Coordination Review Scenarios

How to Use These Scenarios

Each scenario below applies the six-step coordination review to a real change. Read them as templates: replace the discipline names and dimensions with your own project values, then work the same questions.

Scenario 1: Wall Relocation

Primary owner: Architecture  |  Affected reviewers: Structure, MEP

An architectural wall moves 300 mm to enlarge a corridor. The shared decision is whether the new position keeps the structural slab edge and the MEP routing valid. Structure confirms the wall still lands on the slab edge without a new pour. MEP confirms the duct branch above the corridor still clears the new wall face. The action owner updates the architectural model; the affected parties confirm no clash; the final approver closes the issue.

Scenario 2: Ceiling Adjustment

Primary owner: Architecture  |  Affected reviewers: Mechanical, Electrical

The ceiling drops 150 mm to hide a new beam. Mechanical checks that the lowest duct still fits above the ceiling; Electrical checks that light fixtures and conduit still clear the beam. The information interface matters here too: the level reference for the ceiling must be updated so every team reads the same height.

Scenario 3: Equipment Move

Primary owner: MEP  |  Affected reviewers: Architecture, Operations

An air handling unit moves to a different rooftop zone. MEP owns the new location; Architecture confirms the curb and access path; Operations confirms the maintenance zone and clearance around the unit. The physical interfaces to check are supports, access, and maintenance zones. The information interface to check is equipment responsibility — the model must still show MEP as the owner of the moved unit.

Scenario 4: Opening Revision

Primary owner: Structure  |  Affected reviewers: Architecture, Fire Safety

A structural slab opening is enlarged to accept a larger duct. Structure owns the new size and confirms the slab can still span; Architecture confirms the opening does not break the floor finish or room below; Fire Safety confirms the fire-stopping detail still achieves the required rating. Record the revision status so every team knows the opening changed.
