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

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

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

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

Using the model during design work
• Model coordinator
collects the
combination model
• Used in meetings
• Model visible in the
FTA extranet
• Model description
• Model visualizing
the design for
public

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
