When you have to work to specifications for a government contract in the context of road construction or road redevelopment, you can call on Standard Specification 250 by the Roads and Traffic Agency (Agentschap Wegen en Verkeer, AWV). This standard contains all information about road construction, sewers, signalling and landscaping. Standard Specification 250 includes the requirements for BIM for these aspects of highways.
Specification 250 talks through the Information exchange through BIM on projects as part of a contractual requirement. BIM-oriented working includes:
- preparing and finalizing the BIM design model before the start of the works
- updating and completing the BIM model during implementation
- delivery of the as-built BIM model upon provisional delivery
- updating the BIM model during the warranty period.
The specification also mentions the requirements for data exchange using the Object Type Library (OTL).
