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.

Actual Controversy Without Actual Exhaustion: California Supreme Court Allows Declaratory Relief and Bad Faith Claims Against Excess Insurers

August 24, 2026 — Kyle A. Rudolph - Saxe Doernberger & Vita, P.C.
California courts were previously split on the issue of whether an insured may bring declaratory relief claims against excess insurers prior to the exhaustion of underlying insurance. Some California courts held that the actual exhaustion of underlying insurance was necessary, whereas other courts allowed for these types of claims to proceed.[1] Recently, the California Supreme Court addressed this split of authority and, in doing so, handed down a significant win for policyholders. In Fox Paine & Company, LLC, et al. v. Twin City Fire Insurance Company et al., the Court held that insureds may proceed with bringing forth viable declaratory relief and bad faith claims against excess insurers prior to the exhaustion of underlying insurance.[2] A summary of the Court’s opinion is provided below.

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...

Travelers Injury Impact Report Highlights Longer Recovery Times Amid Declining Injury Rates

May 05, 2026 — The Travelers Companies, Inc.
HARTFORD, Conn.--(BUSINESS WIRE)--The Travelers Companies, Inc. (NYSE: TRV) today released its 2026 Injury Impact Report, an analysis of more than 1.2 million workers compensation claims received by the company from 2021 through 2025. The report finds that even as workplace injury rates decline, the injuries that do occur are growing more complex and taking longer to heal – a trend driven by an aging workforce and the disproportionate vulnerability of first-year employees. “The decrease in workplace injuries is a positive story, yet injured workers are still missing an average of 80 workdays,” said Claude Howard, Vice President of Workers Compensation Claim at Travelers. “This report is a reminder that progress doesn’t mean the risk environment requires any less attention, and an employer’s commitment to safety must keep pace with an ever-evolving workforce and injury landscape.” Read the full story...

Jurisdiction Over Foreign Manufacturers in Construction Litigation

May 14, 2026 — Timothy J. Repass & Miki J. Saito - Wood Smith Henning Berman
A recent decision from the Washington Court of Appeals provides important guidance on personal jurisdiction over foreign product manufacturers in construction and infrastructure litigation. In King County v. Aquatherm GmbH, No. 85572-7-I (Wash.Ct. App.Div.I)(unpublished), the court addressed whether a German manufacturer could be sued in Washington for alleged defects in piping used in major public infrastructure projects. The ruling offers a detailed, fact-driven roadmap for how Washington courts evaluate jurisdiction over foreign manufacturers operating through layered distribution networks. It also reflects a broader trend toward focusing on real-world commercial conduct rather than formal corporate structure. Background of the Case King County sued after widespread failures in polypropylene piping installed at the King County Correctional Facility. The pipe, manufactured by Aquatherm GmbH in Germany, was marketed, distributed, and installed through a network of U.S.-based entities. Following a six-week trial, the jury returned a verdict exceeding $18 million on claims under the Washington Product Liability Act and Consumer Protection Act. Aquatherm challenged, among other things, the trial court's exercise of personal jurisdiction. Reprinted courtesy of Timothy J. Repass, Wood Smith Henning Berman and Miki J.

Sometimes a General Damages Assessment is Enough. . .

July 06, 2026 — Christopher G. Hill - Construction Law Musings
It has been a while since I last posted here at Construction Law Musings. Life, law practice, and “blogger’s block” have taken their toll on the posting schedule. Hopefully this will be one of several upcoming posts now that the litigation schedule has lightened a bit over the summer. Today’s post is about damages. Specifically damage to a homeowner’s roof and her legal damages therefor. That last is of course a sentence that only a construction attorney (or other litigator) could possibly craft and have it make sense. Now, on with the case. . .In Hardesty Construction, Inc. v. Weedon, the facts are as follows: Ms. Weedon had hail damage to the roof of her home. She hired Hardesty Construction to repair and replace the roof. After the first roof was installed and failed inspection, a second roof was installed. The issue was that the first roof had a warranty and the second roof, installed similarly to the first (and allegedly with the same construction issues according to Ms. Weedon’s expert), was not provided with the promised warranty. As one may expect, Weedon sued Hardesty and Hardesty Construction for fraudulent inducement and breach of contract. At trial, Weedon testified, without objection, that her home was worth $40,000 less because of Hardesty Construction’s work, which was based partially on quotes Weedon received to fix the roof. The Circuit Court granted Hardesty Construction’s motion to strike Weedon’s fraudulent inducement claim, but not her other claims. A jury awarded Weedon $30,253.30 on her breach of contract claim. Hardesty Construction appealed, arguing the Circuit Court erred in (a) allowing the jury to consider Weedon’s valuation testimony because it was not based on her personal knowledge and (b) denying its motion to strike based on insufficient evidence as to damages. Weedon assigned cross-error in the Circuit Court’s decision to grant the motion to strike her fraudulent inducement claim against Samual Hardesty. Read the full story...
