4D BIM

Applying BIM to prefabricated components and modular structures cuts construction time by 30–50%, reduces waste, and improves on-site assembly accuracy through automated clash detection and shop drawing generation.

Combine Revit Structure with ETABS or SAP2000 for structural load and wind analysis to Thai EIT standards, cut structural material costs 8–15%, and eliminate structural-MEP clashes before breaking ground.

Constructability Review using 3D Models uncovers problems that will occur during construction before drawings are issued — including concrete pour sequence, crane access, Temporary Works requirements, and insufficient site access routes.

3D Model and 4D BIM transform construction planning from error-prone 2D drawing reading into Visual Construction Sequencing that reduces RFIs by 40–60% and significantly cuts field construction errors.
