KNTRCTR

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.

Penko

Penko is a French AI-powered proposal writing software for public tenders in the construction industry (RFP response software). It helps construction companies, architects, project managers and engineering firms write the technical proposal ("mémoire technique") required in French public procurement bids. Penko first analyzes all the tender documents and produces a bid/no-bid summary: lots, award criteria, constraints, deadlines and risks, each linked to the exact source passage in the original PDF. It then writes a technical proposal specific to each tender and each company, based on the tender documents and the company's own content (past proposals, staff and equipment, project references, photos). It suggests differentiation angles, follows the response structure imposed by the buyer, and exports a fully formatted Word document ready to submit. It also compiles the product data sheets required by the specifications into a single PDF. Cloud-based (SaaS), web browser only, available in French for companies in France. Data hosted in the EU, GDPR compliant. Monthly subscription from €80 per month, 15-day free trial, full version, no credit card required.

QScope

QScope runs a construction project from the first estimate to the final account, in one place, for everyone on the job. Built by a practising quantity surveyor, it brings together the work that usually sits across spreadsheets, email threads, shared drives and WhatsApp groups: estimating and cost plans, built in the app or imported from your own Excel; tenders, bid comparison and contracts; site drawings, photos, tasks, RFIs and documents; applications, valuations and payment certificates, with payment dates from your own contract terms; variations, subcontractors, retention and advance payments; completion, defects, risk and insurance; the final account; and loan monitoring with drawdown recommendations for lenders. Clients, architects, lenders and subcontractors join by link and see only what is meant for them, with no account to set up and nothing to pay. Every change is recorded: who, what and when. For contractors with or without a QS, client-side QS and project managers, and monitoring surveyors acting for lenders. Every feature on every plan, with a 30-day free trial and no card required.

SmarteBuild Construction Management Software

SmarteBuild is Australian estimating and construction management software for residential and small-commercial builders, and the estimators and trades who price for them.

Trueleveler

Trueleveler is an AI-supported project operations platform for construction, covering every phase from pre-construction through closeout with 28 AI engines and 23 trackers in one connected workspace. In pre-construction, the RFQ Generator turns scope documents into structured, bid-ready Requests for Quotation, the Bid Leveling engine compares vendor quotes side-by-side to catch scope gaps and pricing outliers, and the Contract Review engine flags risky or unfavorable subcontract terms before signing. During construction, the RFI Drafter speeds up Requests for Information, the Daily Log Synthesizer compiles field reports from multiple sources, and the Change Order Review engine checks change orders against awarded rates for cost control. Field teams can paint progress directly onto drawings with the Progress tool, translating visual updates into schedule- and pay-app-ready percentages. For billing and reconciliation, the Pay App Review engine cross-checks payment applications against actuals, retainage, and lien waivers, and a built-in finance ledger exports directly to QuickBooks and Sage, with no redundant data entry. At closeout, the Closeout Builder, Warranty Compiler, and As-built Reconciler compile the documentation needed for a clean project handoff. Trueleveler also includes a sales pipeline with Go/No-Go gates and deal-health scoring, and line-item estimates convert directly into branded proposals; win a deal and the job budget seeds itself automatically. The platform is built for construction firms that want less time on paperwork and more time on the job: drop in documents and let the engines handle the reading, drafting, and cross-checking. Every engine's output feeds the next, so data flows through a project instead of being re-typed at each stage. Trueleveler is accessible on web, mobile, and desktop, processes data in-memory and does not retain it unless a user saves it, complies with GDPR and CCPA, and never uses customer data to train AI models.
