GRADING · CIVIL AND EARTHWORK · FIXED BY STEP 08

When The Vertical Trades Slip, Your Silt Fence Pays

You installed the BMPs in week one and got paid for them once. The seven day inspection clock keeps running until the site stops being a construction site.

WHY IT IS A GRADING PROBLEM

Most subcontract scopes close out when the work is installed and accepted. This one is a recurring service tied to a permit and held open by a schedule other trades control. Your people keep walking a site where your production work finished a year ago. Nothing about that walk is in the billing schedule.

WHAT IT COSTS

The size of it

A 26 week overrun is 26 unbilled site visits, plus replacement silt fence, inlet protection, and construction entrance rock after every qualifying storm. All of it charges to a cost code that spent its budget in month one.

Erosion control is a day one install carrying an obligation that runs the full active construction period, however long that turns out to be. The EPA Construction General Permit requires an inspection at least every 7 calendar days, plus one within 24 hours of any storm producing 0.25 inches or more. Whoever installs the BMPs generally owns the inspection and repair duty, and on a sitework package that's you. You priced those weeks against the schedule you were shown at bid. When the building runs six months long, your inspection weeks run six months long with it, and no standard subcontract pays a sub for extension weeks of erosion control maintenance.

WHAT TO DO

Three moves, in order

STEP 01
Log every permit inspection with date, storm trigger, and repair performed in one place, and total the hours at the end of each month.
STEP 02
State the schedule you priced on the proposal and publish a weekly rate for inspection and BMP maintenance beyond it.
STEP 03
Flag any job that passes its original completion date and send the extension weeks as a change order that same month, while the log is still fresh.
QUESTIONS

What grading owners ask

Can i bill for swppp inspections after the job runs long?

What does it cost?

What do I do first?

Log every permit inspection with date, storm trigger, and repair performed in one place, and total the hours at the end of each month.

What are grading contractors supposed to be making?

Grading runs 18% gross margin, 16% overhead and 2% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 5 points below it. The CFOS target is 10%.

Which part of the system fixes it?

The step is number 08, standards and accountability. Five hours a month of owner time, spent ahead of the work. It comes from chapter 8 of CONTROL: The Construction Financial Operating System.
