2. 20Check joint width uniformity using feeler gauges; accept variation ≤ 1 mm from target width; log readings at each panel-to-panel joint.
3. 21Assess panel plane flatness after fastening using a 2 m straightedge; accept deviation ≤ 3 mm; capture photos showing straightedge contact and gaps.
4. 22Confirm pattern continuity and orientation across seams; accept misalignment ≤ 2 mm; take orthogonal photos demonstrating motif alignment.
5. 23Inspect corners and edge trims with a template gauge; accept tight returns with visible gaps ≤ 2 mm; ensure sealant (if any) is neat and continuous; document with photos.
6. 24Perform tap test to detect buzz/rattle; install damping pads where specified; accept no audible vibration at typical touch points; log pad locations.

Finish, Protection, and Handover

1. 25Verify coating finish for uniform color and gloss; check dry film thickness with gauge per specification; record 5 readings per elevation and photograph samples.
2. 26Clean panels using approved pH-neutral detergent and microfiber cloths; accept no streaks or residue; upload before/after photos.
3. 27Apply and label temporary protective film if required; ensure edges sealed and removal date displayed; photograph labels and protected areas.
4. 28Compile as-built dossier: measurements, torque logs, coating readings, batch labels, approvals; confirm compliance per approved project specifications and authority requirements; obtain digital sign-offs.

Control Lines, Support Accuracy, and First-Panel Strategy

Accurate control lines underpin a flawless decorative screen installation. Establish vertical and horizontal benchmarks with a laser/total station and verify the support framing before any panel is unpacked. Plumbness and flatness tolerances drive the final appearance; even a few millimetres of cumulative error can telegraph as stair-stepped joints. Start with a first-panel strategy: set the initial reference panel perfectly with adjustable brackets, shims, and a digital level. From there, work outwards while constantly checking back to the control lines. Record deviations and corrective actions as they occur to avoid stacking errors. Use a 2 m straightedge to check plane, and capture photos of gauges and laser lines at each bay. This disciplined approach minimizes rework, protects finish quality, and ensures predictable joint gaps that match the design intent.

• Survey grids; confirm deviation ≤ 3 mm over 3 m.
• Verify framing plumb within 2 mm per m.
• Lock in a perfect first panel as datum.
• Shim methodically; record thicknesses and locations.
• Photograph lasers, gauges, and corrective actions.

Managing Thermal Movement, Joints, and Rattle Prevention

Metal screens expand and contract with temperature, so clearances and slotted fixings are essential. Confirm expansion joint locations and slot lengths match the shop drawings, then verify actual clearances using feeler gauges after snug-tight and final torque. Uniform joint width is both an aesthetic and functional requirement; measure at regular intervals to catch trends early. Where details include isolators or damping pads, confirm placement at contact points to prevent buzz or rattle from wind or vibration. Avoid hard-fixing across long runs; allow panels to float as detailed. Document measured gaps, torque values, and pad locations, linking them to photos. When movement provisions are correct, the system resists seasonal stress, fasteners stay seated, and the façade retains crisp, consistent reveals.

• Measure joint gaps at set intervals.
• Check slot engagement post-torque.
• Confirm isolators and damping pads.
• Allow floating points where detailed.
• Capture gap and torque evidence.

Finish Integrity, Dissimilar Metals, and Closeout Documentation

Protecting surface finish is critical for longevity and appearance. Enforce non-marring handling, edge guards, and clean, padded storage. Verify coating uniformity and dry film thickness with a calibrated gauge, and avoid contact between dissimilar metals by using isolating tapes or gaskets at brackets and trims. After alignment is accepted, conduct a controlled clean with a pH-neutral solution and microfiber cloths; harsh abrasives or unfiltered water leave visible marks. If temporary protection film is required, seal edges and tag removal dates to prevent adhesive transfer. Closeout is more than a signature—compile torque logs, coating readings, batch labels, and photographic evidence linked to grid locations. This traceable record streamlines client acceptance and future maintenance while demonstrating conformance to approved project specifications and authority requirements.

• Use non-marring gloves and slings.
• Gauge coating thickness and gloss.
• Isolate dissimilar metal interfaces.
• Clean with pH-neutral products only.
• Assemble a traceable as-built dossier.
