The Job on Every Tender Nobody Has Time to Do Properly

My Project Estimating  ·  Construction Estimating

Every contractor ends up doing estimating at some point, usually late at night, usually squeezed between running current jobs and looking at a new set of drawings that just landed. It's a specific skill, and doing it badly costs you more than doing it slowly.

It's not just adding up quantities

A cost estimate worth pricing off pulls together the drawings, the specification, current material and labour rates, and a realistic read of the site, then turns all of that into numbers you can stand behind. Miss the specification detail and your quantities are wrong before you've priced a single line.

The measuring is where most errors start

Get a quantity wrong on a drawing and every rate you apply afterwards compounds that error. This is why a proper take-off, broken down against NRM2, matters more than the software used to produce it. The structure is what stops errors hiding in a big total.

It runs the whole length of the job, not just the tender

A decent estimate isn't a one-off document you produce and forget. It should hold up when the job's running, when a variation lands, when someone on site asks why an item costs what it costs. If your original figures were rushed, you'll be defending guesswork months later instead of a proper measured position.

Contractors who separate this work price better

The contractors who win consistently tend to separate the estimating from the site running, not because they can't do it themselves, but because doing both at once means one of them suffers. Handing the measuring to someone dedicated to it frees you up to run the job you've already got and price the next one properly.

We measure quantities from your drawings and specification and price them against current UK rates, broken down to NRM2, so you've got a figure you can defend at tender and on site. Send your drawings and we'll take the measuring off your plate, or see a sample estimate to see the level of detail you'll get back.
