One TCLP result can multiply your biggest cost line
You priced the dirt as non-hazardous off borings somebody else drilled, and the TCLP came back failing for lead.
A steel or copper escalation is in an index the owner can pull up, so that conversation is short. This one is a chemistry result on material that was never fully characterized before bid, and the change order routes through the owner's own consultant, who wrote the boring plan that missed it. No other trade has its largest cost line reclassified by a laboratory after the contract is signed.
The size of it
On a 3,000 ton job that swing is roughly $150,000 to over $1M of exposure tied to a line you priced from someone else's borings.
A single lab result decides whether the biggest number in the bid is fifty dollars a ton or four hundred and fifty, and it comes back after the price is fixed. Soil bid as non-hazardous goes to a Subtitle D landfill somewhere in the $25 to $75 per ton range. A TCLP failure, usually benzene or lead out of old leaded gasoline, reclassifies that same dirt as Subtitle C hazardous at roughly $140 to $450 per ton, plus manifested transport and possibly stabilization before anyone will take it. Disposal and haul is frequently the single largest cost line in the whole bid, and it gets priced off a limited boring grid you didn't drill.
Three moves, in order
Step 04: Estimating system
The estimate maps one to one onto the job cost codes, so variance means something the day it appears.

What environmental remediation owners ask
Soil failed TCLP after bid who pays for hazardous disposal?
You priced the dirt as non-hazardous off borings somebody else drilled, and the TCLP came back failing for lead.
What does it cost?
On a 3,000 ton job that swing is roughly $150,000 to over $1M of exposure tied to a line you priced from someone else's borings.
What do I do first?
Bid the tonnage at the non-hazardous unit price and price a separate published unit rate for Subtitle C tons, manifested transport, and stabilization, so a reclassification becomes arithmetic and not a negotiation.
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 04, estimating system. The estimate maps one to one onto the job cost codes, so variance means something the day it appears. It comes from chapter 4 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.
