BRIDGE · CIVIL AND EARTHWORK · FIXED BY STEP 06

Your Girder Date Comes From the Casting Bed Calendar

You didn't buy beams, you bought a spot in a casting bed. The plant releases that spot when your shop drawings come back approved, and the calendar behind it belongs to somebody else.

WHY IT'S A BRIDGE PROBLEM

Most trades order material and take delivery on a schedule they control. On a bridge, the one item that fixes your erection date is made to order against a shared production line, and the release trigger is a state reviewer's signature on shop drawings. That puts your longest lead item under two parties who don't report to you and can't be paid to hurry.

WHAT IT COSTS

The size of it

Miss the bed slot and you queue behind whoever submitted next, commonly 6 to 10 weeks. By then the substructure is poured and paid for and the crane date is booked, so the crew stays on the clock with nothing to invoice against.

A girder is built for one bridge, with its own length, skew, strand pattern, camber, and bearing seat. The precast plant schedules by casting bed, and a bed casts one line a day, so your beams are a date on a board that fills in submittal order. Steel plate girders run further out still, because mill plate alone runs 10 to 12 weeks before the fabricator makes a cut, and then fit-up, weld, NDT, and coating follow. Money doesn't move any of it. A plant with a DOT job on the bed isn't bumping it for a $4M sub.

WHAT TO DO

Three moves, in order

STEP 01
Get the casting bed confirmation from the plant in writing at award, including the drop-dead date for approved shop drawings, and put that date on the schedule with one person responsible for it.
STEP 02
Work backward from the bed date through the review window to set the shop drawing submittal date, then check it every week until it clears.
STEP 03
Add the girder release to your monthly job review so the beams read as committed cost with a real delivery date before anybody books the crane.
QUESTIONS

What bridge owners ask

How long does it take to get precast girders after shop drawing approval?

What do I do first?

What are bridge contractors supposed to be making?

Bridge runs 22% gross margin, 15% overhead and 7% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade is right on it. The CFOS target is 10.5%.

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 chasing them. It comes from chapter 6 of CONTROL: The Construction Financial Operating System.
