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...

Surety Liability Is Coextensive with Its Bond Principal

April 14, 2026 — David Adelstein - Florida Construction Legal Updates
A recent Miller act payment bond case, U.S. f/u/b/o Whitetail General Constructors v. Northcon, Inc., 2026 WL 46671 (D.Mont. 2026), contains a short noteworthy discussion as to a surety’s liability being coextensive with that of its bond principal. If you are bonded, or you are pursuing a bond, you need to appreciate this, which is why this is a noteworthy discussion:

A “surety’s liability on a Miller Act bond must be at least coextensive with the obligations imposed by the Act if the bond is to have its intended effect.” “Therefore, ‘the liability of a surety and its principal on a Miller Act payment bond is coextensive with the contractual liability of the principal only to the extent that it is consistent with the rights and obligations created under the Miller Act.’” In other words, “[w]here a subcontract’s terms are consistent with the Miller Act’s provisions, the surety’s liability on the Miller Act bond is coextensive with the contractual liability of its princip[al].”

“The liability of a surety under the Miller Act is controlled by federal law, rather than state contract law[.]” The court may, however, “look to state law when interpreting contractual provisions” in a Miller Act case.

“[T]he measure of recovery under the Miller Act is generally determined by the terms of the subcontract [or underlying contract].”

Northcon, supra, at *4-5 (internal citations omitted).

The AI Knows Too Much: When Employees Feed Trade Secrets into Generative AI Tools

April 14, 2026 — Kazim A. Naqvi & John V. Mysliwiec - Sheppard
Every time an employee pastes proprietary source code, a customer list, or a confidential business strategy into ChatGPT, Claude, or Google Gemini, they may be quietly dismantling the legal protections that make those secrets worth protecting. Courts and regulators are only beginning to grapple with this problem, and right now, the burden of preventing it falls squarely on employers. The Legal Stakes Under the federal Defend Trade Secrets Act (“DTSA”) and the Uniform Trade Secrets Act (“UTSA”) as adopted across most states, a trade secret plaintiff must show that the information at issue was subject to reasonable measures to maintain its secrecy. Courts have historically credited measures like confidentiality agreements, physical access controls, and employee training—but those safeguards were designed for a world of thumb drives and disgruntled employees. They were not built for a world where a well-meaning engineer can, in seconds, transmit an entire corpus of proprietary data to a third-party AI platform operating under terms of service that may permit the provider to use inputs for model training.

Science-Based Standards for Wildfire Recovery: What California Policyholders Need to Know About A.B. 1642

March 03, 2026 — Geoffrey B. Fehling & Yosef Itkin - Hunton Insurance Recovery Blog
Wildfires continue to present serious risks for California property owners. Unfortunately, commercial property owners, corporate facilities, landlords, and homeowners need to overcome not only the flames themselves, but also remediating hazardous contamination against a backdrop of unpredictable and ambiguous environmental safety standards. In response to the destructive Los Angeles area fires in 2025, the California Legislature recently introduced Assembly Bill 1642 aimed at creating uniform science-based standards for evaluating, testing, and clearing wildfire-impacted properties. While A.B. 1642 is in its early stages of consideration, it could materially influence claims handling, remediation costs, risk management practices, and broader liability exposures for California policyholders.

How to Fireproof a Neighborhood

March 17, 2026 — Linda Poon - Bloomberg
As builders in fire-prone areas like California race to reimagine homes for a more fiery future, one developer is zooming out to build entire fire-resilient neighborhoods. KB Home’s developments tackle an issue that’s hard for any individual homeowner to overcome: “You can do your home perfectly, but if your neighbor didn’t, you still have a fire risk,” said Roy Wright, chief executive officer of the research nonprofit Insurance Institute for Business and Home Safety. In other words, to slow the spread of urban fires it takes a village. Read the full story...

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.

A New Vision for Safety: Construction Safety Week’s Five-Year Plan

February 17, 2026 — Adam Jelen - Construction Executive
Construction Safety Week has long been a powerful show of force—a catalyst for bringing the industry together and focusing on the critical importance of health and safety. Over the last decade, we’ve made meaningful strides: advancing best practices, transitioning from hard hats to helmets, shedding light on vital issues such as mental health, fostering a culture of care and accountability and creating partnerships and initiatives that improve jobsite safety. Building on the progress we’ve made, we’ve launched a bold five-year vision to bring everyone together with trust and respect and to drive alignment in how safety is understood, owned and engineered at every step of the project. This is an industrywide effort to further deepen the culture of care centered around respect for the skilled craft and through all aspects of a project where all team members share this responsibility, this respect, across every phase: design, planning, construction and beyond.
