Flag explanation

RA-1's bottom-of-duct elevation of +9'-2" AFF is above BM-4's bottom-of-steel elevation of +9'-0" AFF, meaning the duct does not clear the beam at all (it would need to be at or below +8'-10" to satisfy the 2" clearance, and even below +9'-0" just to avoid physical collision). This directly violates the clearance requirement in structural clause 9 and physically conflicts with BM-4 as documented in structural clause 3.

Clause '2' (mechanical):
2. RA-1 is a 24"x14" return air duct routed along Grid Line B between Grid 2 and Grid 3, with a bottom-of-duct elevation of +9'-2" AFF. This routing crosses the same bay as structural beam BM-4, whose bottom-of-steel elevation is noted on S-101 as +9'-0" AFF. Because
RA-1's bottom-of-duct elevation (9'-2") is above BM-4's bottom-of-steel elevation (9'-0"), the duct as drawn does not clear the beam -- coordinate a revised duct routing or elevation with the structural engineer before installation.

Candidate clauses from other disciplines in the same submission (only these may be cited):
[id: 415c496c-b1a6-461a-91a1-9309989cc1ff] structural 9: 9. Bottom-of-steel elevations noted above are to the bottom of the beam flange, above finished floor. Mechanical and electrical trades should maintain a minimum 2" clearance below bottom-of-steel for all ductwork and conduit racks crossing beam lines -- see M-101,
which shows the RA-1 return duct crossing BM-4's bay with its own bottom-of-duct elevation noted; confirm that elevation clears BM-4's bottom-of-steel by at least 2".

[id: c0dba465-0fb3-41ea-84f6-239eb774c8d5] electrical 8: 8. Coordinate underground duct bank routing with civil site utilities, C-101.

[id: ef1a85ae-92bf-4a9c-b039-84a876adae63] structural 2: 2. Beam BM-1 (Grid B, bay 1-2): W10X22, 24'-0" long, bottom of steel +9'-0" AFF.

[id: 2067eb80-f9e2-4803-9e84-7212f0d801d9] electrical 5: 5. The new electrical service duct bank routes underground from the utility connection to the main distribution equipment; see C-101 for the site routing. C-101 notes a crossing between this duct bank and the new domestic water service with no separation called out --
coordinate the required horizontal and vertical clearance between these utilities with the civil engineer.

[id: 7f90f154-e493-43c1-a813-58091925da17] structural 3: 3. Beam BM-4 (Grid B, bay 2-3): W10X22, 24'-0" long, bottom of steel +9'-0" AFF -- note that the framing plan callout for BM-4 elsewhere on this sheet reads W12X26; field-verify and confirm the correct size with this office before fabrication, as the two callouts for the same
mark do not agree.

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? Call report_cross_discipline_conflicts with your findings, or an empty conflicts list if there's no real conflict.
