Flag explanation

Mechanical clause 5 requires roof structure capacity verification with the structural engineer before setting rooftop equipment, referencing the RTU-1/BM-7 issue; this directly depends on the structural clause's unresolved verification status for the 2,000 lb assumed allowable, indicating a coordination gap that needs closure.

Clause '8' (structural):
8. Existing roof structure to remain except as noted; new point loads from mechanical equipment require verification against the original roof design documents, which are not available for this building -- the 2,000 lb allowance noted above for BM-7 is an assumed allowable
pending that verification.

Candidate clauses from other disciplines in the same submission (only these may be cited):
[id: 8134ea51-ab17-4add-9fb1-ab1dcdc9c893] mechanical 5: 5. Verify roof structure capacity with the structural engineer prior to setting any rooftop equipment; see the RTU-1 note above.

[id: d077053e-e241-45c1-92af-6d4ed9ea4fc4] mechanical 1: 1. RTU-1 is a 5-ton packaged rooftop unit located over Grid B3, with an operating weight of 3,200 lb including curb and rigging. This weight should be checked against the structural engineer's roof beam design at this location (see S-101, beam BM-7) before the unit is
ordered or set -- BM-7 is currently designed for a 2,000 lb concentrated point load at this location, which is less than RTU-1's stated operating weight.

[id: 0634ba34-e348-45ef-965c-0b73095bb9fa] civil 8: 8. Existing building setbacks to be field-verified; see the setback note above for required minimums under the current zoning district.

[id: e2824532-8f6f-42fc-af4a-d0c723bb0904] architectural 2: 2. Existing building shell & structure by others; verify all
   dimensions in field prior to fabrication.

[id: 5c4f36b0-8c7e-4e0a-875f-61ada1072b00] fire_protection 6: 6. Confirm occupant load basis with the architect before finalizing exit signage counts; see the note above.

Does this clause create a coordination conflict with any of the candidates above - i.e. do they describe the same physical space, element, or system in a way that is physically or functionally incompatible?
