Flag explanation

Structural beam B-14 limits clear height in Data Hall 2 to 14'0" AFF, but mechanical ductwork DS-11 in the same space requires clearance to 14'6" AFF to the bottom of duct insulation. The duct clearance requirement exceeds the available clear height under the beam, making the two requirements physically incompatible.

Clause '1.1' (structural):
1.1 Structural beam B-14 provides a minimum clear height of 14 feet 0 inches above finished floor within Data Hall 2.

Candidate clauses from other disciplines in the same submission (only these may be cited):
[id: 31c0c6f8-2ce0-4848-a79c-a4ed1534ec37] architectural 1.1: 1.1 Reflected ceiling plan for Data Hall 1 requires a minimum 9 feet 0 inches clear from finished floor to the underside of any overhead equipment, duct, tray, or pipe.

[id: f293f8e9-335d-46ec-9bd6-fbdeb528c2db] architectural 1.2: 1.2 Reflected ceiling plan for Data Hall 4 requires a minimum 8 feet 6 inches clear from finished floor to the underside of any overhead equipment, duct, tray, or pipe.

[id: a5b573eb-a957-4db8-8655-21134c1f30c5] mechanical 1.2: 1.2 Ductwork DS-14 within Data Hall 3 shall maintain a minimum clearance of 13 feet 0 inches above finished floor to the bottom of duct insulation.

[id: da668d04-55bb-4aae-98db-9ef5df737b1b] mechanical 1.1: 1.1 Ductwork DS-11 within Data Hall 2 shall maintain a minimum clearance of 14 feet 6 inches above finished floor to the bottom of duct insulation.

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.
