London Office Mechanical Design

READ-ONLY REVIEW PROJECT. Rebuilt from the accepted, manifest-pinned evidence of the customer demo wf1-DEMO-LONDON-OFFICE-20261020-r4 (28/28) and the frozen Run 3 / Run 4 native packages. Runs are RECORDED (verified evidence, not re-run); the design change and the markup are REPLAYED from the demo transcripts. XX-TEST synthetic project; not engineer approved; not for construction.

Project Intake
The London office in the Hexanta 3D viewer: native Revit ductwork, pipework, fan-coil units and air-handling unit above the ceilings of the synthetic office floor, roof switched off.
