Urban Digital Twins: How Virtual Cities Could Help Build Smarter Cities

August 11, 2026 — Gravel2Gavel Construction & Real Estate Law Blog
Traffic congestion, endless construction, flooded streets and power outages. For city leaders and residents alike, these disruptions are simply part of daily urban life. But an emerging tool, known as the urban digital twin, could help cities anticipate problems before they occur by allowing planners to simulate responses, stress-test infrastructure, and evaluate decisions before implementing them in the real world. What Is an Urban Digital Twin? An urban digital twin is a dynamic, data-driven virtual model of a real city. It uses AI analytics and combines 3D modeling with real-time data and information from sources such as IoT sensors, traffic cameras, satellite feeds, infrastructure databases, utility networks, and environmental data including weather systems and heat maps to create a continuously updated digital representation of the urban environment that mirrors infrastructure, movement and systems in real time. In other words, it is a living digital replica of a city. Read the full story...

Lost in Translation: AEC Tech’s Missing Role

May 12, 2026 — Aarni Heiskanen - AEC Business
I once visited a construction site where the contractor’s headquarters had commissioned a tech company to build an on-site quality-inspection application. The developer had admitted to the site engineer that they had never set foot on a construction site before. The engineer showed me what he was actually using: his own phone camera and an Excel sheet. The new app did not map to how work actually happened on site. This is not an isolated story. The vendor builds something technically coherent but operationally disconnected. The client, somewhere up the chain, had fallen in love with the idea of the solution before anyone had built an honest business case for it. The result is a tool that gets demonstrated at a board meeting but isn’t used in the field. Read the full story...

Congratulations to BWB&O’s Orange County Team for Securing a Strong MSJ Result in a Residential Gas Explosion Matter!

May 14, 2026 — Dolores Montoya - Bremer Whyte Brown & O'Meara LLP
Huge Congratulations to Partner Kevin Wheeler and Associate Lindsey Wells for securing a strong result on a Motion for Summary Judgment / Summary Adjudication filed on behalf of their client, the City of Murrieta. This was a complex, multi-party matter arising from a residential gas leak and explosion, where Plaintiffs alleged the City and MFPD failed to properly respond to the incident. After multiple complaints were consolidated and extensive defense work narrowed the case, eighteen plaintiffs remained asserting five causes of action against the City, prompting a comprehensive MSJ/MSA targeting liability, causation, and damages. The Court’s ruling reflects a significant win, particularly on the immunity framework. The Court eliminated the core negligence and assumed-duty claims arising from fire protection and emergency response activities. It further disposed of the misrepresentation and public nuisance claims. At the end of the day, three plaintiffs were dismissed entirely for failure to comply with Government Claims Act requirements, further reducing the scope of the case. While the dangerous condition claim remains, it does so in a very limited posture. Read the full story...

D.C. Circuit Upholds EPA’s CERCLA Hazardous-Substance Designations for PFAS as State-Law Settlements Highlight Expanding Liability Landscape

September 15, 2026 — Ashleigh K. Myers, Amanda G. Halter, Jillian Marullo & Anthony B. Cavender - Gravel2Gavel Construction & Real Estate Law Blog
On August 18, 2026, a unanimous panel of the U.S. Court of Appeals for the D.C. Circuit upheld the 2024 designation by the U.S. Environmental Protection Agency (EPA) of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). (See Chamber of Commerce of the United States of America, et al. v. EPA, No. 24-1193 (D.C. Cir. Aug. 18, 2026).) The decision leaves EPA’s PFOA and PFOS hazardous substance designations in place and provides guidance on the scope of EPA’s authority to make future hazardous substances designations under CERCLA Section 102(a). The decision also likely resolves a challenge to the rule that has spanned two presidential administrations. After taking office, the Trump administration had obtained an abeyance of the litigation challenging the Biden-era rule while EPA reconsidered its position. In September 2025, EPA informed the court that it had decided to retain the designations, while signaling that it would work with Congress and industry to address CERCLA liability concerns for “passive receivers.” The litigation then resumed, with the current Administration defending the rule.

For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

Doctrine of Substantial Performance When It Comes to Payment

July 27, 2026 — David Adelstein - Florida Construction Legal Updates
A recent non-construction case touches upon the doctrine of substantial performance when it comes to payment. In this case, a club was to make two payments to secure a rapper’s attendance. The first payment was made. The second payment was made but was a few hundred dollars short of the agreed amount. The rapper did not show up. The club claimed it substantially performed its obligations. At first glance, the argument makes sense because the second payment fell only a few hundred dollars short. But that wasn’t the case when it comes to pre-commencement payment obligations:

Substantial performance applies only when the variance from the contract terms “is inadvertent or unintentional and unimportant so that the work actually performed is substantially what was called for in the contract.” However, when one party agrees to pay the other on or before a specific date, time is of the essence, and the payor is required to pay the payee on or before that date. “There is almost always no such thing as ‘substantial performance’ of payment between commercial parties when the duty is simply the general one to pay. Payment is either made in the amount and on the date due, or it is not.”

Big Gate Records, LLC v. Washington, 51 Fla.L.Weekly D1281a (Fla. 2nd DCA 2026) (internal citations omitted).
