About
STACK is a comprehensive cloud-based construction management platform designed to help specialty contractors, general contractors, suppliers, and developers save time, increase accuracy, and improve team collaboration from bid decision through project closeout. The platform is divided into two major solution areas: Takeoff & Estimate, and Build & Operate. On the estimating side, STACK provides Plan & Spec Management tools to evaluate bid opportunities, search full plan sets, and compare plan versions. Its Quantity Takeoff module enables fast, accurate digital measurement of materials and labor, while the Estimates & Proposals feature leverages integrated items, assemblies, and regional pricing to help teams prepare competitive bids. For project execution, STACK's Build & Operate suite includes Document Control for accessing plans, documents, and as-builts from anywhere, Field Collaboration tools for sharing markups and assigning tasks, and a full Project Management module for issue tracking, progress reporting, and workflow customization. STACK also offers a dedicated mobile field app, enabling on-site teams to stay connected to the latest project documents and updates. The platform integrates with a wide range of third-party construction and business tools, making it easy to fit into existing workflows. It is used by estimators, project managers, superintendents, document controllers, and executives across the construction industry.
