A terracotta panel facade system is a chain of products, design decisions and responsibilities. Panels are only the visible part. Clips, rails, brackets, anchors, backing construction, control layers, fire and drainage details, engineering, testing, installation and handover records must connect across several organisations. A clear scope map makes bids comparable and prevents interface work from disappearing between packages.
Define “system” before requesting a proposal
State what the project means by terracotta facade system. Is the enquiry for fired-clay panels only, panels with proprietary clips, a coordinated metal subframe, delegated engineering, supply-and-install work or a complete exterior wall package? Suppliers use the same word for different boundaries, so a headline description is not enough.
Issue an inclusion and exclusion schedule with the drawings. Identify who provides special shapes, cuts, closures, isolators, fasteners, secondary steel, membranes, insulation, flashings, cavity barriers, sealants, access equipment, tests, mock-ups and spare units. If an item is “by others,” name the other package and the information it must receive.
Map the components by package and interface
Visible terracotta
Panel profiles, dimensions, finishes, colour range, joints, corners, soffits, openings, exceptional pieces and replacement stock.
Attachment
Clips, pins, retainers, rails, brackets, anchors, isolators, adjustment, corrosion protection and movement provisions.
Backing wall
Structure or sheathing, air and water layers, insulation, vapour control, flashings, fire barriers and cavity closures.
Project interfaces
Windows, doors, roof, base, parapets, penetrations, adjacent claddings, expansion joints, lighting, signage and facade access.
Draw a line around each procurement package and mark every crossing. An anchor may be supplied with the facade but installed into structure designed by another engineer; a flashing may be drawn by the architect but formed by a separate trade. Those crossings need dimensions, loads, sequencing and acceptance responsibilities.
Select a procurement boundary that fits the project
| Procurement route | What it can clarify | What the client must still control |
|---|---|---|
| Panel supply only | Product, finish, quantity, samples, packing and delivery | Compatibility with fixings, engineering, cutting, installation and warranty interfaces |
| Panels plus support kit | Coordinated panel engagement, rails, clips and standard details | Project anchors, substrate, loads, control layers, interfaces and local approval |
| Delegated facade package | Defined engineering and shop-drawing responsibility within stated criteria | Design intent, performance requirements, review process and work outside the package |
| Supply and install | Single commercial responsibility for specified material and field installation | Overall wall design, other trades, site conditions, testing authority and contract administration |
No route automatically creates “turnkey” responsibility. The contract must state the design criteria, jurisdiction, professional seals where required, review status, reliance on information from others and whether review transfers any responsibility.
Assign decisions with a responsibility matrix
For each deliverable, name the originator, reviewer, approver and informed parties. Typical decisions include panel module and finish, substrate tolerance, design loads, panel and subframe calculations, anchor selection, thermal-bridge assessment, air and water continuity, cavity fire strategy, tests, mock-ups, production release, site inspection and repairs.
Record dependencies as well as owners, so late information is visible before it blocks engineering, procurement or installation.
Keep “design,” “supply,” “install” and “verify” separate. A manufacturer may provide product limits without designing the building anchor. An installer may survey the substrate without accepting its structural adequacy. An architect’s aesthetic review may not approve engineering. Clear verbs prevent implied scope from replacing professional accountability.
Plan the information exchange at each gate
At concept stage, send elevations, sections, context, loads and target module for feasibility. Before tender, issue coordinated wall details, performance criteria, quantities, scope matrix and programme. During submittals, require product data, complete test reports, calculations, shop drawings, samples, certificates, method statements and a marked response to every requirement.
Before production, close open comments and approve physical range samples, mock-ups, special shapes, panel codes, packing and inspection hold points. Before installation, confirm survey, substrate release, storage, access and sequencing. At handover, collect as-built drawings, product codes, warranties, inspection records, cleaning guidance, replacement instructions and spares.
Control interfaces and substitutions as system changes
A change in panel length can alter rail spans, brackets, anchors, movement and packing. A different insulation thickness can change bracket geometry and thermal bridging. A revised window position can interrupt flashings or cavity barriers. Require every substitution to list affected components, drawings, calculations, tests, programme and warranty—not merely state that the product is “equal.”
Maintain one interface register with owner, due date and status. Use coordinated models or large-scale details for congested areas, but retain dimensioned contract information. The active NIBS enclosure commissioning guideline supports early integration and staged verification because enclosure performance depends on materials assembled by multiple trades.
Level bids and close the archive claims
Compare proposals against the same matrix: profiles, finishes, quantities, supports, engineering, evidence, samples, mock-ups, tests, freight, site services, exclusions, programme, warranty and spares. Price qualifications and missing scope before award. A low panel subtotal may conceal major subframe, interface or testing costs elsewhere.
