This is the latest issue of the ABIC Major Works contract, launched in 2018, and can only be used for housing projects. Under the Home Building Act 1989 (HBA), projects for residential building work, with a contract price of more than $20,000, must use a HBA-compliant form of contract like the MW H NSW. The MW H NSW contract adopts stage payments prescribed by the HBA, instead of the ABIC-standard monthly progress payments.

The MW contract should be selected to suit each individual project, taking account of its complexity, value and any specific project issues or requirements. Compared to the Simple Works (SW) contract, the MW also provides contract mechanisms for:

+urgent instructions +separable parts to the works (staged practical completion) +change of type of security +security from owner to contractor +dangerous or contaminated materials +encroachments +quality assurance systems +separate contractors.
