Research Illuminates Pollution Problem in Tijuana River Valley

June 29, 2026 — Jeff Yoders - Engineering News-Record
The Tijuana River watershed between southern California and northern Mexico has been the epicenter of an environmental and public health crisis for more than two decades. Since October 2023 alone, more than 31 billion gallons of raw sewage and polluted water have flowed into the U.S. and, eventually, the Pacific Ocean. Read the full story...

Federal Court Finds that Master Agreement Bestows Additional Insured Coverage

November 09, 2026 — Craig Rokuson - Traub Lieberman
In the recent case Triborough Scaffolding & Hoisting Servs. v. Sw. Marine & Gen. Ins. Co., 2026 U.S. Dist. LEXIS 226876, Judge P. Kevin Castel, who was also operating as finder of fact, held that a subcontractor master agreement covered a subcontractor’s work at a specific project, such that an obligation to name the prime contractor Triborough as well as the undefined Owner, bestowed additional insured coverage to Triborough and the Owner under policies issued to the subcontractor. The agreement at issue was dated December 15-16, 2017 and the accident at issue occurred in 2018. The trial evidence includes testimony from both Triborough and the subcontractor that the agreement was intended to apply annually, and the subcontractor could not recall the parties ever signing a project-specific agreement. Further, Triborough assigned work to the subcontractor by telephone call or texts on several projects, and without a project-specific contract. Moreover, no other operative indemnity or insurance agreement between Triborough and the subcontractor, other than a backdated agreement that was not applicable. Finally, the court did not find plausible that the subcontractor would enter into an agreement meant only to cover the final two weeks of 2017, such that the agreement extended into work occurring in 2018.

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...

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...

Building the Research and Healthcare Facilities of Tomorrow Without Impacting the Progress of Today

August 16, 2026 — Jason Tobias - Construction Executive
Research labs run experiments that can’t be paused. Hospitals treat patients around the clock. Yet these same facilities constantly need upgrades—new infrastructure, modernized systems, renovated spaces—to meet the demands of twenty-first century science and medicine. The challenge for construction teams isn’t just building. It’s building without ever turning the lights off. This unique dynamic creates an environment where construction activities are happening adjacent to sensitive testing and treatment, a complex setting where disruptions can have serious consequences. Skanska continues to successfully navigate these challenges across multiple sectors, including from occupied lab space at the North Carolina Department of Environmental Quality’s (NCDEQ) Reedy Creek Laboratory in Raleigh to hospital corridors alongside staff and patients in various hospital locations across the country.

Preventing Common and Costly Water Intrusion Events in Construction

July 13, 2026 — Andrew Swift - Construction Executive
Water leaking into a building is a leading cause of damage and loss in the construction industry. On one jobsite, heavy rains flooded a sub-basement, damaging a new electrical transformer—all because a roof drain was not property connected. On another jobsite, a drinking-fountain supply line broke in a multistory building that was undergoing renovation, causing water to run—undetected—for an entire weekend, resulting in water damage to all lower floors, where construction had been finished. Those loss scenarios could have been prevented with a comprehensive and effective water damage prevention plan (WDPP). This includes routine site inspections to identify uncontrolled water damage exposures and basic maintenance to make sure drains are clean of debris and divert them to a catch basin or low point away from the building. An effective WDPP plan also incorporates technology such as backflow preventers on sewer connections and water sensing technology to monitor the most vulnerable exposures.

Seattle’s Residential Zoning Transformation: What Property Owners, Buyers, and Investors Should Understand

May 14, 2026 — Lawrence S. Glosser - Ahlers Cressman & Sleight PLLC
Seattle is in the midst of a significant transformation in residential land use policy. Longstanding neighborhood zoning patterns that historically favored detached single-family development are being reexamined in response to housing supply pressures, affordability concerns, and evolving state mandates. For homeowners, purchasers, investors, and builders, these changes may create substantial new opportunities. They also create a heightened need for careful legal and practical due diligence. While zoning reform can expand potential uses of property, it does not eliminate the many other constraints that may still govern what can actually be built. Read the full story...
