Agentic UK Operation and Maintenance (O&M) manual compilation, Health and Safety file production, and Building Safety Act 2022 Golden Thread document pack service for small principal contractors and developers completing commercial or higher-risk residential projects (1–20 staff). Replaces the project information manager or CDM consultant who charges £1,500–£5,000 to compile the statutory O&M manual, produce the CDM Health and Safety file, and structure the Golden Thread asset register required for Building Control sign-off.
Why now
No fresh signal batch provided. Justified by Building Safety Act 2022 Golden Thread requirements now fully in force for higher-risk buildings, with Building Control bodies refusing completion certificates without compliant documentation (https://www.hse.gov.uk/building-safety/golden-thread.htm), and ongoing HSE CDM enforcement activity in 2025.

Commercial value
Every notifiable construction project requires a CDM Health and Safety file; higher-risk buildings (7+ storeys) now require a Golden Thread under the Building Safety Act 2022. Small contractors routinely pay £1,500–£5,000 to consultants or delay practical completion. ~40,000 notifiable projects complete annually in the UK. ACV target £900–£1,800 per project. Budget line: currently paid to CDM consultants, project information managers, or document controllers.
Go-to-market
Target small principal contractors via Constructionline and CHAS member lists, and LinkedIn ('principal contractor' + 'CDM' + UK). Hook: free H&S file checklist audit. Price: £997 per project for H&S file + O&M pack, £1,497 for Golden Thread pack. First 10 via direct outreach to contractors with live projects nearing practical completion. Partner with building control bodies as referral channel.
2-week MVP
User uploads existing project documents (drawings, subcontractor O&M sheets, risk assessments) via a simple file upload form; LLM extracts and structures content into the CDM Regulation 12 Health and Safety file template (sections: project description, contacts, hazardous materials, maintenance requirements). Cut: no Golden Thread database, no BIM integration, no automatic Building Control submission. Manual assembly and QA before PDF delivery. Day-1 outcome: contractor receives a compliant H&S file draft that satisfies Building Control for practical completion sign-off, replacing the £2,000 CDM consultant fee.
Agent score
0.60 — Commercial: large project volume, clear £1,500+ per-project budget, but project-based rather than recurring limits ACV compounding unless subscription model is built. Speed: document ingestion + LLM structuring is 2-week build; Constructionline member list gives cold outreach targets. Defensibility: moderate — document structuring is replicable, but proprietary template library and Building Control relationships create mild stickiness over time.
