STACK is purpose-built for construction, spanning Evaluate, Takeoff, Estimate and Build. Its stated audiences are specialty contractors, general contractors, suppliers and manufacturers, and owners/developers, with trade-specific coverage for concrete and masonry, drywall, electrical, framing, insulation, mechanical and painting. Core value is doing takeoff and estimates faster and more accurately so contractors bid more work, then carrying the same scope and budgets into the field for RFIs, daily reports, photos and markups without rekeying.
