ABIC contracts

Read time: 3 minutes

The Australian Building Industry Contracts (ABIC) are jointly published by Master Builders Australia Limited (Master Builders) and the Australian Institute of Architects (Institute). They are intended for use in building projects where an architect administers the contract. 

The 2018 revised editions of the ABIC Major Works (MW) and Simple Works (SW) commercial and domestic documents and template forms (previously called Contract proforma) are now available under the relevant state and territory pages (navigate the side right menu for relevant page).

For a revised edition of the ABIC Basic Works (commercial) contract refer to ABIC Basic Works BW 2018.

ABIC contracts information

ABIC contracts are designed to make contract administration clear and less prone to dispute or time-consuming negotiation. ABIC contracts bring certainty to the process, requiring timely presentation and resolution of claims. They have been extensively refined and field-tested and feature:

  • plain English and a clear, logical structure that reflects the sequence of the construction process;
  • equitable allocation of virtually all project risks to one party or the other, eliminating uncertainty and many potential disputes;
  • an integrated suite of versions for major, simple and basic works, and for housing and non-housing projects; and
  • detailed supporting documents, including a user guide, template forms for the architect and the contractor.

Selecting the right contract

There are different contracts for each state and territory for various types of projects. Selecting the right building contract can be critical to the success of a project.

The contract should be selected to suit each individual project, taking account of its complexity, value and any specific project issues or requirements. A contract selected simply because the architect is familiar with its provisions or is comfortable using it, won’t overcome the inherent difficulties that can arise if the contract is inappropriate for the project.

Differences between SW and the MW contract

The SW contract is intended for simpler projects than MW contract. The MW contract is the most comprehensive contract in the ABIC suite of building contracts. Although the differences are numerous, notable differences between the contracts are summarised in the table below:
