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.

Steel Cooling: Steel Costs Steadily Decline After Pandemic Price Shock

May 12, 2026 — Construction Executive
Steel prices have continued trending downward after several years of volatility, according to Gordian’s latest analysis based on RSMeans Data. After dramatic spikes during the pandemic-era supply disruptions, the market has gradually stabilized as supply chains improve and demand softens in some construction segments. However, selective volatility and tariff uncertainty continue to influence pricing across the sector. Key findings from the report include:

Steel prices declining: The national average price of structural steel fell to about $2,343.93 per ton in January 2026, down 5.38% from the previous quarter and 7.18% year over year.
Longer-term price correction: Steel costs have been trending downward since 2024 after earlier volatility driven by inflation, supply shortages and global demand swings.

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...

Mandatory Arbitration Isn’t All Bad, if. . .

July 13, 2026 — Christopher G. Hill - Construction Law Musings
In the past week or so mandatory arbitration has been all the rage. From those that argue that arbitration is becoming more burdensome than litigation, to my friend and fellow construction attorney Scott Wolfe who gives great advice on how to make arbitration worth it again. You can place me in the camp of those that think that mandatory arbitration clauses of the type typically found in contracts can add a layer of expense that can be unnecessary. However, if an arbitration clause is carefully drafted, and properly used, these clauses an be helpful in assuring that the streamlining effect for which arbitration was created actually occurs. Because the contract is king in Virginia, these provisions can essentially create the rule of civil procedure used to resolve any dispute relating to the project. Read the full story...

Supreme Court Rules Tariffs Unconstitutional: Why the Construction Industry Shouldn’t Expect Calm Just Yet

March 31, 2026 — Christopher Barnett - Construction Executive
The U.S. Supreme Court’s 6–3 decision in Learning Resources, Inc. v. Trump did what many expected: It held that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. What few anticipated was the speed of what followed: Within hours of the ruling, the administration announced replacement tariffs under Section 122 of the Trade Act of 1974, imposed a 10% global surcharge effective February 24, and signaled forthcoming Section 301 investigations against most major trading partners. For those in the construction industry hoping the Learning Resources ruling would restore market stability, the message was unambiguous. The constitutional question may be settled, but the market disruption is not. Reprinted courtesy of Christopher Barnett, Construction Executive, a publication of Associated Builders and Contractors.

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.

Substantial Evidence of Flood Loss is Not a Substitute for Required Proof of Loss

April 20, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The court found that the insurer properly denied the insured’s claim for loss due to flood because a proof of loss was never submitted. Bay Haven at Coco Bay Condominium Association, Inc. v. Hartford Ins. Co. of the Midwest, 2026 U.S. Dist. LEXIS 6847 (M.D. Fla. Jan. 14, 2026). Bay Haven managed several condo buildings. When Hurricane Ian hit, it caused significant flood damage to these properties. Bay Haven held federal flood insurance policies through Hartford under “Write-Your-Own” policies. This meant Hartford was essentially a fiscal agent that managed policies and handled claims but paid them using federal funds. Following the storm, FEMA extended the usual 60-day deadline for filing a proof of loss to one year, or until September 28, 2023. Bay Haven did not submit its proofs of loss until November 2023. FEMA granted an extension but only for the specific amounts in the November requests. Hartford did not waive the 60-day proof of loss requirement for any other proof of loss. Hartford paid the amounts reflected in the November submissions. Read the full story...

Course of Construction Exclusions and the CGL Policy

July 20, 2026 — Anna M. Perry, Rachel S. Kindseth & Nina Catanzaro - Saxe Doernberger & Vita, P.C.
I. Course of Construction Exclusions Course of Construction (“COC”) exclusions are found on General Liability and excess liability policies, typically a wrap-up or project specific policy, and generally exclude “all property damage occurring during the course of construction.” Insurers claim COC exclusions are not problematic because they are intended to prevent an overlap in coverage between the general liability policy and first-party property Builder’s Risk policy. However, because General Liability policies and Builder’s Risk policies provide coverage for different risks, COC exclusions can create a gap in coverage for owners and contractors. Therefore, any exclusion on a wrap-up or project specific policy that limits coverage for property damage liability should be scrutinized, and amendments sought when warranted and commercially achievable, for owners, developers and contractors because General Liability policies do not cover the same risk as that of a Builder’s Risk policy. General liability policies provide defense and indemnity to the insured(s) for claims made by a third-party against the insured. Broad COC exclusions serve to preclude coverage for all property damage, not just property damage to the insured project. This includes property damage to property other than the insured project, e.g. an adjacent property. On the other hand, Builder’s Risk policies provide first-party property coverage for direct physical loss to the project during the course of construction. The Builder’s Risk policy will not provide coverage for property other than the project itself (e.g., adjacent property) and it will not provide a defense or indemnity in the event the owner of the damaged property brings a claim against a potentially at-fault party.
