Demotik, a super-subcontractor based out of Cypress, Texas, achieved 50-75% better productivity with STACK!
STACK's central hub for all the essential tools, insights and information you need to get started.
As the construction industry continues to evolve, so does the technology that powers faster, more accurate, and more collaborative project workflows. This year, STACK delivered some of our most impactful innovations yet—features designed to streamline estimating, strengthen field-to-office communication, eliminate redundant work, and unlock the full potential of your project data.
From AI-driven enhancements to powerful new integrations and workflow improvements, each update reflects our commitment to helping teams build smarter and more efficiently. Below, we’re excited to highlight the top features of the year and how they’re transforming the way construction professionals work.
You can enter Measured Quantities directly in your Estimate Worksheet without using the takeoff tools to actually measure anything in STACK.
Just add/create takeoffs in the project, then manually enter the Measured Quantity (Primary measurement) as well as any Secondary measurements for the takeoffs in the estimate.
The values you enter will be used as the inputs to any item coverage/productivity rates and item formulas in assemblies, so you can continue to use your existing items and assemblies (which use those formulas to convert the Measured Quantities into Purchase Quantities).
When you have an item that is associated with multiple Takeoffs, Plan Sheets, Assemblies, Item Groups, Tags, and/or Labels, you can Roll Up all the associated data so it is displayed as a single line item on your Estimate Worksheet or roll out the data so each association is displayed as an individual line item. (Roll Up is the default when you create an Estimate Worksheet.)
When you Roll Up the data, the associated line item cells are either summed (Measured Quantity and Extended Cost) or copied (Unit Cost and Waste %).
