Why budgets blow up

Overruns are rarely bad luck.

Most overruns aren't bad luck. They're built into the project before the first shovel hits the dirt. Walk the six stages below and you'll see exactly where the money goes, and what it takes to stop it.

The build journey

Six stages. Six places the budget quietly moves.

Tap a stage to see where money leaks and what I do about it.

Design

What gets drawn decides what gets built.

Where money leaks here

Incomplete drawings turn into change orders (a price change for work added or changed after you sign) later.

What I do about it

I review the plans for gaps before they go to bid.

Common causes

The six things I see most often.

Low allowances

The bid looked cheap because the numbers underneath it were soft. An allowance is a placeholder budget for things you haven't picked yet, and it gets corrected upward later.

Incomplete drawings

Every gap in the plans turns into a change order once the framer is standing there asking what to do.

Unchecked change orders

Someone has to read the price, the scope, and the schedule impact. On most projects nobody does.

Ground and foundation surprises

Coastal lots bring surprises underground. Ground and foundation problems, hillside support, and drainage are where quiet money disappears, and all of it can be tested before you buy, not after.

Permitting and schedule slip

Every month of delay costs you interest, rent, and insurance, what I call carrying costs. The schedule is a budget line, not just a calendar.

Small additions add up

Small additions feel free one at a time. Together they move the budget by millions over a two-year build.

What building actually feels like

It isn't only the money that gets heavy.

  • Hundreds of decisions, most of them made under time pressure.
  • Being the only non-expert at the table.
  • No way to tell whether a $40,000 change order is fair.
  • Time away from work and family.
