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...

The Deadline to File Suit on a Public Works Payment Payment Bond is Triggered by a Claimant’s Work on a Project Not by a Claimant’s Work Under a Contract

June 02, 2026 — Garret D. Murai - California Construction Law Blog
California law requires that prime contractors furnish a payment bond – providing for payment to lower-tiered subcontractors and suppliers – on state and local public works projects with a value in excess of $25,000. There are three conditions that must be satisfied when a claimant makes a claim against a payment bond on a public works project in California:

First, generally, the claimant must have served a preliminary notice, unless the claimant is a first-tier subcontractor or supplier;
The claimant must have “ceased to provide work” on the project; and
The claimant must file suit against the payment bond no later than six (6) months after the period in which a stop payment notice must be given or, in other words, the earlier of 270 days after completion of the public works project or 210 days after a notice of completion or cessation was recorded on a public works project.

In Tarlton & Sons, Inc. v. Great American Insurance Company, 111 Cal.App.5th 376 (2025), the 2nd District Court of Appeal examined whether a subcontractor timely filed a claim against a payment bond when a prime contractor was terminated and replaced by another prime contractor who the subcontractor continued to perform work for.

Supply Chain Is a Legal Exposure—Not Just a Force Majeure Problem

September 08, 2026 — Owen Newman - Construction Executive
This is not another force majeure article. The supply-chain related legal exposure that contractors are carrying today—in sanctions risk, specification non-compliance, warranty exposure and regulatory volatility—extends well beyond what even a well-drafted force majeure clause protects. An engineering, procurement and construction contractor on a gas-fired power plant discovers during commissioning that transformer oil in a critical unit contains Russian-origin naphthenic base oil, which is a prohibited source under Office of Foreign Assets Control sanctions. The contractor didn’t source it. A subsupplier two tiers below made the substitution when disruptions in the Strait of Hormuz tightened the primary supply chain for this specialty product and no one in the purchase-order chain flagged it. The procurement decision is long done and the documentation trail that should have caught it doesn’t exist.

Trend Continues Where Unlicensed Contractors Have No Recourse

July 13, 2026 — David Adelstein - Florida Construction Legal Updates
There’s been a recent trend in Florida case law that has figuratively “killed” unlicensed contractors. Here’s another one. The moral to this trend and case is simple: make sure you have the proper licenses prior to serving as a contractor under Florida law. Trying to be cute, as seemed to be the situation in this case with a creative argument, is not an argument that will carry the day and your resources will be devoted to being creative versus the ultimate merits of the dispute. In Ramindesign, LLC v. Skarzynski, 2026 WL 1649571 (S.D.Fla. 2026) an owner of real property hired a company to design and construct a spec home on the property. The company and its owner were NOT licensed contractors. The contract stated the company was serving as a “spec developer” and referred to it as the contractor throughout the contract. Other than this, the contract was set up as a cost plus a fee. Read the full story...

Not Every Job Is Worth Winning: Contract Risk Questions Contractors Should Ask Before They Bid

September 29, 2026 — Jack Mayo - ConsensusDocs
Introduction Winning the work is not the same as winning the project, at least financially. Consider a contractor that commits to procure custom or long-lead materials before receiving complete construction documents. Depending on the language of the contract, if the final design is altered after those materials have been ordered, the contractor may be left responsible for replacement costs, procurement delays, or both. Alternatively, a subcontractor that accepts a pay-if-paid provision without investigating the owner’s financing, or prematurely waives lien rights, potentially risks nonpayment for properly performed work. Such concessions can quickly transform an apparently profitable project into a significant financial burden. A successful bid can therefore become an unsuccessful project if the contractor accepts contractual “red flags” without evaluating their consequences and the long-term financial impacts that they may have. The significance of each risk will depend on the project, the parties, the proposed contract, applicable law, and the contractor’s business objectives. Although not comprehensive, this article identifies several key considerations for that process to help mitigate certain risks. 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.
