Insufficient Notice of Commencement and Construction Lien Rights

August 03, 2026 — David Adelstein - Florida Construction Legal Updates
When a party is preserving their construction lien rights, the party will look to the recorded Notice of Commencement. This is the recorded document that provides the lienor with the information for purposes of preserving construction lien rights. A Notice to Owner company will typically rely on the Notice of Commencement to serve Notices to Owners from lower tiers not in contract with the owner. However, when it comes to preparing the lien, a lienor should look beyond just the Notice of Commencement and also look to the property appraiser’s website as a backstop. In a recent case, a window company had the homeowner sign the Notice of Commencement and then filled in the information. The company naturally did this for the convenience of the homeowner that probably was unfamiliar with the Notice of Commencement process. Regardless, information in the Notice of Commencement was inaccurate. It failed to include all the real property owners. Thus, when a payment dispute arose and a construction lien was prepared, it did not identify all of the real property owners. All of the real property owners were added later during the pendency of a lien foreclosure lawsuit. The trial court denied the lien because of the defective / insufficient Notice of Commencement — the lienor assumed the risk of error by filling out the information in the Notice of Commencement. The trial court further denied the lien holding that because the work did not commence within 90 days of the Notice of Commencement, the Notice of Commencement is void. 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.

Micromobility in Smart Cities: Keeping the Wheels in Motion

May 26, 2026 — James P. Bobotek - Gravel2Gavel Construction & Real Estate Law Blog
Mobility is the lifeblood of any city. How people are able to travel in, out and within a metropolitan area is vital to its citizens, businesses, supply chains and social services. And as U.S. cities have expanded in size and population density, the strategies for addressing mobility have evolved. Many have taken different approaches to public transit, and each city boasts a dense tapestry of roadways, walking paths and various parking options. But as cities continue to reexamine infrastructure strategies through smart city technology, a new field of transportation has emerged—micromobility. Designed for short-distance travel using lightweight vehicles (bikes, e-bikes, e-scooters, etc.), the industry’s global net worth has grown exponentially in recent years to the tune of hundreds of billions, with one forecast predicting it could reach $340 billion by 2030. Micromobility also finds itself at the forefront of various smart city technological improvements. Geofencing has been implemented in U.S. cities to determine where micromobility vehicles can operate, control speed limits, and park utilizing the vehicles’ GPS location. Internet of Things (IoT) technologies (satellite-based location receivers, cloud communication, internet links, etc.) have improved vehicle lifespans by keeping track of when vehicles require service and prevent vandalism and theft. Data collected from vehicles’ location tracking is routinely used for urban planning and smart city development. Read the full story...

Seattle Team Obtains Summary Judgment in Real Estate Broker Professional Liability Action

July 20, 2026 — Lewis Brisbois
Seattle Partner Kathleen A. Nelson and Associate Synova M. L. Edwards prevailed on a hotly contested motion for summary judgment in Whatcom County, Washington court in a real estate broker professional liability action. The plaintiff filed an action against Lewis Brisbois' clients, a real estate agent and brokerage firm, among several others, including the title company, purchasers and others related to the sale of real property following his complicated and long running divorce action. These claims primarily arose out of the clients’ reliance on an order signed by the court in the underlying divorce action. The order allowed the clients to execute the purchase and sale agreement, as the plaintiff was non-cooperative. Read the full story...

What Massachusetts Contractors and Developers Can Learn from Cannistraro v. Columbia Construction

July 13, 2026 — Anthony LaPlaca & Luke Marston - The Construction Seyt
Introduction On June 26, 2026 the Massachusetts Supreme Judicial Court issued its decision in J.C. Cannistraro, LLC v. Columbia Construction Co.—a holding that sits at the intersection of Prompt Pay Act compliance and the Massachusetts Arbitration Act.[1] Most already know that the Massachusetts Prompt Pay Act (PPA) imposes strict timing and certification requirements for rejecting payment applications and proposed change orders on projects valued at $3 million or more. Most notably, the PPA requires the paying party to give the payee written notice of its approval or rejection of progress applications and proposed changes within 15 days of receipt, which notice must include a “factual and contractual basis for the rejection” and must be “certified as made in good faith.”[2] In the absence of a timely certified notice, payment is “deemed to be approved” unless the payor properly rejects payment before it comes due.[3] Reprinted courtesy of Anthony LaPlaca, Seyfarth Shaw LLP and Luke Marston, Seyfarth Shaw LLP Mr. LaPlaca may be contacted at alaplaca@seyfarth.com Mr. Marston may be contacted at lmarston@seyfarth.com Read the full story...
