Notice deadline & draft

Calculate a notice deadline and prepare a structured first draft.

There is no universal Construction Act notice period for delay or change notices. Enter the exact clause period. For statutory suspension following non-payment, section 112 requires at least 7 days’ notice after the final date has passed, but the contract and service rules still need checking.

How to Use This Notice Builder

Start with the event or awareness date and the notice period in the signed contract. Choose calendar or working days only as the clause requires. Complete the project, sender, recipient, event, effect and action fields. Add the clause reference, contractual service method and evidence references before reviewing the draft.

Worked Example

In an illustration using a seven-calendar-day period after 1 October 2026, the calculated deadline is 8 October 2026. This illustrates the inputs only; the applicable trigger and counting rule come from the contract.

Before You Use the Result

The button prepares a working draft; it does not send a notice. Check the recipient, address, authority and method of service before issue, and keep proof of delivery with the exact document sent.

For a project that needs a wider review, explore QSEC procurement and contract advice alongside The Subbie QS support.
