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.

IEEPA Tariff Refunds: CBP Launches CAPE Process

April 27, 2026 — David J. Creagan, Guido Antolini, Bruce W. MacLennan & Gary P. Biehn - White and Williams LLP
On April 20, 2026, U.S. Customs and Border Protection (CBP) launched the first phase of the Consolidated Administration and Processing of Entries (CAPE) tool in the Automated Commercial Environment (ACE) portal to administer refunds of duties imposed under the International Emergency Economic Powers Act (IEEPA) through a streamlined electronic filing process. Background In February 2026, the U.S. Supreme Court held that certain tariffs imposed under IEEPA were unlawful. Subsequent proceedings before the U.S. Court of International Trade required CBP to develop a scalable refund process applicable not only to litigants but also to non-plaintiffs. According to CBP and court filings, approximately 330,000 importers paid or deposited an estimated $166 billion in IEEPA duties across more than 53 million entries. In response, CBP developed CAPE as an electronic, consolidated refund mechanism within ACE. Reprinted courtesy of David J.

Texas Prepares to Restart Data Center Construction, with Around 300 Projects Under Review And 6,608 MW Awaiting Energization Approval, Driving Demand for Rapid-Response Lifting Operations

October 20, 2026 — Sarens
Texas is experiencing an unprecedented increase in power demand. The ERCOT (Electric Reliability Council of Texas) power grid reached a record peak demand of 91.1 GW in summer 2026, 6% above the previous record, according to the U.S. Energy Information Administration (EIA). This is compounded by interconnection requests totaling around 474 GW, more than five times the record peak, with approximately 90% of these requests related to data centers, according to the Office of the Governor of Texas. Within this context, authorities have launched a comprehensive review process. In August , the Governor directed the Public Utility Commission of Texas (PUCT) and ERCOT to audit all data centers progressing toward grid connection, covering around 300 projects. ERCOT has also suspended approvals to energize data centers of 75 MW or more and has set December 10 as the date for the publication of its reports. For the industry, this pause creates a valuable planning window. Goldman Sachs notes that it takes 18 to 24 months to build a data center once permits have been secured, while only 50% to 60% of planned capacity is delivered on schedule. Supply chain constraints and labor shortages are among the most common causes of delays. In this context, construction agility is becoming increasingly critical. A one-month delay at a typical 60 MW U.S. data center is estimated to cost up to $14.2 million in lost revenue, additional costs and penalties, according to STL Partners data. Against this backdrop, Sarens, which has operated in the U.S. since 2009 and is headquartered in Houston, with offices also in Odessa and Beaumont, positions as a logistics partner for developers and contractors preparing for the execution phase.

Late Notice Bars Insured’s Claim for Wind Damage

June 29, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The court found that a six-month delay in reporting damage from wind did not comply with the policy’s notice requirements. Touchmark Hotel Group, LLC v. Mt. Hawley Ins. Co., 2026 U.S. Dist. LEXIS 61910 (S.D. N. Y. March 24, 2026). A storm caused damage to Touchstone’s hotel on January 4, 2023. Touchstone’s corporate representative, Rohit Patel, testified that he was not at the property on the day of the storm. In a telephone call the next day, the manager of the property reported to Patel that he observed detached shingles from the roof the hotel in the parking lot. Patel testified that he did not file a claim at that time because Touchmark’s employees did not detect any water leakage in the building and because he did not believe that the cost of the damage from the storm would exceed the policy’s deductible.

Could Your Project-Level AI Prompt Become the Other Side’s Smoking Gun?

October 20, 2026 — Ryan Glass - ConsensusDocs
A dispute is brewing on the project. Wanting a quick assessment, the project manager opens ChatGPT, Claude, or another generative artificial intelligence (“AI”) platform. The project manager types the dispute background into the prompt, including concerns, explanations, and a frank discussion of what may have gone wrong on the contractor-side. The AI response identifies potential weaknesses in the contractor’s position, including possible failures to meet contractual obligations. Unhappy with the answer, the project manager starts a new chat, revises the prompt, and tries again. If the dispute escalates to arbitration or litigation, can the owner force the contractor to provide these prompts and the resulting responses? Frustratingly, the answer is: it depends. Courts have reached different conclusions. For now, the safest course is to involve your counsel before using AI to evaluate a demand letter, default notice, or threatened lawsuit, or before using AI to draft dispute-related emails, claim letters, or other communications that contain project-specific facts. Otherwise, what feels like a private conversation may later become key evidence for the opposing party. Read the full story...

New Law Prompts ABC Minnesota/North Dakota to Design New Telecommunications Safety Training Program

June 29, 2026 — Grace Calengor - Construction Executive
On the first day of the year, a Minnesota law requiring installers of underground telecommunication infrastructure broadband, fiber or phone lines (when projects utilize directional drilling, and/or work is being conducted within 10 feet of existing utilities) to undergo a 40-hour certification went into effect. Originally passed in mid-2024 and proposed to go into effect in July 2025, the law’s requirements were postponed until January 2026, giving ABC Minnesota/North Dakota—in partnership with NCCER and the Minnesota Cable Communications Association—time to roll out their Safety Qualified Underground Telecommunications Installer training program, which would ensure the workforce of their contractor members were certified.
