ArosBid

ArosBid is an AI construction estimating and bidding tool that runs trade contractors through the full bid workflow, from tender intake to post-award buyout. Aimed at MEP and specialty trades — mechanical, electrical, plumbing, roofing, steel — it structures bidding as ten stages: intake and document review, scope gap detection, equipment BOM creation with labor-hour citations, vendor RFQ management and quote leveling, budget mapping, and a readiness check before submission. Its core job is catching the errors that lose bids: it flags missing clauses, warranty gaps, and calculation mismatches across the 25-30 documents in a typical tender before the bid closes. Two design choices stand out. Calculations are deterministic integer-cent math rather than predictive modeling, so the numbers are reproducible, not guessed; and "nothing auto-sends" — every stage requires a recorded human approval, which fits how estimating teams actually sign off. It integrates with Outlook, Excel, and OneDrive, and pulls from bid sources like BuildingConnected, Dodge, and PlanHub, and its post-bid debrief links losses back to cost-library and vendor-history updates. For BestAIFor readers in the trades, ArosBid is narrow by design — it is not a general project-management suite — and pricing is not published, so a sales conversation is required to scope it.
