Emerging Issues in Construction CGL Insurance Part 2: The Separation of Insureds and Additional Insured Interests

September 29, 2026 — Eric M. Clarkson - SDV Fenchurch
Many coverage disputes hinge on first principles—the fundamentals of insurance —rather than the minutiae. Unfortunately, the basic anatomy of insurance policies can get lost sometimes when parties are laser-focused on a particular term or set of circumstances. This is true not just in disputes, but also when writing coverage. One of the fundamentals that is commonly misunderstood and overlooked—but which is absolutely critical to the intended operation of insurance coverage—is what is commonly known as the “separation of insureds.” The “separation of insureds” is the concept that each “insured” under a policy are referred to and treated differently, and most of all that the distinctions matter. The concept is usually included as a condition in the policy. It embodies the requirement that the policy applies to each insured distinctly from how it applies to other insureds. The ISO Form CGL policies specifically state that they apply “[s]eparately to each insured against whom a claim is made or ‘suit’ is brought.” The separate and distinct treatment of insureds is more critical in construction operations than anywhere else. This distinction is essential to ensure coverage works as intended, especially when contracted operations are involved, because the policy must insure the subcontractor that purchased the policy, the general contractor who hired the subcontractor, and the owner that hired the general contractor. Even small modifications can easily frustrate the intent of the parties. Read the full story...

The GKN Aerospace Chemical Release and the Laws Designed to Address It

July 06, 2026 — Sean M. Sherlock - Snell & Wilmer
On May 21, 2026, a 34,000-gallon storage tank at the GKN Aerospace facility in Garden Grove, California began leaking methyl methacrylate (MMA), a volatile and highly flammable industrial chemical used to manufacture high-strength acrylic plastics. GKN Aerospace makes advanced military and commercial transparencies, such as aircraft canopies, windshields, cabin windows, bullet-resistant glass, and spacecraft windows. In polymer chemistry lingo, MMA is known as a monomer. Monomers are like individual links to a chain. Under the right conditions they link up (react) with each other to form long-chained polymers, or plastics. MMA is an unstable monomer that requires controlled storage conditions to avoid setting off a polymerization (chain) reaction. According to early reports, the MMA tank at GKN Aerospace overheated. The cause of the overheating is not yet clear, but the overheating may have created conditions enabling the MMA to initiate polymerization, which in turn generated heat, which in turn generated pressure, activating the tank’s pressure-relief system and releasing MMA vapor into the atmosphere. Concerns about a runaway reaction, massive release, and explosion led the Orange County Fire Authority to order evacuation of approximately 40,000 residents and closure of thirteen schools.

Insured General Contractor Prevails on Motion for Summary Judgment to Establish Builder’s Risk Coverage

July 06, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The general contractor’s motion for partial summary judgment successfully established that damage to footings in place before the policy period was covered after the collapse of a building. Big D Builders, Inc. v. Am Zurich Ins. Co., 2026 U.S. Dist. LEXIS 72012 (D. Idaho March 31, 2026). Big D was the general contractor for building a new airplane hangar by erecting a 38,000 square foot structure. Before Big D began construction, the site of the hangar did not contain any pre-existing structures or buildings. Before completion of the hangar, it collapsed and caused extensive property damage. The builder’s risk policy issued by Zurich covered certain aspects of the construction project for the policy period December 28, 2023, to December 28, 2024. Zurich accepted coverage for most of the damage but not for damage to footings and columns installed prior to the start date of the policy. Read the full story...

Jurisdiction Over Foreign Manufacturers in Construction Litigation

May 14, 2026 — Timothy J. Repass & Miki J. Saito - Wood Smith Henning Berman
A recent decision from the Washington Court of Appeals provides important guidance on personal jurisdiction over foreign product manufacturers in construction and infrastructure litigation. In King County v. Aquatherm GmbH, No. 85572-7-I (Wash.Ct. App.Div.I)(unpublished), the court addressed whether a German manufacturer could be sued in Washington for alleged defects in piping used in major public infrastructure projects. The ruling offers a detailed, fact-driven roadmap for how Washington courts evaluate jurisdiction over foreign manufacturers operating through layered distribution networks. It also reflects a broader trend toward focusing on real-world commercial conduct rather than formal corporate structure. Background of the Case King County sued after widespread failures in polypropylene piping installed at the King County Correctional Facility. The pipe, manufactured by Aquatherm GmbH in Germany, was marketed, distributed, and installed through a network of U.S.-based entities. Following a six-week trial, the jury returned a verdict exceeding $18 million on claims under the Washington Product Liability Act and Consumer Protection Act. Aquatherm challenged, among other things, the trial court's exercise of personal jurisdiction. Reprinted courtesy of Timothy J. Repass, Wood Smith Henning Berman and Miki J.
