An open hole is rented equipment with no production
The cut is finished, the sidewalls are trimmed, and your crew and your machines wait there while a lab decides whether you're allowed to backfill.
Every other trade on the site is waiting on you, and you're waiting on a laboratory. Weather and sequencing are arguments you can take to the OAC meeting, while a pending confirmation result has no committed return date and no one to escalate to. Machines on a remediation hole also can't be shuffled to another job easily, because pulling decon'd equipment out of an exclusion zone costs more than leaving it parked.
The size of it
Idle crew and rented equipment wait on a job that bills by the ton, and the second and third mobilization get absorbed as overhead unless the contract includes a standby clause and a per mobilization unit price.
Remediation goes first on a site and comes back repeatedly, and the trade can't close its own work. The consultant pulls floor and sidewall confirmation samples, the lab tests them, and one sidewall exceedance means another cut and another round of sampling. While that plays out you're holding HAZWOPER qualified labor, exclusion zone setup, air monitoring, decon, and consumables, all of which cost money per mobilization. Find a hot spot mid dig and you demobilize and come back, which the lump sum line item paid for one time.
Three moves, in order
Step 02: Equipment cost basis
A correct internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it.

How to charge standby waiting on confirmation samples before backfill?
The cut is finished, the sidewalls are trimmed, and your crew and your machines wait there while a lab decides whether you're allowed to backfill.
What does it cost?
Idle crew and rented equipment wait on a job that bills by the ton, and the second and third mobilization get absorbed as overhead unless the contract includes a standby clause and a per mobilization unit price.
What do I do first?
Build an hourly and daily standby rate for every piece on the site, excavator, plates, shoring, dewatering pump, and air monitoring gear, off your own ownership and rental cost, and attach it to the contract as an exhibit.
What are environmental remediation contractors supposed to be making?
Environmental remediation has 23% gross margin, 16% overhead and 7% net profit after taxes at $1M to $5M. The all-trade average is 7%, so this trade is right on it. The CFOS target is 10.5%.
Which part of the system fixes it?
The step is number 02, equipment cost basis. A correct internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it. It comes from chapter 2 of CONTROL: C.F.O.S. Construction Financial Operating System.
Everything on this page is something you can install yourself, and CONTROL is the order to do it in. If you would rather buy the finished result, SPM The Construction CFO does this work for environmental remediation contractors as a service. It is a separate firm, Sulphur Prairie Management, LLC, led by the same author.
