STACK Construction Technologies
Cloud-based takeoff, estimating, and field-collaboration platform with AI-assisted measurement
Cloud construction software combining digital quantity takeoff and estimating (Takeoff & Estimate) with field collaboration, document control, and daily reporting for the build phase (Build & Operate). Floor Plan AI auto-detects doors, windows, rooms, and walls to generate a baseline takeoff, and STACK Assist is a chat-based AI assistant that answers plan-specific questions with sheet references. Founded 2008 as Cloud Takeoff; rebranded to STACK Construction Technologies.
Why This Tool Exists
Preconstruction estimators measure quantities off paper or PDF blueprints and build cost estimates in spreadsheets, a slow, error-prone process that is disconnected from the accounting/ERP and field tools used later in the project, and that makes it hard to catch missed scope before bidding.
STACK lets estimators measure directly from digital plans (area, linear, arc, pitched, count, volume) and turn quantities into priced estimates and bid-ready proposals in the cloud. Floor Plan AI auto-detects doors, windows, rooms, and interior/exterior walls to generate a starting takeoff that estimators edit rather than draw from scratch, and STACK Assist answers plan-specific questions (e.g., "where are the wall types defined?") with sheet-level references in about 30 seconds. A separate Build & Operate module carries plans, markups, punch lists, and daily reports into the field during construction, and the platform connects to Procore, QuickBooks, Sage Intacct, and Acumatica for accounting/ERP workflows.
