About

STACK is a cloud-based construction technology platform designed to streamline preconstruction and project workflows for contractors, subcontractors, suppliers, and developers. It offers fast and accurate quantity takeoffs, cost estimating, and professional proposal generation, all accessible through a simple web interface. With STACK, users can upload plans, perform digital measurements, add markups, and collaborate with team members in real time. The software reduces reliance on manual estimating, helping companies save significant time and increase accuracy.STACK also provides robust document management, enabling teams to maintain a centralized hub for blueprints, specifications, and revisions. Its cloud-based structure ensures accessibility from any device—PC, Mac, or mobile—without the need for downloads. For field operations, the mobile app allows users to view, annotate, and update plans directly on-site, ensuring seamless communication between office and field teams.Since its founding in 2011, STACK has grown into one of the most widely used platforms for digital takeoff and estimating. Its combination of automation, collaboration, and reporting tools makes it a complete solution that improves bid speed, accuracy, and overall project management efficiency for construction professionals.

STACK Construction Technologies provides a comprehensive suite of tools that help construction professionals manage projects from the planning stage through completion. Its flagship feature is the digital takeoff capability, which allows users to quickly measure areas, lengths, volumes, and item counts directly from uploaded blueprints. Automation tools such as template libraries, grouping, auto-count, and hyperlinking make this process significantly faster and more accurate compared to manual methods.

The estimating module enables detailed cost breakdowns by incorporating labor, materials, overhead, markup, and taxes. Users can generate polished, branded proposals with alternate options for clients, while exporting data in flexible formats like Excel for further analysis. This makes bid preparation more efficient and ensures a professional presentation of project costs.

Document management is another critical element of STACK. It allows users to centralize all plans and specifications, search through documents with full-text capabilities, and manage revisions with version overlays and automatic naming. This ensures accuracy and prevents confusion when multiple revisions are being handled.

For construction execution, STACK provides mobile-friendly tools that allow field teams to access, annotate, and collaborate on project documents in real time. Offline functionality ensures continuous access even without internet connectivity. The platform also supports workflows for project tracking, plan sharing, and as-built documentation.

STACK is cloud-native, requiring no installation and allowing seamless updates and accessibility from anywhere. Its emphasis on collaboration, automation, and real-time project visibility helps companies improve productivity and reduce errors. With strong customer support, training resources, and scalable subscription plans, STACK serves businesses of all sizes, from small subcontractors to large general contractors.

Overall, STACK empowers construction teams to deliver faster, more accurate bids, streamline workflows, and maintain tighter control over projects, ensuring higher profitability and efficiency.
