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.

Hidden Risks Behind Today’s Stadium Construction Boom

July 20, 2026 — Thomas Strong, Andrew Canning & Marc Gnesin - Construction Executive
After a decade-plus lull, professional sports leagues, universities and municipalities are once again spending heavily on new stadiums and major renovations. In the NFL alone, multiple marquee projects are underway or planned, representing more than $10 billion in facilities and mixed-use entertainment districts, rivaling or exceeding the scale of development during the last stadium-build cycle of the early 2000s. Beneath the excitement of architectural ambition and civic pride lies a risk landscape that has fundamentally changed since the last wave of stadium construction. Teams, cities and contractors that rely on outdated assumptions may find themselves exposed to cost overruns, schedule delays and liabilities that are far more difficult to unwind once construction is underway.

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...

Potential Gap in Workers Compensation Immunity Statutory Framework

June 02, 2026 — David Adelstein - Florida Construction Legal Updates
Workers compensation insurance is important. As an owner, you want to ensure the contractors you hire have workers compensation insurance. Assuming you hire a contractor that is statutorily exempt from workers compensation, you want to make sure, no exception, that any subcontractor that is hired has workers compensation insurance. (Regardless, you always want subcontractors to have workers compensation insurance.). In construction, the prime contractor serves as the “statutory employer” for purposes of workers compensation insurance. With workers compensation comes workers compensation immunity.

$10.5M Settlement Ends George Washington Bridge Debris Liability Fight

September 15, 2026 — Bryan Gottlieb - Engineering News-Record
A $10.5-million settlement that recently came to light has ended a six-year legal fight over whether a truck part that may have been lying on the George Washington Bridge roadway for more than 10 minutes was there long enough for the Port Authority of New York and New Jersey to have found and removed it before it caused a catastrophic accident.

Wadsworth v. Regional Rail Partners — Verified Statements of Claim Under the Colorado Public Works Act

August 25, 2026 — Olivia Barden - Colorado Construction Litigation Blog
Editor’s Note: Wadsworth Revisited In August 2024, following the Colorado Court of Appeals’ decision in Ralph L. Wadsworth Construction Company, LLC v. Regional Rail Partners, we published Colorado Court of Appeals’ Ruling Highlights Dangers of Excessive Public Works Claims. At the time, the decision warranted a significant warning to contractors and subcontractors performing public work in Colorado. The Court of Appeals concluded that Wadsworth’s verified statement of claim improperly included unliquidated delay damages and that, because the claim was excessive, Wadsworth forfeited its right to recover the amounts included in the claim. We cautioned contractors to carefully scrutinize verified statements of claim and to avoid including unliquidated damages or amounts that were not yet due and payable. The Colorado Supreme Court has now reversed that decision. Read the full story...

Consider The Limited Warranty from Your Homebuilder

July 06, 2026 — David Adelstein - Florida Construction Legal Updates
When purchasing a home from a homebuilder, there is an important consideration when it comes to the limited warranty you receive around the time you close on the home. That limited warranty likely includes an arbitration provision requiring you to arbitrate your disputes, such as construction defect claims, against the homebuilder. That arbitration provision will most likely include all claims, including statutory claims (such as a statutory violation of a building code claim), requiring you to arbitrate, as opposed to litigate, your disputes against the homebuilder. This is an important consideration. If the arbitration provision does not allow you to arbitrate all of your claims, and eliminates your rights to legitimate statutory claims, the arbitration provision could be unenforceable. By way of example, in a residential construction defect dispute, Anderson v. Taylor Morrison of Florida, Inc., 223 So.3d 1088 (Fla. 2d DCA 2017), the appeal turned on whether the arbitration provision in the homebuilder’s limited warranty was valid. The homeowners took possession of their home in 2009. In 2015, the homeowners served a Florida Statutes Chapter 558 notice of construction defects that included a statutory violation of a building code claim under Florida Statute §553.84. The limited warranty included an arbitration provision that specified it was the “exclusive remedy” for all disputes arising out of or related to the warranty or issues with the home and property. When read together with the warranty’s disclaimer that precluded claims not covered by the warranty “whether in contract, tort, or otherwise,” the statutory building code violation claim could not be remedied through arbitration because it fell outside the warranty’s coverage.
