Price Escalation in Contracts
Some contracts adjust for material and labour price movement. Many do not. Which one you are bidding on should change your price.
Read the clause before you bid, not after prices move
A price adjustment or escalation clause allows the contract value to move with published indices for materials, fuel and labour. Longer contracts more often have one; short ones often do not.
The mistake is bidding a long contract at today's prices without checking whether escalation applies. If it does not, you have absorbed eighteen months of price risk at a margin that assumed none.
This is a bid-stage decision. Once the contract is signed, a clause that is not there cannot be argued into existence.
How escalation generally works
- It follows published indices rather than your actual invoices. Your steel cost rising is not the trigger; the index moving is.
- It applies to specified components in stated proportions, not to the whole contract value.
- There is often a threshold below which no adjustment is made.
- It can work downwards. If indices fall, the adjustment can reduce your payment.
- It has to be claimed, with the calculation, in the bills. It is not applied automatically.

If there is no escalation clause
Then the price risk is yours for the whole contract period, and that has to be in your bid. For a two-year contract on volatile materials, that is a real number, not a rounding allowance.
Contractors who bid fixed-price work at spot rates and hope are the ones who finish contracts at a loss and blame the market. The market did what markets do; the bid did not account for it.
