An architectural terracotta facade is a coordinated wall system, not a panel purchased in isolation. The panel profile, clips, rails, anchors, cavity layers and building interfaces must follow one documented basis of design, with clear responsibility for engineering, approvals, manufacture, installation and inspection.
Establish the facade basis of design
Start with elevations, panel module, joint pattern, finish range and critical transitions. Add building location, height, exposure, structural movements, design actions, fire strategy, thermal and moisture control, acoustics where required, maintenance access and service life expectations. Identify the governing codes, standards and authority approvals for the project jurisdiction.
State whether the support concept is prescribed by the design team or developed by a specialist contractor. Define the substrate and tolerances available for brackets. A hollow panel may reduce face weight compared with some alternatives, but actual dead load must come from the submitted profile and complete support package. Do not build calculations from an old generic weight.
Assign responsibility before design develops
| Decision | Typical lead | Required coordination |
|---|---|---|
| Architectural module, finish and joints | Architect | Manufacturer feasibility, structural grid, openings and contractor tolerances |
| Loads, supports, anchors and movement | Facade or structural engineer as contracted | Panel properties, substrate, brackets, rails, clips and project design actions |
| Membranes, insulation, fire barriers and flashings | Building-envelope and fire-design team | Rail penetrations, cavity depth, slab edges and adjacent trades |
| Product manufacture and release | Manufacturer | Approved schedule, samples, tolerances, tests, quantities and programme |
| Installation and site QA | Specialist contractor | Survey, approved drawings, access, sequencing, inspections and protection |
Actual contracts vary, so convert this outline into a project responsibility matrix. For every deliverable, name who prepares, reviews, approves and supplies information. “By facade contractor” is not enough if panel testing, anchor design or fire-barrier interfaces remain outside that party’s appointment.
Coordinate every edge and interface
Typical panel bays are rarely the hardest part. Draw full-size base, head, corner, parapet, opening, soffit and material-transition details. Show cavity drainage, ventilation, membrane continuity, insulation, cavity barriers, flashings, rail ends, panel restraints and access for replacement. Coordinate window brackets, signage, lights, canopies and building-maintenance equipment before fabrication.
Survey data must feed back into bracket adjustment and special-piece schedules. If structural deviations exceed the assumed range, the engineer should approve a solution rather than forcing rails or changing joint widths on site. Clearly separate fixed and sliding points so movement is not accidentally locked.
Approve evidence for the proposed system
Submit current product drawings, dimensions, tolerances, unit weight, finish description and relevant material test results. Project engineering should cover panels, clips, rails, brackets, anchors and substrate under the specified actions and load combinations. Fire, thermal, acoustic or weather evidence must match the scope claimed; a product result does not automatically certify the complete wall.
The original table reported values for a 300 × 600 × 18 millimetre panel and compared older standards. Do not apply those results to another profile, thickness, orientation or system without a documented technical basis. Check report date, issuer, test standard, specimen, result and current validity.
Use samples and mock-ups as decisions
Approve a representative colour and texture range rather than one ideal sample. A visual mock-up should include real joints, supports, corners and adjacent materials under relevant lighting. Record the accepted panel codes, blend, tolerances and finish. A performance mock-up may be required separately for structural movement, air or water criteria.
Close comments through a controlled submittal register. Mark superseded drawings, record deviations and obtain approval before they reach production. Late changes to module, openings or finish can affect tooling, quantities, testing and batch planning, so show their cost and programme consequences.
Connect manufacture, packing and site sequence
Release production from an approved panel schedule with unique codes for field units, corners, cuts and replacements. Agree batch controls, inspection sampling, packaging, crate weight, labels and delivery sequence. The current lead time should include samples, mock-up review, tooling where needed, production, testing, packing, transport and customs—not only days on the manufacturing line.
Site teams need the same revision of drawings used for manufacture. Survey supports, inspect concealed layers and verify clip engagement, joints and panel condition at defined hold points. Protect installed work and quarantine damaged units. Keep traceability when crates are split across elevations.
Close out for safe operation
At handover, provide as-built drawings, panel and component codes, calculations, inspection records, warranties, cleaning guidance, access requirements and a step-by-step replacement method. Label spare panels and store them under suitable conditions. The owner should know which observations require routine maintenance and which call for facade-professional review.
Hold a closeout review with the owner, contractor and facade consultant. Demonstrate access and panel removal where required, identify approved cleaning products, and record unresolved defects with dates and responsible parties. A usable handover package should let a future maintenance team trace the installed component without reopening the original tender correspondence.
