Commercial doors fail when the leaf, lock, closer, hinges, access control and fire logic are selected in isolation. The hardware schedule should translate the opening's risk, traffic and life-safety role into one coordinated set.
Why This Must Be Specified Opening by Opening
A project requirement is useful only when it identifies the opening, intended use, performance target, tested configuration and party responsible for approval. Generic catalogue language cannot resolve different risk zones, wall conditions, hardware sets or operating logic.
Project Specification Checklist
- Opening identity: Record door mark, location, handing, size, wall, frame, traffic and environmental exposure.
- Operating hardware: Define hinges, lock, cylinder, lever, closer, stops, seals, threshold and protection plates.
- Life safety: Coordinate fire rating, smoke control, panic hardware, free egress, hold-open and alarm release.
- Access control: Document reader, credential, electric lock, contact, request-to-exit, wiring and power-loss state.
- Commissioning: Assign adjustment, functional testing, labelling, keys, credentials, spares and training.
Evidence to Review Before Purchase
- Opening schedule and hardware set
- Approved product data and certificates
- Access-control cause-and-effect matrix
- Commissioning and handover records
Match every report to the exact product proposed. Check dimensions, opening direction, leaf and frame construction, hardware, seals, anchors and supporting wall. Record any difference and obtain formal acceptance before production.
Common Failure Modes
The most common failures are choosing a rating by habit, approving a certificate for another configuration, changing hardware after testing, ignoring the wall interface and leaving commissioning until handover. An opening schedule and evidence matrix expose these gaps while they can still be corrected.
What to Include in the RFQ
Send the destination, project type, door marks, quantities, finished openings, wall construction, required standards, hardware and access-control schedule, finishes, delivery stages and documentation list. This lets the supplier respond with a configuration rather than an unsupported headline claim.

FAQ
Is a supplier declaration enough? No. Request evidence that covers the proposed complete assembly and have it reviewed by the responsible designer and authority.
Can hardware be changed after approval? Only when the evidence or responsible authority permits the substitution. Treat every change as a configuration review.
