Contract particulars

The contract particulars are the schedule of a standard-form building contract where the parties fill in the job-specific values that turn a template into a binding agreement: the contract price, the deposit, the building period (with start and finish dates), the liquidated damages rate, and the prime cost (PC) and provisional sum (PS) allowances. The clause wording in the body of the contract is fixed; the particulars are the blanks that make it your job rather than anyone’s.

In the HIA NSW Residential Building Contract, for example, these sit in Schedule 1, and the liquidated damages rate is Schedule 1, Item 11. MBA contracts use an equivalent schedule. The particulars are not boilerplate to skim past: a blank or careless entry has real consequences. Leave the liquidated damages rate blank and the HIA contract defaults to $1 per working day, which the courts have held is effectively nominal and does not cap the builder’s delay exposure (Carbone v Fowler Homes [2024] NSWCA 192). Undercook the PC and PS allowances and the contract price is misleading from day one.

Fill the particulars in fully and accurately before signing, not after. Every job-specific number a dispute later turns on, the price, the dates, the damages rate, the allowances, lives here, so it is the first part of the contract to get right. See reading a building contract and the HIA fixed-price contract for how the particulars drive the rest of the document.

Also known as: Contract Particulars, Schedule of Particulars, Schedule 1 (HIA), contract information schedule.
