Description

BidVariance is a web-based Monte Carlo estimation tool designed for consultants, agencies, engineering teams, and specialized contractors engaged in fixed-price projects. Users can create detailed task-oriented models by inputting optimistic, probable, and pessimistic estimates for both duration and costs, establishing connections between tasks, and incorporating probabilistic risks into their plans. The software's simulation engine performs thousands of outcome evaluations, providing insights on cost and scheduling variations, including P50, P80, and P90 results, as well as probabilities related to target margins, potential losses, and confidence in meeting deadlines, alongside the underlying assumptions that contribute to these variations. Additionally, users are able to explore alternative scenarios through Business and Consultant licenses, calculate quotes based on confidence levels, export their project information, and generate printable reports for decision-making. Project models are stored locally in the browser, but users must verify their online license to access the full suite of features. While free standalone bid calculators can be used without creating an account, the comprehensive multi-task simulation application requires a one-time license purchase for access. This combination of features makes BidVariance a versatile tool for effective project planning and risk assessment.

Description

PreConstruct AI is an online application designed for construction takeoff and estimating, catering specifically to subcontractors engaged in bidding for interior finishes, concrete, and wood framing projects based on PDF drawing sets. It efficiently interprets drawing scales and utilizes plan notes, schedules, and partition legends to assist in pinpointing and measuring quantities for walls, ceilings, and concrete. Currently in beta, the AI-driven wall suggestions are subject to review and modification by the estimator before final approval. Once quantities are sanctioned, they are transformed into detailed material lists that include items such as studs, boards, insulation, tape, compound, paint, concrete, and rebar, complete with calculations and references to the relevant drawing sheets. Estimators have the flexibility to input their own material prices, generate proposal PDFs, and export the data into Excel or CSV formats. Additionally, the application accommodates projects using imperial, metric, or mixed units. It also streamlines estimating workflows, allowing estimators to meticulously review measurements and quantities prior to bid submission, ensuring accuracy and completeness in their proposals. This functionality supports a broader range of project requirements, enhancing the overall efficiency of the estimating process.
