QLD Building contracts and related documents

You are required to have a compliant written contract for domestic building work where the price is $3,300 or more. It also makes good sense to set out all the terms of your agreement in writing with the other party so each party can see what was agreed.
If you do not use a compliant contract, you may be fined (and have demerit points against your license). HIA has a suite of compliant contracts as listed below:

QC1 New Home Construction Contract

This contract may be used for the construction of a new home. The contract is a plain language, easy to understand contract that includes detailed schedules, general conditions, and a Contract Information Statement. The contract has a fair and balanced allocation of risk and although it is a full price contract, there is provision for variations requested by either party.

QC2 Peace of Mind New Homes Construction Contract

This contract is also used for the construction of a new home and is very similar to the QC1. It differs from the QC1 in that it only allows for limited variations and does not contain clauses for provisional and prime cost allowances or a clause for unforeseen circumstances. This contract should only be used where the builder is fully aware of the relevant site conditions and building restrictions.

QC3 Alteration, Addition and Renovation Contract

This contract is suitable for work including alterations, additions, or renovations to a home, or where the work to be performed is less than the construction of a new home such as building from base stage to fixing stage only. This contract is similar in format to the QC1 contract and contains detailed schedules, general conditions and a Contract Information Statement.

Qld Small Works Contract

This contract is suitable for domestic building work valued at less than $20,000 that does not affect the foundations or slab of an existing building or require engineered footings or foundations. It can be used for smaller alterations and renovation projects such as internal fit outs. If the work is valued at more than $20,000 or requires foundations data, the QC3 contract is the appropriate contract to use.

Qld Kitchen, Bathroom and Laundry – Supply and Install Contract

This contract is suitable for the supply and installation of kitchens, bathrooms and laundries and may also be used for other projects where there is a need to fabricate components off-site prior to installation. The contract includes clauses dealing with sample products and variances in natural materials. The contract also has a building period that starts from the date of installation to allow for prior fabrication off site.

Project Trade Contract

This contract is for use between principals (builders) and trade contractors (subcontractors) and sets out the terms and conditions that relate to the performance and completion of trade work. This contract is to be used where a subcontractor is only engaged for a single project.

Period Trade Contract Condition

This trade contract is identical to the project trade contract except it is designed to reduce paperwork where you have an ongoing relationship with a subcontractor or multiple jobs over a period of time. The contract allows for negotiation on the period that the contract runs and the length of the defects liability period. The contract conditions are to be used in conjunction with a Work Order. The Work Order sets out the details for each job, including a description and cost of the work. The conditions in the contract then apply to the job.

Work Order

This is for use with the HIA Period Trade Contract. It can be used to order trade works, request a quote for trade works or to confirm an order placed for trade works.

The terms and conditions set out in the domestic building contract referred to in this Information Sheet may not be suitable for every project. HIA does not make any representation as to the suitability of the terms and conditions for any particular project. Users of these contracts must make their own assessment (or seek professional advice) as to the appropriateness of the terms and conditions for any work or any changes that may need to be made to the terms and conditions.
