Hours spent on the wrong bids
Deciding whether a job is worth chasing means reading the whole spec book first.
Estimating capacity decides how much you can bid.
If you're like most small contractors, one or two people carry all the estimating, usually after a full day in the field. Construction OS takes the administrative work out of every bid so you can bid more of them.
Scope in the fine print
Requirements buried in specs and general notes that surface after the job is won.
Retyping the same bid five times
Invites in email, plans in folders, numbers in spreadsheets. The same information gets re-entered at every step.

Bid record + AI spec review
Each bid gets one record: GC, due date, division and plan uploads. AI reads the specs and general notes and produces a full review, a bid/no-bid document, and a package for each trade listing its findings and RFIs.
A first pass for your estimator, not a replacement. You decide what matters.
You stay in control
AI does the first pass. Your team makes every call.
Built to take the admin off your estimator, not to replace them. Spec flags, bid/no-bid documents and trade packages are a starting point. You review and approve every quantity and every bid before it goes out.
Not another platform to learn. Enterprise bid software is built for large GCs with staff to run it. Construction OS is set up and managed by ProTactiX, so your team just uses it.
Your data, price book, estimates and templates are yours and can be exported at any time. They're never shared with other contractors.
Works with your takeoff software. A takeoff tool subscription is separate for now.
