Daily recap for June 1, 2026

Today two new step-by-step tutorials landed for small construction contractors: a Bid Takeoff Agent that turns plan sets into bills of materials and subcontractor RFPs, and a Lien Waiver Collector that automates waiver collection before each draw.

New tutorials

Bid Takeoff Agent for Small GCs

Bid Takeoff Agent ingests PDF construction plans and specifications, uses an LLM to extract quantities, and generates a structured bill of materials as a spreadsheet plus draft RFPs for each trade. Built for estimators at small general contractors, it reduces a 2–3 day manual process to minutes. The system handles multi-page plans, extracts door/window/fixture counts, and calculates material yardages — all from a single API call.

Lien Waiver Collector for Specialty Trade Contractors

Lien Waiver Collector automates the lien waiver request process for specialty trade contractors. It sends automated requests to subcontractors, tracks receipt status, and stores signed waivers with timestamps — all integrated with DocuSign for e-signatures and Vercel Blob for secure storage. Project managers can replace hours of manual email chasing with an idempotent API that ensures every waiver is collected before each draw request.
