Mechanical estimating support
Duct Takeoff Services
Accurate ductwork quantities, fittings, accessories, insulation and labor information for mechanical contractors, sheet metal fabricators and suppliers bidding residential, commercial and industrial projects.
Clear quantities for confident ductwork bids
We review mechanical drawings, schedules, specifications and addenda to organize the scope into an estimator-ready workbook.
- Rectangular, round, spiral and oval duct
- Fittings, transitions and specialty connections
- Dampers, louvers, grilles, registers and diffusers
- Insulation, liner, sealants, hangers and accessories
- Labor hours, material pricing and scope notes
What we quantify
Detailed ductwork takeoffs built around your bid scope
Our duct takeoff services help mechanical teams understand material demand, fabrication requirements and installation effort before pricing or procurement. Quantities can be separated by floor, area, system, duct type or bid package.
Duct and fittings
Linear footage and surface area for rectangular, round, spiral and oval duct, including elbows, tees, reducers, offsets, transitions, taps and connections.
Air distribution
Grilles, registers, diffusers, louvers, plenums, flexible duct, boots, collars and related air-distribution components.
Dampers and accessories
Volume, fire, smoke, backdraft and combination dampers, access doors, turning vanes, screens, bird guards and specialty accessories.
Insulation and liner
External duct insulation, internal acoustic liner, vapor barriers, jacketing, sealants and insulation accessories measured by system and thickness.
Supports and installation
Hangers, trapezes, rods, angles, seismic supports and installation labor organized for practical bid review.
Equipment connections
Connections at AHUs, RTUs, exhaust fans, VAV boxes, fan coils and other scheduled mechanical equipment, subject to the project documents.

Our process
From mechanical plans to a bid-ready takeoff
1. Send the plans
Share mechanical drawings, specifications, addenda, bid form and any scope instructions.
2. Confirm the scope
We review the documents, identify coverage and provide pricing and turnaround.
3. Complete the takeoff
Our estimator measures ductwork, fittings and accessories and prepares marked drawings.
4. Review and revise
You receive editable files and can request clarifications or revisions through the bid date.

Frequently asked questions
Duct takeoff questions
What documents do you need for a duct takeoff?
Send the latest mechanical drawings, equipment schedules, specifications, addenda and bid instructions. If you have a preferred scope sheet or supplier format, include it with the plans.
Can quantities be separated by floor, area or system?
Yes. We can organize quantities by building, floor, zone, system, drawing area or another practical bid breakdown when the documents support it.
Do you provide both material and labor information?
Yes. Depending on the requested scope, the estimate can include material quantities, unit pricing, labor hours, labor costs and appropriate equipment or accessory allowances.
Are marked-up drawings included?
Our professional takeoff deliverables can include color-coded working drawings so measured quantities can be traced back to the plans and reviewed efficiently.
Can you update the takeoff when addenda are issued?
Yes. We support reasonable revisions and clarifications through the bid date. Send the revised documents and identify the changed sheets or addenda whenever possible.
