Alert: Fraudulent Notice of Nonpayment Defense Applies to Payment Bond Claims

April 27, 2026 — David Adelstein - Florida Construction Legal Updates
Under Florida’s Lien Law, there’s an affirmative defense or affirmative claim known as a “fraudulent lien.” The fraudulent lien defense or claim is set out in Florida Statute s. 713.31. This defense also extends to payment bond claims, whether under a private statutory payment bond (Florida Statute s. 713.23) or a public payment bond (Florida Statute s. 255.05), as it pertains to the notice of nonpayment. A notice of nonpayment needs to be served within 90 days from final furnishing to preserve a claimant’s rights against the bond. However, there really has not been a case, until now, that discusses a “fraudulent notice of nonpayment.” In K&M Electric Supply, Inc. v. Brown Electrical Solutions, LLC, 51 Fla.L.Weekly D672a (Fla. 4th DCA 2026), a prime contractor and surety prevailed at the trial level on their fraudulent notice of nonpayment defense based on a supplier’s notice of nonpayment and action against a public payment bond (under Florida Statute s. 255.05).

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.

Construction Robotics Works Where Variation Ends

August 11, 2026 — Aarni Heiskanen - AEC Business
BuiltWorlds published its 2026 Robotics Top 50 this summer, and the list is genuinely wide. Fifty solutions across nine categories, from 3D printing and prefabricated component manufacturing to earthmoving, demolition, material transport, layout, installation, inspection, and drilling. The honorees come from sixteen countries. It looks like robotics has finally spread across the whole project lifecycle. However, having vendors in nine categories does not mean that contractors are robotizing their work en masse. Zacua Ventures, in its 2026 construction robotics report, estimates that on-site robotics accounted for less than 0.03% of global construction spending in 2025. Zacua says: “That is not a failed market. It is a market at the beginning of an adoption S-curve”, while warning that its estimates rest on private vendor data and may be high if vendors overstate how widely their machines are deployed.

Building the Research and Healthcare Facilities of Tomorrow Without Impacting the Progress of Today

August 16, 2026 — Jason Tobias - Construction Executive
Research labs run experiments that can’t be paused. Hospitals treat patients around the clock. Yet these same facilities constantly need upgrades—new infrastructure, modernized systems, renovated spaces—to meet the demands of twenty-first century science and medicine. The challenge for construction teams isn’t just building. It’s building without ever turning the lights off. This unique dynamic creates an environment where construction activities are happening adjacent to sensitive testing and treatment, a complex setting where disruptions can have serious consequences. Skanska continues to successfully navigate these challenges across multiple sectors, including from occupied lab space at the North Carolina Department of Environmental Quality’s (NCDEQ) Reedy Creek Laboratory in Raleigh to hospital corridors alongside staff and patients in various hospital locations across the country.
