The Situation

A Victorian geotechnical consultant had been working on some of Australia's largest infrastructure projects - tunnelling works and metropolitan rail builds. Their revenue was modest relative to the project values they were advising on, but insurers don't price geotechnical PI based on revenue alone. The aggregate exposure from megaproject involvement was the key pricing driver.

02

Our Approach

We went to specialist engineering PI markets that understand infrastructure work. The submission detailed the specific nature of the geotechnical consultancy - soil and rock analysis, foundation design recommendations, site investigation - and clearly delineated between advisory work and any construction activities. We provided project lists to demonstrate the scope.

03

Challenges

The main challenge wasn't getting cover - it was the price. When geotechnical engineers work on projects worth hundreds of millions or billions, the potential liability from a geotechnical error is enormous. Foundation failures, tunnel collapses, soil instability during construction - the consequences are catastrophic and the claims are massive. Insurers price accordingly, regardless of the consultant's own revenue.

04

The Outcome

Terms were obtained from specialist markets at over $100,000 for $5M PI. That's a significant premium, but for the level of exposure involved, it reflects the genuine risk. The consultant understood that megaproject work commands megaproject premiums. The alternative - being uninsured or underinsured on a landmark project - wasn't an option.

Broker Insight

If you're a geotechnical engineer working on major infrastructure, don't be surprised by high PI premiums. The insurer isn't looking at your revenue - they're looking at what happens if your soil report is wrong and a $2 billion tunnel project has foundation issues. That said, not all insurers price megaproject exposure the same way. Shopping the market through a broker who understands engineering risk can still save you tens of thousands.

QUESTIONS

Related Questions

Insurers price PI based on potential claim size, not just revenue. A geotechnical error on a major tunnelling or rail project could result in claims worth tens or hundreds of millions. The premium reflects that exposure, even if your consulting fees are a small fraction of the total project value.
To some extent, yes. Maintaining a clean claims history, clearly scoping your engagement letters, and using appropriate limitations of liability can help. But if you're working on megaprojects, the base premium will always reflect the project exposure. Learn more about geotech insurance.
