Can LDs be deducted from a progress payment under SOPA?

Answer

The respondent must state any amount withheld, with reasons, in the payment response; objections not raised there generally cannot be raised later in adjudication. The Act also tells adjudicators to disregard claims for damage, loss or expense that are not supported by an agreement on quantum or a certificate required by the contract. Owners should therefore have any required delay certificate in place before deducting, and take legal advice on contested deductions.

From the RRD Field Guide, checked against the sources cited in Liquidated Damages and Extension of Time in Singapore: An Owner's and Contractor's Guide. General information, not advice for your project.

The fuller picture

In Singapore, a liquidated damages clause is enforceable if it is a genuine pre-estimate of loss and not a penalty; the Court of Appeal in Denka Advantech (2020) kept the traditional Dunlop test and declined the UK Cavendish approach. LDs only run for delay the contractor is responsible for, so the contract needs a clear extension-of-time clause, notice rules and a certification step.
