantitative and qualitative information from many different actors, disciplines
and perspectives. This means questioning the functions, purposes, structures, and processes
of existing BIM models and frameworks, interfacing systems and interactions, methods and
tools used by different stakeholders. This implies that the composition and very nature of
existing BIM systems, their structure, content, components and design, is questioned.
A systemic holistic approach combined with trans-disciplinary and embedded case studies (i.e.
for real-world modeling) is proposed for developing a comprehensive BIM framework and
approach (Scholtz et al., 2006). In coming research papers/proposals/ applications, the
following issues may be covered in parallel: 1) New buildings to be projected in an existing
environment, and 2) Existing buildings and environments documented in the form of a
comprehensive integrated BIM model (including the use of laser scanning/’point clouds’,
terrestrial surveying, photogrammetry, existing drawings, visual inspection and assessment
etc.).
The main issues to be further explored, as proposed here, are:
What information is needed to fully implement BIM?
o To whom will information handling be a priority?
o Who owns the information?
o Who needs what information?
o How can the information be trusted to be accurate and up-to-date?
What knowledge and technology is available today?
o How can different theories and activities contribute to sustainable building and
conservation as a whole?
o What are the key opportunities?
o What are the key success factors for the realization of these opportunities?
Use of BIM for existing Buildings
45
What are the main characteristics of BIM business models and technology?
o What are the limitations and challenges?
How is knowledge and data collected and sorted today to provide useful information?
o What knowledge, systems, methods and tools are missing?
What are the general causes of the lack of information in the process?
o How can delivery of relevant building information be obtained?
How would a future BIM model be configured?
o What components, systems, methods and tools should be included in the BIM
process?
o What type of information should be included?
What specific BIM services can be designed so that information is correctly handled
throughout the various stages of the process?
o What is the future of such services and who will be the owners of the services?
What would characterize a future BIM business model?
o Who will pay? Who will find new ways to profit?
o How can the services be cost effective, and what will be the consequences?
What is the future quality and value of these models and solutions to the environment,
to industry and society at large?
o To what extent can environmental principles and ethics be used in these BIM
models and their development, and how?

6. CONCLUSION
The assumed research focus presented here includes the various aspects of the usage of
Building Information Models and Modeling practices for an existing built environment, with a
special interest for Sweden. An explorative research study has been conducted to that end,
and is reported here. The objective of that study was to identify the frontiers of research and
practices with regard to the assumed focus and it included a comprehensive review of
academic and professional literature and interviews with selected BIM experts in Sweden. The
key results of the study may be summarized in the following terms:
Big Expectations: Much professional literature and some academic literature regard BIM
as a “silver bullet” that will solve all kinds of problems related to the whole lifecycle of
built environment.
No Evidence: The conducted study could not identify a great deal of research
addressing the use of BIM; the few studies that are available do not confirm the Big
Expectations assumed for the positive effects of the use of BIM.
Complexity: While the usage of BIM promises to deal positively with the various
complexities inherent in the lifecycle of any built environment, paradoxically the
introduction and use of BIM as such also seems to introduce new kinds of complexities
challenging a successful use of BIM for existing buildings.
Many Stakeholders: It is clear that as any non-trivial built environment has many
stakeholders with their various sometimes conflicting interests, the introduction of BIM
usage also introduces additional stakeholders that are specific and unique to BIM and
its usage.
BIM is more than software: While vendors of the various BIM software packages and
associated accessories such as 3-D scanners, do promise many benefits originating
Use of BIM for existing Buildings
47
from BIM usage, it is much more than a software package. BIM usage includes
resources such as people with their roles, competencies and interests, it includes
various practices with their activities and processes, it includes social institutions with
their formal and informal norms, it includes economic actors such as firms, public
organizations and NGO:s, and includes the actual built environment that BIM is
supposed to serve. All this appears to necessitate a comprehensive approach that is
not limited to only a few disciplines; is they professional or academic.
Research is needed: Perhaps the clearest outcome of the study reported here is that
there is a need for comprehensive research into the use of BIM for existing built
environments, both in Sweden and elsewhere. Put simply, this is because:
o On the one hand the BIM industry and its professionals have put forward many
bold positive effects which can be assumed to be produced by the use of BIM.
o On the other hand there is no independent professional research to confirm or
otherwise the actual vs. the assumed consequences of the adoption and use of
BIM.
o This gap must be closed for several reasons, of which the key ones seem to be:
We need to know, rather than assume, whether we should use BIM, or
not, and why and how?
We need to know, rather than assume, what are the key reasons
preventing the successful usage of BIM?
We need to know, rather than assume, the factors that promote
successful use of BM?
This suggestion for a future research agenda into the use of BIM for existing built environments
concludes this report.

