Firm offers AI-powered takeoff and estimating software built for mechanical and HVAC preconstruction.

SMACNA is proud to announce Rebar as a new Gold Associate Member!
Rebar is AI-powered takeoff and estimating software built for mechanical and HVAC preconstruction. Upload a PDF drawing set and Rebar identifies equipment, counts, measures, and parses schedules then hands it to your estimator to review and adjust. Contractors bid more work without adding headcount. Priced per takeoff, unlimited users.
Rebar offers AI-powered takeoff and estimating software for mechanical and HVAC preconstruction turning a PDF drawing set into a structured, reviewable takeoff in minutes instead of days, which may be useful to many SMACNA members.
Chris Lagana, Value Engineer talked about becoming a SMACNA Associate Member, “We are simply excited to meet the membership and start better understanding their needs and how we can meet them!” He continued, “Rebar's AI Takeoff, AI Ductwork, and Bid Board modules read the drawing set and schedules so the estimator can spend their hours reviewing and pricing, not clicking. We're excited to make it available to SMACNA's membership.”
