- Use laser levels, torque wrenches, total stations, photos, and measurements.
- Interactive, commentable checklist with export and QR code authentication.
The checklist
Pre-Installation Safety & Documentation
- Review approved shop drawings, method statements, and permits per approved project specifications and authority requirements; verify latest revisions; capture photos of approval stamps and record revision numbers.
- Hold a toolbox talk and PPE check for cladding works; use a sign-in sheet; acceptance is all attendees signed and PPE present; upload the signed attendance photo.
- Confirm current manufacturer datasheets/ETA for anchors, brackets, and rails; record batch/lot numbers; photograph packaging labels and attach certificates of conformity.
- Verify torque wrench calibration within the last 6 months; check certificate number and date; acceptance is valid calibration; upload certificate photo.
Substrate & Layout Verification
- Survey façade control lines with a total station; mark vertical/horizontal gridlines; acceptance is variance ≤ ±3 mm over 10 m; attach survey CSV/DXF and mark-up photos.

- Measure thermal expansion gaps at rail joints with a feeler gauge; acceptance is within specification ±1 mm; record measured gaps and photograph gauges in place.
- Confirm fastener grade/coating, washers, and torque per datasheet; use a calibrated driver/wrench; record torque values (N·m) and capture head-marking photos and lot numbers.
Thermal & Moisture Considerations
- Ensure isolators/separation pads between dissimilar metals are continuous; acceptance is 100% coverage with no gaps; upload close-up photos at each bracket.
- Verify cavity ventilation/drainage depth with a ruler; acceptance is depth per spec (e.g., ≥ 25 mm) and clear path at base/head; photograph measurements.
- Inspect air/water barrier continuity; patch penetrations with approved tape and roller; acceptance is no tears or gaps; upload before/after photos.
- Check perimeter fire-stopping at slab edges and openings; confirm continuity and product labels visible; acceptance is no unsealed gaps; record product/batch and photos.
Compliance & Sign-Off
- Perform an as-built survey of bracket/rail coordinates using a total station; acceptance is offsets ≤ ±5 mm from model; upload CSV/DXF and annotated photos.
- Verify datum lines for panel setting out using a laser; acceptance is top/bottom/left/right datums within ±2 mm; record readings and reference control points.
- Tag inspected zones with QR code stickers linked to this checklist; acceptance is successful scan; record zone grid reference and attach photos.
- Obtain supervisor and QA approvals prior to panel delivery; acceptance is digital signatures captured; status marked “Ready for Panels”; export the report.

At a glance
- Confirm bracket layout, anchor torque, rail plumbness, drainage cavity depth, and fire-stopping continuity before panels arrive. Early verification minimizes rework, protects weatherproofing performance, and keeps the façade program predictable.
- Acceptance cues translate drawings into measurable outcomes: plumb within 2 mm per 2 m, flatness within 2 mm over 3 m, bracket spacing within ±5 mm, and anchor torque per manufacturer data—each supported by photos and logs.
- Interactive online checklist with tick, comment, and export features secured by QR code.
- Traceability is built in: capture batch and lot numbers, torque readings (N·m), measurement files (CSV/DXF), and signatures, then export as PDF/Excel for distribution and audit-ready records per approved project specifications and authority requirements.
How to use this interactive pre-install framing inspection checklist
- Preparation: Gather shop drawings, specifications, calibrated torque wrench, laser level, total station, 2 m straightedge, depth gauge, moisture meter, PPE, and manufacturer datasheets. Confirm access, lighting, and safe working platforms.
- Project setup: Create zones by grid/elevation, upload drawings, and map tolerances. Add anchor/bracket/rail product references and required evidence fields (photos, torque N·m, mm readings, batch numbers).
- Start interactive mode: Open the checklist on a tablet/phone. Tick items as completed, add comments for issues, geo‑tag or note grid references, and attach photos directly at each step.
- Capture definitive evidence: Record measurements in SI units, photograph gauges and labels, scan QR codes on materials, and link certificates. Use issue flags to assign corrective actions with due dates.
- Resolve and re‑verify: After corrections, rescan the zone’s QR, retake measurements, and close issues with before/after photos and updated readings for transparent traceability.
- Sign-Off and export: Capture digital signatures from supervisor and QA, mark the zone “Ready for Panels,” then export as PDF/Excel. Archive the QR-authenticated report for distribution and audit.
Why early framing inspection prevents rework
The support framing sets every cladding panel’s final position, so early inspection delivers exponential value. Verifying bracket spacing, anchor torque, rail plumbness, and plane flatness before panels arrive reduces rework and protects programme certainty. Misaligned rails force oversized shimming, visible lipping, and oil-canning. Under‑torqued anchors risk slippage; over‑torqued anchors can crush isolators or damage substrates. Poor drainage cavities and damaged air/water barriers route water into insulation and interiors. This checklist codifies acceptance cues that translate drawings into measurable, repeatable outcomes: plumb within 2 mm per 2 m, flatness within 2 mm over 3 m, spacing within ±5 mm, and torque readings matching manufacturer data. Evidence—photos, measurements, and batch records—builds traceability for sign-off per approved project specifications and authority requirements. Use it before any panel is lifted, while access is clear and corrections are inexpensive.
- Find and fix deviations while access is unobstructed.
- Protect weatherproofing and insulation from hidden defects.
- Lock in datums to speed panel setting out.
- Create audit-ready evidence as you verify.
Tools, methods, and tolerances that drive consistency
Consistent outcomes depend on the right methods and calibrated tools. Use a total station to confirm control lines and bracket coordinates, a laser level for plumb and datums, a 2 m straightedge or string line for plane checks, and feeler gauges for controlled expansion gaps. A calibrated torque wrench verifies anchor and fastener tightening per manufacturer datasheets. Depth gauges confirm embedment, while moisture meters validate substrate readiness. Define acceptance tolerances in advance and apply them zone by zone. Record readings in SI units—millimetres and newton‑metres—and attach photos of gauges at the point of measurement. When tools are calibrated and methods are repeatable, issues become visible, measurable, and easy to resolve long before panels appear on site.
- Use calibrated tools with visible certificates.
- Measure and record in SI units consistently.
- Photograph gauges at the measurement moment.
- Apply the same tolerances across zones.
Documentation, traceability, and closeout
Defects often stem from unclear responsibility and missing records. Capture product labels, batch and lot numbers, torque values, and measurement files as you go. Link each note to a grid reference and elevation so future teams can trace issues quickly. Photograph isolators, fire-stopping, and moisture barrier patches before rails obscure them. Store all evidence with timestamps and user signatures. At closeout, export the inspection as PDF/Excel and share with stakeholders; the QR-secured report provides authenticity in the field. This strengthens compliance, accelerates approvals, and prevents disputes by showing exactly what was inspected, where, and with what results—per approved project specifications and authority requirements.
- Capture labels, batches, and certificates early.
- Tie notes to locations and elevations.
- Export PDF/Excel with QR authentication.
- Secure digital signatures for approvals.
