Fatalities Edge Down: New Data Reveals a Promising Decline

April 27, 2026 — Construction Executive
Construction fatalities in the United States declined slightly in 2024, according to new data released from the U.S. Bureau of Labor Statistics. The sector recorded just over 1,000 worker deaths last year—a modest decrease from the previous year but still among the highest totals of any industry. Falls remained the leading cause of death, accounting for roughly one-third of all construction fatalities. Transportation incidents—including workers struck by vehicles or equipment—ranked second, followed by contact with objects or equipment and electrocutions.

Humanoid Robots in Construction: The Reality Right Now

October 12, 2026 — Aarni Heiskanen - AEC Business
Humanoid robots are getting a lot of media attention. Videos of robots doing backflips and kung fu moves suggest that a general-purpose machine worker is just around the corner. A recent visit by the Finnish technology magazine Tekniikka&Talous to crane manufacturer Konecranes offers a more sober picture. I think it is a useful reality check for anyone in the AEC industry wondering what humanoids can actually do today. What a Humanoid Can Do in a Controlled Environment Konecranes bought a Unitree G1 EDU humanoid in autumn 2025, likely as the first Finnish industrial company to do so. With separately purchased five-finger hands and other extras, the price came close to €100,000. Read the full story...

Conditional Payment Bond Consideration-Make Sure There Is Pay-If-Paid Provision

June 29, 2026 — David Adelstein - Florida Construction Legal Updates
If a general contractor is going to have a conditional payment bond, it needs to ensure it subcontracts contain pay-if-paid or pay-when-paid provisions. This conditional payment language in subcontracts is the general contractor’s defense that it doesn’t have to pay a subcontractor UNTIL owner has paid the general contractor for the subcontractor’s work. The general contractor (and the surety) can look at the conditional payment bond with the s. 713.245 legend stamped on its face designating the conditional nature of the bond, and assume the conditional structure is locked in against the bond: no payment from the owner, no obligation to the subcontractors under the bond. But what happens when the subcontracts contain no express conditional payment language despite having a valid conditional payment bond? Read the full story...

New Law Prompts ABC Minnesota/North Dakota to Design New Telecommunications Safety Training Program

June 29, 2026 — Grace Calengor - Construction Executive
On the first day of the year, a Minnesota law requiring installers of underground telecommunication infrastructure broadband, fiber or phone lines (when projects utilize directional drilling, and/or work is being conducted within 10 feet of existing utilities) to undergo a 40-hour certification went into effect. Originally passed in mid-2024 and proposed to go into effect in July 2025, the law’s requirements were postponed until January 2026, giving ABC Minnesota/North Dakota—in partnership with NCCER and the Minnesota Cable Communications Association—time to roll out their Safety Qualified Underground Telecommunications Installer training program, which would ensure the workforce of their contractor members were certified.

LA Scores Major Victory in a High-Exposure Premises Liability Action

July 06, 2026 — Dolores Montoya - Bremer Whyte Brown & O'Meara LLP
Our firm is proud to announce a decisive defense victory obtained by Partner Daniel Crespo and Associate Lauren Landau for our client in a high-exposure premises liability action arising from a 2022 incident at an active school construction site in Perris, California. On March 10, 2026, the Riverside County Superior Court granted Summary Judgment in full for our client, dismissing all claims brought by Plaintiff, who alleged she tripped and fell over a curb while picking up her daughter from school and sustained ankle and wrist injuries as a result. Through meticulous preparation and the strategic use of construction plans, contractual documents, and onsite surveillance video evidence, our team demonstrated that our client had no ownership, possession, or control over the portion of the existing sidewalk where the incident occurred, with construction plans unambiguously designating the area as pre-existing concrete outside our client’s scope of work, and the Construction Services Agreement expressly reserving control over all existing site improvements to the school district.

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.

Understanding the EPA’s Latest Proposed Drinking Water Contaminant Monitoring Rule, Published in Law360

September 01, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) proposed Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) represents another step in the federal government’s ongoing effort to identify and evaluate emerging contaminants in drinking water. The proposal would require certain public water systems to monitor and report on 30 unregulated drinking water contaminants from 2028 through 2030, while generating occurrence data that could inform future regulation and affect environmental, commercial, litigation and risk assessments. In an article published by Law360, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, analyzes the scope and practical implications of UCMR 6, including the contaminants selected, the proposed monitoring requirements for public water systems, and the EPA’s continued focus on PFAS and related organofluorine compounds. The article also touches upon the potential significance of publicly available monitoring data for businesses and property stakeholders. Read the full story...
