• This presentation is focussed on highlighting the benefits of using the latest Laser Scan

Technology in conjunction with Building Information Modelling for making accurate records of

Historical, Heritage, Archaeological & Conservation Buildings & Monuments.

• To understand the full advantages of applying Building Information Modelling to existing buildings,

this presentation will use the example of Royal Hospital Kilmainham.

• The Following presentation will demonstrate what information can be attained from Laser Scan

Data, and what this Data can be used to achieve.

• Much analysis of existing and proposed facilities is based on estimated and guessed

figures for building and material performance.

• Whether or not strategies implemented will be effective at improving the energy

performance of a proposed building can be calculated by testing a detailed Building

Information Model

• Accurate analysis, evaluation and refinement of the proposed building’s performance

is an integral part of the design process. This concept can be applied to any aspect of

a building’s performance, once there is a detailed BIM to work from.

The HDS6000 has a rotating mirror system that covers a 360 x 310 degree field of view

How Does Laser Scanning Work?

• The Laser Scan Data is accurate to within 2.0mm, and therefore can be used to generate an

accurate record of any building or structure

• A BIM generated from a Laser Scan Survey will reduce risk of errors that would otherwise be

caused by a lack of information from a traditional survey

• Additional information that may be requested from the survey will already be in the scan, and can

be extracted to the BIM, e.g. the position of sprinklers, pipe and duct works, etc.

• Existing problems can be identified and solutions can be proposed, using true values

• Accurate records of a structure can be used to benchmark the performance of the structure over

time

Advantages of Using Laser Scan Technology to Record Information

Advantages of Using Laser Scan Technology to Record Information

• Complex geometry/surfaces

• Where a High Level of Detail needs to be recorded

• Congested, tight fits

• Far away or difficult to access • Non-intrusiveness has benefit (e.g. avoid lane closures)

• Delicate surfaces

• Short windows to collect data

• Unsafe to occupy

Building Information Modelling, Drawing is Dead – Long Live Modelling Keith Snook, RIBA Director of Research & Technical, http://www.cpic.org.uk/en/current-projects/bim/building-information-modelling.cfm

“Building Information Modelling is digital representation of physical and functional

characteristics of a facility creating a shared knowledge resource for information about it

forming a reliable basis for decisions during its life cycle, from earliest conception to

demolition.”

• BIM can be implemented to accurately estimate the cost of producing, running, and the lifespan of a facility

• 2-D 2D line work

• 3-D Length, Width, Height

• 4-D Time Scheduling & Sequencing

• 5-D Cost Estimating

• 6-D Life Cycle Management

• 7-D Operations/Maintenance – Lifespan of the building

• An accurate Building Information Model can be used for analysis of the structure, and these results can be used to improve efficiency of the structure

Benefits of BIM

With an accurate BIM of the facility, values for existing passive gains and losses can be calculated. Much analysis of existing and proposed facilities is based on estimated and guessed figures for building and material performance. Results from a thermal imaging camera applied to an accurate BIM can determine the following: • Whether or not strategies implemented will be effective at improving the energy performance of a

proposed building can be calculated by testing a detailed Building Information Model

• Identify existing problems/conflicts and identify solutions – for the present time and the future

• Energy Performance/Audit can be carried out

• Product & Manufacturer’s Information (PMI) can be incorporated, improving efficiency of management of the facility

Scan to BIM to Improve Energy Performance of Existing Buildings

Applications For Laser Scan to BIM

• Heritage and Archaeology

• Architecture and Building

• Asset Management & Mapping

• Site Topographical Recording & Analysis

• Recording Civil Structures, e.g. Rail & Bridge Data

• Performance Analysis via Building Information Scan

• Energy Analysis of Existing Buildings via gbXML

Applications & Benefits of Laser Scan to BIM in Heritage and Archaeology

Applications

• Detailed recording and preserving of ancient monuments, archaeological sites and items of

cultural heritage

• Production of drawings to aid restoration and reproduction work

• 3D data collection for movies, walkthroughs & for virtual tours applications for websites, etc.

Benefits

• Faster, safer, less costly, more accurate, and more complete surveys of complex heritage sites

• Non-contact, remote survey reduces potential damage to sites and improves survey safety

• Reduces site visits needed for data capture

• Full-colour camera options add extra level of information to point clouds for richer analysis

Applications For Laser Scan to BIM in Heritage and Archaeology

Applications

• Producing 2D drawings or 3D CAD models containing the required information

• Internal & External building surveys

• 3D urban modelling & Topographical Records

• Detailed architectural scanning for conservation

• Building Performance & Energy Analysis – Existing & Predictive

Benefits

• Faster, safer, less costly, more accurate, and more complete building surveys

• Minimizes impact on use and operation of the building during survey

• Point clouds combined with full-colour imagery provide powerful, accurate visualization

• Better 3D city visualisation, planning and analysis

• Leverage on Autodesk AutoCAD & Revit, Bentley MicroStation, Rhino & CAD tools
