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 Architects Who Dream of a New Stone Age

October 26, 2026 — Jennifer Hahn – Bloomberg
Most of the world’s longest-standing buildings have one thing in common: They are made from stone. Still, you’d be hard-pressed to find this civilization-outlasting material as a structural element in modern construction. Many stone buildings are imposters: thin veneers of limestone or granite disguising concrete and steel skeletons. In its day job as Earth’s crust, stone is currently holding up entire cities, countries and continents. But it’s rarely used to its full potential as a load-bearing material that can be stronger than concrete. Read the full story...

What Massachusetts Contractors and Developers Can Learn from Cannistraro v. Columbia Construction

July 13, 2026 — Anthony LaPlaca & Luke Marston - The Construction Seyt
Introduction On June 26, 2026 the Massachusetts Supreme Judicial Court issued its decision in J.C. Cannistraro, LLC v. Columbia Construction Co.—a holding that sits at the intersection of Prompt Pay Act compliance and the Massachusetts Arbitration Act.[1] Most already know that the Massachusetts Prompt Pay Act (PPA) imposes strict timing and certification requirements for rejecting payment applications and proposed change orders on projects valued at $3 million or more. Most notably, the PPA requires the paying party to give the payee written notice of its approval or rejection of progress applications and proposed changes within 15 days of receipt, which notice must include a “factual and contractual basis for the rejection” and must be “certified as made in good faith.”[2] In the absence of a timely certified notice, payment is “deemed to be approved” unless the payor properly rejects payment before it comes due.[3] Reprinted courtesy of Anthony LaPlaca, Seyfarth Shaw LLP and Luke Marston, Seyfarth Shaw LLP Mr. LaPlaca may be contacted at alaplaca@seyfarth.com Mr. Marston may be contacted at lmarston@seyfarth.com Read the full story...

That’s a Wrap! Pennsylvania Court Holds Arbitration Clause in Online Agreement Unenforceable

May 14, 2026 — Gus Sara - The Subrogation Strategist
In Duffy v. Tatum, 2026 Pa. Super. LEXIS 112, 2026 PA Super 41, the Superior Court of Pennsylvania (Superior Court) considered whether an arbitration provision contained in the online Terms of Service on the defendant’s website were enforceable. The plaintiff, Daniel Duffy (Duffy), visited the website of defendant, Dolly, Inc. (Dolly), to purchase moving services. Duffy selected the number of movers, items to be moved and the type of vehicle needed. To complete the booking, the website required Duffy to checkmark a box labeled “By checking this box I accept the Dolly Terms of Service.” Duffy did not have to open the link or scroll to the bottom of the agreement before being able to click on the checkmark box. The Terms of Service included an arbitration provision requiring that any dispute related to the moving services to be resolved by arbitration in accordance with the American Arbitration Association. The Terms of Service did not include any statement that the user was waiving the right to a jury trial. The Superior Court found the internet Terms of Service unenforceable. During the moving process, an accident occurred and injured Duffy. In May 2024, Duffy and his wife sued Dolly and other related entities alleging negligence and loss of consortium. Dolly filed preliminary objections alleging that the parties agreed to alternative dispute resolution. The lower court overruled the preliminary objections, finding that Dolly’s website did not provide reasonably obvious notice of its Terms of Service to Duffy and, as such, Duffy never agreed to waive his constructional right to a jury trial. Dolly filed an appeal to the Superior Court. Read the full story...

Colorado’s New Mechanics’ Lien Protections: What S.B. 26-074 Means for Your Next Project

October 27, 2026 — Maria Conversa - Snell & Wilmer
Starting August 12, 2026, Colorado’s mechanics’ lien statute underwent its most significant update in years. Colorado’s General Assembly enacted Senate Bill 26-074 on April 6, 2026, and the new law directly addressed a problem that has plagued contractors and subcontractors for decades. For years, a contractor and subcontractor who filed a lien for the full amount it believed was due — particularly when that amount included disputed costs, delay damages, or lost productivity — risked triggering the “excessive lien” penalty. That penalty could force the claimant to forfeit its lien rights entirely and pay the other side’s attorney fees. The new law expands the categories of costs to be claimed by good-faith lien claimants, while still protecting against truly abusive filings. General contractors, subcontractors, suppliers, owners, and lenders all need to understand these changes. What the Bill Changed 1. Lien Value May Include Disputed Amounts The bill amends the core lien statute to insert the phrase “whether disputed or undisputed” into the description of lienable value. Prior law referenced only “the value” of labor, services, or materials furnished. The new text confirms that a lien can attach for amounts the parties still dispute. A claimant no longer needs the owner or general contractor to agree on the amount before filing. Read the full story...

Differing Site Conditions Claim Requires a Misrepresentation

May 14, 2026 — David Adelstein - Florida Construction Legal Updates
If you are entertaining a differing site conditions claim, consider this Third District Court of Appeals case from the mid-90s. In Hendry Corp. v. Metropolitan Dade County, 648 So.2d 140 (Fla. 3d DCA 1995), a contractor was hired by Dade County to demolish the old Rickenbacker Causeway in Miami. The original 1941 plans of the causeway were made available to contractors. The lowest bidding contractor that was awarded the project based its bid “on its conclusion that the pilings supporting the old bridge were made of concrete.” Hendry, supra at 141. The contractor based this conclusion on the original plans, its visual observation, and experience. Read the full story...
