Civils.ai is an AI-powered platform designed for construction teams to automate quantity takeoffs, earthworks and subsurface data extraction, and contract/spec checks from PDF drawings and documents. It helps estimators, geotechnical engineers, and pre-construction teams reduce manual effort with AI workflows that measure areas, lengths, volumes, and counts directly from drawings. The platform also extracts subsurface data from geotechnical reports, including borehole logs, and allows users to run AI-assisted checks across drawings, specifications, and codes of practice. Results are reviewed by a quality assurance team to ensure accuracy, and can be exported to Excel and annotated PDF. Trusted by over 200 firms, including AECOM and Arup, Civils.ai reduces manual takeoff effort by up to 90% with 97% accuracy.
