Which contract should I use in Tasmania?

Selecting the right contract can be tricky. Making sure you pick the best contract for your project will set you up for success throughout the building work.

HIA has a range of contract options to suit both domestic and commercial building work.

Use the chart below to help you make the right choice.


Choosing the right contract

What else do I need?

HIA has a range of supporting documents available to help you administer the contract during the building work.

Preliminary agreement 

This agreement is for use when you have to do work before you sign the contract for example, getting foundations data (i.e. work including footings and foundations which the law requires you to obtain before a domestic building contract is signed). The preliminary agreement is the best way for a building contractor to ensure payment for pre-contractual work and preparation.

Variation document 

This document satisfies the requirements of domestic building laws that variations must be in writing and must include specific details. If you do not satisfy the legal requirements but complete the work anyway, you may not be entitled to be paid for the variation. 

Notice of Suspension 

This notice is for use when suspending building works under the contract. The notice provides the owner with details of why works are being suspended and details any moneys payable as a consequence of the suspension.

Notification of extension of time 

This form is to notify the owner of an entitlement to an extension of time when the carrying out of the building works is delayed. If you do not notify an owner about your entitlement to an extension of time when the right arises (e.g. at the time of the delay), you may not be able to claim this time down the track and may have to pay agreed damages for late completion of the building works. This form has been designed for use in conjunction with most HIA contracts.

Notice of Completion 

This notice is used to formally notify an owner when the contracted domestic building works are complete. It also is used to initiate the owner’s inspection of the works as part of the hand over and payment procedure.

Where can I get these documents? 

HIA’s Contracts Online is your go-to platform for creating professional and secure building industry contracts.
