Rising Construction Projects Driving Changes in Insurance Requirements

Global construction projects are on the rise, with industry valuation expected to surge from $16 trillion in 2025 to $22 trillion by 2030. This growth is largely driven by data center developments, green energy investments, and the need for resilient infrastructure. According to Aon, these changes are reshaping insurance requirements across property, professional liability, casualty, and surety lines. Regional variations in market conditions, project types, and risk classes are significant, with insurers fiercely competing for low-loss accounts while scrutinizing higher-risk sectors.

The construction property insurance markets have stabilized following a year with fewer natural disasters in 2025. However, exposure to natural catastrophes still impacts coverage availability and pricing, particularly in regions with high hazard indexes. Economic losses from natural disasters were reported at $260 billion in 2025, with the U.S. accounting for nearly 55% of these losses. Severe weather and wildfires were the principal contributors domestically, while Europe and the Asia-Pacific region experienced major storms, earthquakes, and floods.

In the U.S., insurance capacity and pricing for windstorms, floods, and earthquakes remain stable. However, limits are tightening and deductibles are increasing for wildfire and convective storm risks in high-risk zones. Water damage is the leading cause of losses in standard building construction. As a result, insurers prefer a quota-share approach, limiting participation to 35% in high-value projects.

Data center construction is booming, with valuations climbing and the integration of dedicated power facilities becoming a standard. Future projections estimate $3 trillion in global data center investments by 2030, considering small modular reactors as viable power sources. The U.S. construction casualty market is diverging, with auto liability and physical damage rate increases challenging insurer profitability, notably in California, Florida, and Texas. General liability remains stable for commercial non-residential construction, but tighter conditions are present for heavy civil works and residential projects.

There is a notable reduction in available capacity in excess liability markets due to large settlements. Insurers are pulling back from offering substantial excess layers, with lead excess limits shrinking from $8-10 million to about $5 million for major civil projects. Professional liability markets face pressure from rising claims severity, inflated defense costs, and significant verdicts. Insurers are increasing retentions, especially for loss-affected accounts, while project-specific coverage remains costly.

The global surety market is projected to grow by around 5% annually, potentially reaching $33 billion by 2032, driven by large infrastructure projects in North America. However, 2025 saw credit issues in the mid-market construction sector, leading to higher instances of nonpayments and defaults, which are expected to worsen. The renewable sector also faces challenges due to regulatory changes affecting project feasibility.

Hospitals encounter a challenging liability landscape, with frequent large legal verdicts threatening their viability. Insurers providing hospital liability coverage are confronted with increasing claims costs and restricted capacity in high-risk areas. To secure competitive insurance terms, hospitals must focus on enhanced risk management and proactive claims handling. Emphasizing improved risk management practices and litigation awareness is vital for minimizing insurance costs and enhancing underwriting profiles in this evolving liability environment.
