UNDERGROUND UTILITY CASH FLOW

PIPE PROCUREMENT IS
A UTILITY CASH PROBLEM.

THE SHORT ANSWER

Underground utility contractors order pipe 8–12 weeks before the trench opens. The pipe arrives at the yard before the site is ready. Installation happens weeks later. Billing triggers after installation. Collection comes 45–60 days after that. From deposit to cash can run 120–150 days. On a $300K pipe package, that's $300K out the door for five months before it comes back. Multiply by two jobs and you're at $600K of perpetual float requirement.

THE PROCUREMENT CYCLE

WHY UTILITY PROCUREMENT
DRAINS CASH STRUCTURALLY.

The procurement-to-payment timeline on a utility job is longer than almost any other trade. It's not a GC problem or a supplier problem. It's a structural feature of underground work: the material has to arrive before the ground opens and gets paid long after it's in the ground.

01
LONG-LEAD PIPE ORDERS
Large-diameter pipe, ductile iron, and specialty fittings can run 8–16 week lead times. The order goes in before site prep is complete — sometimes before the contract is fully executed. The deposit goes out immediately. By the time the trench opens, the cash has been out for two to three months with no billing event in sight.
02
DELIVERY BEFORE INSTALLATION WINDOW
Pipe arrives when the supplier can deliver — not when the installation crew is ready. Coordinating delivery with the trench schedule means material often sits in the yard or on-site laydown for 2–4 weeks before installation begins. That's 2–4 additional weeks of carrying the full material cost with no billing event triggered.
03
INSTALLATION-BASED BILLING STRUCTURE
Most utility SOVs are structured by installation milestone: pipe in the ground, tie-ins complete, testing complete. The billing event triggers after installation — meaning the entire procurement and staging period is uncompensated from a billing standpoint. Without stored materials billing, the only way to recover procurement cost is to get work in the ground first.
04
FITTINGS AND APPURTENANCES ADD UP
Main pipe is visible and trackable. Fittings, couplings, valves, service saddles, and appurtenances often get lost in a miscellaneous material line. On a $1M utility job, fittings and appurtenances can run $80K–$120K — ordered early, delivered piecemeal, and billed at installation completion. Tracking stored fittings separately is the difference between billing $400K and billing $520K in month two.
THE FIX

HOW TO COMPRESS THE
PROCUREMENT CASH GAP.

1

STORED MATERIALS LINE IN EVERY UTILITY SOV

Every utility contract with significant pipe value should have a stored materials line item negotiated before contract execution. The line covers pipe, fittings, and appurtenances at delivery — not installation. This single SOV negotiation compresses the procurement-to-billing gap from 60–90 days to 5–10 days on major material deliveries.

2

TRACK FITTINGS AND APPURTENANCES AS A SEPARATE STORED MATERIALS SCHEDULE

Don't let fittings disappear into a miscellaneous line. Build a stored materials schedule that itemizes pipe by size and quantity, fittings by type, and appurtenances by item. Photograph at delivery. Tag and stage in a designated laydown area. Each delivery becomes a billable event — not a miscellaneous charge that gets absorbed into the installation milestone 6 weeks later.

3

MAP PROCUREMENT PAYMENTS TO THE 13-WEEK CASH FORECAST

Every pipe order has a deposit date and a delivery date. Every delivery triggers a potential billing event. Map those dates against the billing collection schedule in the 13-week forecast. The gaps where procurement payment precedes billing collection by more than 30 days are LOC draw candidates — draw in advance of the gap, not after the bank account is low.

FAQ

COMMON QUESTIONS.

Utility contractors order pipe and fittings 8–12 weeks before installation, pay deposits or full invoice on delivery, and then wait through the installation phase and a 45–60 day GC payment cycle before collecting. The total gap from deposit to collection routinely runs 120–150 days on large pipe packages. That's pure capital requirement.

Three strategies: negotiate stored materials billing in the SOV so pipe can be billed at delivery rather than installation; structure the SOV with a mobilization and material recovery line billable at contract start; and build a 13-week cash forecast that maps procurement payments against expected billing collection dates so the LOC can be drawn before the gap hits.

A stored materials schedule listing pipe sizes, quantities, linear footage, unit values, and storage location. Photos showing pipe tagged and staged. Certificate of insurance covering the stored value. For off-site storage, a bonded warehouse agreement naming the GC as additional insured. GC approval secured before the first billing event.

Model the full procurement float: deposit payments to pipe suppliers plus fittings and material delivery costs, minus any upfront contract mobilization billing recovery. On a $4M utility contractor running two simultaneous jobs with $300K in pipe orders each, minimum LOC capacity for procurement alone is $600K. Most utility contractors are significantly underbanked for their actual float requirement.
