The 2026 Glazing Shop Drawing Compliance Checklist
Last Updated: October 29, 2026
Quick Summary
A glazing shop drawing compliance checklist confirms that fabrication drawings meet the National Construction Code, Australian Standards and project documentation before anything is cut, ordered or installed. It covers drawing completeness, NCC 2026 performance evidence, AS 1288 glass documentation, system-specific checks and controlled revision status.
- Confirm setout, deflection limits, performance requirements and interfaces are resolved before drawings begin.
- Every sheet must state a written scale and carry dimensions that can be verified independently.
- AS 1288 documentation must nominate glass thickness, make-up and safety classification per element.
- Release fabrication only after the approved-for-fabrication status is recorded on the drawings.
- Most rejections trace to missing dimensions, unspecified glass, interface gaps and unclear approval status.

Why a Glazing Shop Drawing Compliance Checklist Matters in 2026
A glazing shop drawing compliance checklist is a structured set of checks that confirms window, door and curtain wall fabrication drawings meet the National Construction Code, Australian Standards and the project documentation before anything is cut, ordered or installed. A drawing that fails review on site becomes a variation, a delay and, in the worst cases, a non-compliant installation that has to be removed.
The commercial case is straightforward. Shop drawings are the last point where a design error is cheap to fix. Once aluminium framing is extruded and glass is cut, every correction carries a lead time. A disciplined glazing shop drawing review catches those errors on paper.
This guide walks through the 2026 requirements, the coordination issues that trip up most projects, and a practical checklist you can apply to any submittal.
Pre-Construction Planning and Drawing Readiness
Readiness starts before a single line is drawn. A common mistake is treating shop drawings as a drafting exercise that begins after the head contract is signed. In practice, the information a glazing contractor needs, including setout, structural interface and performance requirements, must be locked down at design stage.
Before drawings begin, confirm the following are resolved and documented:
- Architectural setout with finished floor levels and structural slab edges
- Structural deflection limits at each glazing line
- Fire, acoustic and thermal performance requirements per element
- Interface details with cladding, roofing and below-sill waterproofing
- Approved system selection and any project-specific variations
If any of these are still open, the drawing will carry the ambiguity into fabrication.
Scales, Dimensions and Drawing Completeness
Every drawing set must state a written scale and carry dimensions that can be verified independently. A drawing that relies on "scale from plan" invites error, because printed and digital scales rarely match.
Check that each sheet includes a written scale, overall and individual dimensions, panel sizes, setting-out points, and a clear north point or elevation reference. Dimensions should be complete enough that a fabricator could build from them without returning with questions. Missing dimensions are one of the most frequent reasons drawings are rejected at review.
NCC 2026 Glazing Performance Requirements
The National Construction Code sets the performance requirements that glazing must satisfy, and 2026 brings continued emphasis on energy efficiency and condensation management alongside structural and safety provisions. Glazing drawings must demonstrate how each element meets those requirements, not merely assert that it does.
For each glazed element, the documentation should identify the performance pathway used and the evidence behind it. That means referencing the relevant NCC provisions and showing how the selected system and glass build-up achieve the required thermal, structural and safety outcomes. Where a performance solution is used, the drawings must cross-reference the supporting report.
Watch out: a drawing that names a system but omits the glass specification and performance pathway will fail review, and the correction lands squarely in the fabrication window.
AS 1288 Glazing Compliance Documentation
AS 1288 governs the selection and installation of glass in buildings, and it is the standard a reviewer will test your drawings against. Compliance documentation must show that glass thickness, type and support conditions are appropriate for each application, including human impact safety where required.
Each glass type should be clearly nominated with its thickness, make-up and, where relevant, its safety classification. Glass markings and product identification should be specified so the installed product can be verified against the drawing. The National Construction Code and the relevant Australian Standards are the primary references a reviewer will use, so cite them directly rather than paraphrasing.
The Glazing Shop Drawing Review Checklist
Use this checklist on every submittal. It is glazing-specific rather than a generic drafting review. For a deeper guide on reviewing and coordinating shop drawings, see facade shop drawings for architects.
Drawing and documentation checks
- Written scale stated on every sheet
- Dimensions complete and independently verifiable
- Elevations, plans and sections consistent with one another
- Revision number, date and approval status clearly marked
- Glass specification, thickness and make-up nominated per element
- Glass markings and product identification specified
- Performance evidence referenced for each element
- Interface details coordinated with adjacent trades
- Material and finish schedules included
Quality and inspection checks
- Inspection and test plan referenced
- Work inspection request and delivery inspection points identified
- Defect acceptance criteria stated
System-Specific Technical Checks
Different framing systems carry different review priorities. For Alspec and Capral systems, confirm the shop drawings match the current manufacturer's system manual, including drainage paths, expansion allowances and fixing centres.
Readers verifying a specific system should work from the manufacturer's own documentation. Our Alspec technical documentation and support guide covers system manuals and drawing references. The Alspec technical documentation and support guide is a useful starting point for locating system manuals and drawing references.
