About

Rebar is an AI-powered estimating platform designed specifically for the HVAC industry to automate the process of performing equipment takeoffs and preparing project estimates from construction plans. It analyzes building drawings and project documents using advanced AI and vision-language models to automatically detect, tag, and count HVAC equipment and components directly within the plans. This allows estimating teams to quickly identify items such as dampers, diffusers, and VRF systems while extracting the relevant properties needed to prepare accurate project quotes. By automating these tasks, the platform reduces the amount of manual work required during estimating and enables teams to complete takeoffs in minutes instead of days. It also includes tools for automatic room identification and equipment marking with associated specifications, helping estimators organize information from large construction plans more efficiently.

About

Zip Takeoff is a browser-based takeoff tool for sitework and heavy civil contractors who need accurate quantities without the cost of legacy desktop software. Upload plan PDFs and measure areas, lengths, and counts with vertex-level editing; automatic area pickup extracts vector geometry from supported PDFs for fast editable measurements, and scaled satellite imagery covers sites where plans aren't available. Group every measurement by pay item, turn areas into volumes and material weights with depth and density inputs, keep Base Bid and Alternates separate, and export pay-item totals to Excel with a marked-up plan set. Nothing to install — runs on Mac and Windows in the browser. Free plan: 10 projects, 5 GB storage, 1 estimator seat, full measurement tools and XLSX export. Pro: $39/mo per estimator seat; viewer seats free.
