Doors, Frames & Hardware

The wedge

Every spec, mapped to what manufacturers actually make.

120+ manufacturer price books baked into the model. Architects spec hardware sets, finishes, and frame conditions that no manufacturer actually produces. The AI catches it, maps every line to a real product, and builds the full BOQ and BOM.

Estimators flip between Div 08 11/12/13/14/71, A-sheets, and Section 08 71 00 hardware sets. 200-1,000+ openings. Forty to eighty hours per project.

Question

Schedule A801 lists Door 105 as a 20-min labeled opening with HW-1 (SC oak, 1-3/4"). HW-1 specifies LCN 4040 closer with a 8-1/2 lb operating force. ADA §404.2.4 requires 5 lb max at this opening. Confirm: revise to listed 20-min label with reduced-force closer, or relocate the rated boundary?

Conflict detected · ADA §404.2.4 reach allowance vs. HW-1 closer force. Two paths offered with delta-cost and lead-time in attached BOM.

FAQ

The questions DFH buyers actually ask.

Five things every DFH estimator wants to know before the demo call.

A configurator makes you enter doors one at a time. We're an AI bid operator. We read the spec, build the opening-by-opening table, match every hardware set, run the code checks, draft the RFIs, and produce a priced BOM with alternates. The senior estimator signs the number.

120+ vendors covering Allegion (Schlage, von Duprin, LCN, Ives), ASSA ABLOY (Sargent, Yale, Corbin Russwin, Rixson), dormakaba, Hager, Stanley, ABH, Trimco, Rockwood, Pemko, and 100+ more. Updated nightly from distributor feeds. Discontinued items auto-flagged with ranked alternates.

Yes. The model reads the electrified-hardware riser and the access-control spec (28 13 00). It maps power transfers, electric strikes, mag locks, and request-to-exit devices to the right openings, verifies fail-safe vs. fail-secure per IBC §1010, and produces a coordinated BOM that lines up with the EC scope.

Every addendum is diffed against the prior version. Affected openings light up, the hardware-set assignments re-resolve, code checks re-run, and the priced BOM updates. You see exactly what changed and what the cost delta is, before you re-submit.

A senior DFH estimator. Every output is human-verified before delivery. The AI does the cross-walk and the citations. The estimator signs the number. That's what makes it defensible at AHJ review and at change-order time.
