CASE STUDY · SITEWORK CONTRACTOR

ONE RATE FOR THREE THINGS. PAST SIX HOURS IT LOST MONEY.

QUICK ANSWER

A site work and civil contractor came to us at $550,000 annualized in a partial first year. He wasn't in trouble. After thirty years of starting and owning businesses he knew his own habit: run flat out to survive, put off cash flow and systems until it's too late. This time he wanted the system built first. His time and material rate turned out to be the fault, and it was invisible because the work was profitable enough to cover it. He billed operator, machine and fuel as one combined number, so anything past a six hour day lost money and nothing reported it.

The ticket said something close to excavator operator, $650, nine hours. That is a number nobody can check, including the person writing it. Itemizing it raised his price 15 percent and the customer preferred the new invoice, because for the first time it showed what they were buying.

THE SITUATION

A $550K SITEWORK SUB. HE WANTED THE SYSTEM BEFORE THE CRISIS.

A site work and civil contractor at $550,000 annualized in a partial first year, with one primary customer sending regular hourly work at a decent profit. He knew the concentration was a threat and he wanted to know what it cost to run his business before he started bidding competitive work.

THE PROBLEM

ONE COMBINED RATE, THREE DIFFERENT COSTS.

He billed a flat rate with the operator, the machine and the fuel inside it. Nothing in that number carried overtime, additional fuel burn on a long day, insurance, or general maintenance on the machine.

So the rate worked for a normal day and reversed on a long one. Past about six hours the combined number stopped covering what the day cost, and because the three components were never separated, no report could show which one had moved.

The reason it survived is that the work was good. Profit on the underlying jobs was healthy enough to absorb the loss on long days, so the business felt fine while a structural pricing fault ran underneath it.

WHAT WAS REALLY WRONG

A NUMBER NOBODY COULD VERIFY.

The tickets told the story. Excavator operator, $650, nine hours. One line, one price, three costs inside it and no way for anyone to audit any of them. The customer couldn't check it and neither could he.

Breaking it apart made each component answerable. What does the machine cost per day to own, fuel and maintain. What does the operator cost fully burdened, including the hours past eight. What does insurance on that machine cost against the days it really works.

The estimating review that followed put the honest price 15 percent above what he had been charging. He was certain the customer would refuse it.

Job Profitability System
THE INTERVENTION

WHAT CHANGED, WEEK BY WEEK.

Weeks 1 to 3: Broke the combined rate into its parts and charged equipment per project: machine, fuel, man hours, insurance and maintenance, each on its own line.
Weeks 2 to 4: Rebuilt the estimating review around those figures, which put the honest price about 15 percent above the old combined rate.
Weeks 3 to 8: Went after customer concentration deliberately, moving from one primary customer to eight contractors in the fold inside 55 days.
Week 6 onward: Issued itemized tickets showing machine, fuel and labor separately, so a customer reviewing an invoice could see what each part cost.
THE OUTCOME

THE NUMBERS, NOT THE FEELING.

1 TO 8
Customers, in 55 Days
+15%
Pricing, With No Customer Lost
6 HOURS
The Day Length That Used to Cost Him
5 LINES
Machine, Fuel, Labor, Insurance, Maintenance

Fifty five days from first call to eight contractors in the fold at the new pricing. The rate rebuild took about four weeks, and the diversification ran alongside it, never after, which is what made the next part survivable.

WHAT THIS MEANS FOR OTHER CONTRACTORS

DOES THIS SOUND FAMILIAR?

Two things put a contractor in this position. The first is a combined billing rate. If your ticket carries one number for machine plus operator plus fuel, you cannot know which of the three moved when a job goes wrong, and a long day is the most common way it goes wrong.

The second is a customer who is most of your revenue. This one was profitable and reliable, which is what makes concentration so hard to act on. The work is good, the relationship is good, and the risk is invisible until the day it isn't.

The test is simple. Take your last time and material ticket and try to justify each dollar in it to somebody who has never seen your business. If you can't, your customer can't either, and neither of you can tell whether the price is right.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because the three costs inside it move at different speeds. The machine costs roughly the same whether it works six hours or eleven. The operator costs more past eight, at overtime. Fuel burn rises with hours run. A single combined number is calibrated to one day length, usually a normal one, so every hour past that point is priced at the average of three costs that are no longer average. Here the crossover sat at about six hours, and past it every hour cost him money with nothing reporting it.
That was this owner's fear and the opposite happened. He was certain a 15 percent rise would be refused, and the customer preferred the itemized ticket, because for the first time they could see what they were paying for. A single line reading operator, $650, nine hours gives a customer nothing to agree with. Machine, fuel, labor, insurance and maintenance on separate lines is a document somebody can check, and checkable prices are easier to defend than round ones.
The published engagement band is $1M to $12M, so this contractor sits below where the monthly service starts. He is here because the sequencing is the lesson: after thirty years of businesses he had learned that he always put cash flow and systems off until it was too late, and this time he built them at $550K instead. The pricing fault he found would have scaled with him. Found at $10M it would have been a much more expensive correction.
