Our Duct Takeoff Service provides a complete and highly accurate breakdown of all ductwork materials required for HVAC systems in residential, commercial, and industrial buildings. Every duct, fitting, transition, and accessory is measured with precision using advanced digital estimating software, ensuring you receive quantities you can trust for bidding and construction planning. Whether the project involves rooftop units, air handling systems, VRF, or large mechanical plant rooms, our takeoffs are designed to give contractors a clear understanding of sheet metal requirements, installation complexity, and coordination needs across the building.
We begin by analyzing mechanical plans, riser diagrams, schedules, and specifications to capture every duct run accurately. Each system is measured separately so you receive a clean and organized breakdown for supply, return, outside air, relief, and exhaust. Duct sizes are taken exactly as shown on plans with clear separation of pressure classes, gauge requirements, insulation types, and duct construction standards.
Rectangular duct is measured with straight lengths, offsets, elbows, tee branches, transitions, end caps, takeoffs, and splitter fittings included. Spiral and round ducts are measured with all associated fittings such as 45 and 90 degree elbows, reducers, saddle taps, and collars. Flex duct is also measured by length and diameter with clear identification of its use per zone or branch.
We study equipment connections, diffuser layouts, and mechanical room configurations to ensure all transitions, duct drops, and connections are accounted for. If VAV boxes or fan powered units are included, we measure inlet and outlet ducts carefully so the final quantities match actual field installation.
You receive a fully structured estimate that includes:
Your mechanical contractor, estimator, or project manager can directly use this report for bidding and planning without rework
