KNTRCTR Reviews & Product Details

KNTRCTR is subcontractor bid management software for prime contractors (general contractors) in heavy civil and general construction, with Rex AI, a bid intelligence assistant, built into the job itself. The job runs from scoping through invites, bids, comparison, award, kickoff, and a locked performance review. Rex AI sits on that job the whole way instead of in a separate window somebody has to remember to open. You decide what gets compared: Before the job goes out, the prime optionally sets bid expectations: the exact scope items and budget lines every bidder has to answer to. Mobilization, traffic control, restoration, whatever the job actually turns on. That structure is what turns twelve quotes in twelve formats into one field you can read across. Rex AI helps the sub fill it in: Filling out somebody else's form is the part subs hate, so Rex AI does the first pass for them. A bidder who subscribes can upload their own quote and have Rex AI populate the prime's bid expectation rows from it, then check the finished bid against the original request before it goes. If traffic control was on the request and never made the draft, the sub finds out while there is still time to fix it, instead of getting a phone call about it two days later. Invited bidding is free either way. Rex AI for bidders is a leg up, not a requirement to bid. Rex AI fills it in for the prime when the sub skips it: Some bidders will skip the section. Some will email a PDF and call it a day. Rex AI reads that attachment and fills the same bid expectation rows on the prime's side, so the column gets completed rather than left blank. You end up comparing complete columns either way. Then Rex AI reads the field against what you asked for: Stage 1 is a field scan. Every bid measured against the bid expectations you set, not against a generic checklist: pricing outliers, scope coverage gaps, unanswered lines, budget alignment, and what the attached files actually say, in one structured read. Stage 2 is a deep read of one company. Rex AI goes into that bidder's attachments and pulls the detail behind the number. Run all of your bids through this deep dive to get the full review. This is where the money usually hides. A bid that looks low is often a bid that left mobilization out of the total. Rex AI puts the exclusion on the screen before that number does any heavy lifting. Ask Rex AI about this job: Rex AI chat stays on the job in front of you. Ask why one number sits well under the rest, what a file says, whether a scope item ever got answered, or how a company performed the last time you used them. Answers come from this job's request, bids, files, and performance record. Not from a blank page. Rex AI analyzes. You decide. No auto award, no ranked winner handed down. The rest of the platform: Private lists and invites for your go to crews. Open job posts when you need coverage on a trade. Bid intent tracking so you know who is submitting and who is passing before bid day. Bid leveling and bid adjustments that normalize pricing while every original number stays visible. Supplier quotes in the same comparison. Job kickoff with notes, checklist, and document handoff. Job discussion. Company profiles covering equipment, certifications, personnel, and past projects. Multi user access for estimating, procurement, project management, and field teams. Every job closes with a performance review that locks to the record. The next time that subcontractor comes up on a bid, their score sits beside their price. Scores are shared as scores, without written commentary. Who it is for: Prime contractors and general contractors running sewer and watermain, excavation, site servicing, hydrovac, asphalt, haulage, underground utilities, and general construction. Built for outfits carrying several estimators, a project management group, and multiple crews going at once.
