Source: SUMIT services, as at October 2026. Indicative: every project differs.
Step 01Contract award
The project, the contract, where it stands and what your team needs; a capacity check, then a scope and fee by the day or on retainer.
Step 02Contract award
Read the head contract, subcontracts, cost plan and records, then set up the notice regime, reporting and cost to complete.
Step 03Delivery
Procurement and package letting, variations and compensation events, notices, monthly cost reports and forecasts, inside your team or alongside it.
Step 04Completion and final account
Agree subcontract final accounts and prepare the head contract final account.
Step 05Post-completion
Registers, records and open items handed to your team so it can carry them on.

Guidance
What a site diary must capture, the five registers that preserve entitlement, programme, photo and cost record discipline, and how to run the evidence pack as a system with named owners and audits.
Guidance
What practical completion requires, how disputes over the certificate run, and how both sides should run the defects liability period through to the final certificate and the release of security.
Guidance
Written directions and the confirmation of oral ones under AS 4000, the Liebe v Molloy line for work done without them, the cl 36.4 pricing order, and the Court of Appeal's holding in Kaloriziko v Calibre [2025] NSWCA 259 that approving in-scope work as a variation does not make it one.
