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.

New York Orders Moratorium on Large Data Center Permits

July 27, 2026 — Levi W. Barrett - Peckar & Abramson, P.C.
Levi W. Barrett, Co-Managing Partner of Peckar & Abramson’s New Jersey office, Co-Chair of the firm’s Construction Contracts & Risk Management team, and Executive Committee Member, was recently quoted in “New York Orders Moratorium on Large Data Center Permits,” an article written by Engineering News-Record (ENR). The article examines New York Governor Kathy Hochul’s executive order temporarily halting state environmental permit reviews for certain large-scale data center projects while regulators develop a comprehensive framework to address the sector’s energy demands, water consumption, environmental impacts, and effects on local communities. It also explores the broader implications of the moratorium for developers, contractors, investors, and other stakeholders, as well as the ongoing debate between economic development, AI-driven infrastructure growth, and environmental and utility ratepayer concerns.

The Single Source of Truth in Construction Projects: Reality or Myth?

March 24, 2026 — Aarni Heiskanen - AEC Business
The idea of a single source of truth has been a fundamental part of the digital vision in the AEC industry for many years. From centralized CAD storage to BIM collaboration platforms and, more recently, Common Data Environments, the goal stays the same. Project teams want a reliable place where everyone can access the latest information. The phrase “single source of truth” comes from database and information management practices in the IT world, where the goal was to maintain one authoritative record of data and eliminate data redundancy. As the AEC industry began adopting digital tools, the same idea was applied to project information and workflows. Despite decades of technological progress, the question remains whether “one ring that rules them all” can actually be implemented in real construction projects. Read the full story...

Defend Now, Allocate Later? An Unresolved Tension in Colorado Construction Law

August 16, 2026 — David McLain - Colorado Construction Litigation Blog
For decades, Colorado law has recognized an important distinction between the duty to defend and the duty to indemnify. The former ordinarily arises at the beginning of litigation; the latter generally cannot be determined until the underlying liability is known. That distinction makes intuitive sense. A defense that becomes due only after litigation concludes is not much of a defense. But Colorado’s construction anti-indemnity statute, C.R.S. § 13-21-111.5(6), raises an interesting question about how that familiar rule operates in construction disputes. The statute expressly regulates contractual obligations not only to indemnify, but also to insure and defend, and it reflects a legislative policy that construction businesses should bear financial responsibility for their own negligence. Those principles have developed along separate tracks. At some point, a Colorado appellate court may have to decide precisely how they fit together. Read the full story...

Lost in Translation: AEC Tech’s Missing Role

May 12, 2026 — Aarni Heiskanen - AEC Business
I once visited a construction site where the contractor’s headquarters had commissioned a tech company to build an on-site quality-inspection application. The developer had admitted to the site engineer that they had never set foot on a construction site before. The engineer showed me what he was actually using: his own phone camera and an Excel sheet. The new app did not map to how work actually happened on site. This is not an isolated story. The vendor builds something technically coherent but operationally disconnected. The client, somewhere up the chain, had fallen in love with the idea of the solution before anyone had built an honest business case for it. The result is a tool that gets demonstrated at a board meeting but isn’t used in the field. 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.

Quick Note: Don’t Spoil Evidence!!!!

March 10, 2026 — David Adelstein - Florida Construction Legal Updates
The phrase “spoliation of evidence” is a phrase that gets used, sometimes properly and sometimes improperly. The reason is that if evidence is legitimately spoiled, the opposing party wants an adverse inference jury instruction. There are two potential adverse inference jury instructions dealing with spoliation of evidence, neither of which are good, and one of which you definitely don’t want. A recent case discusses these jury instructions (check here) in a slip and fall personal injury case. The bottom line is that you need to preserve evidence relevant to a claim. Don’t lose it. Don’t intentionally destroy it. Don’t pretend it does not exist. Don’t do all the things that hinder the preservation and ultimate production of the relevant evidence. An adverse inference jury instruction (or an adverse inference implication in a non-jury trial) could be much, much worse. The facts are what the facts are. The best thing you can do is confront the facts. Confront the bad facts just like the good facts. The nature of any dispute is that there will be both good and bad facts. Bad facts can hopefully be explained recognizing there will be bad facts on the other side too. Sometimes, the bad facts warrant major strategic considerations and shifting the focus of how a dispute will be handled and presented. Whatever you do, don’t put yourself in a position where you are spoiling evidence. Once you get an adverse inference instruction, that’s it, as it’s very tough to overcome. Read the full story...
