H2 Corporation
AI software that automates construction material takeoffs and estimating workflows to cut time, errors, and rework
About H2 Corporation
H2Corporation develops AI-driven software for the construction industry, focused on automating labor-intensive “takeoff” and estimating tasks from drawings and project documents. Its products are used by construction stakeholders such as general contractors and subcontractors to accelerate quantity surveying and related planning workflows, aiming to reduce manual work and improve consistency. The company’s flagship offering, AI Sekisan, applies computer vision and deep learning to recognize building components and route-based systems (e.g., pipes and ducts) from 2D plans and outputs materials summaries and related deliverables needed for quotations and estimation. H2Corporation has also expanded its product suite into adjacent workflows, including tools intended to streamline on-site surveying and downstream outputs such as tables and CAD-ready files. Operating in the broader construction-tech and construction productivity market, H2Corporation positions its software as a practical, workflow-embedded layer of automation for teams facing labor shortages, tight project timelines, and the high cost of estimating errors.
