EPA Steps Back, Arizona Moves Forward

May 12, 2026 — Patrick J. Paul, John Habib & Sukhmani K. Singh - Snell & Wilmer
In a significant development for Arizona’s business community and environmental policymakers, the U.S. Environmental Protection Agency (EPA) has paused its planned reclassification of Maricopa County from “Moderate” to “Serious” ozone nonattainment status pursuant to the Clean Air Act’s National Ambient Air Quality Standards (NAAQS). This decision marks a shift in federal air policy — one that recognizes the unique challenges faced by regions like metro Phoenix, where environmental conditions beyond local control are often key contributors to air quality readings. The EPA’s move follows a series of meetings between EPA Administrator Lee Zeldin, Arizona elected officials, and business and civic leaders, including a recent roundtable in Phoenix convened by U.S. Senator Mark Kelly. In announcing the pause, Zeldin acknowledged the need for flexibility and fairness in the application of Clean Air Act standards, especially when emissions from other states, nations, and natural events significantly influence local air quality.

Your AEC Firm Has a Memory Problem. Here Is How to Fix It

June 01, 2026 — Aarni Heiskanen - AEC Business
AEC companies trying to operationalize AI often find they lack the data foundation on which to build. There may be an abundance of data hidden in documents, but you can’t reliably use it for AI. The lack of data quality was a key topic discussed at the AI in AEC 2026 conference. During the event, I met many experts working to solve this problem, including Pavlina Nikolova, Egnyte‘s EMEA AEC Practice Lead. The chat and her presentation highlighted the challenges and ways to overcome them. Read the full story...

Congratulations to BWB&O’s Orange County Team for Securing a Strong MSJ Result in a Residential Gas Explosion Matter!

May 14, 2026 — Dolores Montoya - Bremer Whyte Brown & O'Meara LLP
Huge Congratulations to Partner Kevin Wheeler and Associate Lindsey Wells for securing a strong result on a Motion for Summary Judgment / Summary Adjudication filed on behalf of their client, the City of Murrieta. This was a complex, multi-party matter arising from a residential gas leak and explosion, where Plaintiffs alleged the City and MFPD failed to properly respond to the incident. After multiple complaints were consolidated and extensive defense work narrowed the case, eighteen plaintiffs remained asserting five causes of action against the City, prompting a comprehensive MSJ/MSA targeting liability, causation, and damages. The Court’s ruling reflects a significant win, particularly on the immunity framework. The Court eliminated the core negligence and assumed-duty claims arising from fire protection and emergency response activities. It further disposed of the misrepresentation and public nuisance claims. At the end of the day, three plaintiffs were dismissed entirely for failure to comply with Government Claims Act requirements, further reducing the scope of the case. While the dangerous condition claim remains, it does so in a very limited posture. Read the full story...

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...

Defend Now, Allocate Later? An Unresolved Tension in Colorado Construction Law

August 16, 2026 — David McLain - Colorado Construction Litigation Blog
For decades, Colorado law has recognized an important distinction between the duty to defend and the duty to indemnify. The former ordinarily arises at the beginning of litigation; the latter generally cannot be determined until the underlying liability is known. That distinction makes intuitive sense. A defense that becomes due only after litigation concludes is not much of a defense. But Colorado’s construction anti-indemnity statute, C.R.S. § 13-21-111.5(6), raises an interesting question about how that familiar rule operates in construction disputes. The statute expressly regulates contractual obligations not only to indemnify, but also to insure and defend, and it reflects a legislative policy that construction businesses should bear financial responsibility for their own negligence. Those principles have developed along separate tracks. At some point, a Colorado appellate court may have to decide precisely how they fit together. Read the full story...

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...

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.

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...
