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.

ACEC Supports BUILD America 250 Act as Important First Step on Surface Reauthorization

May 26, 2026 — The American Council of Engineering Companies
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. Founded in 1906 and headquartered in Washington, D.C., ACEC is a national federation of 51 state and regional organizations.

Inaccurate Representations Can Lead to Differing Site Conditions Claim

May 26, 2026 — David Adelstein - Florida Construction Legal Updates
In the prior posting, I discussed a case dealing with a differing site condition. In that case, the owner did not have an affirmative duty to make a representation and there was no inaccurate representation made by the owner that misled the contractor. Well, what about when there is an inaccurate misrepresentation regarding the site? This was the circumstance in an older Florida case where a dredging contractor had a successful differing site conditions claim. See Jacksonville Port Authority v. Parkhill-Goodloe, Co., Inc., 362 So.2d 1009 (Fla. 1st DCA 1978). The government provided inaccurate information as to the lack of rock that would be encountered during the dredging that was relied on by the dredging contractor. But the government had “superior knowledge” that there was rock in an adjacent location based on a prior claim from a contractor, yet the government did not disclose the possibility that rock could be encountered.

Sausage-Making Often Relies on the Good Sense of the Chef Rather than the Recipe

June 23, 2026 — Garret D. Murai - California Construction Law Blog
Even for lawyers, the rules governing litigation can get complex and convoluted. Does something need to be filed? What needs to be filed? When is the deadline for filing? Simple questions with not always with straightforward answers. This was the case in R & J Sheet Metal, Inc. v. W.E. O’Neil Construction Co. of California, 111 Cal.App.5th 878 (2025), which involved sheet metal panels lost when they fell into the Port of Long Beach harbor. Read the full story...

Construction Companies Are Nearly Seven Times Safer With These Best Practices

June 15, 2026 — ABC - Construction Executive
WASHINGTON, May 4—Associated Builders and Contractors released its 2026 Health and Safety Performance Report, an annual guide to health and safety best practices on construction jobsites. The 2026 report shows the positive effects of participating in ABC’s STEP® Health and Safety Management System, which enables top-performing ABC members to achieve incident rates 686% safer than the U.S. Bureau of Labor Statistics construction industry average, reducing total recordable incident rates by 85%. Established in 1989, STEP is a proven system that provides contractors and suppliers with a robust, no-cost framework for measuring health and safety data and benchmarking with peers in the industry. This self-assessment tool helps participants identify real opportunities for scalable growth in their health and safety programs to lower their total recordable incident rates and become an employer of choice in a competitive labor market.

A Win for Clarity: What a Recent Federal Court Decision Means for Davis-Bacon Compliance

July 13, 2026 — Stephen E. Irving - Peckar & Abramson, P.C.
Following the Department of Labor’s 2023 Davis-Bacon rule changes, federal construction contractors faced a pressing question: not whether paying prevailing wages is required, but how far those obligations could extend. Could they reach off-site material suppliers? Delivery drivers? Contracts that omitted Davis-Bacon clauses entirely? A recent federal court decision in AGC of America v. US Department of Labor answers these questions in important ways, vacating several disputed provisions and giving contractors greater certainty when pricing, bidding, and administering federal construction projects. The ruling addresses three aspects of the 2023 regulations that sought to extend Davis-Bacon obligations beyond their traditional scope. By vacating those provisions, the decision creates a more predictable compliance environment and reinforces an important principle: Davis-Bacon enforcement works best when contractors, workers, and regulators operate under clear, objective rules.

Bridging the Gap at Alaska’s Juneau Creek

September 21, 2026 — Tim Newcomb - Engineering News-Record
The largest single-span steel plate girder bridge launch in the nation wasn’t about setting records. Alaska’s Juneau Creek Bridge design was a matter of necessity. The fully erected steel plate girder bridge, featuring a 440-ft main span hovering 285 ft above the Juneau Creek, was part of the larger Sterling Highway project. It offered a logistical challenge but was chosen among over a dozen bridge types due to the unique constraints brought by the mountainous site. Read the full story...

EPA Steps Back, Arizona Moves Forward

May 12, 2026 — Patrick J. Paul, John Habib & Sukhmani K. Singh - Snell & Wilmer
In a significant development for Arizona’s business community and environmental policymakers, the U.S. Environmental Protection Agency (EPA) has paused its planned reclassification of Maricopa County from “Moderate” to “Serious” ozone nonattainment status pursuant to the Clean Air Act’s National Ambient Air Quality Standards (NAAQS). This decision marks a shift in federal air policy — one that recognizes the unique challenges faced by regions like metro Phoenix, where environmental conditions beyond local control are often key contributors to air quality readings. The EPA’s move follows a series of meetings between EPA Administrator Lee Zeldin, Arizona elected officials, and business and civic leaders, including a recent roundtable in Phoenix convened by U.S. Senator Mark Kelly. In announcing the pause, Zeldin acknowledged the need for flexibility and fairness in the application of Clean Air Act standards, especially when emissions from other states, nations, and natural events significantly influence local air quality.
