TANK AND VESSEL · SPECIALTY · FIXED BY STEP 04

The Plate Quote Expired Before You Won the Job

You bid the tank in March, won it in July, and bought the plate in August against a mill quote that expired in April.

WHY IT'S A TANK AND VESSEL PROBLEM

Most trades buy material in weeks, in lots small enough that a price move is noise. On an API 650 or AWWA D100 tank, plate is 30 to 45 percent of contract value and it all buys in one heat lot at one moment. SteelBenchmarker had USA standard plate at $1,520 per tonne in August 2026 against an $860 low in January 2025, so the swing across a normal municipal award cycle is bigger than the margin on the job.

WHAT IT COSTS

The size of it

On a $2.5M tank with a $900K plate package, a 25 percent move between bid and buyout is $225K, roughly the entire estimated gross profit on the job before a single course goes up.

OVERHEAD AT $1M to $5M

15%

CFOS target 14% for tank and vessel.

GROSS MARGIN AT $1M to $5M

23%

CFOS target 25.5% for tank and vessel.

NET PROFIT AT $1M to $5M

CFOS target 11.5% for tank and vessel.

The plate package is the largest single line on a field-erected tank, and you priced it off a mill quote that lives 15 to 30 days. The award cycle that follows belongs to somebody else: bid opening, engineer's recommendation, council approval, funding release, then bond and insurance. By the time notice to proceed comes through, you're 60 to 120 days past that quote, and hard-bid public work won't accept escalation language. You hold the entire plate position uncovered across a window you don't control.

WHAT TO DO

Three moves, in order

STEP 01

Pull your last three tank bids and write three dates side by side: bid date, mill quote expiration, and buyout date. The distance in days between the first and the last is your exposure window.

STEP 02

Price plate escalation as its own visible line in the estimate with a stated price-hold deadline in the proposal, so on negotiated work you've something to point at and on hard-bid work you at least priced the risk.

STEP 03

Set up a dedicated plate cost code so buyout variance posts against the estimate the week the PO drops, not at closeout.

THE FIX

Step 04: Estimating system

The estimate maps one to one onto the job cost codes, so variance means something the day it appears.

Make the estimate and the job cost report match

BENCHMARKS

Tank and vessel by revenue band

All 7 bands are published. The CFOS target is beside the figure up to $10M to $25M, and the 4 bands above that are labelled modeled.

ACROSS EVERY TRADE

The estimate and the actual never match

You can compare the estimate to the job cost report, but the two use different words, so the comparison means nothing.

SAME TRADE

TANK AND VESSEL · CFOS-06

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.

TANK AND VESSEL · CFOS-01

You Pay for Coupons Before You Bill a Weld

Four welders spent two weeks cutting and testing coupons, and none of that time had a job number behind it.

TANK AND VESSEL · CFOS-07

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.

TANK AND VESSEL · CFOS-08

Year Two Blisters Come Back to a Closed Job

The liner blistered in year two, the utility will only let you drain that tank in a low-demand window, and the job closed out two fiscal years ago.

TANK AND VESSEL · CFOS-04

You Sell in Gallons and Buy in Pounds

Seismic revisions bumped two shell courses, your plate order grew by 25,000 pounds, and the owner still calls it a 500,000-gallon tank.

SAME MECHANISM, OTHER TRADES

The same mechanism in other trades

CIVIL

You bid cubic yards and pay by the ton

You bid 40,000 yards of import and every scale ticket comes back in tons. The biggest cost line on the job is measured in a unit your contract never defined.

CONCRETE

Your Ready-Mix Quote Expired Eleven Months Before the Pour

Concrete has about a 90-minute working life from batch to placement, so your supply market is a haul radius with two or three plants. They quoted a market that's gone.

DEMOLITION

Your Bid Set A Scrap Price The Market Never Honored

You priced the steel credit in February and crossed the scale in October. The market moved and the subcontract had no escalation language for it.

QUESTIONS

What tank and vessel owners ask

Steel plate price went up between tank bid and buyout?

You bid the tank in March, won it in July, and bought the plate in August against a mill quote that expired in April.

What does it cost?

On a $2.5M tank with a $900K plate package, a 25 percent move between bid and buyout is $225K, roughly the entire estimated gross profit on the job before a single course goes up.

What do I do first?

Pull your last three tank bids and write three dates side by side: bid date, mill quote expiration, and buyout date. The distance in days between the first and the last is your exposure window.

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 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: C.F.O.S. Construction Financial Operating System.
