AI operating system blueprint for GCs, subs, and specialty trade businesses (HVAC, plumbing, electrical, roofing). Architecture: project management (Procore, Buildertrend, JobNimbus) + estimating (PlanSwift, Stack) + field reporting + CRM + scheduling + Claude MCP + n8n. 10 MCP tool schemas: bid/estimate generator from scope, subcontractor schedule coordinator, RFI drafter, change-order generator, safety toolbox-talk writer, daily field report synthesizer, invoice/payapp generator, punchlist tracker, customer update sender, lien waiver manager. Replaces the WhatsApp-and-Excel coordination layer that every contractor pretends is working.
