A fire shutter fails its drop test at commissioning. The alarm contractor says the release circuit was never priced into their scope. You say wiring past the disconnect was never yours. The general contractor wants an answer before the inspector leaves the room. None of this is unusual — it's what happens when a specialty doors bid gets built off the door schedule alone.
The schedule prices cleanly: size, R-value, wind load, cycle rating, done. That cleanliness is exactly what lulls estimators into treating the whole trade as a catalogue exercise. The real risk isn't the door. It's everything mounted to it, wired to it, or triggered by it.
The assemblies themselves aren't in question
- Overhead and sectional doors, complete — doors, tracks, springs, motors and controls per the schedule: sizes, R-values, wind loads, cycle ratings, vision panels. Read every column; wind load and cycle rating change the assembly, not just the price.
- Coiling doors, grilles and counter shutters — rated and non-rated assemblies complete with their hoods, guides and operators.
- Automatic swing and slide operators — fitted to pedestrian doors. Pin down which openings get one, what activates it, and whose frame it mounts to; that last question is coordination, not just supply.
- Controls and safety devices — photo eyes, safety edges, loop detectors, push plates, actuators. This accessory list is what really prices the opening; two identically sized doors can carry very different costs depending on the activation and safety package specified.
At the frame: where the boundary sits
Standard swinging personnel doors and their finish hardware belong to the doors-and-hardware trade — a separate scope even when both trades sit in adjacent columns on the same schedule. Aluminum entrance doors are the glazing trade's, with one exception worth remembering: an operator mounted on an aluminum entrance door still lands in your scope, even though the door itself doesn't. Someone has to prep that aluminum frame for your hardware, so pin down the mounting and prep split rather than assuming it.
Support steel at the guides — the jamb angles and hood supports — gets supplied by either misc metals or specialty doors, and the assignment isn't consistent from tender to tender. It's exactly the kind of item both trades leave off their bid because each assumes the other carries it. Check track and hood clearances against the drawn head heights before you commit to a size, too: a schedule dimension that's technically correct can still leave no room for the track curvature or hood once the opening's fully detailed.
At the motor: the split nobody states cleanly
Electrical owns power up to the disconnect. From the disconnect to the motor is the part that gets argued, on nearly every job with a powered opening — read the exact split language in this tender every time rather than assuming it matches the last one.
High-cycle fabric or rigid doors are priced against a duty rating — cycles per day or per hour — that changes both the mechanism and the warranty attached to it. A schedule that states an opening size and material but skips the cycle rating is missing the number that separates a standard door from a genuinely high-speed one; the two aren't interchangeable at the same price. Spring cycle counts and operator warranties beyond standard manufacturer terms show up the same way — stated once in a general note, never repeated against every door line.
Dock equipment — levelers, seals, shelters, bumpers — frequently ships as its own package through a specialty dock equipment sub, even on tenders where the dock door itself is squarely yours. Confirm who carries it before assuming it travels with the door.
At the panel: fire shutters and alarm interfaces
A fusible-link shutter and an alarm-released one are different systems at different costs. The alarm-released version needs a monitored circuit interface, not just a mechanical link, and that interface has to be coordinated with whoever owns the fire alarm panel. Pin down the release method — don't default to fusible-link — and confirm who owns the alarm tie-in wiring and who answers for it if the shutter fails its drop test at commissioning.
The commissioning question runs deeper than the wiring itself: release circuits, drop tests, and who signs off on the interface between the door and the fire alarm system carry a real testing and sign-off cost, separate from the release hardware.
Coordinating the opening
| Trade | What to reconcile before you price |
|---|---|
| Electrical | Power, disconnects, interlocks and activation wiring — confirm exactly where their scope ends and yours begins on every powered opening. |
| Misc metals | Guide angles, jamb steel and hood supports — confirm supply assignment per opening rather than assuming a single answer applies to the whole schedule. |
| Masonry & concrete | Embeds and grouted guides at openings — sequencing and dimensional accuracy both matter here, since a misplaced embed is a field problem, not an office one. |
| Fire alarm | Shutter release circuits and verification testing — confirm who commissions the interface, not just who supplies the release hardware. |
Read the schedule for what it's good at — sizes, ratings, accessories — then check every powered and rated opening individually against electrical, misc metals and fire alarm, rather than assuming the first opening sets the pattern for the rest. The schedule prices the door. The boundary items above decide whether it closes, powers and releases the way the drawings assume.
