In AECOM Tech. Servs., Inc. v. Flatiron | AECOM, LLC, 2024 WL 22640 (D. Colo. 2024), the United States District Court for the District of Colorado addressed when expert testimony is not subject to be limited or excluded pursuant to Federal Rule of Evidence 702. Background In 2015, AECOM Technical Services, Inc. (“AECOM”) and Flatiron | AECOM, LLC (“Flatiron”) entered into an agreement, in which they agreed to work together to assemble a design/build team for the purposes of submitting a proposal to the Colorado Department of Transportation’s (“CDOT”) construction project known as C-470 Tolled Express Lanes Segment 1 Design-Build Project (the “Project”). AECOM provided the design and engineering services, and Flatiron submitted the proposal to CDOT. On or about June 16, 2016, CDOT awarded Flatiron the Project. Flatiron later claimed that AECOM’s design failed to follow basic engineering and project requirements. Read the full story...

Alert: Fraudulent Notice of Nonpayment Defense Applies to Payment Bond Claims

April 27, 2026 — David Adelstein - Florida Construction Legal Updates
Under Florida’s Lien Law, there’s an affirmative defense or affirmative claim known as a “fraudulent lien.” The fraudulent lien defense or claim is set out in Florida Statute s. 713.31. This defense also extends to payment bond claims, whether under a private statutory payment bond (Florida Statute s. 713.23) or a public payment bond (Florida Statute s. 255.05), as it pertains to the notice of nonpayment. A notice of nonpayment needs to be served within 90 days from final furnishing to preserve a claimant’s rights against the bond. However, there really has not been a case, until now, that discusses a “fraudulent notice of nonpayment.” In K&M Electric Supply, Inc. v. Brown Electrical Solutions, LLC, 51 Fla.L.Weekly D672a (Fla. 4th DCA 2026), a prime contractor and surety prevailed at the trial level on their fraudulent notice of nonpayment defense based on a supplier’s notice of nonpayment and action against a public payment bond (under Florida Statute s. 255.05).

U.S. Supreme Court Decision May Negate State Law Requirement to File a Certificate of Merit with the Complaint in a Federal Action Against a Design Professional

April 27, 2026 — Christopher Olsen & Phillip Boldt - ConsensusDocs
To deter frivolous and unfounded claims against design professionals, states throughout the country have enacted statutes which generally require litigants to furnish a formal certification of merit (“COM”) from a qualified expert or face potential dismissal of their lawsuit. These COM statutes can impose a significant front-end burden on claimants who must pay an expert to review project records, interview the project team, and prepare a formal report before the lawsuit can be filed—often regardless of the amount in controversy. However, in light of a recent U.S. Supreme Court decision in a medical malpractice case, most, if not all of these statutes, may no longer be enforceable in federal court. This article examines the recent decision in Berk v. Choy, 146 S. Ct. 546 (2026), the decisions thus far which have applied Berk to invalidate COM statutes, and other categories of statutes applicable to the construction industry which may face a similar fate. The U.S. Supreme Court Decision (Berk v. Choy) In Berk, the plaintiff, Harold Berk, sued a doctor for medical malpractice under Delaware law in Delaware federal court. 146 S. Ct. at 551. Under Del. Code, Tit. 18, § 6853(a)(1), an affidavit of merit (like a COM) must accompany a complaint alleging medical malpractice. Id. Berk failed to include an affidavit of merit with his complaint. Id. at 552. Applying Delaware state law, the federal court dismissed Berk’s medical malpractice claim. Berk appealed to the Third Circuit, arguing that the affidavit of merit required by § 6853(a)(1) is unenforceable in federal court because it is more onerous than the Federal Rules of Civil Procedure. The Third Circuit affirmed the District Court’s ruling, finding § 6853(a)(1) enforceable in federal court.

The Single Source of Truth in Construction Projects: Reality or Myth?

March 24, 2026 — Aarni Heiskanen - AEC Business
The idea of a single source of truth has been a fundamental part of the digital vision in the AEC industry for many years. From centralized CAD storage to BIM collaboration platforms and, more recently, Common Data Environments, the goal stays the same. Project teams want a reliable place where everyone can access the latest information. The phrase “single source of truth” comes from database and information management practices in the IT world, where the goal was to maintain one authoritative record of data and eliminate data redundancy. As the AEC industry began adopting digital tools, the same idea was applied to project information and workflows. Despite decades of technological progress, the question remains whether “one ring that rules them all” can actually be implemented in real construction projects. Read the full story...

EPA Steps Back, Arizona Moves Forward

May 12, 2026 — Patrick J. Paul, John Habib & Sukhmani K. Singh - Snell & Wilmer
In a significant development for Arizona’s business community and environmental policymakers, the U.S. Environmental Protection Agency (EPA) has paused its planned reclassification of Maricopa County from “Moderate” to “Serious” ozone nonattainment status pursuant to the Clean Air Act’s National Ambient Air Quality Standards (NAAQS). This decision marks a shift in federal air policy — one that recognizes the unique challenges faced by regions like metro Phoenix, where environmental conditions beyond local control are often key contributors to air quality readings. The EPA’s move follows a series of meetings between EPA Administrator Lee Zeldin, Arizona elected officials, and business and civic leaders, including a recent roundtable in Phoenix convened by U.S. Senator Mark Kelly. In announcing the pause, Zeldin acknowledged the need for flexibility and fairness in the application of Clean Air Act standards, especially when emissions from other states, nations, and natural events significantly influence local air quality.

December 30, 2025 — Skylar Woodhouse - Bloomberg
President Donald Trump has tapped a new architect to help plan his $300 million White House ballroom wing, assigning the former lead designer to a consultant role in the high-profile and controversial project. Shalom Baranes Associates, a Washington-based architecture firm, will design the ballroom that will be built in place of the demolished East Wing, according to a White House official. James McCrery, who was previously named to lead the project, will remain in a consulting role. “Shalom is an accomplished architect whose work has shaped the architectural identity of our nation’s capital for decades and his experience will be a great asset to the completion of this project,” White House spokesman Davis Ingle said.

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.
