AI specification writing means drafting construction specification sections from a practice’s master specification, the project model and the design team’s decisions, then checking each named product and referenced standard for currency, so a specifier edits a near-complete section instead of starting from a blank clause.
Most practices already work from a master: NBS Chorus clauses structured to Uniclass 2015 in the UK, CSI MasterFormat sections in North America, or a house template in Word. The slow part is the project-specific layer: selecting the right clauses, filling in what the model already knows (wall types, finishes, door hardware), and catching references to a withdrawn British Standard or a discontinued product.
A model is good at the first two and dangerous at the third if left alone, because it will produce a plausible standard number that does not exist. So every product and standard in a draft is checked against a source you trust, and anything unverified is flagged rather than written as fact.
