About
DWGdrop is a web-based construction bid and drawing collaboration tool for contractors, estimators, subcontractors, architects, and engineering teams. It supports sending drawing packages and requests for quotation (RFQs) to trade partners, who can review materials and submit quotes through shared links. The browser-based workspace is described as supporting DWG, DXF, PDF, and spreadsheet-based bills of quantities, allowing teams to view and measure drawings and review quantities without a desktop CAD application. DWGdrop also provides RFQ status tracking, drawing revision handling, project questions and answers, and side-by-side quote comparison to help teams coordinate bid invitations and evaluate subcontractor responses. The workflow is intended for construction procurement and estimating teams exchanging drawings and bids with external partners.

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.
