Escalation and Material Volatility on a Multi-Year Schedule
You are pricing a two-year phased school project. Copper wire and conduit are roughly 18% of direct material cost. Over the past 24 months copper has swung ±25%, and your supplier will only hold pricing for 90 days. The contract is lump-sum with no escalation clause, and the owner has rejected a price-adjustment provision. Your estimate uses today's copper price. Phase 2 material is purchased roughly 14 months out. Your finance team's internal forecast expects copper to rise 10% over the next year, with a wide band of uncertainty.
1. How do you reflect copper exposure in a lump-sum bid with no escalation clause?
Read the worked answer
You are carrying the price risk, so quantify it and decide deliberately how much to hold.
- Exposure base: Copper/conduit is 18% of direct material. If direct material is, say, $1.2M, copper exposure is $216,000.
- Timing: Phase 2 buys 14 months out, beyond the 90-day supplier hold, so essentially all of Phase 2's copper is exposed.
- Forecast: A 10% expected rise implies roughly $21,600 on the full exposure; a ±25% swing implies a range of about −$54,000 to +$54,000.
Options: (a) price today's cost and carry a risk allowance sized to the forecast plus a margin for the band; (b) lock pricing via futures or a supplier agreement where feasible; (c) buy early and store material, accepting carrying cost. Because no escalation clause exists, the risk allowance is your only protection - size it to the realistic band, not the point forecast, and document the basis. Under-pricing this is the classic lump-sum trap.
2. The owner offers to add an escalation clause capping adjustment at 8%. Should you accept, and how does it change your bid?
Read the worked answer
A capped escalation clause shifts part of the tail risk back to the owner, so it is generally favorable and worth negotiating.
With an 8% cap: your downside beyond +8% is transferred to the owner; you still carry moves up to 8% and all downside moves below the cap. That reduces the risk allowance you must embed. If your unhedged allowance was sized to a ±25% band, the cap lets you shrink it to roughly the 8% band plus a modest buffer.
Decision: accept the clause, but read the mechanics - what index, what baseline date, and whether it covers only copper or all material. A cap on the wrong index or a stale baseline provides little protection. Recompute the allowance against the capped exposure and reduce the bid accordingly, which also improves competitiveness. Document the revised basis so the reduction is traceable to the clause, not to optimism.
