HOW TO READ THIS DOCUMENT

Unpriced BoQ — Structure & Traceability

This document presents the quantified structure of the Northgate Chambers Cat-B fit-out. Every line item has a measured quantity, a unit of measurement, and a specification clause reference. Prices are held internally by Built AI; the unpriced version is issued to Cushman Workplace for scope verification.

Each line item number follows the format WP.NN — the work package number followed by the sequential line item. Specification clause references link to the Project Specification (NG-PS-001 Rev 1). DSW references link to the Detailed Scope of Works (NG-DSW-001 Rev 2).

TRACEABILITY

Every Line Traces Back

Each BoQ line item links to a specification clause (NG-PS-001), a work package scope entry (NG-DSW-001), and a supplier order. The priced version — held internally — additionally links to the supplier's tendered rate, the evaluated comparison, and the committed order value. This traceability chain means that at any point during construction, any cost query can be traced from the BoQ line back through the specification to the source document that defined it.

BoQ line 05.01 → Spec A4.01 (veneer) → DSW WP-05 (joinery inclusions) → SEP-05 (enquiry) → Holroyd return → Order £146,200 → MU-01 sign-off

Disclaimer: This Unpriced Bill of Quantities presents the quantified scope structure only. Prices, rates and committed values are held internally by Built AI Ltd and are not disclosed in this version. Quantities are derived from measured drawings and specification documents; final quantities will be subject to remeasurement where applicable per the contract terms (JCT D&B 2016).

BuiltAI
UNPRICED BILL OF QUANTITIES — COMPLETE

68 lines. Every quantity measured. Every clause traced.

The BoQ is the financial backbone of the project. Every line item connects to the specification that defines it, the scope entry that bounds it, the enquiry that priced it, and the order that committed it. When the Margin Cockpit inherits this baseline, it inherits a structure where every number has a source.
