SCAFFOLDING · SPECIALTY · FIXED BY STEP 01

The clamps that never came back are hiding in your overhead

Eleven hundred clamps shipped and nine hundred came home. By the time you know that, the final pay app is cut and the GC's job budget is closed.

WHY IT IS A SCAFFOLDING PROBLEM

Loss and damage is scaffolding's warranty tail, and it comes due after closeout instead of during the work. A drywall sub knows its material variance the week the board is hung; you learn yours a month after the last truck rolls, when everyone who could have authorized payment has moved to another project. Because the missing item is a clamp and not a defect, there's no punch process, no callback, and no contractual mechanism waiting to receive it.

WHAT IT COSTS

The size of it

A large job can absorb ten to forty thousand dollars into overhead as shrinkage. Spread across a year that's real money, and it's charged to no job at all.

OVERHEAD AT $1M–$5M

18%

CFOS target 17% for scaffolding.

GROSS MARGIN AT $1M–$5M

26%

CFOS target 27% for scaffolding.

NET PROFIT AT $1M–$5M

CFOS target 10% for scaffolding.

Components get buried in backfill, cut for somebody's convenience, welded to, thrown down a chute, or loaded onto another contractor's truck at demob. You can't count any of it until the last load is back in the yard and banded, which is thirty to sixty days after final dismantle. At that point the final application for payment has gone out, retainage is in process, and the GC's job budget has no line left to pay a replacement invoice from. So the shortage gets written off, sits in overhead as shrinkage, and never touches the job that caused it. Every job then looks profitable for a reason that has nothing to do with what happened on it.

WHAT TO DO

Three moves, in order

STEP 01

Ship against a signed manifest by component type and quantity on every outbound load, and have the receiving super or your foreman sign the return count on every inbound load.

STEP 02

Count at each major raise or reconfiguration, not only at demob. A mid-job shortage is still billable while the job budget is open.

STEP 03

Put a loss and damage clause with published replacement pricing in the subcontract, notify shortages in writing within ten days of the count, and code the write-off to the job so the job report tells the truth.

THE FIX

Step 01: Job cost structure

Seven cost categories and three levels of granularity, built so the estimate and the ledger use the same words.

CFOS-01 · CHAPTER 1

Job cost codes that match how you bid the work

What this step changes, what it depends on, and how to tell it's installed.

BENCHMARKS

Scaffolding by revenue band

Every one of the 7 bands carries the CFOS target beside the published figure.

ACROSS EVERY TRADE

Cost codes the field ignores

You have 200 cost codes. The crews use four of them, and one is called Miscellaneous.

SAME TRADE

What else costs scaffolding contractors money

SCAFFOLDING · CFOS-01

Your rental line is funding the GC's cash for two years

The GC holds ten percent of your monthly rental invoice the way they hold it on installed work, and keeps holding it until the building is done. Nothing on rent waits to be completed.

SCAFFOLDING · CFOS-02

Owned steel sitting on a job costs that job nothing

A tower that ties up forty percent of your yard for fourteen months prices out identically to a three-month job using the same frames. Utilization lives nowhere in the accounting.

SCAFFOLDING · CFOS-06

Forty verbal adds a job never become change orders

Masons want a lift raised and painters want a deck moved. Two men go out for three hours, nobody signs anything, and the same call comes forty more times.

SCAFFOLDING · CFOS-06

Your erect date belongs to people who don't work for you

Crew is booked for the fifteenth and the drawings are still on the owner's engineer's desk. You don't control any of the three clocks that release the erect.

SCAFFOLDING · CFOS-04

You sell deck square feet and spend erector hours per lift

Ten thousand square feet at eight feet in an open garage and ten thousand square feet at ninety feet inside an occupied atrium bid identically. One of them costs double.

SAME MECHANISM, OTHER TRADES

The same mechanism in other trades

CIVIL

Trench dips appear inside the bond window

The parking lot settled over your sewer line eighteen months after acceptance, and who pays comes down to whether the density test for that station and that lift is in a file.

DEMOLITION

They Found A Tank A Year After You Demobilized

An old UST turns up under the pad twelve months after your last load left, and every finger points at the contractor who isn't on site anymore.

DRYWALL

The eleven-month callback hits this year's payroll

It's March, two of your best guys are in a truck all month fixing houses you finished last spring, and none of those hours bill.

QUESTIONS

What scaffolding owners ask

How to charge scaffold loss and damage back to the job?

Eleven hundred clamps shipped and nine hundred came home. By the time you know that, the final pay app is cut and the GC's job budget is closed.

What does it cost?

A large job can absorb ten to forty thousand dollars into overhead as shrinkage. Spread across a year that's real money, and it's charged to no job at all.

What do I do first?

Ship against a signed manifest by component type and quantity on every outbound load, and have the receiving super or your foreman sign the return count on every inbound load.

What are scaffolding contractors supposed to be making?

Scaffolding runs 26% gross margin, 18% overhead and 8% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points above it. The CFOS target is 10%.

Which part of the system fixes it?

The step is number 01, job cost structure. Seven cost categories and three levels of granularity, built so the estimate and the ledger use the same words. It comes from chapter 1 of CONTROL: The Construction Financial Operating System.
