Coordination should be reviewed in models and not on drawings Share information • software limits: file size, number of shop drawings, complex geometries… • open standards are not (yet) perfectly reliable • BIM is easy to blame! Future challenges • Link with structural analysis geometrical model vs. analytical model • Bill of quantities • Planning resources and cost (5D) • BIM on site & Tablets (code bars…) • BIM for Facility Management (equipment, room by room…) Implementation difficulties • How to share/receive models? Legal liability… • Change in practice: construction knowledge earlier in the project • Earlier involvement of subcontractors e.g. MEP First 3 to 6 months often in 2D since MEP, façade… come later in the contract • Different contract type: Integrated Project Delivery? BIG room, metrics, contracts… Questions? dr. ir.
