Late Plate Puts a Certified Crew on the Bench
The plate is six weeks late and there's nothing else on that site your welders are allowed to touch.
A GC covers a material slip by pulling another trade forward. A tank erector has one to four dedicated crews and holds a single scope on that site, so the mill date moving is the whole job moving. The delay also belongs to the mill, which leaves no GC to file a claim against and no party to bill standby to.
The size of it
Six weeks of a five-man welding crew plus a crane on standby is $60K to $120K with zero revenue against it and no delay claim behind it.
Shell plate rolls to grade, width, and thickness in one heat lot so the Mill Test Reports trace back to the API 650 tank they belong to. Mills roll a given grade on a schedule, and missing that window turns a quoted 10 to 16 weeks into 20 or more. Your crew is certified welders, a jacking system, welding rigs, and a crane, and none of that redeploys to a different scope on the same job. There's rarely a second tank ready to start, so the choice is idle payroll or a layoff that sends trained welders to the shop down the road.

What tank and vessel owners ask
How to cover welding crew cost when mill plate is late?
The plate is six weeks late and there's nothing else on that site your welders are allowed to touch.
What does it cost?
Six weeks of a five-man welding crew plus a crane on standby is $60K to $120K with zero revenue against it and no delay claim behind it.
What do I do first?
Before you commit a crew start date, ask the mill for the rolling schedule covering your grade and width, and put the roll date on your schedule, not the promise date.
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 06, project management. Billing dates, change orders, and notices, written as standards that work without anyone following up on them. It comes from chapter 6 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.
