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.

Daily Journal Publishes Article by Brenda Radmacher on Proposed Overhaul of California Construction Defect Law

June 29, 2026 — Brenda Radmacher - The Construction Seyt
Daily Journal (California) featured an article by Construction Law partner Brenda Radmacher, “A new path for construction defects in California.” The piece, published on June 15, 2026, examines Assembly Bill 1903 and its potential to significantly reshape California’s construction defect framework, particularly for common interest properties. The article highlights how AB 1903 would overhaul the state’s current right-to-repair system by mandating completion of prelitigation procedures, raising requirements for defect claims, strengthening developers’/builders’ rights to repair, and introducing a voluntary “certified building” program. The legislation aims to rebalance competing interests by reducing litigation-driven costs while preserving protections for homeowners. Read the full story...

The Most Expensive Signature to Not Get: Why Change Orders Matter

August 16, 2026 — Kathryne E. Baldwin - Wilke Fleury
George Bernard Shaw has a quote we use a lot in my family: “The single biggest problem in communication is the illusion that it has taken place.” This is pertinent to contractors and homeowners alike because the cost of failing to get proper signatures on documents like construction contracts, and particularly, change orders, is heavy. Both contractors and homeowners are in the same boat as far as wanting to complete a job as swiftly as possible: contractors go on to their next job and homeowners can return to peace in their home. This is prime territory for either party to suggest the work be completed today and the contract or change order executed tomorrow, or even later. However, without a contract, there is no memorialization of the communication between the parties, which can lead to confusion and missed expectations on both sides. Construction plans are rarely as neat and tidy as they originally seem to be. A contractor may uncover unforeseen conditions, an owner may request additional work or changes that require additional work, or weather interferes with project schedules or the work itself. Unfortunately, the signature that never gets collected can become one of the most expensive omissions on a project – for both sides. Read the full story...

Arizona Court of Appeals Clarifies Homeowners Association Open Meeting Requirements

June 29, 2026 — Jill Casson Owen, Benjamin J. Hawkins & Stephen Wright - Snell & Wilmer
A Z N H Revocable Trust v. Sunland Springs Village Homeowners Association, No. 1 CA-CV 25-0424 (Ariz. Ct. App. Apr. 28, 2026) OVERVIEW The Arizona Court of Appeals issued an opinion clarifying how homeowners associations must conduct meetings under A.R.S. § 33-1804. The decision reinforces the legislative policy favoring transparency in association governance, bringing association meeting requirements more in line with the open meeting standards applicable to public bodies under A.R.S. § 38-431 et seq. (Arizona’s Open Meeting Law). KEY HOLDINGS 1. All Voting and Formal Actions Must Occur in Open Meetings The Court affirmed that association boards cannot vote or take formal action during closed (executive) sessions. Under A.R.S. § 33-1804(A), associations may close portions of meetings only for “consideration” of certain enumerated topics, such as legal advice, pending litigation, or personal/financial information about individual members. The Court interpreted “consideration” to mean discussion and deliberation, not voting. The Court noted that dictionaries define “consider” as “spending time thinking about a possibility” and “formulating an opinion,” which are processes that precede formal action. This interpretation mirrors how Arizona’s Open Meeting Law (A.R.S. § 38-431.03(D)) prohibits public bodies from voting in executive session.

Beyond the Forecast: Managing Extreme Weather Risks on Construction Sites

November 02, 2026 — Jordan Graustark - Construction Executive
Construction leaders would never downplay or dismiss a fall, struck-by incident or equipment failure as “just part of the job.” Yet, some temperature-related conditions, such as heat exhaustion, frostbite and hypothermia, are often accepted as unavoidable consequences of working conditions. Temperature-related incidents likely won’t command the same attention as a crane collapse, but understating their seriousness can be a costly mistake. As extreme weather becomes more frequent and unpredictable, that mindset is becoming increasingly difficult to defend. Extreme weather is not simply a seasonal inconvenience; it’s a serious occupational hazard. Heat waves, cold snaps and rapid temperature swings can contribute to serious injuries and fatalities—or SIFs—productivity losses and costly project disruptions. A single temperature-related incident can quickly become an OSHA recordable and project management challenge. Reduced physical and impaired cognitive performance from heat or cold stress can increase the risk of workplace incidents long before a medical emergency occurs.
