Flag explanation

Mechanical clause 2 states RA-1 duct bottom elevation is +9'-2" AFF, which clears BM-4 only if BM-4's bottom-of-steel is +9'-0" AFF as noted here. However, structural clause 3 flags an internal discrepancy on the same sheet where BM-4 is alternately called out as W12X26, a deeper section that would raise/lower the effective clearance and could change the bottom-of-steel elevation relationship relied upon by the mechanical routing. Until the beam size/elevation is field-verified and confirmed, the duct clearance calculation in the mechanical clause cannot be confirmed as correct, creating a functional coordination conflict between the two disciplines' assumptions about BM-4's elevation.

Clause '3' (structural):
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.

Candidate clauses from other disciplines in the same submission (only these may be cited):
[id: ff697613-9a6f-43c9-9d68-1c62622dcf2e] architectural 4: 4. See S-101 for column and structural grid locations.

[id: 9c98e50b-aa8d-4e06-ab20-40cfdec784d2] mechanical 2: 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.

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?
