Why and When Construction Robotics Makes Sense

February 10, 2026 — Aarni Heiskanen - AEC Business
In construction, robotics is often discussed in terms of technology: better AI, more capable machines, and robots on job sites. Recent research suggests that the question is less about whether robots can work and more about when and why they deliver real value. An Aalto University research paper on computer-vision-driven robotic waste sorting offers a valuable lens into this. The researchers use ZenRobotics’ computer-vision-enabled automated system as a case study. The Finnish startup was acquired by Terex, a U.S. company, in 2022. At first glance, waste sorting might seem like a niche application. But it illustrates a broader economic logic that aligns with findings across the broader body of research on construction robotics.

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.

Settlement Agreements and Contracts Require a Meeting of the Minds

July 20, 2026 — David Adelstein - Florida Construction Legal Updates
A settlement agreement does not need to be executed for it to be enforceable as long as there was a MEETING OF THE MINDS. The same rings true for any contract regardless of whether the contract is signed – THERE NEEDS TO BE A MEETING OF THE MINDS. In a recent case dealing with the settlement agreement on a construction lien, the essential settlement terms (money and mutual release) were memorialized in an e-mail exchange between the parties (owner and subcontractor). The settlement required the owner to pay the principal amount plus some attorney’s fees and then a mutual general release would be prepared. In response to the confirmatory email, the owner sent a check, which the subcontractor deposited, but the owner refused to sign the release signed and sent by the subcontractor. The owner further claimed it doesn’t need to pay the attorney’s fees because the lien amount was paid in full. The subcontractor sued arguing the owner breached the terms of the settlement. The appellate court agreed. Read the full story...

Leaders in Dispute Resolution Need to Make Unbiased Decisions for Mediation to Succeed

March 31, 2026 — Rick G. Erickson - Snell & Wilmer
As a mediator helping to settle construction disputes and as an arbitrator deciding outcomes of these disputes, I found certain lessons to be especially helpful after graduating last summer from the Executive Education program at Harvard Kennedy School (HKS). The exceptional HKS curriculum included courses focused on negotiation strategies for multiparty disputes, decisive leadership during crisis, and human behavior affecting dispute resolution. In particular, our HKS class debated the impact of cognitive bias in dispute resolution, and we studied a central theme that decision-making is universally scientific. That is, parties making decisions in dispute resolution exhibit and rely upon empirical factors that good mediators and decision makers should appreciate and understand. Bias, for example, can cause key players to discount persuasive witnesses, admissible evidence, and reliable expert opinions that influence the outcome of a construction dispute. Biased decision makers may also choose to withhold key information from the mediator, as though doing so will help rather than hurt what is supposed to be an objective and diplomatic process.

Daily Journal Publishes Article by Brenda Radmacher on Proposed Overhaul of California Construction Defect Law

June 29, 2026 — Brenda Radmacher - The Construction Seyt
Daily Journal (California) featured an article by Construction Law partner Brenda Radmacher, “A new path for construction defects in California.” The piece, published on June 15, 2026, examines Assembly Bill 1903 and its potential to significantly reshape California’s construction defect framework, particularly for common interest properties. The article highlights how AB 1903 would overhaul the state’s current right-to-repair system by mandating completion of prelitigation procedures, raising requirements for defect claims, strengthening developers’/builders’ rights to repair, and introducing a voluntary “certified building” program. The legislation aims to rebalance competing interests by reducing litigation-driven costs while preserving protections for homeowners. Read the full story...

Only A Contractor Can Appeal a Contracting Officer’s Final Decision

April 20, 2026 — David Adelstein - Florida Construction Legal Updates
A recent decision from the Civilian Board of Contract Appeals confirms that “only a ‘contractor’ may file an appeal of a contracting officer’s final decision.” Wattiker v. General Services Administration, 2026 WL 846001 (CBCA 2026) (citation omitted). The term “contractor is not an ambiguous term. A ‘contractor’ refers to a party to a federal government contract. Wattiker (citing the Contract Disputes Act). This is why the Contract Disputes Act does not apply to parties that are NOT in contract with the federal government. Id. In Wattiker, an appellant (appealing party) challenged the dismissal of a co-appellant. The co-appellant was dismissed because he was not a contractor, i.e., a party in contract with the federal government. In other words, the co-appellant had no privity of contract with the federal government. 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.
