You Finish First and You Get Paid Last
The tank has been holding water for eighteen months, the city loves it, and the owner still has your retainage.
Trades that finish near the end of a project wait weeks for retention. A tank goes up early and gets tested early because everything built after it depends on it, so the stretch between your last day of work and your last dollar is the longest on the job. You're also funding the next tank's plate package during that same stretch, which is how a shop with good margin still ends up with no cash.
The size of it
On a $2.5M tank, 10 percent is $250K held for 18 to 24 months after your crew left the site, financed at your line of credit rate.
Your tank is on site four to ten months. The treatment plant, terminal, or industrial build it belongs to lasts 24 to 36 months, and retention at 5 to 10 percent releases at substantial completion of the whole project, which is a different date than the day your tank passed test. Repaint and rehab work works differently and ends the same way: eight to sixteen weeks of physical work, then the owner's engineer holds retention against a coating warranty that lasts one to three years on an interior lining. Either way your money is stuck behind a clock that only starts once you've demobilized.
Three moves, in order

What tank and vessel owners ask
Tank subcontractor retainage held until plant completion?
The tank has been holding water for eighteen months, the city loves it, and the owner still has your retainage.
What does it cost?
On a $2.5M tank, 10 percent is $250K held for 18 to 24 months after your crew left the site, financed at your line of credit rate.
What do I do first?
Before you bid, read the retention clause and find the release trigger. Substantial completion of your scope and of the whole plant are two different dates and two different years.
What are tank and vessel contractors supposed to be making?
Tank and vessel has 23% gross margin, 15% overhead and 8% net profit after taxes at $1M to $5M. The all-trade average is 7%, so this trade is 1 point above it. The CFOS target is 11.5%.
Which part of the system fixes it?
The step is number 07, monthly cadence. Weekly bookkeeping, cost to complete, and one CEO report, on the same days every month. It comes from chapter 7 of CONTROL: C.F.O.S. Construction Financial Operating System.
Everything on this page is something you can install yourself, and CONTROL is the order to do it in. If you would rather buy the finished result, SPM The Construction CFO does this work for tank and vessel contractors as a service. It is a separate firm, Sulphur Prairie Management, LLC, led by the same author.
