Build an assembly description
Identify the exact panel variant, dimensions, thickness, mass basis, print, coating, laminate, adhesive and backing. Add fixings, edges and the retained or new support. Keep component IDs and source versions where available. A family name such as aluminium composite or fibre board does not describe the complete sign as installed.
Define the intended service
Record location, duration, viewing, handling, care and the actual site’s review requirements. Ask responsible suppliers and competent reviewers what evidence applies to that construction and configuration. Keep graphic appearance approval separate from mounting, structural and site decisions; a correct proof cannot answer every physical application question.
Scope environmental information
Attach sourcing, input-content or lifecycle information to its precise subject and conditions. Ask whether finishing or attachment creates an evidence gap. For a retired sign, describe the full removed assembly and separable components to the intended receiver. Do not translate base-panel guidance into universal acceptance of all finished signs.
Fictional construction discovery
A project compares two rigid faces but later finds one proposal includes a laminate and a different fixing arrangement. The coordinator versions the assembly and reopens affected service and comparison questions. The earlier panel evidence stays attached to its own component rather than being discarded or stretched across the whole sign.
Keep the supplied version reviewable
Preserve accepted assembly, responsible approvals and actual fitted version. Record substitutions, condition and eventual removal outcomes separately. The worksheet makes a complete sign easier to review; it does not provide engineering approval, independent product assurance or a footprint winner. Future refresh decisions should start from the actual identified structure and face.
- List every constituent and fixing.
- Separate physical and image approvals.
- Retain actual supplied versions.
