Commercial door orders combine many coordinated details, and small schedule errors can affect leaves, frames, hardware and installation. Overseas projects add documentation, packing and shipping requirements, making a controlled approval process especially important.
1. Pricing from an unclear schedule
Door marks, quantities and revisions must match the plans. If different openings share one mark despite different sizes, ratings or hardware, quotations will contain assumptions. Issue a dated schedule and identify incomplete fields instead of copying generic values.
2. Confusing opening size and door size
State the measurement convention and include wall thickness. Structural openings, frame sizes and leaf sizes are not interchangeable. Typical jamb and head details help suppliers interpret the schedule consistently.
3. Leaving handing until late
Handing affects hinges, locks, frames and hardware preparation. Confirm the project convention and check the swing on plans. Pairs, unequal leaves and access-controlled openings need additional clarity.
4. Treating the frame as a standard accessory
Frames depend on wall type, finished thickness, anchors, profile, rating and hardware. A frame chosen without wall details may not fit the opening or installation sequence.
5. Providing an incomplete hardware scope
Clarify hinges, locks, closers, exit devices, seals, thresholds and access-control preparation. State which items are supplied, prepared or provided by others. Do not approve leaf and frame drawings before critical hardware interfaces are reviewed.
6. Assuming certificates apply to every configuration
Match ratings, labels and supporting documents to the proposed opening. Vision panels, louvers, pairs and hardware can affect the approved configuration. Ask suppliers to state what evidence is included.
7. Ignoring packing and receiving needs
Define opening labels, floor or zone grouping, accessory packing and delivery sequence. Frames and loose hardware should be identifiable against the packing list when containers arrive.
8. Losing control of revisions
Record schedule dates, drawing revisions and approved changes. Require written confirmation when dimensions, finishes or hardware change. Production should be released against a clearly identified document set.
A better procurement workflow
Prepare the schedule, clarify assumptions, review coordinated shop drawings and approve samples or documents before production release. Compare suppliers using the same scope rather than unit prices alone.
