Attentive.ai (Beam AI)
AI-powered construction takeoff and estimating software for GCs, subcontractors, and suppliers
AI takeoff platform that reads PDF construction drawings (architectural, structural, civil, and MEP sheets) and extracts trade-specific quantities across 15+ trades, including HVAC, electrical, plumbing, concrete, steel, paving, and landscaping. Offered as a self-service mode (claimed ~10-minute turnaround, 90% feature-capture accuracy) or a QA-reviewed "done-for-you" service (24-72 hour turnaround, claimed accuracy within ±1% of in-house takeoffs). Operated by Attentive.ai, which also sells a separate per-property takeoff product for landscaping/paving/snow field services (formerly branded Automeasure) and has recently launched a BIM CoPilot modeling service.
Why This Tool Exists
Estimators at general contractors, subcontractors, and material suppliers manually take off quantities (linear footage, area, counts) from PDF construction drawings across multiple trades — a process that can take hours per bid, limits how many jobs a team can pursue in parallel, and creates risk of costly quantity errors.
Beam AI, Attentive.ai's flagship product, uses computer vision to scan uploaded PDF drawings — architectural, structural, civil, and MEP sheets — and automatically extract per-trade quantities (ductwork, piping, fixtures, rebar, paving surface, and similar features), exporting results to Excel or PDF. Customers choose a self-service mode that returns a takeoff in about 10 minutes, or a "done-for-you" mode where Attentive.ai's QA team reviews the AI output before delivering it within 24-72 hours.
