Kahana Feld Obtains Favorable Result in High-Exposure NY Premises Liability Case

June 15, 2026 — Leigh Katz - Kahana Feld
Kahana Feld partner Leigh Katz obtained a significant victory in a recent matter involving a videotaped alleged trip and fall on the sidewalk in front of the client’s commercial residence. The plaintiff claimed he suffered a knee injury that necessitated surgery, along with other assorted injuries that prevented him from continuing high-level athletic activities. Leigh was able to demonstrate that the fall was staged and received a voluntary discontinuance with prejudice. At mediation, Leigh emphasized that KF’s expert witness challenged the plaintiff’s claim that the fall was caused by a sidewalk height differential after reviewing the videotape footage and determining the plaintiff’s fall began before his feet made contact with the alleged defect. Based on this analysis, the expert concluded the reported height differential did not initiate the fall, which supported KF’s position that the incident depicted in the video was unrealistic and appeared staged.

Supreme Court Rules Tariffs Unconstitutional: Why the Construction Industry Shouldn’t Expect Calm Just Yet

March 31, 2026 — Christopher Barnett - Construction Executive
The U.S. Supreme Court’s 6–3 decision in Learning Resources, Inc. v. Trump did what many expected: It held that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. What few anticipated was the speed of what followed: Within hours of the ruling, the administration announced replacement tariffs under Section 122 of the Trade Act of 1974, imposed a 10% global surcharge effective February 24, and signaled forthcoming Section 301 investigations against most major trading partners. For those in the construction industry hoping the Learning Resources ruling would restore market stability, the message was unambiguous. The constitutional question may be settled, but the market disruption is not. Reprinted courtesy of Christopher Barnett, Construction Executive, a publication of Associated Builders and Contractors.

How Mobile Tools Are Capturing Safety Data on Jobsites

April 08, 2026 — Michael Bruns - Construction Executive
Traditionally, construction safety management is “reactive compliance”—reporting on an incident, filling out a form on paper or electronically, taking a picture and filing it away for compliance purposes. Safety management is shifting from reactive to proactive. Forward-thinking companies are using data and leading indicators to identify risks before incidents happen, not just document injuries after the fact. Mobile tools have completely changed the way safety operations work on construction sites, enabling that transition to proactive safety management.

The Modern Nuclear Renaissance Reaches New England

April 14, 2026 — Stephen J. Humes - Gravel2Gavel Construction & Real Estate Law Blog
On March 31, 2026, the governors of all six New England states issued a joint, bipartisan statement committing the region to explore deployment of advanced nuclear energy technologies while supporting the continued safe, affordable and reliable operation of New England’s existing nuclear generation facilities. This coordinated regional initiative follows a major policy announcement in June 2025 by New York Governor Kathy Hochul directing the New York Power Authority to pursue development of at least 1,000 MW of advanced nuclear generation to support statewide reliability needs and New York’s zero‑carbon mission. Less than one year after New York formally embraced a modern nuclear renaissance, that renaissance has now expanded across the New England states—signaling a broader Northeast regional pivot toward nuclear as a core element of long‑term reliability, affordability and decarbonization strategies. For utilities and power generators, this shift creates both opportunities and planning imperatives that warrant immediate attention. Read the full story...

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.

Endra Rethinks MEP Design with AI

July 06, 2026 — Aarni Heiskanen - AEC Business
Niklas Lindgren, co-founder and CEO of Endra, joins the AEC Business Podcast to discuss why his Stockholm-based startup is rebuilding MEP design from the ground up with AI. Endra recently raised $50 million in Series A funding and counts some of the world’s largest engineering consultancies as customers. Niklas explains why Revit’s underlying data model is too coarse to support deep automation, and why Endra built its own granular 3D data model instead of working as a plugin. He describes Endra’s “spatial AI” approach to routing conduit and ductwork without clashes, and how the platform models entire electrical systems, from receptacle to transformer, inside a single source of truth.

Contract Disputes Act and Jurisdictional Requirements

March 17, 2026 — David Adelstein - Florida Construction Legal Updates
When dealing with a claim on a federal construction project, there are a couple of key background jurisdictional points. These points were briefly highlighted in the recent appeal, Mega Star Logistics Service Co. v. Department of State, CBCA 8232, 2026 WL 253738 (CBCA 2026). Here are the two points. FIRST, when it comes to jurisdiction, for a board of contract appeals “to exercise jurisdiction over a claim, the CDA [Contract Disputes Act] requires the contractor to submit a written claim to the contracting officer for a COFD [contracting officer final decision], with a subsequent appeal of the COFD or deemed denial if the CO [contracting officer] does not issue a COFD.” Thus, you need to submit a formal claim under the Contract Disputes Act to the contracting officer to get a final decision from the contracting officer (or the contracting officer waiving the final decision by not timely furnishing one).
