Executive Summary
This scope gap analysis of the Westside Medical Office Building identified 7 findings across the construction drawings, AIA contract, and MEP scope sheets. The most critical finding is unassigned fire-rated corridor work ($85K–$180K exposure) where the drawings show 2-hour assemblies but no trade scope explicitly includes this work.
Detailed Findings
Fire-Rated Corridor Assemblies Not Assigned to Any Trade
Drawing sheets A-201 and A-202 call for 2-hour fire-rated corridor assemblies throughout the Level 1 patient corridor.
Why It Matters
Fire-rated assemblies are required by the AHJ for Certificate of Occupancy. Unassigned work will emerge as a change order, potentially delaying CO by weeks.
Drawing Reference
A-201 keynote 14, A-202 wall type WA-7
Contract Reference
Division 09 scope excludes fire-rated assemblies per exhibit B
Financial Exposure
$85,000 – $180,000
RFI #001
Please confirm which trade is responsible for the fire-rated corridor assemblies, and provide a complete scope breakdown for this work including blocking, shaft liner, and fire caulking.
Rooftop Equipment Curbs — Roofing vs. Mechanical Overlap
The mechanical scope includes rooftop RTUs and references "contractor-furnished curbs." The roofing scope also includes "all rooftop curb flashings."
Why It Matters
Overlapping scope creates duplicate change orders if both trades bill for the same work during construction.
Drawing Reference
M-501 equipment schedule, roof plan R-100
Contract Reference
Division 15 sec. 2.3 and Division 07 sec. 4.1
Financial Exposure
$18,000 – $35,000
RFI #002
Please clarify: (1) who furnishes the curbs, (2) who installs the curbs, and (3) who is responsible for curb flashing and waterproofing.
MEP Coordination Gap in Procedure Room Corridor
The electrical scope references "coordinate with mechanical for ceiling heights in procedure corridor." The mechanical scope has no corresponding coordination note. The reflected ceiling plan (A-601) shows a 9'-0" finished ceiling, but the ductwork on M-301 would result in 8'-2" clearance.
Why It Matters
Ceiling height conflict will require field modifications to ductwork or structure, triggering change orders from both mechanical and electrical trades.
Drawing Reference
A-601 RCP, M-301 ductwork plan
Contract Reference
Electrical scope exhibit C note 7
Financial Exposure
$22,000 – $48,000
RFI #003
Please provide confirmation of design intent and coordination responsibility for the procedure room corridor ceiling height conflict between the reflected ceiling plan (A-601, 9'-0") and the mechanical ductwork plan (M-301, resulting in 8'-2" clearance).
Elevator Pit Waterproofing Not in Any Trade Scope
The structural drawings (S-101) show an elevator pit with waterproofing notes. The elevator contractor scope excludes below-grade waterproofing.
Why It Matters
Elevator pit waterproofing is required before elevator installation. Missing assignment causes schedule delays and cost disputes.
Drawing Reference
S-101 elevator pit detail, sheet A-501
Contract Reference
Elevator scope exclusion list item 12
Financial Exposure
$8,000 – $18,000
RFI #004
Please clarify which trade is responsible for elevator pit waterproofing as shown on S-101 detail 4.
Kitchen Hood Exhaust — Mechanical vs. Food Service Equipment Gap
The kitchen equipment contractor scope ends at the hood connection point. The mechanical scope references "existing duct" for kitchen exhaust, but this is a new building.
Why It Matters
Kitchen hood exhaust is a health code requirement. Unassigned ductwork will generate a late-project change order.
Drawing Reference
M-201 kitchen exhaust routing, K-101 equipment plan
Contract Reference
Food service scope section 3 connection requirements
Financial Exposure
$12,000 – $28,000
RFI #005
Please clarify who is responsible for the kitchen exhaust ductwork from hood to exterior discharge point.
Medical Gas Rough-In — Plumbing Scope Ambiguity
The plumbing scope includes "medical gas rough-in per drawings." The medical gas contractor scope also includes "all piping."
Why It Matters
Duplicate scopes result in double billing. Requires clarification before both trades are under contract.
Drawing Reference
P-201 medical gas plan
Contract Reference
Plumbing scope 2.4, Medical Gas scope 1.2
Financial Exposure
$15,000 – $55,000
RFI #006
Please define the scope boundary between these two trades, specifying where plumbing responsibility ends and medical gas contractor responsibility begins.
Site Lighting — Civil vs. Electrical Scope Boundary
The civil drawings show 12 site light pole foundations. The civil scope includes "earthwork and grading only." The electrical scope includes "site lighting as shown on E-series drawings" but E-series drawings don't include pole foundations.
Why It Matters
Site light pole foundations are required for exterior lighting installation. Unassigned scope delays site lighting completion.
Drawing Reference
C-501 site plan, E-601 site lighting
Contract Reference
Civil scope section 2 earthwork exclusions
Financial Exposure
$25,000 – $48,000
RFI #007
Please assign pole foundation responsibility and confirm whether a concrete contractor is needed for the 12 site light pole foundations shown on C-501.
