Bybanen Utbygging (BU) Deliverables and requirements 3D‐modell based construction Dato: 2017‐09‐06 Bjørn Gisle Hodneland BIM Manager Bybanen Utbygging 3D/BIM goals Bybanen Utbygging (BU) wants to promote the use of information‐ og communcation technology, trying to streamline the design and construction. This means extended use of 3D models through all phases of the project and using the model as a platform for exchange of information between, designers, engineers, constructors, owner and others 3D/BIM goals • Ensure quality in designed solutions • Ensure efficient communication in the project • Ensure constructability • Increased safety • Reduced cost The road to 3D/BIM • Useful 3D experience from stage 3 • Comprehensive 3D and model requirements for the engineering and design team.(BIM execution plan) • Use 3D models in zoning and design phase. • Extended requirements for 3D og model deliveries and usage in construction phase. How does this impact stage 4 • Models must be used for construction • Individual models per contract • Reduced number of drawings • Models prioritized over drawings • Drawings delivered only as digital pdf format • Focus on collaboration Technical presentation of 3D/BIM plans for stage 4 When: 09.00 am, thursday 07.09.2017 Location: 1. floor.
