Builders Risk for Industrial and Data Center Projects

Commissioning on an equipment-heavy project is a sequence, not a single event: factory acceptance testing at the manufacturer, setting and termination on site, cold checks, first energization, functional tests, then integrated systems testing where generators, switchgear, UPS and cooling run together under simulated load. Industrial plants add hot testing, where process equipment runs with feedstock, fuel or heat. Each stage carries more energy and more potential for damage than the one before.

Builders risk forms handle this in several ways. Some insure testing for a stated number of days after first energization. Some exclude hot testing unless it is scheduled. Many end coverage on any piece of equipment once it is accepted by the owner, even if the rest of the project is still under construction. The AIA exhibit asks the owner's policy to include building systems damaged during testing and startup, but a quote can still limit that, so compare the two documents.

ASHRAE Guideline 0 and Standard 202 describe a commissioning process built around the owner's project requirements, and many owners now require one. Share that commissioning plan with the underwriter early. It shows who controls each test, the sequence and the duration, which is what the testing clause needs to match.

When a transformer fails during energization or a weld fails on a process line, the first claim question is whether the cause was a defect in design, materials or workmanship. Builders risk forms answer with a defects clause. Many U.S. forms exclude the cost of making good the defective part while insuring resulting damage to other insured property. The AIA exhibit asks for insurance of ensuing loss from errors in design, workmanship or materials, which tracks that structure.

On larger industrial and energy projects, insurers often use London market defects wordings, including the London Engineering Group clauses, commonly called LEG 1, LEG 2 and LEG 3. They run from a narrow outright exclusion toward broader wording that pays more of the damaged property and excludes only the cost of improving the original design or workmanship. Treat any summary as a starting point: the actual clause, and how the policy defines damage, decides the claim. Ask which wording is quoted, whether a broader version is available for the testing period and how the premium and deductible change.

A data hall that misses its energization date can delay a tenant lease with significant rent at stake, and a plant that misses startup can lose a production season. Delay in startup coverage, sometimes called advance loss of profits, is written to respond to that lost revenue or added cost, typically only when the delay results from physical damage insured by the builders risk policy itself.

Underwriters price this from the critical path. They will ask which equipment has the longest replacement lead time, whether spares exist, how the lease or offtake agreement defines the commencement date and whether liquidated damages apply. Waiting periods are often longer than on ordinary soft cost coverage, and some insurers will not write delay for prototype or first-of-kind equipment. The limit, waiting period and indemnity period should come from the financial model rather than a default.

Large power transformers and similar equipment often move as permitted oversize or overweight loads. The Texas Department of Motor Vehicles issues a separate superheavy permit category for non-divisible loads above the standard permit weights, and Caltrans issues special transportation permits for loads exceeding California Vehicle Code limits, including variance permits for the widest and tallest loads. Those moves involve route surveys, escorts and rigging handoffs where damage is most likely.

Builders risk transit and off-site storage extensions often carry sublimits sized for ordinary materials. A single transformer may exceed that sublimit by itself. Decide whether transit is insured under the builders risk with a raised per-conveyance limit, under a separate cargo or project cargo policy or by the vendor until delivery. Match the answer to the purchase order's delivery terms. Ask how equipment stored at a third-party yard for months before installation is treated.

When the contractor moves equipment on its own trucks, see flatbed and heavy-haul truck coverage.

Data center campuses rarely finish at once. The first data hall may be energized and turned over to a tenant while later halls are still framed. Once a hall carries live load, construction risk and operating risk sit side by side, and federal construction safety rules require deenergized equipment and circuits to be rendered inoperative and tagged wherever they could be energized. Insurers want to see how the energized areas are separated from active work.

Ask how the policy treats each hall at energization: whether builders risk continues until tenant acceptance, ends at owner acceptance or transfers to the owner's operational property program. Water is a particular concern in halls with chilled water or liquid cooling loops, and fire protection impairments during tie-ins need a written procedure. Electronic data and tenant-owned servers are typically outside builders risk entirely and belong in the tenant's own program.
