The publication series “Common BIM Requirements 2012” is the result of a broad-based development project entitled COBIM. The need for these requirements arises from the rapidly growing use of building information modeling in the construction industry.

Part 13 describes BIM requirements emanating from the construction phase, utilization of BIM during the construction phase, and tasks for the contractor to deliver information for the as-built model. There is a need to make the models from the design phase available for production planning and coordination. The requirements for modelling done by building and S contractors are presented as options to be agreed on separately in every project. Contractors are to deliver information for the as-built model to the client about adjustments and changes that are agreed on and have taken place during the construction phase.
