Purpose & Vision
• Non-profit organization with 160 members from:
– property owners, developers, architects, consultants, contractors,
installers, construction material companies and developers and
suppliers of software
• The highest possible industry collaboration for increased
benefits from BIM
• Vision:
– "We are creating the seamless flow of information
in the processes for community building”

Röfors – Bridge design without drawings
� Built in 1919
� Concrete bridge, three spans.
� Total length 63,5 m width 5,1 m
� Original bridge railing changed in 1970s.
� Landmarked structure.
Phases in the project
• INVESTIGATION: New bridge or repair of the old bridge?
• DECISION: New superstructure on existing abutment reinforced with steel piles.
• DEMAND: Exact clone of the old bridge.• DEMAND: Exact clone of the old bridge.
• IDEA: Why not make it a pilot project with BIM?
Ambitions for the model
• No traditional drawings. Only 3D-model!• Swedish technical requirements for bridges (TK Bro) &
Eurocode.
• Schedule of quantities from the 3D-model.• Use the “Swedish construction standards” (BH 90) with:• Use the “Swedish construction standards” (BH 90) with:
• AMA (code system specifying standard construction tasks and objects, for technical specifications and quantities
scheduling).
• SB11 (encoding objects with status labeling, object status etc).
• Digital delivery.• Model for the future maintenance
Model usage on site
• Quantity export to till calculation software
• Stack out from the model
• 3D reinforcement including specifications
• Site planning with the model
• Time scheduling and controll
• Work task preparations
• Planning - purchase & delivery
• Planning - Economic & Cash Flow

How to feel success
• Based on current conditions what do you think of the level of
ambition for 3D delivery in an open, flexible format?
• Do you think this is a step in the right direction for delivery in an
open and flexible format?
