A pre-agreed daily or weekly sum the contractor pays for late completion: enforceable without proof of actual loss.

Liquidated damages (LDs) are a fixed sum specified in the contract that the supplier must pay for each day or week of delay beyond the agreed completion date. On Irish public works contracts (PW-CF series), LDs are set in the Schedule of Contract Particulars and apply automatically, the contracting authority does not need to prove actual loss. To be enforceable, LDs must be a genuine pre-estimate of likely loss; a punitive figure is unenforceable as a penalty. LDs are typically capped (often at 10% of the contract sum). Read the Special Conditions carefully: LD rates on Irish public contracts can be material to bid pricing.
