About

Ensign is a contractor-centric estimating, takeoff, and quantity surveying suite designed to help construction professionals quickly produce accurate cost estimates, proposals, and measurements while reducing manual work and errors by integrating all key workflows into a single, intuitive system that works on both cloud and Windows platforms. It includes on-screen PDF takeoff tools that let users measure runs and count symbols directly from electronic drawings without printing, speeding up quantity measurement for materials and labor, and estimating modules with regularly updated material prices and industry labor norms so businesses can generate detailed, branded cost proposals that reflect real market conditions; the system also supports quantity surveying to compile comprehensive breakdowns and variation reports for payment applications, improving billing accuracy and transparency.

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.
