The 78 requirements extracted from the tender pack, mapped to source documents and owners. Every line accounted for: 90% addressed in the Built AI pack; 9% raised as RFIs to Grimshaw & Bolt and routed to Question Time™; 1% pending QA confirmation.
Distribution of the 78 requirements across the 7 source documents in the tender pack. The G&B ITT and SDS Doc 23 are the primary sources, with British Standards / CIBSE / BSRIA references providing the technical-compliance baseline.
Cell intensity reflects requirement count. Highlights where the bulk of the technical content sits (SDS × Technical) and where statutory references span sources.
78 requirements grouped into 8 categories. Each entry maps a tender clause to the Built AI pack response location, owner, and current status. Click any category to expand. Commercial, Programme and Technical are open by default.

Roll Call complete. Seven RFIs raised during requirement extraction will be carried into the Question Time™ register at Stage 03, joined by any further clarifications identified during scope analysis and pricing.
Roll Call™ is the second stage of the Bidroom in a Box™ workflow. It indexes every page of the tender pack, extracts every requirement, maps each one back to its source document and clause reference, assigns an owner, and records where the response will land in the submission. Open RFIs are routed to Question Time™ at Stage 03; everything else flows into Scope, Cost Stack and the client deliverables.
