Daily recap for June 1, 2026

Today we shipped two step-by-step tutorials for small construction businesses: a bid takeoff agent that turns plans into bills of materials and RFP drafts, and a lien waiver collector that automates chasing subcontractors before each draw. Both are built with production-grade AI packages you can run yourself.

New tutorials

Bid Takeoff Agent for Small GCs

For general contractor estimators who still spend days measuring paper plans and manually typing up scopes for subcontractors. This agent ingests PDF plan sets and spec documents, uses an LLM to extract quantities, and outputs a structured bill of materials as a downloadable spreadsheet, along with draft RFPs for each trade. It cuts a 2–3 day process to minutes.

Lien Waiver Collector for Specialty Trade Contractors

Project managers at electrical, plumbing, or HVAC subcontractors spend hours each week chasing lien waivers from their subs before a draw request. This collector automates the whole loop: it sends DocuSign envelope requests, tracks status, stores signed waivers with timestamps in Vercel Blob, and can draft reminder emails via AI. No more missed waivers holding up payments.
