TILT-UP · CONCRETE AND MASONRY · FIXED BY STEP 01

You bid the floor slab once and build on it twice

You pour the building's floor slab and then beat it up for weeks as a casting bed. The repair pass was never in the number, so you fix it on your own dime.

WHY IT IS A TILT-UP PROBLEM

Most trades damage somebody else's substrate and get back-charged for it. Tilt-up is the one trade whose deliverable is also its work platform, so the contractor signs for both conditions and only gets paid for one. The estimator prices a slab while the field builds a factory on it, and the difference between those two things is a job nobody wrote a scope for.

WHAT IT COSTS

The size of it

A whole-footprint grind, patch, and joint repair hits the job as labor and rental weeks after the panels are up, with no line item behind it and nothing on a pay application to cover it.

NO PUBLISHED BENCHMARK FOR THIS TRADE

No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. It reports inside NAICS 238110 Poured Concrete, so there's no tilt-up margin figure to put in this box. The 48 trades that do publish average 7% net profit at $1M–$5M before taxes, which is the nearest reference point worth anything here.

That slab has to reach roughly 3,000 to 4,000 psi before it can carry panel casting at all. After that, bond breaker gets fogged and rolled in two perpendicular coats, and layout gets chalked across the whole floor. Forms get pinned into the slab, rebar chairs and pump traffic ride on it, and the pick itself drags panel legs across it. When the panels are standing, the owner accepts that same surface as finished floor. Restoration is a full second trip over the entire building footprint, and the grinding, patching, and joint repair all bill as labor and rental after the crane has gone home.

WHAT TO DO

Three moves, in order

STEP 01

Open a slab restoration cost code and load it in the estimate at the same square footage as the casting bed, before you price a single panel.

STEP 02

Walk the slab with the owner's rep the day bond breaker goes down and again after the last pick, with dated photos, so the change in condition has a record and a change order has something to stand on.

STEP 03

Track the grind, patch, and rental hours against that code on this job, and use that number as the line on the next bid.

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.

BENCHMARKS

Tilt-up 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 tilt-up contractors money

TILT-UP · CFOS-02

The longest lead item is a date on a crane calendar

The crane is booked for the 14th and the cylinder breaks decide whether you can use it. Standby costs are yours either way.

TILT-UP · CFOS-08

Panel joints leak years after you booked the profit

The building is three years old and water is coming through a joint. Yours is the first phone number they dial.

TILT-UP · CFOS-05

Nothing you buy for a panel comes in square feet

You know your price per square foot of panel cold. Ask for your cost per square foot and there's no answer, because every line you buy is measured in something else.

SAME MECHANISM, OTHER TRADES

The same mechanism in other trades

CIVIL

Four mobilizations, one mob line item

You clear and grub in month one, come back for wet utilities, come back again for paving subgrade at closeout, and the contract still carries one mobilization line.

CONCRETE

Six Trips Back for Pads and Sidewalks, One Unit Price

You were first on the site and you're still coming back for stairs, pads, curbs, and exterior flatwork, all priced inside a per-yard number that assumed you never left.

DRYWALL

You Go Back Six Times And Nobody Signs A Ticket

You hung the corridor in March and you're still sending a guy back in June, one hole at a time, on somebody else's dime.

QUESTIONS

What tilt-up owners ask

Who pays to repair the slab after tilt-up panels are cast on it?

You pour the building's floor slab and then beat it up for weeks as a casting bed. The repair pass was never in the number, so you fix it on your own dime.

What does it cost?

A whole-footprint grind, patch, and joint repair hits the job as labor and rental weeks after the panels are up, with no line item behind it and nothing on a pay application to cover it.

What do I do first?

Open a slab restoration cost code and load it in the estimate at the same square footage as the casting bed, before you price a single panel.

Are there published benchmarks for tilt-up?

No, and this site won't print one. No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. In the surveys it rolls into NAICS 238110 Poured Concrete, so the closest honest reference is the 48-trade table, where net profit at $1M–$5M averages 7% before taxes. Read that as the neighbourhood, and read your own job costing as the answer.

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.
