Trace each sectional overhead door from the schedule into its lift type, headroom and backroom clearance, wind-load basis, and operator, then compare counterbalance, glazing, and electrical coordination for the same opening before treating a schedule entry as complete.
Assemble the review package
Gather the door schedule, the building section or detail showing headroom and backroom at each opening, the structural framing plan for header support, exterior elevations for wind-exposed openings, and the issued sectional overhead door specification. This guide covers sectional overhead doors, whose horizontal sections travel up into an overhead track; a coiling door that rolls onto a drum is a different assembly with its own specification section. Review one opening completely before assuming a similar schedule row carries the same lift type and clearance.
WBDG publishes UFGS 08 36 13: Sectional Overhead Doors as a public guide-specification reference (accessed September 24, 2026). Use your project’s issued specification and amendments for the actual comparison; the guide specification does not automatically govern your project. The checklist below is an original suggested review workflow, not a reproduction of the UFGS requirements.
Eight checks to run against the issued set
Use one record per location or system. The CSV contains the same eight prompts plus fields for source revisions, observed evidence, the review owner, the decision, and closure references.
| Check | Sources to compare | Question to resolve |
|---|---|---|
| Lift type and clearance | Door schedule lift-type note + section headroom and backroom dimension | Does the drawn headroom and backroom at the opening match the specified lift type’s clearance (for example, roughly 400 mm 16 inch headroom for a standard-lift 50 mm 2 inch track versus 250 mm 10 inch for low headroom)? |
| Fabrication and thermal performance | Door schedule insulation note + specified section gauge and U-factor | Does the specified steel or aluminum section gauge and insulated U-factor match what the schedule or energy documentation calls for at that opening? |
| Design wind load | Structural wind-pressure criteria + specified wind-load rating | Does the specified wind-load rating and test basis (ASTM E330 or ANSI/DASMA 108) match the design wind pressure for the actual opening location, including any corner or high-exposure zone? |
| Glazing panels | Elevation glazed-panel size and location + specified glazing type and thickness | Where glass panels are shown, does the specified glazing type and thickness match the panel size, and has the applicability of safety glazing been confirmed for that location? |
| Counterbalance and track | Section track dimension + specified spring, cable, and track gauge | Can the specified counterbalance spring, cable safety factor, and track gauge be traced to the actual track size and door weight shown for the opening? |
| Operator type | Door schedule operation column + specified manual or electric operator | Does the specified operator (pushup, chain hoist, or electric) match what the schedule shows, and does an electric operator reference the required entrapment protection? |
| Weather seals and sensing edge | Opening exposure (exterior or interior) + specified seal and sensing-edge option | Does the specified weather-seal and sensing-edge combination match whether the opening is exterior or interior and whether it is electrically operated? |
| Electrical coordination | Electrical plan power and control-station location + specified operator wiring requirement | Are the motor, control station, and safety-device wiring for each electrically operated door reflected on the electrical documents at the location the door specification assumes? |
Worked example: a headroom dimension that does not fit the lift type
Illustrative example: a door schedule assigns the standard lift type to a loading dock opening, while the building section at that opening shows overhead framing that leaves less clearance than a standard-lift track needs above the head of the opening. The specification’s own note ties each lift type to a minimum headroom and backroom dimension that the section does not appear to provide.
Compare the section’s dimensioned clearance against the headroom and backroom the specified lift type requires, and ask the designer to confirm whether the framing, the lift type, or both need to change. Recheck the operator location and control-station clearance for the corrected configuration before closing the item.
Avoid a false conflict
A door schedule’s lift-type note does not by itself confirm the overhead framing was coordinated to match it; headroom and backroom requirements differ across standard, low-headroom, high-lift, and vertical-lift configurations even when the door leaf looks identical on the elevation.
When requirements disagree, follow the project’s document-control and clarification process. Do not assume that drawings always override specifications, or the reverse. Identify the exact sources and request an authorized decision.
Close the issue across the affected documents
Record the location or tag, drawing and specification references, issue dates, observed difference, and the decision needed. Assign an owner and keep the item open until the response identifies the governing requirement. Check the revised drawings and specification references together; a response email alone may leave the issued package inconsistent.
For the overall process, use the guide to drawing and specification conflicts. Mark an inapplicable checklist row with a reason, and distinguish a verified correction from a question that still needs design information.
Where Groundbook fits
Groundbook’s drawing and specification review helps investigate potential disagreements in the documents you supply. Include the relevant specification sections and drawing references, then verify the cited evidence with the responsible reviewers before acting on a finding.
