conditions of contract, published by Standards Australia, 1992. Commonwealth of Australia.

Read the full text from Standards Australia. This page holds the obligations in it, not the document.

The elderly relative of the family. Fondly regarded, universally known, and perfectly literal. It will take your entire extension of time over one late notice and consider it fair, and it has not changed its mind about anything since 1992.

3 obligations, clause by clause.

Three obligations transcribed, read from the clause text and one secondary source. Where a row came from a secondary source, the table says so.

Watch AS 2124-1992 on your own jobs.

A clause in the table turns on a fact your jobs already record: a date, a notice, a record kept. Demiton reads that fact from the register and tells the person who signs off before the window shuts. Missing one costs what the If missed column says.

AS 2124-1992 and AS 4000-1997, on the three obligations that decide most claims.

Both clauses are in the library, so the comparison is the clause text rather than an opinion about it.

On	AS 2124-1992	AS 4000-1997
Extension of time claim	cl 35.5: within 28 days of the delay starting. Barred if missed.	cl 34.2, 34.3, 34.5: within 28 days. Barred if missed, and the Superintendent has 28 days to decide or the extension is deemed granted.
Variation claim	cl 46.1: written notice within 28 days. Barred. 42 days applies to extra cost from a direction or approval.	cl 41.1-41.3: particulars within 28 days, and cl 41.2 says a missed notice shall neither bar nor invalidate the claim. Damages only.
Latent condition notice	cl 12.2, 12.4: notice forthwith. No day count stated.	cl 25.2, 25.3: notice promptly. 28 days is the cost cut-off, not the notice window.
What that means in practice	The harder form. A late variation notice can bar the claim outright.	The softer form unamended. Principals' amendments routinely add the hard bar back, so read the special conditions, not the cover.

What this page is, and is not.

It is the clause text this library holds for this document, with the window and the consequence. It is not legal advice, and it is not a substitute for reading the document you signed.

No library of law is complete, and Demiton never says this one is. An obligation the library does not hold, and you did not add, is not protected. You can add your own to any job.
