There is a moment in every data center development that is consistently underestimated. It isn't groundbreaking day and it isn't when the last server is installed. It's the sequence of "ready for service" (RFS) dates, when assets move from contractor control to developer ownership, often while construction is still active on adjacent phases.
At each of the transition points, the insurance program shifts. Coverage that applied one day may not respond the same way the next. Decisions that determine whether that transition is protected are typically made six to nine months earlier, before construction contracts are finalized.
In our experience advising data center developers, operators and private equity investors, five recurring insurance gaps emerge during handover. These gaps are predictable and avoidable, but they can be costly when overlooked.
1. The ownership transfer gap
Under most construction programs, project work sits in the care, custody and control of the contractor. The contractor's All Risks policy responds accordingly. At each RFS milestone, however, a portion of the facility transfers to the developer and begins operating under a different risk profile.
The challenge is that many construction programs aren't designed to seamlessly extend operational property coverage on a phased basis. At the same time, operational property programs are often not activated until final handover. This creates a period where a partially operational facility may be generating revenue without fully aligned insurance coverage.
Risk exposure during this period is elevated. Construction activity continues alongside live operations, increasing the likelihood of damage, disruption, or cross-party liability affecting tenants and infrastructure.
Addressing this gap requires early planning. Developers should clearly define how coverage transitions at each RFS milestone, confirm which parties benefit from each policy and align subrogation provisions before the first handover occurs.
2. The SLA breach coverage illusion
When a data center begins hosting customers, Service Level Agreements (SLA) define availability thresholds, credit structures and in some cases, termination rights. Operators often assume their business interruption insurance will respond if SLAs are breached following a covered event.
In many cases, SLA credits and penalties are treated as contractual liabilities and may not be covered under standard insurance policies unless specifically addressed in the policy wording. While coverage can sometimes be negotiated or structured within an insurance program, it isn't typical in standard placements. This creates a protection gap that can be commercially significant for colocation operators, where service credits and step-in rights can materially affect asset value even when the underlying physical loss is modest.
As explored in our perspective on managing SLA liability in data center projects, aligning contractual exposure with structured risk transfer solutions can help stabilize cash flow and protect asset value across both development and operations.
3. The contractual liability cap mismatch
Construction contracts and operational agreements allocate risk differently. Indemnities and liability caps in construction contracts are designed for build-phase exposures. Operational agreements with tenants, utilities and service providers reflect a different set of risks.
At handover, these frameworks intersect. A contractor may be responsible for damage to a live facility, but their liability cap may not reflect operational exposure levels. At the same time, tenant losses may fall outside both the contractor's responsibility and the developer's operational insurance structure.
Insurers should pay close attention to these dynamics, especially at renewal following a handover. Questions often focus on how contractual liability was allocated and whether the insurance program responded appropriately.
Mitigating this risk requires a coordinated review of construction and operational contracts, with specific focus on how liabilities interact during phased handover. While this work sits outside placement, it directly determines whether coverage performs as intended.
4. The delay in start-up/operational BI disconnect
Delay in Start-Up (DSU) insurance protects against lost revenue during construction delays. Operational Business Interruption (BI) insurance applies after handover. In theory, these two coverages should connect seamlessly. In practice, they often don't.
A common issue arises when the operational BI indemnity period doesn't reflect the restoration assumptions used in DSU underwriting. For example, if DSU assumes a 12-month restoration period but operational BI only provides six months of coverage, the program leaves a significant exposure gap.
This is particularly important in data centers, where supply chains for specialized equipment are constrained. Lead times for critical components such as switchgear and cooling systems can extend from 12 to 24 months.
A program based on generic restoration assumptions will not adequately reflect these realities. Operational BI must be calibrated using the same data center-specific considerations applied during DSU underwriting.
The most effective approach is to align these coverages during the construction phase, rather than attempting to reconcile them after handover.
5. The operational wording mismatch
The final gap is often the most pervasive. Many developers transition from construction coverage to an operational property program derived from standard commercial or industrial wordings.
These forms were not designed for data centers.
Data centers operate on a power-dependent, availability-driven model. Localized equipment failure can impact thousands of servers. Cooling performance directly affects contractual delivery. Financial outcomes are closely tied to operational continuity.
Standard property wordings don't always account for these dynamics. Misalignment typically appears in several key areas:
