The Mill Rolling Schedule Owns Your Barge Date

The mill gave you a November rolling slot and the barge is booked for September. Nobody at the mill pays for the six weeks your spread sits.

WHY IT IS A MARINE PROBLEM

A shoreside trade can start on something else while a long lead item catches up. A marine sub can't, because the pile is the foundation, the trestle, and the work platform all at once, so nothing moves until steel or timber gets delivered to the water. Waiting isn't cheap either: equipment stays on charter by the day, crewed and tied off, burning money whether or not a hammer swings.

WHAT IT COSTS

The size of it

A chartered crane barge with a tug runs roughly $4,000 to $12,000 a day on the Gulf and East Coast, and idle days carry no pay item. Six weeks of a spread waiting on steel exceeds the entire gross margin on a $600K bulkhead.

Hot rolled sheet pile in your specified section and pipe pile in your specified wall come off a mill rolling schedule for that section, and when a distributor isn't sitting on it, that's commonly 12 to 30 weeks. Treated timber piling adds a second clock, which is length: anything over 60 feet comes from a short list of treaters and waits on a treatment cycle you don't control. Meanwhile the spud barge, crane barge, tug, and workboat were committed or chartered by the day against a date you locked months earlier. When the mill slips, the whole floating spread sits stranded with no pay item attached to it.

WHAT TO DO

Three moves, in order

STEP 01

Get the mill's written rolling slot and the treater's cycle date before you sign, and set your barge charter window off that date.

STEP 02

Open a standby cost code for each floating asset, so a mill slip reads as a dollar number the week it starts and not at closeout.

STEP 03

Write a material availability clause that moves your mobilization date when the mill moves theirs, and forward the mill acknowledgment to the GC the day it comes in.

THE FIX

Step 02: Equipment cost basis

A true internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it.

ACROSS EVERY TRADE

Your equipment is eating the margin

The machine is paid for, so the jobs use it at no charge. Then the transmission goes and the year is gone.

SAME TRADE

What else costs marine contractors money

MARINE · CFOS-06

Corps Permit Conditions Hit After Your Price Is Locked

You signed in March and couldn't put a hammer in the water until October, and the permit that held you up belongs to the owner.

MARINE · CFOS-04

You Buy Pile by the Ton and Bill It by the Foot

Every cutoff on the barge is footage you already paid for and will never invoice. The same mismatch runs backwards on dredging.

MARINE · CFOS-07

Retention Releases on a Survey You Never Ordered

Ten percent of your scope sits behind a hydrographic survey the owner commissions and a mitigation report your crew has no control over.

MARINE · CFOS-01

One Mob Line Never Covered Three Barge Tows

You mobilized the spread three times on a job you bid one mobilization for, and the second and third came out of your margin.

MARINE · CFOS-03

The USL&H Audit Reopens a Year You Already Closed

The comp audit came back for forty grand you never saw coming, against a year that was already booked as profitable.

SAME MECHANISM, OTHER TRADES

The same mechanism in other trades

CONCRETE

Eight Tons of Rebar Tagged to a Drawing That Changed

The EOR approved the placing drawings, the fab shop cut and bent to the bar list, and then somebody moved a footing. Now you own bundles tagged to grid lines that no longer exist.

DEMOLITION

Your Breaker Burns Tool Steel That Overhead Pays For

A hammer chews $9,000 of tool steel on one teardown and the job that ate it never sees a dollar of the cost. The margin looks fine and the bank account disagrees.

DRYWALL

Lead-lined board is eight weeks and non-returnable

The imaging room's board is eight weeks out, cut to the shielding drawings, and the deposit is gone the day you release the order.

QUESTIONS

What marine owners ask

Sheet pile mill lead time wrecking my barge schedule?

The mill gave you a November rolling slot and the barge is booked for September. Nobody at the mill pays for the six weeks your spread sits.

What does it cost?

What do I do first?

Get the mill's written rolling slot and the treater's cycle date before you sign, and set your barge charter window off that date.

What are marine contractors supposed to be making?

Marine runs 22% gross margin, 15% overhead and 7% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits right on it. The CFOS target is 10%.

Which part of the system fixes it?

The step is number 02, equipment cost basis. A true internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it. It comes from chapter 2 of CONTROL: The Construction Financial Operating System.
