What is Building Information Model (BIM)?

Building information model combines all the design information to a database in 3D for machine automation in construction

•Increases productivity

• information model contains:

- Terrain model

-Ground soil model

-Structures and systems

-Map and geographical information

-Other material



What is Building Information Model (BIM)?

•Traditional phase-oriented project

intelligent services project exploiting the whole life-cycle and

all parts, actors and activities

VR Group 2011



Vision in Finland

From 2014 big infrastructure managers buy only

model-based services, which will be exploited

in all phases of the project starting from design

phase and continuing to maintenance period

Case Jorvas



Jorvas station



General scheme



Jorvas building information model

• Pilot project, where building information model was to be exploited

- tender phase

- design phase

- in construction phase

• Part of TUKEFIN (productivity in Finland)

• Project targets of the Finnish Transport Agency (FTA):

- Cheap total price

- Design work is easy to visualize and understandable

- Design work fulfils the requirements given by FTA

- Design work contains no mistakes



Tender phase

• Tender evaluation

- Customer satisfaction 20%

- Work in design phase 30%

- No mistakes 20%

- Price 30%



Evaluation of the work in the design phase

• Tender evaluation was done according to specific evaluation model taking into account:

1. Basic information

2. Use and completeness of the model

3. Geometrical model

4. Compliance / Standards

5. Information delivery

6. Knowledge

7. Process description

8. Roles

9. Innovative approach



Building information model in the tender phase

Basic information mainly from general scheme

• Streets

• Basic map

• Laser scanning

• Bridges

• Platforms

• Electrification masts

• Buildings

• Area borders

For the tender phase model was added

• Tracks

• Missing streets and walkways

• Borders of the railway area

• Drainage



Building information model in the tender phase



Using the model during design work




• Desicion of the location of the underpass

• Connecting streets and walkways

• Additional information

• Walkway types

• Location of the platform changed

• Coordinate system changed




• Model coordinator collects the combination model

• Used in meetings

• Model visible in the FTA extranet

• Model description

• Model visualizing the design for public

pp.kk.2012, Esityksen nimi, Etunimi Sukunimi #

New underpass


New high platforms


Staircases from the street bridge to platforms


New parking areas on both sides of the railway


Bicycle and motorcycle parking with shelters


New shelters on platforms


New light traffic connections from parking areas to platforms


New light traffic connection from Old Jorvas Street to platforms


New lighting on the platforms, parking areas and light traffic ways


New electrification masts on platforms



Guidelines and requirements

• FTA’s Infra-model guidelines for making waystructure implementation model

• Infra 2011 CAD design system requirements

• InfraRYL structure identification guidelines

• Specific guidelines for railway structure model identification

• Guidelines for bridge information models

• Applicable parts of norwegian guidelines about information models



Finished information model given to customer

• Original format of the design program

• Open standard IM2/LandXML-format

• Finished coordination model and visualization model as VM viewing package

• Files attached to coordination model

• Model description



Final model



Comments and experiences

• Good in visualising the final design

• Less paper

• Easy to detect the mistakes, e.g. in the sizes of the structures

• Possible to check the compliance between different design work

• Design may be too detailed in the detailed design phase

• Information is not lost during the design

• Does not replace totally 2D design (?)

• Good tool, not purpose itself

• Requires more work (= more expensive) during design phase

• Requires detailed information in the beginning (e.g. laser scanning)

• How final building information model will be updated and exploited after design is finished?

• Building information model database?

• Easy to obtain amount of construction materials
