STRUCTURAL STEEL FABRICATION DEPOSITS AND CASH FLOW — LEAD TIMES, DEPOSITS, AND BILLING MILESTONES.
Structural steel procurement creates a specific cash flow problem that does not exist in other trades: a 25–50% fabrication deposit deployed at order placement with a 12–20 week gap before billing recovery begins. On a $400,000 steel package, that is $140,000 deployed today against billing that does not start for four months. The contractor who models this gap before placing the order can fund it from a planned LOC draw. The one who does not discovers the gap when the deposit clears and the cash position drops unexpectedly.
SPM models steel procurement deposits in the 13-week and 24-month cash forecast for structural steel subcontractors and negotiates SOV language that recovers procurement costs earlier in the billing cycle.
FABRICATION DEPOSITS, LEAD TIMES, AND BILLING MILESTONES — HOW THEY CREATE A SPECIFIC CASH GAP.
Paying for Steel Before It Arrives or Is Installed
Structural steel fabricators require deposits — typically 25–50% of the fabrication contract — at order placement. Lead times for structural steel fabrication run 8–20 weeks depending on complexity and shop backlog. A contractor who orders $400,000 in structural steel with a 35% deposit requirement deploys $140,000 in cash at order placement. The steel does not arrive for 12 weeks. It is not installed for 14–16 weeks. It is not billed until after installation. The $140,000 deposit has a 16–20 week cash gap before billing recovery begins. This gap must be in the cash forecast before the order is placed, not after.
How to Build the Schedule of Values for Steel Projects
A properly structured SOV for structural steel work separates material procurement from installation and creates billing milestones that align to cash events rather than completion milestones. A stored materials billing line — allowing billing of fabricated steel that has been paid for and is in the fabricator's shop but not yet delivered — reduces the cash gap by creating a billing event at the point the deposit is deployed. Not all GC contracts allow stored materials billing, but it is worth negotiating on large steel procurements. Alternatively, a mobilization billing line that recovers procurement deposit cost at project start reduces the same gap.
How Schedule Changes Create Cash Flow Problems on Fixed-Price Steel Contracts
When the steel is ordered and the project schedule changes — owner pushes start date, other trades are not ready, permit is delayed — the steel is fabricated on schedule but the project is not. The fabricator may charge storage fees. The billing milestone that was supposed to cover the deposit is delayed. The contractor has paid for steel that cannot be billed because the installation milestone has not been reached. Managing this risk requires notice to the GC when the schedule change extends the gap between deposit and billing, with a request for reimbursement of storage costs and schedule impact.
FOUR ACTIONS BEFORE THE ORDER IS PLACED.
The working capital sizing implication: A structural steel subcontractor consistently carrying $200,000–$400,000 in steel deposit exposure needs a LOC sized to cover that exposure plus operating costs. The LOC that is appropriate for a concrete or civil contractor of the same revenue may be insufficient for a structural steel contractor because of the deposit structure of steel procurement.
