About

PreConstruct AI is a web-based construction takeoff and estimating application for subcontractors bidding interior finishes, concrete, and wood framing work from PDF drawing sets. It reads drawing scales and uses plan notes, schedules, and partition legends to help identify and measure walls, ceilings, and concrete quantities. AI-assisted wall suggestions are in beta and are reviewed, approved, or adjusted by the estimator. Approved quantities become material lists for items such as studs, board, insulation, tape, compound, paint, concrete, and rebar, with calculations and drawing-sheet references. Estimators can apply their own material prices, create proposal PDFs, and export data to Excel or CSV. Projects can use imperial units, metric units, or both. The application supports estimating workflows; estimators review measurements and quantities before submitting a bid.

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.
