Case Study: Surge Cover for a Western Suburbs Builder During Peak Demand

Details have been generalised and client information withheld at their request.

The situation

A residential and light commercial builder based in Melbourne's western suburbs had a problem most builders would welcome — they'd won three concurrent projects in a six-week window. Two townhouse developments and a commercial fit-out, all in the Wyndham Vale and Hoppers Crossing area.

The problem wasn't winning the work. It was running it. Their internal back office — one project coordinator and an estimator shared between all three jobs — couldn't scale fast enough to maintain proper cost oversight, variation management, and subcontractor invoice review across all three projects at once.

The builder's principal had been absorbing the administration load personally, on top of site responsibilities. By week four, it was clear something had to give.

What was needed

The immediate requirements were:

• A cost plan update for each of the three projects, incorporating approved variations and current subcontractor commitments
• A variation register for each project, bringing all informally approved variations into a single documented record
• Subcontractor invoice review for the next payment cycle across all three jobs
• A weekly review call to keep the builder's team informed on cost position

There was no time for a lengthy onboarding process. The next payment cycle was twelve days away.

How we approached it

Engagement was structured as a fixed-term project oversight retainer across all three projects, with a clearly defined scope and a documented deliverables schedule.

The first two days were spent on-site and in the builder's office — reviewing existing cost plans, interviewing the project coordinator, and working through the variation history across all three projects. Several variations that had been instructed verbally were identified, reconstructed from email and site supervisor notes, and brought into the variation registers.

By day three, we had a working cost plan and variation register for each project. The builder could see, for the first time in several weeks, their actual cost position on each job.

The payment cycle

The subcontractor invoice review for the payment cycle identified two invoices that overstated claimed progress against actual site observations. Both were adjusted before payment was certified. The combined reduction was modest — but the precedent of a structured review process had been established, and the subcontractors knew it.

The outcome

The three-project engagement ran for fourteen weeks. By the time the builder's internal capacity had caught up with the workload, all three projects had current cost plans, documented variation registers, and a payment administration process that the coordinator could maintain independently.

One of the townhouse projects required an EOT claim due to a subcontractor-caused delay on structural framing. The documentation maintained during the engagement period provided the record needed to support the claim.

The commercial fit-out delivered within 2% of the original contract sum.
