Measure duct runs and count diffusers, dampers, and equipment from mechanical plans in zzTakeoff. Group HVAC quantities by system, floor, or bid package.

A simple three-step workflow to move from plans to estimate-ready quantities.
Build your HVAC takeoff from the mechanical plans, then check the schedules and details that define the scope. Keep measured lengths and counted items organized so your team can review the quantities before applying material and labor rates.

A mechanical plan shows where equipment belongs, while schedules describe what each item requires. Use separate count groups to review tagged units, accessories, and repeated layouts before handing quantities to the estimator responsible for pricing.

An addendum can move equipment, reroute ductwork, or change terminal counts across several sheets. Compare drawing revisions, revisit the affected measurements, and keep the revised scope organized for review with your estimating team.

Turn organized plan measurements into quantities your estimating team can review and price.
Use a simpler digital workflow to capture quantities, review scope, and keep your estimating process consistent.
Group ductwork, fittings, terminals, and equipment by system, floor, or equipment type. Your team can check coverage and follow the measurements before adding material, labor, and equipment rates.
Build takeoff groups around the way you bid HVAC work. Keep each quantity easy to find when a reviewer checks the drawings or asks how the estimate was developed.
Count tools plus duplicate and convert features handle the doors, fixtures, and typical layouts that repeat across a full plan set.
Instantly find every callout like "alternate" or "by owner" across a full drawing set instead of scanning sheet by sheet.
AI auto-naming, sheet numbering, and auto-scaling cut plan setup from hours to minutes, so you get more bids out the door and a better hit rate.
Estimators, PMs, and Precon Managers can work on the same project simultaneously. Split up a large plan set by trade or division and experience the power of teamwork.
Overlay and compare when an addendum moves walls or reworks the site plan, then adjust only the affected trades instead of starting over.
Check quantities from the jobsite, a pre-bid walk, or the office on your phone, tablet, Mac, or PC. No install, no VPN, no waiting to get back to your desk.
Import your existing PlanSwift and Bluebeam jobs, and bring your PlanSwift and OST templates with you, so you can hit the ground running instead of rebuilding your library from scratch.
★★★★★Great Tool for Excavation and Site Utilities“zzTakeoff has been a great tool for Kellenberger Inc., an excavation and site utilities company based in Northern Illinois. We use zzTakeoff on a daily basis to perform pre-construction takeoffs and assist with accurate cost proposals. We appreciate the ability to perform simple quantity takeoff reports but also build complex formulas to calculate material, removal of dirt spoils, stone import, and include labor production.”
Yes. Use zzTakeoff to measure areas and lengths and count items on digital plans. Organize duct runs, terminals, dampers, and equipment into takeoff groups so your team can review the quantities and develop material, labor, and equipment estimates.
Group your takeoff by system, floor, or zone as you measure. Keeping related quantities together makes it easier to check scope, review the drawings, and hand a clear quantity record to the team responsible for pricing.
Yes. Use your measured quantities with templates and assemblies to build material, labor, and equipment estimates. Apply the rates and assumptions appropriate to your project, then review the quantities and costs before submitting your bid.
Use the drawing overlay feature to compare a revised sheet with the previous issue. Review affected measurements and counts, check the related details, and update the changed scope while keeping the rest of your takeoff organized.
Yes. Create separate takeoff groups for base scope and alternates. Keeping those quantities distinct makes it easier to review an alternate, adjust the estimate when scope changes, and explain the quantity differences to your team.
Yes. zzTakeoff supports collaboration on the same project. Split the takeoff by system, floor, or zone, then review the measured quantities together so estimators can resolve scope questions before the bid is submitted.
Yes. zzTakeoff runs in a browser on a phone, tablet, Mac, or PC. Open the project to review the plans and quantities with your team from the office or jobsite, without installing desktop software.
Upload PDF, PNG, JPG, or TIFF files, including mechanical plans, details, and schedules. Measure directly on the drawings in your browser and keep quantities linked to the sheets they came from for easier review.
Yes. You can import existing PlanSwift and Bluebeam jobs and bring PlanSwift and OST templates into zzTakeoff. Review the imported project against your current drawings and estimating requirements before using it for a new bid.
