Science-Based Standards for Wildfire Recovery: What California Policyholders Need to Know About A.B. 1642

March 03, 2026 — Geoffrey B. Fehling & Yosef Itkin - Hunton Insurance Recovery Blog
Wildfires continue to present serious risks for California property owners. Unfortunately, commercial property owners, corporate facilities, landlords, and homeowners need to overcome not only the flames themselves, but also remediating hazardous contamination against a backdrop of unpredictable and ambiguous environmental safety standards. In response to the destructive Los Angeles area fires in 2025, the California Legislature recently introduced Assembly Bill 1642 aimed at creating uniform science-based standards for evaluating, testing, and clearing wildfire-impacted properties. While A.B. 1642 is in its early stages of consideration, it could materially influence claims handling, remediation costs, risk management practices, and broader liability exposures for California policyholders.

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.

WASHINGTON -- The American Council of Engineering Companies (ACEC), the business voice of America’s engineering and design services industry released the following statement on the BUILD America 250 Act: "Chairman Graves and Ranking Member Larsen have taken an important bipartisan step toward reauthorizing the federal surface transportation programs that are critical to economic growth in every state. The BUILD America 250 Act provides five years of stability in funding road and transit projects, raises new revenues to address the solvency of the Highway Trust Fund, and includes meaningful provisions to strengthen project delivery, advance digital infrastructure, and improve the contracting framework that engineering firms rely on every day. ACEC will continue to advocate for investment levels that keep pace with the country's growing infrastructure needs, and we urge the Committee to keep this process moving forward." The American Council of Engineering Companies (ACEC) is the business association of America’s engineering industry, representing more than 5,500 independent engineering firms and more than 650,000 professionals throughout the United States engaged in the development of America’s transportation, water, and energy infrastructure, along with environmental, industrial, and other public and private facilities.

Ownership and Licensing in Design Agreements

April 14, 2026 — Abby Dvorkin - Snell & Wilmer
The ownership and licensing of design documents in professional services agreements play a significant role in protecting the interests of the design professional and the project owner during and after project completion. The ownership or licensing of the drawings provision typically outlines who owns the drawings and specifications, who can use the documents, and how the documents can be used during and after the project. Project owners and developers should understand that payment for design services does not automatically transfer ownership or an exclusive right to use the professional design. Under U.S. copyright law, the default rule is that the design professional retains ownership of the instruments of service absent a contractual provision transferring ownership or a license. See 17 U.S.C. § 101, et seq. The Architectural Works Copyright Protection Act provides that copyright protection applies to “pictorial, graphic and sculptural works” and includes “architectural works.” 17 U.S.C. § 102. A design professional may only transfer copyright ownership in writing. 17 U.S.C. § 204(a). Read the full story...

Endra Rethinks MEP Design with AI

July 06, 2026 — Aarni Heiskanen - AEC Business
Niklas Lindgren, co-founder and CEO of Endra, joins the AEC Business Podcast to discuss why his Stockholm-based startup is rebuilding MEP design from the ground up with AI. Endra recently raised $50 million in Series A funding and counts some of the world’s largest engineering consultancies as customers. Niklas explains why Revit’s underlying data model is too coarse to support deep automation, and why Endra built its own granular 3D data model instead of working as a plugin. He describes Endra’s “spatial AI” approach to routing conduit and ductwork without clashes, and how the platform models entire electrical systems, from receptacle to transformer, inside a single source of truth.
