There are 2 common standard form contracts used in the commercial construction contracts
AS 2124 and AS 2545, published by Standards Australia and written by a committee of construction industry representatives. These contracts deal with a host of the usual reasons for disputation in the commercial construction industry including: retention, performance, termination, provisional sums, latent conditions, progress & schedule of works, suspension, delay, variations, payment.
The standard form contract AS 2124 is however the most commonly used contract as between developer/principal and builder. When this is used then the standard form contract AS 2545 should be used between builder and subcontractor.
