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...

Document Everything! Always! No Exceptions! (AKA, Help Your Lawyer Help You!)

April 14, 2026 — Melissa Dewey Brumback - Construction Law in North Carolina
I had a case last year in which once again I found myself thinking: if only my client had better documented the verbal agreements, we would have had a much easier time defending his work. I know this is often easier said than done— you are in the middle of building a project, and you get a call, and you need to keep the project moving. No time for written change directives or a special bulletin. And yet—it is simply amazing to me the number of people who develop “litigation amnesia” about things when a lawsuit is involved. Your documentation system does not need to be perfect. You can use a simple Field notebook and handwritten notations. A text memo to yourself or, better yet, an email confirmation to the owner/contractor/whoever. Read the full story...

Course of Construction Exclusions and the CGL Policy

July 20, 2026 — Anna M. Perry, Rachel S. Kindseth & Nina Catanzaro - Saxe Doernberger & Vita, P.C.
I. Course of Construction Exclusions Course of Construction (“COC”) exclusions are found on General Liability and excess liability policies, typically a wrap-up or project specific policy, and generally exclude “all property damage occurring during the course of construction.” Insurers claim COC exclusions are not problematic because they are intended to prevent an overlap in coverage between the general liability policy and first-party property Builder’s Risk policy. However, because General Liability policies and Builder’s Risk policies provide coverage for different risks, COC exclusions can create a gap in coverage for owners and contractors. Therefore, any exclusion on a wrap-up or project specific policy that limits coverage for property damage liability should be scrutinized, and amendments sought when warranted and commercially achievable, for owners, developers and contractors because General Liability policies do not cover the same risk as that of a Builder’s Risk policy. General liability policies provide defense and indemnity to the insured(s) for claims made by a third-party against the insured. Broad COC exclusions serve to preclude coverage for all property damage, not just property damage to the insured project. This includes property damage to property other than the insured project, e.g. an adjacent property. On the other hand, Builder’s Risk policies provide first-party property coverage for direct physical loss to the project during the course of construction. The Builder’s Risk policy will not provide coverage for property other than the project itself (e.g., adjacent property) and it will not provide a defense or indemnity in the event the owner of the damaged property brings a claim against a potentially at-fault party.

Pay-If-Paid: What You Need to Know Before Signing on the Dotted Line

August 03, 2026 — Christian Fernandez & Matthew Racioppo - Snell & Wilmer
Buried deep in the fine print of a subcontract, a pay-if-paid clause may be looming. If you are a subcontractor or supplier, misreading these clauses can put your cash flow at risk. If you are an owner or general contractor, drafting them incorrectly can leave you with obligations you never intended — or unenforceable protections you were counting on. It is more important than ever to understand when pay-if-paid clauses hold up and when they do not, as well as recent litigation and drafting trends. Whether you are negotiating a new agreement, reviewing your standard form contracts, or staring down a payment dispute, understanding how Arizona law treats pay-if-paid clauses is essential. In this article, we break down key considerations, walk through the legal standards Arizona courts apply, and offer practical tips to consider to help you protect your payment rights on the next project.

Presumption of Prejudice Applies to All Affirmative Defenses Regarding Insured’s Failure to Comply with Post-Loss Policy Conditions

June 23, 2026 — David Adelstein - Florida Construction Legal Updates
n a recent property insurance coverage dispute, an issue on appeal pertained to the “prejudice” jury instruction associated with the insured’s failure to comply with post-loss policy conditions. The trial court found that the prejudice only pertained to prompt notice and not other post-loss policy conditions. This was reversed on appeal as prejudice applied to ALL the post loss policy conditions that the insured failed to comply with, not just the prompt notice requirement. The prejudice presumption applies to all affirmative defenses regarding an insured’s failure to comply with post-loss policy conditions. Consider this discussion when dealing with an insurer raising prejudice as an affirmative defense to do an insured’s failure to comply with post-loss policy conditions, and the associated burdens of proof: On appeal, [the insurer] contends the trial court erred by instructing the jury that the presumption of prejudice was inapplicable to all of its post-loss obligation defenses except prompt notice. We agree. Read the full story...
