Unanswered Root Cause
A response addressed the symptom but ignored the underlying design flaw.
Case Lifecycle & Protocol Analysis
During multidisciplinary drawing coordination, tracking comment integrity across architectural, structural, and mechanical sets requires strict accountability. When reviews are marked resolved without sufficient verification or cross-sheet synchronization, downstream conflicts escalate into costly field modifications.
In this incident, a reviewer identified an uncoordinated duct penetration intersecting a primary shear wall boundary element. The design team adjusted the duct offset locally on the mechanical plan, quickly clearing the visual interference. However, they never analyzed why the duct was routed there in the first place: the mechanical riser shaft was sized too small for the floor distribution, forcing the engineer into forbidden structural zones. Treating only the clash markup on one sheet left the undersized shaft unaddressed, creating three additional penetrations on adjacent floors.
Key Finding & Observations:
- Response captured the surface clash symptom but avoided root routing geometry analysis.
- Closure was approved on a single-sheet basis without reviewing overall shaft riser capacity.
- Audit trail showed no inter-discipline conversation between the HVAC designer and structural engineer.
