CostOS
Construction estimating software with AI quantity takeoff, benchmarking database, and parametric cost modeling.
What it does
CostOS (by Nomitech) is a construction cost estimating platform used by civil engineers, quantity surveyors, and construction estimators for infrastructure projects - covering quantity takeoff from 2D drawings and BIM models, unit rate databases, parametric cost modeling, and benchmark cost analytics. AI capabilities include AI-assisted quantity takeoff that identifies and measures elements from drawing sets, intelligent unit rate suggestions based on project type, location, and historical data from the CostOS database, parametric estimating that generates preliminary cost estimates from high-level project parameters before detailed design is available, and benchmark analytics that compare project costs against similar historical projects. CostOS is widely used for infrastructure, civil, and public sector construction estimating.
Why AI-ENHANCED
CostOS is an established construction estimating platform that has integrated AI-assisted takeoff, intelligent unit rate recommendations, and parametric cost modeling into a mature infrastructure cost estimating product.
Best for
Small civil engineering firms and quantity surveying practices use CostOS for professional infrastructure cost estimating - AI-assisted takeoff and rate databases producing accurate estimates faster than manual methods.
Mid-market construction companies and infrastructure consultancies use CostOS for systematic project cost management - parametric estimating for early-stage projects and detailed takeoff for final estimates with benchmark analytics validating accuracy.
Large engineering consultancies and public sector infrastructure agencies use CostOS for enterprise estimating - benchmark analytics across historical project portfolios informing cost planning and AI-assisted takeoff scaling estimating capacity.
Limitations
CostOS is optimized for civil, infrastructure, and public sector estimating — residential and commercial building estimators find tools like Buildxact or ProEst better suited to their project types.
CostOS's parametric estimating capabilities are powerful but require investment in learning the modeling approach — estimators accustomed to traditional takeoff methods face a methodology change alongside software adoption.
CostOS's benchmark rate database is most useful when populated with local and project-specific historical rates — organizations starting with the database from scratch see less AI suggestion accuracy until sufficient data is built up.
