Builders Risk Insurance for Data Center Construction: A Complete Guide for 2026
By the NextGuard Insurance Specialty Team — May 2026
A 200 MW hyperscale campus has more moving parts than most commercial buildings ever will. Substations, switchgear, server hall fit-outs, liquid cooling loops, generator yards, fiber backbones — all coming together on a schedule measured in months, not years. The capital exposure is enormous, and the risk profile during construction is genuinely different from any other commercial real estate class.
That's exactly the gap that builders risk insurance is supposed to fill. But standard builders risk policies were not designed for modern data center construction, and that mismatch is one of the most expensive coverage gaps we see in the market.
If you're an owner, EPC contractor, or developer about to break ground — or you're managing a multi-phase campus already mid-build — this guide will walk you through exactly what data center builders risk insurance should cover, where the typical gaps sit, and how to structure your program for the realities of 2026.
For a broader view of the seven biggest gaps in data center coverage, start with our cornerstone post: Data Center Insurance: 7 Costly Coverage Gaps in Hyperscale and Colocation Programs.
What Is Builders Risk Insurance for a Data Center?
Builders risk insurance — sometimes called course of construction (COC) insurance — is a specialty property policy that covers a project during the construction and commissioning phase. For a data center, it protects:
The building structure under construction
Materials, fixtures, and equipment on-site, in transit, or at temporary storage
Major specialty equipment (generators, switchgear, transformers, chillers)
Soft costs and revenue loss from covered delays
The work itself, including testing and commissioning operations
The coverage starts when site work begins (typically with the foundation pour) and continues until the facility is fully operational, at which point it transitions to operational property insurance.
For a typical commercial building, this transition is straightforward. For a data center, it's anything but. Hyperscale and large colocation projects often have multiple halls in different stages — one fully commissioned, one mid-fit-out, one still in steel — all within the same campus and often under the same insurance tower.
Getting that transition right is the entire ballgame.
What a Modern Data Center Builders Risk Policy Should Cover
There are five coverage components that should be non-negotiable in any data center builders risk program in 2026.
1. The Hard Construction Cost (Materials, Equipment, and Workmanship)
This is the foundational coverage — physical loss to the structure, materials, and equipment from a covered cause of loss. Look for an all-risk form (excludes only what is specifically named) rather than a named-perils form (covers only what is specifically listed). All-risk forms are standard in modern data center programs and significantly broader.
What to verify:
Coverage extends to mechanical, electrical, and plumbing (MEP) systems during installation
Specialty equipment — generators, switchgear, transformers, UPS systems — has dedicated sublimits sized to current replacement cost
Materials in transit and at off-site storage locations are covered (especially important for long-lead-time equipment held at the manufacturer's facility)
Resulting damage from defective workmanship or design is covered, even if the underlying flaw isn't
2. Delay in Startup (DSU) Coverage
This is where most builders risk programs fall down for data centers.
Delay in startup coverage — sometimes called advance loss of profits (ALOP) — replaces the income or contractual revenue you would have earned if the project had completed on schedule, when a covered loss pushes the go-live date.
For a hyperscale campus, every week of delay can represent millions in lost revenue, deferred tenant move-ins, or contractual penalties. Without DSU, that exposure sits entirely on the developer's balance sheet.
What a properly structured DSU should include:
A period of indemnity that runs from the original scheduled completion date through the actual completion date — at least 12 months for most data center builds
A waiting period short enough to be useful (14–30 days, not 60–90)
Coverage for fixed costs that continue during delay (debt service, salaries, utilities, leases)
Coverage for lost revenue at the originally projected rate
3. Soft Costs
Even with DSU in place, a covered delay creates a long list of incremental expenses that aren't captured by lost revenue alone. Soft cost coverage picks those up.
Specifically, look for soft cost coverage that includes:
Architect, engineering, and consultant fees during the extended period
Legal and professional fees connected to the delay
Permit fees and inspection costs that have to be re-incurred
Additional financing costs (loan extension fees, increased interest)
Marketing and tenant attraction costs that have to be re-spent
For a $1B campus, soft costs can run into eight figures during a multi-month delay. They are not optional in modern data center construction insurance.
4. Commissioning and Hot/Cold Testing
Here's the language hand-grenade that quietly disqualifies a lot of standard builders risk forms: the commissioning and testing exclusion.
Many off-the-shelf policies exclude — or sharply limit — coverage during commissioning, hot testing, and cold testing. The logic is that during testing, the facility is "not yet a building" but "not yet operating," so traditional underwriters don't want to take that exposure.
The problem is that commissioning is the single most failure-prone phase of a data center build. It's when you load the systems, energize the switchgear, and run the cooling loops at production-equivalent loads for the first time. If something is going to fail, this is when.
