What Actually Goes Into Pricing a Job Before It Goes Out the Door

My Project Estimating  ·  Construction Estimating

Reading the drawings before you touch a number

Every estimate starts the same way: someone has to actually read the drawings and the specification properly before a single rate goes on the page. Skim it and you miss the item that costs you at the end. A proper take-off means going through every drawing, cross checking the specification against what is actually shown, and flagging anything unclear before you price it rather than guessing and hoping it works out.

Pick the right method for the stage you are at

Not every price needs the same level of detail. Early on, a top down figure based on similar jobs you have priced before is fine for giving a client a ballpark. Once drawings firm up, you need a bottom up build up, item by item, with your own labour constants and current material rates. Mixing the two up, treating a rough early figure as a firm tender price, is how contractors end up carrying costs nobody agreed to.

Get out on site before you commit to a number

Nothing in a set of drawings tells you about access, ground conditions, parking restrictions or what the neighbouring property is like. A site visit before pricing catches the things that turn a straightforward job into a difficult one. Skip it and those costs surface after you have already submitted a price you cannot walk back from.

Build in a contingency, not a guess

Every job has unknowns, existing services that are not where the drawings say, prices that move between pricing and starting on site, variations that come in after you are committed. A sensible contingency, priced properly rather than plucked from the air, protects your margin without pricing yourself out of the job.

Get a second pair of eyes on it

The person who built the estimate is the worst person to check it. They know what they meant to include, which is exactly why they miss what they left out. A second person going through the take-off, the rates and the arithmetic before it goes out catches the errors that cost real money later.

If you would rather hand the take-off and pricing to someone who does this daily, Send your drawings and specification over and we will build the estimate properly. See a sample estimate first to check the level of detail before you commit.
