Glass area & lite counts
Glass designation, make-up, panel count and measured area, grouped by opening and elevation. Gross and fabrication bases stay distinct.
Division 08 / provincial project specifications / m² / m and sq ft / linear ft, as agreed
Window Wall Estimating Services Canada
Window wall and commercial window schedules reconciled by floor, type mark, receptor and interface.
Quote response and delivery date confirmed after document review.
Glass, metal and openings — separated.
Framing profile register
Heads, sills, jambs, mullions and transoms by system and profile. Cut lengths and waste require an agreed basis.
Doors & hardware sets
Entrances, doors and hardware by mark, with supply, installation and unresolved responsibilities visible.
Measurement output: m² / m and sq ft / linear ft, as agreed. Pricing, manufacturer deductions and procurement quantities are confirmed separately.
What your window wall estimating package covers
| Package | Measurement scope | Basis to confirm |
|---|---|---|
| Windows and doors | Count punched windows, window-wall modules and associated balcony doors by mark. | Commercial windows and window wall remain separate system groups. |
| Interfaces | Record head receptors, subsills, closures and slab-edge connections. | Deflection dimensions and performance requirements come from the design documents. |
| Repetition | Build a level-by-level register of repeated and exceptional modules. | Do not multiply a typical level across plant, transfer or podium floors without checking. |
Canada: tender and specification basis
Agree the primary measurement unit before takeoff; a dual-unit export must convert each quantity once and preserve its original basis. Separate glass supply, fabrication and installation inputs.
Include province, municipality, tender documents and specified thermal or envelope requirements. Canadian project enquiries are reviewed for availability and pricing support before acceptance.
Specified window systems and Division 08 window sections. Specification references describe the tender scope; they do not certify design, product or code compliance.
INSPECT THE OUTPUT
A drawing reference behind every row
Inspect the illustrative elevation breakdown, workbook and annotated drawing. These examples demonstrate the output structure and are labelled as illustrations.

Takeoff & quality control
Measure glazing quantities and framing lengths
State the measurement basis before calculating. Gross opening, daylight glass, fabrication glass and framing reference paths answer different questions.
Takeoff & quality controlSeparate glass types in a glazing estimate
Similar-looking panels can require different make-ups, coatings and tested assemblies. Retain the exact project designations in the takeoff.
Takeoff & quality controlGlazing accessories takeoff checklist
Sealants, gaskets, setting blocks, flashing and closures can disappear between the glass and metal schedules. Quantify them using the actual detail and trade scope.
Takeoff & quality controlPre-bid glazing takeoff quality checklist
Quality review should test traceability, revision coverage and scope ownership before a workbook goes to suppliers or the bid team.