Dr. Darek M. HAFTOR is the PostNord Professor of Informatics, with special focus on
Information Logistics, at Linnaeus University, Sweden. He has spent almost fifteen years in
industry, initially as an analyst and a consultant and subsequently as a manager at a
multinational corporation. That work exposed him to various aspects of operations
development, followed by strategic management activities. Dr. Haftor has a keen interest in
business development as facilitated by information and various information and communication
technologies. His professional work has brought him all over Europe and also to the Middle
East. He has studied a variety of disciplines, from mathematics, statistics and computer
science, through business administration, industrial organization, and psychology to social
theory and philosophy, at various schools throughout Europe and North America. Dr. Haftor
was awarded a doctorate in Industrial Organization and Management from Chalmers University
of Technology, Sweden. He has held academic positions at several universities in Sweden, has
taught MBA classes internationally, and has held several board member positions for academic
organizations and their journals. His academic and managerial work has been recognized,
including receiving ‘The Sir Geoffrey Vickers Memorial Award’ from the International Society for
Systems Sciences and also ‘The President’s Achieving Excellence Award’ from Wyeth
Corporation, both in the USA. Dr. Haftor’s research results include a 'Systemic Enterprise
Modeling Language'; a 'Normative Ground-Motive Analysis' model of pre-theoretical
assumptions, a model of 'Semantic Complexification in Human Affairs', and a novel 'Profit
Equation' that accounts for cognitive time distortion. In broad terms, Dr. Haftor’s current
research focuses two frontiers: 1) Information Economy and its Digital Business Models, and 2)
on normative foundations, inherent in any design and development of organized effort.

Dr. Jan ROSVALL has since the 1960s, together with his wife Associate Professor Emerita
Nanne Engelbrektsson, instigated and continuously developed a comprehensive
interdisciplinary academic infrastructure and multidisciplinary discourse in Conservation of
Cultural Heritage -Built Environment at the University of Gothenburg (GU), Sweden - the very
first of its kind in Europe, resulting in a complete workforce of more than one thousand qualified
employees, teachers and doctors/Ph.Ds. The discourse employs a wide range of methods, and
investigates a broad array of objects and large-scale projects, from the preservation and
restoration of artifacts, monuments, ordinary town and urban ambiances, and cultural
landscapes. In his proactive leadership role, Professor Rosvall has had a profound impact on
the development of the conservation field both in Sweden and internationally. He has
contributed to epistemological and ethical considerations, cross-disciplinary and cultural
reflection and a broadening of views, policy change and development. Through his positions at
the Department of Conservation GU and GMV Centre for Environment and Sustainability,
Chalmers/GU he has been acknowledged as an international scholar and guest professor for
many years: e.g. at Heritage Malta and University of Malta, University of Naples, Politecnico di
Milano, University of Seville (Europe), and at Baylor and Cornell Universities (USA). His
academic teaching and research has included 1) theory and principles of conservation;
including assessment, documentation and systemic modeling, communication and
management, heritage design, arts and crafts; and 2) theory, methods, principles, history and
ideas of Western art, architecture and urbanism. In 1996 he was appointed the very first
Visiting Professor in Conservation ever at the Swedish Classical Research Institute in Rome. In
addition, he was responsible for launching the multi- and transdisciplinary NMK Postgraduate
Enterprising Research School at Chalmers/GU in 2001. He currently holds a position as senior
advisor at the Department of Conservation, Uppsala University (Campus Gotland) and was
awarded the title Professor Emeritus at Chalmers/GU in 2010.