Your policy should:
Explicitly include commissioning, hot testing, and cold testing as covered operations
Not exclude consequential damage caused by testing-related failures
Coordinate with your operational property tower so there's no gap between handover phases
Cover the IT and tenant equipment during testing, not just the building systems
5. The Operational Transition
The single biggest claims dispute we see in data center builders risk involves the transition from construction to operations. A property is substantially complete but not yet fully operational. One hall is live; an adjacent hall is mid-test. The builders risk underwriter says that hall isn't covered anymore. The operational underwriter says it's not on cover yet. The owner is exposed, sometimes for tens of millions, in the most fragile window of the entire build.
The fix is a documented, written transition plan that everyone — owner, broker, builders risk carrier, and operational carrier — has signed off on before the first piece of equipment goes live. Specifically:
A defined trigger for when each phase of the project moves from builders risk to operational coverage (substantial completion, certificate of occupancy, first paying tenant, etc.)
An overlap window where both policies are in force, eliminating the risk of a gap
Coordinated indemnity periods so DSU and operational BI don't double up or leave a gap
Pre-agreement on which carrier responds for which type of loss during the overlap
If you can't show this on a single page to your CFO, you have a transition risk problem.
Common Data Center Builders Risk Mistakes (and How to Avoid Them)
Across the placements we audit, the same mistakes show up over and over. Here are the four that cost the most.
Mistake 1: Assuming the EPC's policy is enough. EPC contractors typically carry their own builders risk for the contract value, but that policy is structured around their interests — not yours as the owner. It rarely includes adequate DSU, soft costs, or coverage for owner-furnished equipment. Buy your own owner-controlled builders risk on top of (or in lieu of) the EPC's program.
Mistake 2: Using the construction contract value as the policy limit. Modern data centers have material values that escalate during construction. Steel, copper, and specialty equipment prices have all moved sharply since 2022. A policy limit set at original contract value can be 15–25% short of replacement cost by the time a loss occurs. Build in escalation clauses or revisit limits at each major milestone.
Mistake 3: Buying "named-perils" instead of "all-risk." Named-perils forms still exist in the market, and they're cheaper. They're also almost always inadequate for a data center build. The exposure profile is too varied — water, mechanical breakdown, theft, vandalism, transit damage, weather — to rely on a list. All-risk is the standard.
Mistake 4: Treating commissioning as an afterthought. We covered this above, but it bears repeating: commissioning is when most things actually break. Make sure your policy treats it as a covered phase, not an excluded one.
How Much Does Builders Risk Insurance Cost for a Data Center?
Cost varies based on a number of factors, but rough benchmarks for a properly structured program:
Hard construction cost rate: typically 15–35 basis points of the total insured value, depending on geography, project complexity, and carrier panel
DSU and soft costs: add 30–60% to the hard construction cost premium, depending on the indemnity period and limits
Total all-in: usually 0.25%–0.50% of total project cost for a well-structured program
The variance is wide because the underlying risk varies wide. A greenfield site in a stable jurisdiction with experienced contractors and a clean schedule is fundamentally different from a brownfield retrofit in a hurricane zone with an aggressive go-live date. The premium that matters is the one that buys the right structure — not the cheapest one.

Frequently Asked Questions
What is builders risk insurance for a data center?
Builders risk insurance — also called course of construction insurance — is a specialty property policy covering a data center facility while it's under construction and commissioning. It protects the structure, materials, equipment, and (with proper endorsements) lost revenue and soft costs caused by a covered delay.
Does builders risk cover the commissioning phase of a data center?
It should — but many off-the-shelf forms exclude or limit coverage during commissioning, hot testing, and cold testing. Because commissioning is the single most failure-prone phase of a data center build, your policy should explicitly include these phases as covered operations, with clear consequential damage language.
What is delay in startup (DSU) coverage and why do data centers need it?
DSU coverage replaces the revenue or contractually-agreed income a developer would have earned if the project had completed on schedule, when a covered loss pushes the go-live date. For data centers — where every week of delay can mean millions in deferred tenant revenue or penalty exposure — DSU is essentially non-negotiable in a properly-structured builders risk program.
How long does builders risk insurance last on a data center build?
Coverage typically begins when site work starts and continues through full commissioning of the facility. For multi-phase hyperscale campuses, the policy may run for several years and include written transition rules for each hall as it moves from builders risk to operational property.
Should the owner or the EPC contractor buy builders risk?
Owners should generally carry their own owner-controlled builders risk policy. EPC contractors often have a builders risk policy structured around their own interests — typically without adequate DSU, soft costs, or coverage for owner-furnished equipment.
How much builders risk insurance do I need for a data center?
The policy limit should equal the full replacement cost of the project at completion, not the original contract value. Materials, equipment, and labor costs can escalate during a multi-year build, so include explicit escalation clauses or revisit the limit at each major milestone.
