Quantity Takeoff

Real measured quantities beat a rough guess, every time

My Project Estimating  ·  Quantity Takeoff

Two estimators can look at the same drawings and come back with two different numbers. One of them measured the job. The other one had a feel for it, based on the last few jobs that looked roughly similar. Only one of those numbers is actually built on the job in front of you.

That's the whole argument, really. An estimate's only as good as where its quantities came from.

A guess is still a guess, however confident it sounds

A confident estimator can make a rough number sound certain. But confidence isn't the same as accuracy, and a quantity that was scaled up from memory doesn't become more reliable because it was delivered without hesitation. If nobody measured the substructure off the drawings, nobody actually knows how much concrete the job needs. They know how much a similar job needed, which isn't the same thing.

What measuring off the drawings actually changes

When quantities are taken off the drawings element by element, to NRM2, the number in front of you reflects this job, not a job that looked a bit like it. Groundworks, superstructure, finishes, external works, each measured against what's actually shown, not against what usually gets used on a build this size. That's the difference between an estimate and an educated guess wearing an estimate's clothes.

Why this matters more than which software did the sums

There's a lot made of tools and spreadsheets in this trade, but none of it fixes a quantity that was wrong to begin with. 25+ years contractor-side is enough to know that the number's only as good as the measuring behind it. Get the quantities right and the rest is arithmetic. Get them wrong and no amount of polish on the final document saves you.

We measure every job off your drawings, to NRM2, so the quantities you're pricing from are the job's actual quantities, not a rough idea of them. Send your drawings and we'll measure it properly before you commit to a number. See a sample estimate to see exactly what a measured breakdown looks like next to a guess.
