What a quantity takeoff actually is, and why every number in your bid comes from it

Ask five contractors what a takeoff is and you'll get five different answers, most of them close enough, but nobody quite says it in one sentence. So here it is plainly: a takeoff is the measured list of everything in the job, taken off the drawings, item by item, before a single price gets put against it.

Concrete volumes. Blockwork by the square metre. Linear metres of drainage. Doors, windows, first fix, second fix, external works, the lot. Measured, not guessed.

Why it's the base of every number you bid

Your estimate is only as good as the quantities underneath it. If the takeoff says 40 square metres of blockwork when the drawing actually shows 55, your price is wrong before you've even applied a rate to it. Get the quantities right and the rest of the pricing follows. Get them wrong and no amount of careful rate setting saves the bid.

That's why a rushed takeoff, done at speed the night before a bid's due, tends to cost more than the time it saved. A missed run of first fix or an underused quantity doesn't show up until the job's on site and the material order comes in short.

How we do it

We measure the job off your drawings to NRM2, so every element is accounted for in a consistent, recognised way, not a rough guess dressed up as a number. You send the drawings you've got, plans or sketches, and we take off every element and price it on current UK rates. You get the full priced estimate back before your bid is due, built from quantities that were actually measured rather than estimated by eye.

Why it matters even on smaller jobs

It's tempting to skip a proper takeoff on a smaller job and price it by feel instead. That's fine when the feel is right. It's expensive when it isn't, and there's no way to tell which one you've got until the job's running and the numbers don't add up.

A takeoff isn't a formality that sits between the drawings and the bid. It's the thing that makes the bid correct in the first place.

Send your drawings and get the quantities measured properly, so the number you bid is the number the job actually needs.
