PSA: Be Sure to Document (Even When Time is Short)

April 14, 2026 — Christopher G. Hill - Construction Law Musings
Written change orders are a big deal. Almost all construction contracts (at least the well drafted ones) require written contracts. Written change orders are even important enough that Virginia law requires these provisions in residential construction contracts. Why are they so important? Because they are a “mini-contract” of sorts. They set the expectations, price, time, and work to be performed; work that was not included in the original price or scope for the project. Without this in writing, there will be no record of what the parties agreed to do. Does this sound familiar? Sound like its own contract? It should. Read the full story...

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.

Executive Insights 2026: Leaders in Construction Law

October 06, 2026 — Construction Executive
What advice would you give contractors regarding documentation and recordkeeping to better protect themselves during disputes? Jim Archibald Partner Bradley Arant Boult Cummings LLP Disputes over payment, scope and delays are among the biggest risks contractors face. Thorough documentation doesn’t just help win these disputes; it may prevent them from happening at all. Start with the contract: Every project should begin with a written agreement that clearly defines scope, schedule, payment terms and change-order procedures. Verbal understandings are difficult to enforce. Track changes in real time: Change orders, change directives, RFIs and scope clarifications should always be documented in writing.

D.C. Circuit Upholds EPA’s CERCLA Hazardous-Substance Designations for PFAS as State-Law Settlements Highlight Expanding Liability Landscape

September 15, 2026 — Ashleigh K. Myers, Amanda G. Halter, Jillian Marullo & Anthony B. Cavender - Gravel2Gavel Construction & Real Estate Law Blog
On August 18, 2026, a unanimous panel of the U.S. Court of Appeals for the D.C. Circuit upheld the 2024 designation by the U.S. Environmental Protection Agency (EPA) of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). (See Chamber of Commerce of the United States of America, et al. v. EPA, No. 24-1193 (D.C. Cir. Aug. 18, 2026).) The decision leaves EPA’s PFOA and PFOS hazardous substance designations in place and provides guidance on the scope of EPA’s authority to make future hazardous substances designations under CERCLA Section 102(a). The decision also likely resolves a challenge to the rule that has spanned two presidential administrations. After taking office, the Trump administration had obtained an abeyance of the litigation challenging the Biden-era rule while EPA reconsidered its position. In September 2025, EPA informed the court that it had decided to retain the designations, while signaling that it would work with Congress and industry to address CERCLA liability concerns for “passive receivers.” The litigation then resumed, with the current Administration defending the rule.

New Survey Reveals Overwhelmingly Optimistic Results on the Use of AI in Construction

May 14, 2026 — Construction Executive
On December 5, 2025, CMiC and Dodge released a survey asking over 6,000 companies across various sectors of the construction industry their stance on artificial intelligence—whether they use it or not; whether they like it or not; whether they have or are planning to implement it or not; and so on. Considering its reputation for skepticism and reluctance when it comes to adopting new forms of technology, the construction industry pleasantly surprised CMiC and Dodge with its answers to these questions, with 87% of contractors believing AI will have a meaningful impact on construction. “The research indicates the construction industry is nearing a tipping point for AI adoption,” says Steve Jones, senior director of industry insights at Dodge Construction Network, who sat down with Construction Executive to delve further into the survey questions and answers and what the industry’s current position on them means for AI’s future role in construction.

AI & Digital Tools on Construction Projects: Contract Risks to Address Before Peak Season

April 08, 2026 — Meghan Douris - The Construction Seyt
Artificial intelligence and advanced digital tools are no longer experimental on construction projects. In Q1 of 2026, we can already see how they are already influencing schedules, estimates, submittals, safety reporting, and day‑to‑day project documentation. As peak construction season approaches, many teams are accelerating adoption of AI to gain efficiency. What often lags behind, however, is the contract framework governing how those tools are used—and how their outputs are treated when something goes wrong. On sophisticated construction projects, that gap can quickly become a dispute driver. Read the full story...
