What estimating taught me about everything else

An estimate is a promise with a number attached. Get it wrong in one direction and you lose the job; get it wrong in the other and you win the job and lose money. The whole craft lives in a narrow band between those two mistakes.

The drawings never lie, but they do mumble

Most of estimating is reading — drawings, specs, addenda, soil reports. The information is almost always there. It’s just never where you’d like it to be, and it never announces itself. The skill isn’t math. The skill is noticing.

That turned out to be transferable. A parking lot tells you where the problems are if you walk it slowly. A hat sample tells you whether the factory cut corners if you turn it inside out. Everything mumbles. You learn to listen.

Contingency is honesty

People think contingency is padding. It’s the opposite — it’s the most honest line in the estimate. It’s the number that says “here is exactly how much I don’t know.”

I started putting contingency lines on everything in my life. Time to leave for the airport. Budget for the hat launch. Patience for the guy parked across two spots. Works every time.

The bid is due when the bid is due

Construction gave me the healthiest relationship with deadlines I’ve ever had. Bid day doesn’t move. You can be 95% sure and on time, or 100% sure and irrelevant.

Ship the hat. Send the invoice. Publish the article. The bid is due when the bid is due.
