‘Liquidated damages (LD) clauses are a fixture of construction contracts. As we all know, they are a secondary obligations to pay an agreed sum of money, arising upon breach of a primary obligation of the contract. In the case of a construction contract, this will invariably be in the event of delay: the failure to complete the works by a specified date.’
