Marsh Risk, a business of broker Marsh, announced the launch of Nimbus Casualty, a new insurance facility providing clients with excess general liability protection during the construction phase of their U.S.-based digital infrastructure projects.

The facility offers up to $75 million in capacity, with a minimum attachment point of $25 million and is supported by a panel of “A+”-rated Lloyd’s and London insurers. Leveraging Marsh Risk’s proprietary XSellence excess casualty form, Nimbus Casualty delivers follow-form coverage across a client’s excess casualty program, enhancing coverage certainty and streamlining claims negotiation.

The launch of Nimbus Casualty follows the recent expansion of Marsh Risk’s market-leading large-scale data center construction insurance facility Nimbus, which offers up to $2.7 billion in limits of traditional construction all-risks, delay in start-up, property damage, and business interruption cover.

“The U.S. casualty market presents increasing complexity and challenges, especially for digital infrastructure clients managing large-scale, high-value projects with long-term liability exposures,” said Paul Woodward, Head of Casualty, Marsh Risk International Placement. “With Nimbus Casualty, we combine Marsh Risk’s market-leading construction expertise with our market-leading excess casualty form to provide clients with the advice and coverage certainty they need to efficiently safeguard their digital infrastructure investments.”
