Ladder provides an AI-powered preconstruction platform that enables contractors, engineers, and public infrastructure owners to generate accurate cost estimates and assess project risks before bidding. Trained on thousands of completed public works projects and real-time market data—including material costs, labor rates, and regional multipliers—the platform identifies scope gaps, cost fluctuations, and potential change order risks. Ladder's features include automated quantity takeoffs, built-in risk analysis, bid benchmarking, and scenario testing, allowing users to evaluate design alternatives and value engineering options. By replacing manual estimation processes with data-driven insights, Ladder helps stakeholders improve bid accuracy, reduce cost overruns, and make informed decisions throughout the project lifecycle.
