One specification, eleven packages
The Project Specification is the combined technical output of the eleven work packages, issued to Cushman Workplace as the single reference the supply chain prices against. It carries 148 clauses, each traced to a drawing and a standard, so a priced return can be checked against a fixed requirement rather than a supplier's interpretation.

What the clauses hold to
The specification is written to performance, not brand, so the supply chain can price and substitute against a measurable requirement. The meeting suites are specified to an acoustic rating of Rw 42 dB, an uplift from the 38 dB outline that the tenant confirmed for confidential legal work. Manifestation follows BS 8300, electrical testing BS 7671, and mechanical ductwork DW/172.
Named products are given as a quality benchmark with an approved-equivalent route, so the specification sets the standard and the supply chain sets the price. The single exception is the fluted oak veneer, where the book-matched AA-grade finish is a design-intent requirement and is specified without substitution.
Appendices and traceability
Three appendices support the specification: the drawings referenced, the standards and codes cited, and the samples and mock-up register. Every clause resolves to a Bill of Quantities line, and every line to an order, so the specification is not a standalone document but the head of a traceable chain from requirement to installed work.
| Appendix | Content |
|---|---|
| Appendix A | Drawings referenced, architectural and M&E, by revision |
| Appendix B | Standards and codes referenced across the packages |
| Appendix C | Samples and mock-up register, SMP-01 to SMP-08 and MU-01 |
The samples and mock-up register is the appendix the site team uses most, because it fixes the standard the installed work is measured against. Eight samples and one full mock-up are scheduled, each tied to a specification package and signed off before the related work is ordered.
| Ref | Sample or mock-up | Package | Status |
|---|---|---|---|
| SMP-01 | Acoustic partition build-up, Rw 42 dB | SPC-A2 | Approved |
| SMP-02 | Glazed screen and door-seal detail | SPC-A2 | Approved |
| SMP-03 | Fluted oak veneer, AA-grade, book-matched | SPC-A4 | Approved |
| SMP-04 | Carpet tile to open plan | SPC-A5 | Approved |
| SMP-05 | Acoustic ceiling tile, Class A | SPC-A3 | Approved |
| SMP-06 | Wall finish and decoration | SPC-A6 | Pending |
| SMP-07 | Ironmongery suite | SPC-A2 | Approved |
| SMP-08 | Luminaire and lighting scene, 420 lux | SPC-M2 | Pending |
| MU-01 | Meeting-suite full mock-up | SPC-A2, A4 | Scheduled |
The traceability is two-way and complete: the 148 clauses resolve to the 68 measured Bill of Quantities lines, and each line resolves to an order once priced. A query on site returns to the clause that governs it, so the answer is the specification rather than an opinion.
The specification is the head of the traceable chain, not a standalone document. Everything downstream, the enquiry packs, the returns, the awards and the Ledger, reads back to a clause here, which is why a change to the specification is controlled as tightly as a change to the contract sum.
Rev 1 is the issued baseline. A later revision reopens only the clauses it touches and re-notifies the packages that price them, so a small change never quietly resets the whole document.
