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.

Construction Contract Negotiation & Drafting: A Practical Checklist (and Where State-Specific Issues Can Surprise You)

April 20, 2026 — Michelle Cooper - Sheppard Construction and Infrastructure Law Blog
Construction contract negotiation is often treated as a “forms exercise,” especially when the parties start from familiar templates (e.g., AIA forms). In practice, though, the biggest problems tend to arise not from the existence of a form, but from (i) misalignment among the project’s governing documents and participants, (ii) ambiguity in pricing and payment mechanics, and (iii) state-specific statutory requirements that override negotiated terms. This article includes a practical checklist intended to help owners, developers, and contractors streamline contract negotiations, reduce downstream disputes, and avoid unpleasant surprises during payment administration.

Colorado Court Affirms Attorneys’ Fee Award Against Plaintiff’s Counsel for Pursuing Unsupported CCPA Claims

August 03, 2026 — David McLain - Colorado Construction Litigation Blog
The Colorado Court of Appeals recently affirmed a trial court’s award of more than $241,000 in attorney fees against a plaintiffs’ attorney who continued to pursue unsupported claims arising out of a residential construction dispute. Although the opinion was not selected for official publication under C.A.R. 35(e) and therefore has no precedential value, it nevertheless provides an instructive reminder that Colorado courts are willing to impose significant financial consequences when claims lack substantial justification. For builders, developers, contractors, insurers, and defense counsel, the case is worth reading, not because it announces new law, but because it demonstrates that Colorado’s fee-shifting statute remains a meaningful tool when unsupported claims continue long after they should have been abandoned.

Structuring Water Resilience for Data Center Development: Water Rights, Reuse Incentives, and Emerging Disclosure Risk

March 10, 2026 — Ashleigh Myers, Jillian Marullo & Jason Drogin Atwood - Gravel2Gavel Construction & Real Estate Law Blog
As AI-driven data center development accelerates, developers, communities and regulators are increasingly focused on water demand—both the volume required and the sources from which that water will be drawn. While industry attention has largely centered on electricity procurement and grid impacts, the availability and legal entitlement to a firm water supply has become equally material to siting, permitting and community acceptance. Particularly as surface and groundwater supplies become increasingly constrained and new projects are sited in regions experiencing tighter hydrologic conditions or growth-related supply constraints, project teams are increasingly integrating water supply analysis into early-stage development to address issues that can materially affect schedule, financing and long-term operations.

Tariffs As Taxes — What Learning Resources, Inc. v. Trump Means for Contractors and the WSDOT Specifications

March 17, 2026 — Brett M. Hill - Ahlers Cressman & Sleight PLLC
In October 2025, we explored a pressing question for public works contractors: should post-contract award tariffs be reimbursable? The crux of that analysis was whether tariffs imposed after contract award constitute a tax under the Washington State Department of Transportation (WSDOT) Standard Specifications, triggering reimbursement under Section 1-07.1(5)B (“tax changes”). Since then, a landmark Supreme Court ruling in Learning Resources, Inc. v. Trump has clarified the legal nature of tariffs in a way that could significantly affect this debate. In Learning Resources, Inc. v. Trump, 607 U.S. (2026), the U.S. Supreme Court addressed whether the President had the authority under the International Emergency Economic Powers Act (IEEPA) to unilaterally impose broad tariffs on imports.

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...

Why Construction Tendering Needs Specialized Intelligence

March 31, 2026 — Aarni Heiskanen - AEC Business
The construction industry has never lacked data; it lacks usable intelligence at the moments that matter most. In the high-stakes phases of tendering and pre-construction, the industry still relies on manual “Control-F” searches through thousands of pages of unstructured documents. I recently spoke with Herman Smith, a civil engineer and former Chief Digital Officer at Multiconsult, who left the corporate world to solve this specific bottleneck. His startup, Volve, isn’t just another AI wrapper; it is a specialized “drill” designed to penetrate the complexity of construction documentation. The Paradox of Digitalization without a Productivity Boost For years, the AEC industry has faced a frustrating paradox: we have more digital tools than ever, yet productivity has not improved. Herman observed this from the inside, managing hundreds of unique software licenses while seeing companies struggle to adapt to new workflows. Read the full story...
