Darwin

Darwin is a construction cost estimation and cost-control platform designed to address one of the core problems in preconstruction: cost logic is repeatedly rebuilt, overwritten, or lost whenever designs, prices, or assumptions change. Darwin introduces a modular approach to estimating that treats cost logic as a reusable asset rather than a disposable output. At its core, Darwin separates estimation into independent but connected layers: quantities, cost logic, and market prices. Quantities can be derived from BIM models (IFC), measured from 2D PDFs, or entered manually. Cost logic is authored as reusable modules that define how materials, labor, equipment, and other cost components interact for a given company's own building methods. Market prices are applied through separate price lists, allowing estimates to be recalculated under different market conditions without altering the underlying logic, and delivered proposals remain on record unchanged even as prices are updated for re-costing. Darwin Workflow adds request management, price review, and formal approval tracking with revision history, while Darwin Cost Control tracks budget versus actual cost by cost group and module. Darwin Drive centralizes IFC models, drawings, quotes, contracts, and price lists alongside the estimate they support. AI in Darwin is used as an assistive tool — for module composition suggestions or draft proposal language — with all financial outputs calculated by the logic a company defines and reviewed by humans, not decided autonomously by AI. Each company operates in its own instance, and catalogues, pricing, and history are not shared across users or used for model training. Darwin is delivered as a cloud-based SaaS product available today in Individual, Team, and Enterprise plans, aimed at construction companies that price similar commercial or industrial work repeatedly.
