COS runs a contractor in one system, from tender and supplier quotes to site diary, measurement book and progress billing. Real site costs flow back into the next bid.
Contractors run on dozens of supplier quotes per tender, retyped PDFs and paper site books. Every tender and every site starts from scratch, and the knowledge leaves with the people.
Supplier quotes chased by hand, priced in the sixth version of the same BOQ.
The site diary gets written on Friday, from memory.
Measurement book and progress bills rebuilt from notes at the end of the month.
Last year's real prices sit in someone's inbox, not in the next bid.
AI does the chasing, reading and retyping. People make the decisions.
The loop closes. Real costs from the site flow back into norms and into the next bid, so every tender is priced on what the company actually spent.
