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.

Could Your Project-Level AI Prompt Become the Other Side’s Smoking Gun?

October 20, 2026 — Ryan Glass - ConsensusDocs
A dispute is brewing on the project. Wanting a quick assessment, the project manager opens ChatGPT, Claude, or another generative artificial intelligence (“AI”) platform. The project manager types the dispute background into the prompt, including concerns, explanations, and a frank discussion of what may have gone wrong on the contractor-side. The AI response identifies potential weaknesses in the contractor’s position, including possible failures to meet contractual obligations. Unhappy with the answer, the project manager starts a new chat, revises the prompt, and tries again. If the dispute escalates to arbitration or litigation, can the owner force the contractor to provide these prompts and the resulting responses? Frustratingly, the answer is: it depends. Courts have reached different conclusions. For now, the safest course is to involve your counsel before using AI to evaluate a demand letter, default notice, or threatened lawsuit, or before using AI to draft dispute-related emails, claim letters, or other communications that contain project-specific facts. Otherwise, what feels like a private conversation may later become key evidence for the opposing party. Read the full story...

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.

One Year In: A Look at the Initial Impacts of LEED v5 on the Built Environment

October 20, 2026 — Eric Haggstrom - Construction Executive
As federal climate policies shift, the built environment has entered a period of uncertainty where developers, designers and owners need to find pragmatic, forward-looking approaches to sustainability. A year after its launch on April 28, 2025, LEED v5 is helping lead that charge by pushing the industry toward a stronger long-term focus on carbon reduction, climate resilience and building performance. The framework of this certification provides a snapshot of the current state of the industry and an indication of where it may be headed in the future. LEED v5’s introduction has helped to begin reframing and informing the approaches of both mission-driven and cost-conscious clients, providing a framework to align their decisions more closely with sustainable priorities by emphasizing carbon reduction, energy efficiency and electrification. These standards can help teams make investments strategically by phasing in upgrades, planning for future technologies and demonstrating how the rating system is influencing long-term decision-making across projects.

Voluntary Dismissal of an Indemnity Claim Does Not Make the Subcontractor a “Prevailing Party,” Washington Court of Appeals Holds

September 21, 2026 — Margarita Kutsin - Ahlers Cressman & Sleight PLLC
In King County v. Walsh Construction Company II, LLC, No. 86503-0-I (Wash. Ct. App. Aug. 4, 2025), an unpublished decision from Division I of the Washington Court of Appeals, the Court affirmed the denial of a subcontractor’s request for prevailing-party attorney fees under an indemnity clause after the general contractor voluntarily dismissed its indemnity claims. Because the indemnity claim was no longer live and no determination of fault had occurred, the Court held that the trial court did not err in denying the request. ACS represented Walsh, the general contractor, in securing the denial of the fee request at the trial court that the Court of Appeals affirmed. A Pass-Through Indemnity Claim That Ended Before Fault Was Decided The dispute arose out of a public works contract under which King County hired Walsh Construction Company II, LLC (“Walsh”) to construct and install a conveyance pipeline. After the pipeline broke, King County sued Walsh for breach of contract and warranty, expressly identifying both Walsh and its subcontractor, Mears Group Inc., (“Mears”) as responsible. Walsh tendered defense and indemnity to Mears under the subcontract. Read the full story...

New Florida Law Adds Licensing Risk to Contractor/Subcontractor Payment Disputes

September 29, 2026 — Brett J. Moritz & Ali Heyat - Peckar & Abramson, P.C.
Effective July 1, 2026, Florida’s newly enacted Section 489.1295 of the Florida Statutes, titled “Prohibition Against Nonpayment,” requires licensed contractors to timely compensate subcontractors and suppliers for labor, services, or materials. Enacted as part of Senate Bill 290 (Ch. 2026-3, Laws of Fla.), the statute adds a new basis for instituting disciplinary proceedings against a contractor’s license if a payment is knowingly or willfully withheld. While this is not a sweeping overhaul of Florida construction payment laws by any means, contractors should be aware that nonpayment disputes with subcontractors and suppliers may carry potential licensing consequences.
