STACK
Cloud-based takeoff, estimating, and field collaboration for contractors.
About STACK
STACK is a cloud-based preconstruction and construction management platform covering takeoff, estimating, and field operations. Its Evaluate module auto-organizes and names plan pages and flags drawing revisions, while the Takeoff module provides AI-assisted digital measurement with auto-counting and scope suggestions. Estimating is worksheet-style with items, assemblies, and pricing analysis, and the Build mobile app handles plan markup, daily reports, RFIs, and punch lists on the jobsite. The platform is fully web-based with iOS, Android, and Windows apps, and connects to ERP systems and third-party tools including a STACK for Excel integration. It serves general contractors, specialty contractors, suppliers and distributors, and owners.
