Mandatory AI Adoption in Capital Works Projects
The Development Bureau has issued Technical Circular (Works) No. 3/2026, setting out the policy and requirements for AI adoption in the Capital Works Programme.
Scope. Applies to consultancies with a pre-tender estimate exceeding $15 million and works contracts exceeding $30 million, for tenders invited on or after 1 June 2026.
Requirements. Employers must specify the use of AI in consultancy briefs and tender documents, referencing the “Inventory of Adopting AI in Capital Works Projects.” Contractors' AI proposals are reviewed against these baseline requirements.
Continuous update. The Inventory is a living document, refreshed by the Development Bureau as AI technology evolves.
Broader use. Project offices are encouraged to deploy other AI-related technologies beyond the baseline to enhance project performance.

How it works
STEP 01
Continuous ingestion
Pyramid's web-crawler retrieves every public HK construction code, standard, and government circular.
STEP 02
Engineer-supervised structuring
Domain engineers organise content into queryable knowledge sets per discipline — landscape, structural, M&E, fire, safety.
STEP 03
Feeds Check and Ask
Updates flow automatically into your deployments. No version mismatch, no superseded clauses.
>90%
Engineering accuracy
Benchmarked on a 500-question set drawn from HK Building Authority codes, HKSMM4 and DevB circulars. General-purpose assistants — even those grounded in public web — fall short on jurisdiction-specific construction queries.
