Английская Википедия:Australian Construction Contracts
Australian Construction Contracts govern how the parties to a construction contract behave and how the project manager and the contract manager administer the relationship between the parties.[1] There are several popular standard forms of construction contracts that are currently used in Australia.
Forms of Contract
Australian Building Industry Contract – ABIC MW-1 – Major works contract
- General
This contract has been developed jointly by the Royal Australian Institute of Architects and the Master Builders Australia Inc. and supersedes the Joint Contracts Committee (JCC) contracts, which are now withdrawn. It claims to use plain English and to involve less risk to architects than the ABS contract. It is recommended for use on building works of a major nature ($250,000 to $25million) where an architect is engaged to administer the contract. In its present form it does not appear to have any advantages over the ABS contracts.Шаблон:Opinion
- Variations
A maximum percentage for the Contractor's overheads and profit is nominated in Schedule 1 of the contract and is applied to the value of variations (additions and omissions)
- Provisional Sums
A percentage nominated in Schedule 1 of the contract is applied to the difference between the provisional sum and the cost of performance of the work. In the case where the performance of the work cost is more than the provisional sum, a percentage nominated in Schedule 1 of the contract is added to the difference and the resultant is added to the contract sum. Where the performance of the work cost is less than the provisional, the difference is deducted from the contract sum
- Failure To Pay
The rate of interest to be applied to contractually outstanding payments is nominated in Schedule 1.
- Reimbursement as a result of a delay in the progress of the works
The contract allows for reimbursement for causes of delay listed in clause L1.1 clause 1 to 13. This provision therefore provides reimbursement to the builder even though the cause of delay was not a breach of contract on the part of the proprietor. Where the delay is caused by breach on the part of the proprietor, the builder is entitled to recover damages sustained and incurred.
Australian Building Industry Contract – SW-1
- General
This contract is similar to MW-1 but is intended for use on building works from A$50,000 to A$3million.
General Conditions of Contract – National Public Works Conference Edition 3
- General
Issued by the Department of Administrative Services – Australian Construction Services, these conditions are still in use by some of the Public Works Departments in all states.
- Variations
Where the variation is valued by applying bill or schedule rates, no percentage is added. Where daywork rates are applied an agreed charge to cover overheads, administrative costs, site supervision, establishment costs, attendance and profit is made.
- Provisional Sums
No allowance is made on account of profit to or attendance on the adjustment of provisional sums.
- Failure To Pay
No mention of an interest rate is made.
- Reimbursement as a result of a delay in the progress of the works
No reimbursement is allowed unless the cause of the delay was due to any breach of the provisions of the contract by or any other act or omission on the part of the Principal, etc.
Australian Standard General Conditions of Contract AS4000
- General
This document updates AS2124-1992 to cater for changes in construction practice and law and the AS4000 series of documents are probably the most widely used in major works.
- Variations
Variations are valued by the superintendent using rates or prices in the contract. Where the bill of quantities or schedule of rates is not a contract document the rates shall still apply. No percentage is added to or deducted from the rates, but variations of omission include profit but not overheads. As overheads are not defined in the conditions it is common to accept the preliminaries on the overheads.
- Provisional Sums
A percentage nominated in the Annexure is applied to the amount actually paid for each provisional sum and can therefore result in an increase or decrease in the contract sum depending on whether the actual amount was more or less than the provisional allowance.
- Failure To Pay
The rate of interest is stated in the Annexure.
- Reimbursement as a result of a delay in the progress of the works
Reimbursement applies to compensable causes which are stated and can be expanded by completing the appropriate item in the Appendix.

- Failure To Pay
The rate of interest is stated in the Appendix.
- Reimbursement as a result of a delay in the progress of the works
Reimbursement is allowable only for certain causes of delay and for example inclement weather, although a cause for time extension, is not a cause with attracts time extension costs.

The percentages stated in the Contract Particulars are added to the value calculated. The percentages are also to be applied where a reasonable amount is agreed or determined. In agreeing or determining the reasonable amount, no mark-ups are to be included.

- Design development and construct – the Principal provides the Principal's project requirements together with a preliminary design;
- Design, Novate and Construct - the Principal provides the Principal's project requirements together with a preliminary design and requires selected sub-contractors to be novated to the Contractor.

As overheads are not defined in the conditions it is common to accept the preliminaries on the overheads.

- Failure To Pay
The rate of interest is stated in the Annexure.
- Reimbursement as a result of a delay in the progress of the works
Reimbursement applies to time extensions resulting from delay or disruption caused by Principal, Superintendent and their employees etc. Any other events for which costs for delay or disruption are payable must be shown in the Annexure.
Construction Management Agreement
- General
This agreement is for use where no head contractor exists and the owner pays to the manager a fee for his services. The agreement is issued by the Royal Institute of Architects (Victorian Chapter).
Liquidated Damages
Each set of contract conditions contains in its Annexure of Schedule a space for inserting a rate for liquidated damages. This rate is a genuine pre-estimate of damages that the owner will incur if the project is not completed by the authorised date for completion. Once contractually accepted the rate will apply whether the actual damages are higher or lower than the pre-estimate. Liquidated damages are always calculated on calendar days.
Liquidated Damages may be capped at a percentage of the contract sum. It is normal for Australian construction contractors to seek liability relief by trying to introduce a cap on Liquidated Damages, typically 10% of the contract sum.