Drawing Coordination Across Architectural, Structural and Envelope Documents
Coordination failures are the leading cause of RFIs on facade projects. The glazing shop drawing must reconcile with three document sets: the architectural drawings for setout and finishes, the structural drawings for slab edges and deflection, and the envelope drawings for waterproofing and cladding interfaces.
A practical habit is to overlay the glazing setout against the structural model before submission. For a deeper look at preventing these issues, see our guide on how to avoid RFIs in facade construction.
Commercial Glazing Quality Assurance Checklist
Quality assurance on commercial glazing runs from drawing approval through to delivery inspection, but the step most projects get wrong is the submittal workflow itself. A drawing that is technically correct but issued without a controlled revision status can still be fabricated from the wrong set.
Run the submittal as a controlled sequence:
- Internal check against the review checklist before issue.
- Transmittal with a unique document number, revision letter, date and purpose of issue (for review, for approval, or for construction).
- Review comments returned in a register, each closed out or marked as noted.
- Resubmission with revision clouds around every change and a response to each prior comment.
- Approval status recorded as approved, approved with comments, or rejected, with the status marked on every sheet.
- Fabrication release only after the approved-for-fabrication status is recorded.
Use a single revision-control table on the cover sheet showing revision, date, description and approval status. It gives the reviewer an audit trail and stops superseded sheets being used on the factory floor.
Once drawings are approved, the QA sequence continues on site:
- Material and product identification verified against the schedule and glass markings
- Delivery inspection of glass and framing on arrival, with defect acceptance criteria stated
- Installation inspection at each hold point identified in the inspection and test plan
- Work inspection requests raised and signed off before the next trade covers the work
- Defect rectification recorded and closed out
Each step should generate a record. Compliance evidence is only as good as its documentation trail, and a missing approval status is one of the most common reasons a submittal is returned without review.
Common Defects and Reasons for Drawing Rejection
Most rejections trace back to a small set of recurring problems. Knowing them in advance saves a revision cycle.
| Problem | Typical cause | Fix |
|---|---|---|
| Missing dimensions | Reliance on scaling from plan | Dimension every panel and setout point |
| Inconsistent elevations | Uncoordinated revisions | Cross-check all views before issue |
| Glass not specified | Assumed from schedule | Nominate thickness and make-up per element |
| Interface gaps | Trades documented separately | Overlay glazing against structural and envelope sets |
| No performance evidence | Report not referenced | Cross-reference the supporting report |
| Unclear approval status | Revision control lapse | Mark revision and status on every sheet |
Cracks, chips, scratches and other visible defects belong in the inspection criteria, not just the drawing notes. State the acceptance standard so site staff know what passes and what is rejected at delivery inspection.

Frequently Asked Questions
What are the mandatory NCC requirements for glazing shop drawings in 2026?
Glazing shop drawings must demonstrate compliance with the NCC 2026 performance requirements, including structural adequacy, thermal performance and safety glazing. In practice this means showing glass types and thicknesses, framing system details, and evidence that human impact glazing is used where required. Drawings should also reference the relevant Australian Standards and include a compliance declaration signed by the responsible designer. Review the current NCC edition and any state or territory variations before lodging, as these can change what evidence is accepted.
How do I ensure my glazing shop drawings meet Australian Standards for structural integrity?
Start with AS 1288 for glass selection and installation, then confirm the framing system supplier has current test and engineering evidence for the spans and wind loads on your project. Your glazing shop drawing should show glass type, thickness, heat treatment and interlayer, plus fixing details and structural sealant or gasket specifications. Include wind load calculations and deflection limits on the drawing set or as an attachment. A documented review against AS 1288 glazing compliance documentation before submittal catches most structural gaps early.
What documentation is required for glazing compliance in commercial construction?
A complete submittal typically includes the glazing shop drawing set with plans, elevations and sections at a stated written scale, product identification and glass markings, a compliance declaration, structural and thermal calculations, and quality assurance records. Material certificates and test reports for the aluminium framing and glass should be attached. Many projects also require a work inspection request and delivery inspection records as part of the commercial glazing quality assurance checklist. Coordinate the package with architectural, structural and building-envelope documents so dimensions and interfaces match.
What common errors lead to glazing shop drawing rejection?
The most frequent causes are missing dimensions or no written scale, glass types that do not match the specification, absent compliance declarations, and details that conflict with structural or architectural drawings. Visible defects in the documentation, such as unclear panelization or unlabelled materials, also trigger requests for information. Drawings that omit product identification and glass markings are hard to verify against approved products. A pre-submittal review using a glazing shop drawing compliance checklist reduces rework and approval delays.
How does the 2026 building code update affect facade design documentation?
The 2026 update tightens the evidence expected for glazing performance, so drawings need to show how the design meets current energy, safety and structural provisions rather than just referencing an older edition. Expect closer scrutiny of thermal calculations, glass selection and system test data. Check the transition dates that apply to your project and jurisdiction, and note the NCC edition on the drawing set. Early coordination with your facade consultant keeps the documentation aligned with the code version that governs approval.
