1. The BIM strategy in Bane NOR
• Use model based methods and digital tools for all railway projects
− Integrated part of project management
• Model based «As built» documentation − Bane NOR owns the right to all data− Models for maintenance
• Work actively with development of competence, methods, digital tools and standards for effective use of BIM
• Guidelines and requirement for IT
4
The main points in our BIM strategy
All our large projects use models in all phases
5
Where are we now?

Drawing based projectsThe information is divided. Difficult to quality check against each other. Great risk that conflicts are not detected early – at great cost.
3D models3D geometry that describes and places objects in existing terrain is modelled and placed in a inter discipline model.
Drawings
Technical description
Stake out data
Information models (BIM)The objects carries necessary information about themselves.
Effects: • Easier quality control • Better communication• Possible machine control and
streamlining the building site
Effects: :- all information about the project in
models- Information from the models can be
used to reduce the number of drawings and technical descriptions etc.

2. Our requirements for the use of BIM
• The Bane NOR handbook for digital planning and construction− Define types of models and content of each model− Define requirements for file formats− Set the requirements for none-license software for
access and presentation − Define details like coding, standard for file names,
object definition and so on
Our handbook (Norwegian only):https://proing.opm.jbv.no/wiki/_media/felles/sty-600239_handbok_digital_planlegging.pdf
8
What are our overall requirements?
• Covers all details that are not in our handbook needed to coordinate all large projects− Coordinate systems− Definitions and descriptions on how to
implement new disciplines in models− Requirements for levels of details in
different planning phases− States the type of drawings needed in
additions to models
− This document is revised 1-2 times a year based on needs and input from BIM managers in Bane NOR and our partners
9
Routine document
• Requirements for access to models− We can not specify which software
consultants and contractors can use − We require access to the models at all
times− We prefer cloud based, license free
software if possible.− We require necessary number of licenses
or logins
• On delivery we demand all data, including original formats
10
Access to models and data during construction

• Bane NOR works towards open international file formats for railway and infrastructure; IFC and / or GML
• IFC and GML is not fully developed for all infrastructure disciplines.
• Formats like DWG and LandXML are still in use until the development of IFC and / or GML are completed
• Bane NOR support Nordic and International standardization
11
A table from our routine document regarding possible formats for delivery for some disciplines. Tables like this will revised several times on the way towards open standards
File formats
• Infrastructure need standardized properties on objects for life cycle− This is work in progress
• Bane NOR works towards standardized properties and is in the process of defining: − Which properties do we need in planning, building and
as-built?− Example: A culvert has 70 different properties in our
maintenance database – we need to specify how many we need during planning, construction and for as-built
12
Object properties
• Our contracts encourage the use of model based work methods like VDC and ICE. − Bane NOR has certified 2 technical project
managers on VDC, and are currently in the process of certifying 3 more
13
Model based work methods
3. Challenges and our plans regarding BIM
• Our goal is to have model based as-built documentation− That means all necessary information regarding an
object is saved as properties on the object
• Models for maintenance− We have just started a pilot project to define what is
needed in a maintenance model
15
Requirement for as-built documentation
Illustrations: Bane NOR
• We aim to: − Give as clear and concise requirements as
possible− Make our models and design data
accessible as a part of the contract− documentation adapted to the necessary
quality level and degree of freedom for the project
16
BIM in contracts- how can we help our contractors?

The most important challenges regarding BIM
17
• Open standard for file formats and properties for railway life cycle
• Contracts needs to be developed further• Model based as-built documentation
needs better requirements • some of our requirements still demands
drawings
• We will continue to build competence using BIM in all aspects of our organization
