What are the Australian Building Industry Contracts (ABIC)?

One of the benefits of using ABIC contracts in NSW is that they are more detailed than contracts issued by the Office of Fair Trading, while still being user-friendly for homeowners. These contracts allow for a range of commercial arrangements that are not typically found in HIA and MBA contracts, providing more flexibility for the parties involved.

ABIC contracts are suitable for a range of building projects, including commercial, residential, and public works. They are particularly useful for projects where an architect is involved in administering the contract, as they provide a clear framework for the parties to work within. For example, ABIC contracts may be suitable for a residential renovation project where the homeowner engages an architect to design and oversee the project, or for a commercial development project where the developer engages an architect to manage the construction process.

Types of ABIC Contracts

ABIC contracts offer a range of contract types for building projects that are administered by an architect. Understanding the different types of contracts available can help homeowners and builders to choose the right one for their project.

The most common types of ABIC contracts include Major Works, Simple Works, Commercial Costs Plus, Early Works, and Basic Works. 

  • Major Works contracts are designed for larger and more complex projects.
  • Simple Works contracts are better suited for smaller and simpler projects. 
  • Commercial Costs Plus contracts are used for projects where costs are difficult to estimate.
  • Early Works contracts are intended for projects that are in the planning or design phase. 
  • Basic Works contracts are designed for very small projects or for use as a subcontract for a larger project.

Each type of ABIC contract has its own set of rules and requirements, and it is important to choose the right one for your project to ensure that it is completed successfully. For example, a Major Works contract might be best suited for a large commercial development or public building project, while a Simple Works contract might be more appropriate for a residential renovation or addition.

By understanding the different types of ABIC contracts and their suitability for different projects, homeowners and builders can ensure that their projects are completed on time, within budget, and to a high standard.

Major Works vs. Simple Works

ABIC Contracts offer two main types of contracts: Major Works and Simple Works. 

The Major Works contract is suitable for larger building projects, typically those with a budget over $3 million, while the Simple Works contract is ideal for smaller projects such as residential renovations, extensions or alterations.

Major WorksSimple Works
For complex or large projects worth above $3,000,000For smaller projects worth between $500,000 – $3,000,000

The Major Works contract contains more detailed clauses and provisions than the Simple Works contract. It includes more specific requirements such as quality control, reporting and management of the works, and is generally considered to be more comprehensive. The Simple Works contract is a more streamlined version of the Major Works contract, with fewer provisions and clauses.

Major works contract conditions

When deciding which contract to use, it is important to consider the size, complexity and budget of the project. Major Works contracts are more suitable for large-scale projects that require a higher level of detail and supervision, while Simple Works contracts are more appropriate for smaller projects where the requirements are less complex. It is also essential to consider the legal and financial risks associated with each contract and ensure that they are appropriately addressed in the contract documentation.
