Live in private beta · Heavy-civil GCs · United States · Onboarding new partners

Level every subcontractor bid on your heavy-civil project — and defend the award.

Bid Reasoner reads each sub's bid PDF, normalizes the line items to your scope, and scores all 5–15 bidders across price, scope, schedule, compliance, performance, and risk. Pick a winner under any of 7 decision modes, see the evidence behind every score, and auto-generate the award memo that holds up when the owner asks why.

What's inside

Built for the way estimators actually think.

Every adjustment is labeled. Every projection shows its work. Your senior estimator can still argue with it — that's the point.

Reasoning Workspace

Per-package recommendation page with AI bidder evaluations across six dimensions, reasoning evidence backed by quotes from each PDF, click-to-explain confidence scores, and a what-if challenge box. Switch between seven decision modes to see how price-priority vs risk-priority changes the winner.

  • Custom Weighting — tailor each of the six weights (price, scope, compliance, schedule, performance, risk) to your project's priorities.
  • Mode chips preview, don't run — switch modes to see the weights, re-run only when you're ready. No AI burn.

Override capture & audit trail

When you award against the AI's recommendation, an override category and reason are required — not optional. Every disagreement creates a permanent audit record. When an owner asks "why this bidder?" six months later, the answer is one click away.

  • Decision Review Needed alerts surface every package waiting on a human look before award — on the dashboard AND inside the package, so nothing slips.

Auto-generated decision documents

Seven Word document types — Reasoned Award Memo, Bid Reasoning Report, Evidence Report, Bidder Scorecard, Executive Summary, Clarification Recommendations, Project Handoff Rationale — populated from the underlying data. Real .docx, not screenshots.

Deterministic risk findings

Not opaque AI: unbalanced unit prices (≤ $1.00), peer outliers (>2× or <0.5× peer median), total-bid outliers (>20% deviation), and front-loaded mobilization (>10% of total). Click any chip to filter the matrix to those flagged items.

Deep-dives into the parts of the workflow heavy-civil GCs search for by name.

Who it's for

Heavy-civil general contractors.

Built for GCs receiving sub bids on bridge, highway, tunnel, and transit packages — where scope is contested, bids run 5–15 deep per package, and bid day matters.

Works in any U.S. state on day one — every bidder is normalized against the peer median of your own bids, so no government data is required to start. Government pay-item baselines are already built in for New York and New Jersey, with more states added as partners come online. Reasoning, scoring, evidence, and the override audit trail work on every project, regardless of state or code system.
