Monter le contrat sur AS 4000 ou AS 2124

Create the contract record naming the form, AS 4000-1997 or AS 2124-1992, the contract sum and whether it is lump sum or schedule of rates, and enter the Annexure values that the rest of the job runs on. Record the principal's amendments as amendments rather than folding them into the printed clause, so anyone reading later can see what was changed from the standard.

Pourquoi: The commonest cause of an argument on an Australian Standard contract is two people reading two different documents, one the printed form and one the amended version. A contract record that names the form, carries the Annexure and lists the departures is what makes a clause reference a fact rather than an opinion.

Record what security the contract takes, cash retention held from each progress payment or unconditional undertakings from a bank, the percentage and the limit, and the two events that release it: the reduction at practical completion and the release at the end of the defects liability period. Note who holds the guarantees and where.

Pourquoi: Security is the cheapest money on the job to lose track of, because nobody chases it until long after the site has closed and the people who knew the arrangement have moved on. A reduction that should have happened at practical completion and did not is working capital sitting in somebody else's account for a year.

Name the Superintendent and the Superintendent's Representative, and build the approval route that says which decisions they make alone, which need the principal, and what value threshold moves a direction from one to the other. Certificates, directions to vary and extensions of time all sit on that map.

Pourquoi: Both forms require the Superintendent to act honestly and, for the functions where they are certifying rather than acting as the principal's agent, reasonably and independently. A route that records who decided what and on what authority protects the certifier as much as the contractor, because a direction given by someone without the authority to give it is an argument waiting for the final account.

Put the date for practical completion, the separable portions if the contract has them, the liquidated damages rate and any limit on it, and the length of the defects liability period under watch, together with the time the Annexure allows for a claim to be made. Let each one warn before it lands.

Pourquoi: Liquidated damages run per day from a date, and the defects liability period ends on a date, and both are worked out from Annexure entries that nobody rereads once the job starts. A claim window that closed while the site was busy is an entitlement gone, and no notice is served on you when it happens.

Take the allocations out of the conditions and the Annexure and put them on the risk register in words a site manager can act on: latent conditions and what counts as one, who effects the works insurance and the public liability cover and for how much, the excepted risks, and where the contract has been amended to move a risk from the standard position.

Pourquoi: Latent conditions are the clause most often amended away in Australian practice, and a contractor who assumed the standard position and priced accordingly finds out the day the excavator hits rock. A risk that lives only in clause 25 of a document in a drawer is a risk nobody manages.

Send the complete set for execution, conditions, Annexure, amendments, drawings and specification listed as contract documents in the order of precedence the contract sets, and keep the executed version as the one the site, the estimator and the accounts all work from.

Pourquoi: Work starting before execution is normal in Australia and it is also how a job runs for six months on a draft nobody signed. The order of precedence matters as much as the signature, because it decides which document wins when the drawing and the specification disagree, and they always disagree eventually.
