The three words people mix up
Takeoff, estimate, and bid are related. They are not the same.
Takeoff
Takeoff is measurement. You open the PDF, set the scale, and record what is on the drawing: linear feet of main, square feet of restoration, each hydrant. If this step is sloppy, every price after it is a guess with extra decimal places.
Estimate
The estimate is what the work costs you. Labor, equipment, material, production, duration. A 2,106.36 LF water main at 200 LF/day is 10.53 calculated workdays in the Cedar Ridge sample. That is a production picture, not a bid. Rates in the demo are illustrative.
Bid
The bid is what you offer to do the work for. It starts from the estimate, then you add markup, strategy, and the risk you are willing to take. Two estimators can share a takeoff and still submit different bids. That is the job.
Calling the whole loop "bidding software" hides the part that actually goes wrong: a quantity that cannot be walked back to the plan, or a price that forgot how the crew is supposed to build it.
Why they belong in one workspace
Follow the bid back to the plan.
On Mac, Construction Takeoff links bid items to their source measurements. Select an item, choose Show takeoffs, and the geometry that supports the quantity comes into focus. If the owner schedule says 2,100 LF and the measured takeoff says 2,106.36 LF, you can compare both at the same unit price and then check the source of the difference.
That is the workflow Mason wanted after about 10 years in construction and 5 years estimating and project managing. Estimating software innovated about 20 years ago, then most of the industry kept exporting quantities into a file that no longer knew where they came from.
AI fits in the first stage. A compatible assistant can prepare the takeoff. You still build the estimate and decide the bid. Read how AI estimating stays reviewable.
What is available today
Mac for the full loop. Browser for the first takeoff.
Construction Takeoff on Mac is where the connected estimate lives today: unit pricing, production, workdays, owner-quantity comparison, and source tracing. Get it from the App Store.
Takeoff Bid Cloud is the early-access browser workspace for PDF takeoffs, private projects, and AI-assisted measurement review. It is $20/month by invitation. The sample is free. Individual accounts are available now; team workspaces are still in development. Some desktop workflows are not in the browser yet.
The long-term target is the same takeoff-to-estimate loop in the browser that the Mac app already runs. No launch date attached. The work is to keep the loop honest.
Questions estimators ask
A few useful details
Is estimating the same as bidding?
No. The estimate is what the work costs you: labor, equipment, material, and production. The bid is what you offer to do it for, after markup and strategy.
What is a takeoff?
A takeoff measures the plan. You calibrate the scale and record lengths, areas, and counts so later pricing has a quantity that can be traced back to the drawing.
Can I compare owner quantities with my takeoff?
Yes, in Construction Takeoff on Mac. Compare the owner schedule with measured takeoff at the same unit prices, then follow a difference back to the source geometry.
Does the browser version include the full estimate yet?
The browser is early access for PDF takeoffs, saved projects, and AI measurement review. The fuller connected estimate, including production and source tracing, is in the Mac app today.
