California Contractors Get a Much-Needed Break: SB 342 Softens the Harsh Consequences of Contractor License Lapses

October 20, 2026 — Heather Frisch - The Construction Seyt
Imagine completing a multimillion-dollar project, performing quality work, paying your subcontractors, and satisfying the owner, only to discover that a temporary contractor license lapse could prevent you from recovering payment for that work or pursuing claims for extra work. For decades, that was the reality under California Business and Professions Code section 7031. A contractor that allowed its license to lapse, even briefly, could face catastrophic consequences completely disconnected from the quality of its work. In some cases, a contractor that performed otherwise flawless work could be barred from recovering payment and even be ordered to disgorge compensation already received – even if the owner knew the contractor had a lapse in its licensing and allowed it to continue construction. That reality is about to change. Read the full story...

From Dark Data to Building Intelligence

July 13, 2026 — Aarni Heiskanen - AEC Business
In this episode, I talk with Mark Sorsa-Leslie, founder and CEO of Auttaa AI, whose team just won first place in Luotea’s inaugural hackathon in Helsinki for turning property maintenance from reactive firefighting into proactive forecasting with AI. Mark is a chartered surveyor with 30 years of real estate data experience, previously the founder of the UK sensor company Beringar. We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property. Mark explains how Auttaa bridges real-time building data with large language models, using what he calls an “influence graph” to surface correlations and causation across previously disconnected systems, such as linking occupancy patterns to CO2 readings to diagnose ventilation problems in minutes rather than days.

Understanding the EPA’s Latest Proposed Drinking Water Contaminant Monitoring Rule, Published in Law360

September 01, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) proposed Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) represents another step in the federal government’s ongoing effort to identify and evaluate emerging contaminants in drinking water. The proposal would require certain public water systems to monitor and report on 30 unregulated drinking water contaminants from 2028 through 2030, while generating occurrence data that could inform future regulation and affect environmental, commercial, litigation and risk assessments. In an article published by Law360, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, analyzes the scope and practical implications of UCMR 6, including the contaminants selected, the proposed monitoring requirements for public water systems, and the EPA’s continued focus on PFAS and related organofluorine compounds. The article also touches upon the potential significance of publicly available monitoring data for businesses and property stakeholders. Read the full story...

Engineering Seals Versus Contracts ‘Under Seal’ (Two Very Different Things)

May 05, 2026 — Melissa Dewey Brumback - Construction Law in North Carolina
Recently, I was asked by a reader to explain the difference between a document that is ‘sealed’ by an engineer (or architect) and one that is signed ‘under seal’. This question prompted this post, as others may also be wondering about the distinction. [Hi Ed! Thanks for your question] Professionals have ‘seals’ that show that they are registered (Engineers) or licensed (Architects). As most of you likely know, your professional seal is something that is hard won and which is used when—and only when—your plans were made by you or someone under your direct supervisory control. Your signature represents that you were in responsible control over the documents, and that they have met the required professional standard of care. (21 NC Admin Code 2-0206 (a)(11)).

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.

Breaking Ground On New California Public Works Prevailing Wage Requirements

April 27, 2026 — Heather Frisch, Christopher Bouquet & Ashley Stein - The Construction Seyt
Seyfarth Synopsis: As of January 1, 2026, AB 889 bulldozed California’s Prevailing Wage law, which impacts public works employers—including public agencies, the contractors that work for them, and private owners and developers whose projects may be subject to public works requirements. The amended law reframes the calculation of fringe benefits for individuals who work on public works project and mandates annualization of such benefits, demolishes the practice of frontloading these benefits, and requires employers to maintain inspection-ready records of compliance. This year, AB 889 significantly revised California’s prevailing wage law, codified at Labor Code section 1773.1, to clarify the state’s prevailing wage regulations and streamline enforcement. Accordingly, as of January 1, 2026, California public works employers are required to annualize employees’ fringe benefits and maintain specific documentation demonstrating statutory compliance. These new obligations impact public agencies and their contractors, as well as private owners and developers whose projects may be subject to public works requirements. Continue reading for the blueprint of how to comply with the state’s amended prevailing wage law.

It’s More Than a Feeling: Proving Construction Damages and When You Should Hire an Expert to Help Do It

July 27, 2026 — Bradley E. Sands & Katie McCracken - ConsensusDocs
When you win a bid, you might be singing that everything is going your way. Then something goes wrong. The owner hands you defective plans, sits on RFI responses or other critical information, or otherwise upends the work. The costs pile up through no fault of your own. You feel wronged, and you want to be made whole. But a feeling that you got burned is not enough. To recover, that feeling has to become something the law recognizes as damages. So, what are damages, and how do you prove them? At bottom, contract damages are the money that puts the non-breaching party (i.e., the party that doesn’t breach the contract) in the position it would have occupied had the contract been performed.
