Grade wasn't ready and the day is still paid for
The plant slot gets bought days ahead, along with eight to twelve trucks and a full crew. When the grade isn't ready at six in the morning, all of it is spent and none is billable.
Other trades can send half a crew or come back Tuesday. You can't pave half a day, and hot mix doesn't go back in the silo. A plant slot can't be un-booked at six in the morning either. When the utility sub is still in the trench at daylight, the slot, the trucking, and the crew are already committed and non-recoverable, and a same-day standby claim against a GC almost never gets paid.
The size of it
A blown paving day is $6,000 to $15,000 of crew, trucks, and lowboy with zero revenue against it, and it gets charged to the job that got cancelled. That job's margin takes the hit for a delay somebody else caused, and nothing on the report says so.
A paving day is a package you buy in advance, and once it's bought you own it whether the grade is ready or not. Mix is ordered against a plant production slot days ahead, and trucking is booked by the day from a broker or an owner-operator pool. By daylight, eight to twelve trucks and the crew are on site. The spec gates the day as well. You need at least 50°F and rising, and no placement goes down on wet or frozen subgrade. Below 40°F the mat cools faster than the rollers can catch it. Paving sits behind utilities, curb, and fine grading, so the last trade in front of you decides whether your day happens at all.

How to charge a GC for a cancelled paving day?
The plant slot gets bought days ahead, along with eight to twelve trucks and a full crew. When the grade isn't ready at six in the morning, all of it is spent and none is billable.
What does it cost?
A blown paving day is $6,000 to $15,000 of crew, trucks, and lowboy with zero revenue against it, and it gets charged to the job that got cancelled. That job's margin takes the hit for a delay somebody else caused, and nothing on the report says so.
What do I do first?
Require a written grade-ready confirmation from the GC's superintendent 48 hours before every scheduled paving day, and make the walk yourself.
What are paving contractors supposed to be making?
Paving runs 20% gross margin, 14% overhead and 6% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points below it. The CFOS target is 10%.
Which part of the system fixes it?
The step is number 06, project management. Billing dates, change orders, and notices, run as standards that hold without anyone chasing them. It comes from chapter 6 of CONTROL: The Construction Financial Operating System.
