How Early Insurance Planning Cut Costs on a Major Tasmanian Build

The project is not a routine build. Stage 1 construction is due to commence in 2026 and includes 129 kilometres of double-circuit transmission lines, 278 new towers, three major substation upgrades and extensive engagement with private landholders. As part of the broader Project Marinus program, it sits within a nationally significant energy transition pipeline where insurable risks, lender expectations and delivery milestones are tightly connected.

For builders, civil contractors and infrastructure participants, the key point is not simply the headline saving. It is how that saving was achieved. Early appointment gave the adviser time to understand the risk profile, project finance structure, contractual allocation and stakeholder requirements before the insurance programme was locked into procurement constraints. In a financed project, contract works, public and products liability, delay in start-up and related covers are not just administrative requirements. They help support bankability.

This matters because the Australian construction insurance market is not moving as one uniform cycle. Some classes have softened, creating opportunities for better pricing, while specialist areas such as complex infrastructure, energy transmission and subsea works can still face tighter capacity and longer placement processes. A stronger submission, supported by credible project data and clear risk controls, can make a substantial difference when insurers are deciding how much capacity to deploy and on what terms.

The TasNetworks example also shows why engaging a broker late can create a structural disadvantage. By the time tenders, lender requirements and major contracts are settled, many insurance decisions have effectively already been made. Early input can help project teams identify which risks should be retained, transferred, insured or managed through contingency planning.

• Review insurance requirements at feasibility or planning stage, not just before contract execution.
• Align insurance limits and policy wording with lender, principal and subcontractor obligations.
• Maintain detailed risk data on safety systems, timelines, site exposure and supply chain dependencies.
• Track construction insurance market updates so procurement assumptions remain current.

For mid-sized contractors, the lesson scales down as well as up. Even where a project does not involve national infrastructure or government-backed finance, early insurance planning can reduce surprises, improve negotiating leverage and protect margins. In a sector already dealing with cost pressure, delay exposure and regulatory scrutiny, treating insurance as part of the project strategy may be one of the more practical ways to preserve both cash flow and project confidence.
