Data Center Construction Insurance: Covering the Risks of High-Tech Builds in 2026

Why Data Center Construction Requires Specialized Insurance

Data center construction is one of the fastest-growing segments in the U.S. construction market. According to CBRE Research, data center construction starts increased 70 percent between 2022 and 2024, driven by artificial intelligence infrastructure buildout and cloud computing expansion. General contractors and specialty trades working on these projects face exposures that standard construction insurance programs are not designed to address.

A contractor who builds office buildings or multifamily residential properties and attempts to apply the same insurance program to a data center project will discover significant coverage gaps at the worst possible time - after a loss has occurred. Data center clients are sophisticated, contractually demanding, and fully prepared to pursue uncovered losses against contractors who lack adequate coverage.

The Unique Exposures of Data Center Construction

High-Value Equipment Installation Liability

Data centers contain extraordinarily valuable equipment - server racks, cooling systems, uninterruptible power supplies, and network infrastructure that can cost tens of millions of dollars per facility. Contractors working in active or partially operational data centers risk damaging this equipment during construction activity. A dropped tool, a water leak from plumbing work, or an accidental power interruption during electrical installation can damage equipment worth hundreds of thousands of dollars.

Standard commercial general liability policies frequently contain exclusions for damage to property in the contractor's care, custody, or control - which is precisely the situation when a contractor is working in proximity to installed equipment. Specialized inland marine coverage for installation and contractors professional liability must be secured before any work begins in a facility containing operational equipment.

Electronic Data Exclusions in Standard GL Policies

Most commercial general liability policies contain an exclusion for loss of electronic data. For a data center project, this exclusion is significant. If a contractor's operations cause the loss or corruption of data stored on a client's systems - for example, through an accidental power disruption - the resulting data loss claim may be entirely excluded from the contractor's GL policy. Contractors working on data center projects should request a manuscript endorsement removing or modifying the electronic data exclusion, or secure a technology contractor's professional liability policy that covers this exposure.

Builders Risk Complexity

Standard builders risk policies cover the structure under construction against physical loss. For data center projects, the builders risk program must be carefully structured to address several additional complexities:

• Coverage for high-value mechanical and electrical systems installed early in the construction process, which may be valued at multiples of the structural cost
• Testing and commissioning coverage, which addresses losses that occur when newly installed systems are powered on and tested - a period of elevated risk that many standard builders risk policies exclude or sublimit
• Delay in completion coverage that accounts for contractual SLA obligations and the extraordinary revenue losses a data center client suffers from a delayed opening
• Transit coverage for equipment being delivered to the site, which may involve millions of dollars of servers and networking equipment moving from manufacturers to the project site

Cyber Liability Exposure During Construction

Data center projects increasingly involve contractors accessing operational systems and networks during construction. A mechanical or electrical contractor connecting to building management systems, a security contractor installing access control systems, or an IT contractor performing network infrastructure work all represent potential cyber attack vectors. The 2023 Verizon Data Breach Investigations Report found that third-party vendor access was a contributing factor in 15 percent of data breaches - and construction contractors represent exactly this type of third-party access risk.

Contractors working on data center projects should carry cyber liability coverage that includes third-party coverage for data breaches caused by the contractor's systems or personnel. Some data center clients now require evidence of contractor cyber liability coverage as a condition of the construction contract.

Professional Liability for Design-Build Components

Many modern data center projects involve design-build delivery, where the general contractor takes responsibility for both design and construction. When a contractor assumes design responsibility - even partially - the contractor's professional liability exposure expands dramatically. A design error in a data center cooling system that results in equipment damage or operational downtime can produce claims far in excess of standard GL limits. Contractors performing any design-build function on data center projects need contractors professional liability coverage that specifically covers technology infrastructure design.

Contract Requirements on Data Center Projects

Data center clients - hyperscalers, colocation operators, and enterprise end users - have among the most demanding insurance requirement schedules in the construction industry. Contractors bidding data center work should expect to see:

• Commercial general liability limits of $5,000,000 per occurrence and $10,000,000 aggregate - significantly above standard commercial construction requirements
• Umbrella or excess liability of $25,000,000 to $50,000,000
• Builders risk coverage with equipment and testing coverage specifically addressed
• Professional liability for any design-build components with limits of $5,000,000 or higher
• Pollution liability covering refrigerant releases from cooling system work
• Cyber liability in amounts of $5,000,000 or higher
• Additional insured status for the owner, developer, and multiple upstream parties
