Definition
The door and window schedule lists for each door and window its code on the plans, size, leaf, frame and glazing type, opening direction, hardware, fire rating where needed and number of units.
Why it matters on a project
It is the basis for pricing and fabricating doors and windows, which are high-value items. Without it each contractor prices his own assumptions and offers cannot be compared.
Measurement and pricing
Gives the count for each type and size directly, or the area in square metres for windows and facades.
Common mistake
Issuing a schedule that no longer matches the plan codes after revisions, so counts differ between schedule and drawings.
Frequently asked questions
What goes in a door code?
A letter for the type and a serial number, such as D01 for the first door and W03 for the third window.
Is the schedule enough for fabrication?
No, the fabricator needs shop drawings with sections, details and actual site measurements.
