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'S 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 no scope was ever written 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.

That slab has to reach roughly 3,000 to 4,000 psi before it can support 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. Once the panels are set, 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 behind it.
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.
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.

What are tilt-up contractors supposed to be making?

No survey separates tilt-up, so there is no figure of its own. The nearest comparable trade in the reference is Concrete, which runs 21% gross margin, 14% overhead and 7% net profit before taxes at $1M–$5M, with a CFOS target of 10.5% net. Those are derived figures, not tilt-up's own. Read them 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.

If you would rather buy the finished result, SPM The Construction CFO does this work for tilt-up contractors as a service. It is a separate firm, Sulphur Prairie Management, LLC, run by the same author.
