The Who/What/How of Sealing Plans for Architects and Engineers (Law Note)

March 03, 2026 — Melissa Dewey Brumback - Construction Law in North Carolina
The proper use of professional seals in North Carolina is critical. Failure to follow the prescribed requirements can subject you or your Firm to a Board sanction. Did you know that the NC Board of Architecture and the NC Engineering Board have jointly prepared a fairly straightforward document that can tell you exactly what you need to know about sealing of plans? That document, the “Seal Brochure” (pdf) is available for download. Every state’s regulations are a little different (thank you Federalism!) so it is worth reviewing with your staff at regular intervals, especially if you do work across state lines.

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.

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...

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...

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.

Motion for Summary Judgment Granted in Significant California Public Utilities Suit

May 12, 2026 — Dolores Montoya - Bremer Whyte Brown & O'Meara LLP
Congratulations to Partner Mike D’Andrea and Associates Ruth Rasiah and Kaylah Abdullah in the Los Angeles office for obtaining a complete dismissal of their clients in a significant claim involving California’s Public Utilities regulations. After lengthy litigation, BWB&O’s Motion for Summary Judgment was granted against Claimant, Spectrum (Charter Communications), which resulted in a complete dismissal of the action against BWB&O’s clients. At issue was whether California’s Public Utilities Code shifted the common law duty to maintain certain utility equipment in residential areas within Southern California. After significant briefing, the Superior Court found that BWB&O correctly argued that the Public Utilities Code required utility companies, like Spectrum, to fully maintain utility equipment, and that private residents are not responsible for utility maintenance (even if the physical equipment is located on private property).

Las Vegas Partner Jeffrey Saab and Team Leader D. Ryan Efros Secure a $0.00 Settlement on a Multimillion-Dollar Construction Defect Case!

April 14, 2026 — Dolores Montoya - Bremer Whyte Brown & O'Meara LLP
Partner Jeffrey Saab and Team Leader D. Ryan Efros’ client was a construction supervisor on a palatial mansion. The homeowners claimed millions of dollars in damages and asserted the client was a general contractor (GC) and so responsible for the alleged defects. Jeff and Ryan took more than 15 depositions, reinforcing their trial strategy theme: that the client was not a GC, but Plaintiffs were. They secured significant concessions from Plaintiffs, pressed Plaintiffs’ own negligent construction choices, and made the risk of trying the case intolerable. On the eve of trial, Plaintiffs backed down, settling out Jeff and Ryan’s client for $0.00. Read the full story...
