flat-rate annual subscription; vendor's own site is quote-only, but Capterra publishes a starting price Win & Set Up the Work

Preconstruction cost, schedule, and design-decision management platform that centralizes budget trending, scenario evaluation, and risk/contingency governance across owner, architect, GC, and trade stakeholders through Design-Build, CMAR, IPD, and other collaborative delivery models, then hands accepted decisions off to Autodesk Build or Procore for construction.

Agent-hostile

2.6 /5 composite score

Well-funded ($30M+ raised, SignalFire-led Series A) preconstruction decision-management platform with named enterprise GC customers (DPR, McCarthy, Barton Malow) and deep Autodesk/Procore/Sage/WinEst/DESTINI integrations; the vendor's own pricing page is still a quote-only CTA, but Capterra lists a starting price of $5,000/year (flat rate, no free trial), and no public API/CLI/MCP was found.
