Cut-off Piles Turn Your Salvage Credit Into Zero
You locked sheet pile pricing at bid and bid the same steel a second time as salvage. Then an obstruction forces cut-off, and the residual you counted on stays in the dirt.
A permanent-install trade prices material once and it stays in the building forever. You price the same steel twice, once going in and once on the assumption it comes back out and gets reused on the next job. That second price is a bet on site conditions and other people's specs, buried inside a hard bid you don't get to reopen.
The size of it
You take two margin hits on one line: the buyout escalation, and the salvage that never comes back to the yard. Both of them happen after the price is fixed.
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 238910 Site Preparation, so there's no shoring and shielding 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.
Sheet pile, wide-flange soldier beams, and box steel are the biggest material lines in this scope. Price gets locked at bid and bought at buyout, with steel tariffs at multi-decade highs and escalation language routinely refused on hard-bid public work. That's the first exposure. The second one is harder to see: temporary steel is bid net of a salvage or reuse assumption, so part of the buy is expected back in your yard and priced accordingly. If an obstruction, a spec restriction, or an adjacent structure forces the piles to be cut off and abandoned, that residual disappears and the whole steel buy becomes consumed cost on a number fixed months earlier.

How to bid sheet pile when the piles might have to be cut off and left in place?
You locked sheet pile pricing at bid and bid the same steel a second time as salvage. Then an obstruction forces cut-off, and the residual you counted on stays in the dirt.
What does it cost?
You take two margin hits on one line: the buyout escalation, and the salvage that never comes back to the yard. Both of them happen after the price is fixed.
What do I do first?
Split the steel line in the estimate into steel purchased and salvage credit assumed, as two codes, so the credit is visible to you and to whoever reviews the bid.
Are there published benchmarks for shoring and shielding?
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 238910 Site Preparation, 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 04, estimating system. The estimate maps one to one onto the job cost codes, so variance means something the day it appears. It comes from chapter 4 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
