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
