Material cost, shop labor, and field labor for ductwork are all driven by linear feet, fitting counts, and total pounds. If the takeoff is short, the bid is short. A precise duct takeoff gives your HVAC estimation a foundation you can trust.
A single fitting can take longer to fabricate and install than several feet of straight duct. Takeoffs that lump fittings into linear footage understate labor and leave contractors working for free. Counting fittings separately reflects how sheet metal work really happens.
When duct quantities are organized by system, size, and gauge, shops can plan coil usage, nesting, and production schedules with confidence. Purchasing teams order the right amount of sheet metal, insulation, and accessories. For other trades and full project counts, explore our quantity takeoff services.
We measure rectangular duct by width, height, and length for supply, return, exhaust, and outside air systems. Each run is assigned a gauge, joint type, and reinforcement based on its size and pressure class. Contractors get exact square footage and weight for every section.
We take off round and spiral duct by diameter and length, including exposed spiral systems in open ceilings. Fittings such as couplings, reducers, and branch connections are counted separately. Shops and installers get quantities that match how spiral duct is ordered.
We measure flat oval duct and fittings where ceiling space is limited and large air volumes are required. Major and minor dimensions are recorded accurately for fabrication. This specialty duct is priced correctly instead of treated like round or rectangular.
We count elbows, tees, wyes, offsets, transitions, end caps, and branch takeoffs by size and type. Radius and mitered elbows are separated, along with turning vane requirements. Fitting counts give a true picture of fabrication and installation labor.
We calculate total sheet metal weight by gauge, material type, and pressure class using SMACNA guidelines. Galvanized, aluminum, stainless steel, and black iron are listed separately. Contractors know exactly how much material to buy and price.
We measure flexible duct runouts to diffusers and terminal units by diameter and length. Insulated and uninsulated flex are separated, along with clamps and connections. Small runout quantities add up quickly across large floors.
We count fire dampers, smoke dampers, volume dampers, backdraft dampers, access doors, flexible connectors, and turning vanes. Each accessory is tied to its size and location. These items are frequently missed and can significantly affect cost.
We count supply diffusers, return grilles, exhaust registers, linear slot diffusers, and VAV boxes from plans and schedules. Each device is listed by size, type, and neck connection. Contractors get complete counts for ordering and installation.
We calculate duct wrap and internal liner by square footage, thickness, and material according to the specifications. Exterior duct, plenum, and exposed sections are identified separately. Insulation contractors and mechanical contractors get ready to use quantities.
We estimate trapeze hangers, strap hangers, rod, anchors, and sealant based on duct size and spacing requirements. Seismic bracing can be included where required by code. These overlooked materials are captured before they become field surprises.
We take off welded black iron grease duct, stainless steel exhaust, laboratory fume exhaust, and dishwasher exhaust systems. Fire rated wraps and cleanouts are included where required. Specialty systems are measured with the detail their higher cost demands.
When drawings are revised, we compare the new set with the original and measure only the added, deleted, or modified ductwork. Changes are clouded and quantified clearly. Contractors get solid backup for pricing duct changes.
Ductwork changes greatly from one building type to the next, from simple residential runs to stainless steel lab exhaust. We measure each system with the standards and materials its facility requires.
Sheet metal contractors use our takeoffs to bid more projects and plan shop production.
Mechanical contractors rely on our duct quantities as the foundation for complete HVAC bids.
Fabrication shops use our organized quantities to schedule production and order coil stock.
Insulation companies rely on our duct wrap and liner quantities for accurate bidding.
GCs use our takeoffs to verify sheet metal scope in mechanical subcontractor bids.
Suppliers use our counts of duct, fittings, and accessories to prepare material quotes for contractors.
Getting accurate duct quantities is simple and fast. Here is how we turn your mechanical drawings into organized sheet metal takeoffs.
Upload HVAC plans, details, schedules, and specifications, along with any preferred takeoff format or pressure class requirements.
We review the duct systems included, confirm exclusions, and send a fixed fee with delivery time.
We take off duct, fittings, accessories, and hangers, then a second specialist checks sizes, gauges, and counts.
You receive quantities in Excel with marked up plans, organized by system, floor, size, and gauge.
Browse real samples of our takeoffs, cost estimates, and drafting work to see the level of detail you can expect on your own project.
Pricing depends on building size, number of sheets, duct systems included, and complexity. A small office tenant space costs much less than a hospital with multiple air handlers and specialty exhaust. We send a fixed fee after reviewing your drawings.
Small and medium projects are usually delivered within one to three business days. Large commercial or healthcare projects may take three to five business days. We confirm the delivery time with your quote.
We calculate duct surface area, assign the correct gauge based on duct size and pressure class under SMACNA standards, and convert the area into weight. Seams, joints, and reinforcement allowances are included. Weight is reported by material type and gauge.
Yes. Every elbow, tee, transition, offset, and branch takeoff is counted individually by size and type. This gives a more accurate picture of fabrication and installation labor than lumping fittings into straight duct footage.
Our duct takeoff service provides detailed quantities. If you need full material and labor pricing for the entire HVAC scope, our HVAC estimation team can build the complete estimate from the same takeoff.
Yes. We measure duct wrap and internal liner by square footage, thickness, and material type based on project specifications. Exterior and exposed duct sections are listed separately.
Yes. We take off double wall duct, stainless steel, aluminum, PVC coated, and welded black iron systems. Specialty materials are separated so they can be priced correctly.
Takeoffs are organized by system, floor, area, duct type, size, and gauge. We can also follow your company’s preferred format, whether for bidding, purchasing, or fabrication.
Yes. We extract duct quantities from Revit and fabrication models, then verify them against the 2D drawings to catch missing or incorrectly modeled elements.
Yes. We estimate hangers, rods, anchors, and supports based on duct size and spacing requirements. Seismic bracing is included where codes or specifications require it.
Yes. We measure welded grease duct, stainless steel exhaust, laboratory fume exhaust, and other specialty systems, including fire rated wraps and cleanouts where required.
Every takeoff is reviewed by a second specialist who verifies duct sizes, gauges, fitting counts, and totals against the drawings. Marked up plans show exactly what was measured, so your team can review and confirm every quantity.
