01 · Walkthrough

The model, end to end.

Architecture, structure and plumbing, federated and coordinated, from the street front to the kitchen to the drainage stack.

Model walkthrough · ARC + STR + MEP

02 · Three disciplines

Architecture, structure and plumbing, linked.

Three models linked and exported to IFC: architecture at LOD 400, preliminary structure, and plumbing at LOD 300, checked against each other with rule-based clash checks before every issue.

03 · Detailing

Detailing at LOD 400.

Furnished kitchens and toilets with real wall build-ups, sections through the stair, and every coordination item resolved before issue. The AI read caught a 9% scale error in the source drawings and verified 75 dimensions against the CAD.
