Flag explanation

Fire protection clause bases exit sign quantity, panic hardware count, and hydraulic demand calculations on an occupant load of 60 persons, while architectural clause 2 explicitly states the calculated occupant load for the same floor is 85 persons and flags that these figures should match but currently do not. Using a lower occupant load than the actual code-calculated value could result in undersized/insufficient exit signage, panic hardware, and fire protection hydraulic demand for the actual occupant load.

Prompt sent to model

Clause '3' (fire_protection):
3. Hydraulic calculation / design basis: the design occupant load used for this floor's exit sign quantity and panic hardware count, and as the basis for hydraulic demand, is 60 persons, per the approved space program provided at the start of design.

Candidate clauses from other disciplines in the same submission (only these may be cited):
[id: 96b53171-48b1-4dd1-bc7d-f5c6241f358b] architectural 2: 2. This 85-person occupant load is the basis for the exit signage and panic hardware counts on this sheet. Compare against the design occupant load referenced on FP-101, which the fire protection engineer used as the basis for exit sign quantity and hydraulic
calculations on that sheet -- the two figures should match and currently do not (FP-101 references 60 persons).

[id: 5ca2b832-b816-4963-b23e-90212a5f4635] architectural 1: 1. Occupant load calculation: business area (offices, waiting, sterilization), 3,400 SF gross, using the 100 SF/occupant business factor and a 15 SF/occupant concentrated-use factor for the 480 SF waiting area, plus 1,900 SF of treatment/clinical support at 100
SF/occupant. The calculated occupant load for this floor totals 85 persons. Two means of egress are provided; common path of travel and exit access travel distance are intended to comply with the applicable means-of-egress provisions for a Group B occupancy.

[id: 79dd5322-efb5-4bae-93e6-d64eae7dff40] architectural 5: 5. Corridor 106 clear width shown 3'-4" (40") -- VERIFY code
   minimum for occupant load served (see A-102 egress calc).

[id: 7f4a0783-affb-45f0-8c9a-ca258573be07] plumbing 10: 10. Provide floor drain at Mech/Elec Room 105 per code; route T&P relief discharge and any condensate to this drain.

[id: f942f82a-9748-4e4f-94c3-21b469a688f0] civil 3: 3. Parking required for this Group B occupancy at 1 space per 300 SF is 14 spaces; 16 spaces are provided in the existing, restriped lot.

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?
