Configuration of material specification, practice and reuse outcome across the three material vignettes
| ANALYTICAL ELEMENT | STRUCTURAL STEEL | PORTLAND STONE | MARBLE |
|---|---|---|---|
| Practical understandings | Inventory-led design, testing and recertification | Selective dismantling and site-based assessment | Limited coordination of panel protection; shift to alternative uses |
| General understandings | Verified structural reliability, with aesthetic limitations | Weathering and variation accepted as part of material history | Reuse redefined from panel retention to material transformation |
| Rules | Certification, traceability, warranty and procurement requirements | Facade performance, installation, cost and programme limits | Programme, protection and liability constraints |
| Teleoaffective structures | Client ambition supported by increasing professional confidence | Reuse balanced against cost, programme and rental priorities | Commitment remained, but the whole-panel objective was revised |
| Recomposition | Earlier investigation, shared inventory, workshops and testing | Repeated assessment, technical adaptation and negotiated variation | Revised specification, decorative reuse and terrazzo production |
| Reuse outcome | Component identity and structural function retained | Conditional component reuse within the facade | Whole-panel reuse replaced by material transformation |
