Extension of Time (EOT)
A contractual extension to the completion date, granted when a delay is caused by an event the contract places at the employer’s risk. It relieves the contractor of liquidated damages for the extended period — but it does not, by itself, pay for anything.
The distinction people miss is that time and money are separate claims. An extension of time protects you from liquidated damages. It does not compensate you for the cost of being on site longer — that is a prolongation cost claim, and it has to be made and evidenced separately. Winning an EOT and forgetting the money is a common and expensive mistake.
And an EOT is not granted because the project was late. It is granted because a specific event, at the employer’s risk under the contract, caused a delay to the completion date — which means causation has to be demonstrated against the programme, event by event, with contemporaneous records. Most EOT claims fail on evidence rather than on entitlement.
