Emerging Issues in Construction CGL Insurance Part 2: The Separation of Insureds and Additional Insured Interests

September 29, 2026 — Eric M. Clarkson - SDV Fenchurch
Many coverage disputes hinge on first principles—the fundamentals of insurance —rather than the minutiae. Unfortunately, the basic anatomy of insurance policies can get lost sometimes when parties are laser-focused on a particular term or set of circumstances. This is true not just in disputes, but also when writing coverage. One of the fundamentals that is commonly misunderstood and overlooked—but which is absolutely critical to the intended operation of insurance coverage—is what is commonly known as the “separation of insureds.” The “separation of insureds” is the concept that each “insured” under a policy are referred to and treated differently, and most of all that the distinctions matter. The concept is usually included as a condition in the policy. It embodies the requirement that the policy applies to each insured distinctly from how it applies to other insureds. The ISO Form CGL policies specifically state that they apply “[s]eparately to each insured against whom a claim is made or ‘suit’ is brought.” The separate and distinct treatment of insureds is more critical in construction operations than anywhere else. This distinction is essential to ensure coverage works as intended, especially when contracted operations are involved, because the policy must insure the subcontractor that purchased the policy, the general contractor who hired the subcontractor, and the owner that hired the general contractor. Even small modifications can easily frustrate the intent of the parties. Read the full story...

Ahlers Cressman & Sleight is pleased to announce its leading recognition in the 2026 Washington Super Lawyers magazine. With ten members named, ACS has more recognized Construction Litigation attorneys than any other firm on the 2026 Washington Super Lawyers list, compared to three at the next closest firm. Two ACS members were also recognized on the 2026 Washington Rising Stars list. Super Lawyers selects these recognized lawyers by using a patented multiphase selection process. First, lawyers enter the candidate pool by being nominated by their peers or by being identified by managing partner surveys, third-party feedback, or the Super Lawyersresearch team. Next, Super Lawyersconducts an independently researched evaluation using twelve indicators of professional achievement and peer recognition: verdicts/settlements, transactions, representative clients, experience, honors/awards, special licenses/certifications, position within a law firm, bar and/or professional activity, pro bono and community service, scholarly lectures/writings, education/employment background, and other outstanding achievements. Then, candidates with the highest point totals serve on a Blue Ribbon panel, evaluating other candidates within their primary practice area. Finally, only 5% of attorneys are selected for the Super Lawyers list, and 2.5% of attorneys are selected for the Rising Stars list.

The state of Maryland and the federal government have filed separate lawsuits against the District of Columbia Water and Sewer Authority (DC Water), both alleging that the agency’s failure to address longstanding deterioration in the Potomac Interceptor contributed to a weeklong release of more than 240 million gallons of raw sewage into the Potomac River this past January.

Every High-Tech Building Has Many Lifespans

August 16, 2026 — Aarni Heiskanen - AEC Business
When I worked as an architect, our team designed a laboratory for fuel research. The facility included a large research hall where various boilers and other devices were tested and analyzed. The setup required extensive floor channeling under the thick concrete floor. We suggested building a modular system that would allow flexibility in the future, when requirements would certainly change. They did not want that because of budget constraints. The high-tech construction trend is spreading. Data centers, semiconductor fabs, battery plants, and life science facilities share one property that sets them apart from ordinary buildings. The technology inside turns over faster than the structure around it. Server generations change every three to five years. Rack densities have risen from 10 or 20 kW to 130 kW and beyond in just a few years. A high-tech facility is really several buildings with different lifespans inside one envelope, and we keep designing them as if they were one. The failure is not that things become obsolete. It is that we never say when each layer is expected to. Read the full story...

Credibility Matters…Even in Delay Claims

September 29, 2026 — David Adelstein - Florida Construction Legal Updates
Credibility matters. Here’s another example involving a delay claim on public private partnership delivery method. The project agreement required claims to be tried by a hearing examiner. The public private partnership developer (for lack of a better term) submitted delay claims that it contended were caused by Miami-Dade County. The hearing examiner awarded the developer delay time and compensation. On appeal, the County argued that the delays awarded by the hearing examiner were concurrent critical path delays with other delays caused by the developer’s team (the developer’s contractor). This was demonstrated by the fact that in an attempt to mitigate the County delay, the contractor’s incorporated a schedule fragnet into its schedule to mitigate delay that showed the critical path was driven by events deemed caused by the contractor. This was also reported in the contractor’s monthly updates. The developer argued that its mitigation plan did not work and, thus, the schedules showed a hypothetical delay caused by the contractor when, in actuality, it was the County-caused delay that drove the critical path. The hearing officer agreed with the contractor. Read the full story...

Data Center Construction: Contractors Must Step Up

May 26, 2026 — Aarni Heiskanen - AEC Business
I attended the Datacenter Forum 2026 in Helsinki last week. Over 400 people packed the room. Walking out, I had one overriding thought: Is construction operating in a different century from the technology it is being asked to house? Is Our Industry on Par? Ciarán Forde, Senior Vice President at CTS Nordics, opened the forum with a statement that set the tone for everything that followed: data centers are no longer just a technical challenge; they are a national strategy. Before AI, Ciarán had worked in telecoms, where data centers were already complex. But now, he said flatly, everything has changed, and the industry must rethink everything. The numbers behind the claim are staggering. Current AI data center racks run at 40 to 100 kW. In three years, 800 kW per rack is on the roadmap. And the development cycle for a new chip is roughly one year, which means deployments begin aging out almost as soon as they are commissioned. Read the full story...
