Ninth Circuit Holds That Policies Covering Environmental Claims Do Not Have Aggregate Limits

May 12, 2026 — Lorelie S. Masters & Joseph T. Niczky - Hunton Insurance Recovery Blog
In the case of County of San Bernardino v. Insurance Company of the State of Pennsylvania, the Ninth Circuit recently addressed the issue of whether general liability policies issued in the 1960s and 1970s included aggregate limits for claims arising under the premises-operations coverage in CGL policies. The difference between the policyholder’s interpretation of the policies’ limits clauses and the insurer’s interpretation was worth hundreds of millions of dollars in exposure for the insurer. The Court closely examined the policy language and extrinsic evidence from both the insurance industry’s drafting history and the parties before concluding that the policies were ambiguous. The Court construed that ambiguity in favor of the policyholder and ruled that aggregate limits did not apply to the claims at issue. The Court’s decision underscores the importance of carefully examining a policy’s limits, especially for older policies written before 1986 when the insurance industry revised the standard-form CGL policy to state the aggregate limits apply not only to products liability claims but to premises-operations claims as well. Decades of insurance industry drafting history confirms, as the policyholder’s submissions in this case indicate, that the industry well understood that operations claims like the environmental waste-disposal claims at issue here typically were not subject to aggregate limits.

Doctrine of Substantial Performance When It Comes to Payment

July 27, 2026 — David Adelstein - Florida Construction Legal Updates
A recent non-construction case touches upon the doctrine of substantial performance when it comes to payment. In this case, a club was to make two payments to secure a rapper’s attendance. The first payment was made. The second payment was made but was a few hundred dollars short of the agreed amount. The rapper did not show up. The club claimed it substantially performed its obligations. At first glance, the argument makes sense because the second payment fell only a few hundred dollars short. But that wasn’t the case when it comes to pre-commencement payment obligations:

Substantial performance applies only when the variance from the contract terms “is inadvertent or unintentional and unimportant so that the work actually performed is substantially what was called for in the contract.” However, when one party agrees to pay the other on or before a specific date, time is of the essence, and the payor is required to pay the payee on or before that date. “There is almost always no such thing as ‘substantial performance’ of payment between commercial parties when the duty is simply the general one to pay. Payment is either made in the amount and on the date due, or it is not.”

Big Gate Records, LLC v. Washington, 51 Fla.L.Weekly D1281a (Fla. 2nd DCA 2026) (internal citations omitted).

Communication Gaps Can Cost Construction Firms in the Data Center Boom

June 02, 2026 — Mike Lewis - Construction Executive
The data center construction boom is transforming the construction industry at a historic pace. Fueled by cloud computing, artificial intelligence and relentless demand for digital infrastructure, data centers have become one of the fastest-growing project types in the built environment. Billions of dollars are flowing into new facilities and expansions, creating unprecedented opportunities for construction firms positioned to deliver reliably. But opportunity alone does not guarantee success. As competition intensifies, communication failures and poor information management are emerging as some of the most common (and costly) reasons firms lose margins, miss deadlines or fail to secure repeat work. In data center construction, where schedules are compressed and tolerance for error is minimal, even small breakdowns in communication can have outsized consequences.

EPA Expands PFAS Reporting Requirements with Addition of New Chemical to Toxics Release Inventory, Published by Law360

June 08, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) addition of sodium perfluorohexanesulfonate (PFHxS-Na) to the Toxics Release Inventory (TRI) introduces new federal reporting requirements for businesses that manufacture, process, or use the chemical. Because reporting obligations apply retroactively to the start of the year, affected facilities must quickly evaluate their compliance and recordkeeping practices. In a recent Law360 article, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, explains why PFHxS-Na was automatically added to the TRI, how the EPA’s public reporting system works, and which businesses may be affected by the new rule. The article also touches upon key compliance considerations, including supply chain reviews, reporting thresholds for chemicals of special concern, and preparation for public disclosure requirements.

Potential Gap in Workers Compensation Immunity Statutory Framework

June 02, 2026 — David Adelstein - Florida Construction Legal Updates
Workers compensation insurance is important. As an owner, you want to ensure the contractors you hire have workers compensation insurance. Assuming you hire a contractor that is statutorily exempt from workers compensation, you want to make sure, no exception, that any subcontractor that is hired has workers compensation insurance. (Regardless, you always want subcontractors to have workers compensation insurance.). In construction, the prime contractor serves as the “statutory employer” for purposes of workers compensation insurance. With workers compensation comes workers compensation immunity.

New Survey Reveals Overwhelmingly Optimistic Results on the Use of AI in Construction

May 14, 2026 — Construction Executive
On December 5, 2025, CMiC and Dodge released a survey asking over 6,000 companies across various sectors of the construction industry their stance on artificial intelligence—whether they use it or not; whether they like it or not; whether they have or are planning to implement it or not; and so on. Considering its reputation for skepticism and reluctance when it comes to adopting new forms of technology, the construction industry pleasantly surprised CMiC and Dodge with its answers to these questions, with 87% of contractors believing AI will have a meaningful impact on construction. “The research indicates the construction industry is nearing a tipping point for AI adoption,” says Steve Jones, senior director of industry insights at Dodge Construction Network, who sat down with Construction Executive to delve further into the survey questions and answers and what the industry’s current position on them means for AI’s future role in construction.

Can Anything Supersede Excel in AEC?

April 27, 2026 — Aarni Heiskanen - AEC Business
If there’s one piece of software that dominates the business world across industries, it’s Microsoft Excel. Can AI finally dethrone the mighty spreadsheet? Memorable Spreadsheet Moments Everyone has memorable spreadsheet moments. I have a few. For example, my then-architecture firm was involved in more than a dozen housing developments abroad. I developed an Excel workbook that took the required number of households as input and automatically generated a breakdown of buildings and their apartment types for AutoCAD. This was urban planning and architectural design done with a spreadsheet. I also developed business software using Excel for project portfolio management. The prototype was later scaled into a commercial SaaS that is now used globally. Another memorable moment was when a property owner told me their Excel file grew so large that it ran out of rows and columns. That must have been before 2007, when the maximum number of columns on a sheet was still just 256 and the maximum number of rows was 65,536. The current limits are 1,048,576 rows and 16,384 columns, which I hope no one will exceed. Read the full story...
