About
BidVariance is browser-based Monte Carlo estimating software for consultants, agencies, engineering teams and specialist contractors pricing fixed-price work. Users build task-based models from optimistic, likely and pessimistic duration and cost estimates, connect task dependencies, and add probabilistic risks. The simulation engine samples thousands of outcomes and reports cost and schedule ranges, P50/P80/P90 results, loss and target-margin probabilities, deadline confidence, and the assumptions that drive variation. Users can test alternative scenarios on Business and Consultant licenses, calculate confidence-based quotes, export project data, and create printable decision reports. Project models stay in local browser storage; online license verification is required for the full workspace. Free standalone bid calculators are available without an account, while the multi-task simulation app requires a one-time license.

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.
