Wadsworth v. Regional Rail Partners — Verified Statements of Claim Under the Colorado Public Works Act

August 25, 2026 — Olivia Barden - Colorado Construction Litigation Blog
Editor’s Note: Wadsworth Revisited In August 2024, following the Colorado Court of Appeals’ decision in Ralph L. Wadsworth Construction Company, LLC v. Regional Rail Partners, we published Colorado Court of Appeals’ Ruling Highlights Dangers of Excessive Public Works Claims. At the time, the decision warranted a significant warning to contractors and subcontractors performing public work in Colorado. The Court of Appeals concluded that Wadsworth’s verified statement of claim improperly included unliquidated delay damages and that, because the claim was excessive, Wadsworth forfeited its right to recover the amounts included in the claim. We cautioned contractors to carefully scrutinize verified statements of claim and to avoid including unliquidated damages or amounts that were not yet due and payable. The Colorado Supreme Court has now reversed that decision. 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 We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property.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.

David Samani Joins BHBA Podcast on Mediation Best Practices

May 05, 2026 — Lewis Brisbois
Los Angeles Partner David Samani recently joined a Beverly Hills Bar Association (BHBA) podcast titled, “Mediation 360: Preparation from the Defense, Plaintiff, and Mediator Perspectives,” during which he shared his insights on various aspects of the mediation process. Mr. Samani, along with a plaintiff’s attorney and a mediator, presented their thoughts on topics including how to determine whether a case is appropriate for mediation, preparing to mediate a case, communicating with clients, and handling the mediation itself. Mr. Samani explained that early communication with clients is critical so that attorneys may learn what a client’s objectives are and develop an assessment of the case. He described that “from an early stage,” attorneys should determine the cost of litigation and ensure that the client understands “what an aggressive defense might entail.” As the matter progresses, attorneys and clients should “continue the dialogue” regarding costs as well as the strengths and weaknesses of the case, “making sure the client is apprised of the various alternatives that exist.” In addition, Mr. Samani discussed factors to consider when choosing a mediator, noting, “All mediators have their own styles and backgrounds.” He explained that some cases may call for a mediator with specialized knowledge in a particular area such as bankruptcy or securities, while other mediations may benefit from a mediator who understands the realities of private practice.

A Permitting Base Checklist for Data Centers and Power Plants

June 02, 2026 — Michael S. McDonough, Stephen J. Humes & Stacey C. Wright - Gravel2Gavel Construction & Real Estate Law Blog
There is a lot of talk these days about “license to operate” for data centers, meaning management of the relationships with stakeholders and broader communities concerning both the benefits and adverse consequences of locating a facility in a particular locale. Here, we are speaking of “license to operate” more literally—namely, the legal and regulatory permitting and approval requirements for a privately owned data center whether by itself or colocated with a power generating plant. Our Base Checklist includes generally and potentially applicable permitting requirements for development and operation, using California as an example. (Taking legal authority Frank Sinatra out of context, “If you can make it there, you can make it anywhere.”) The actual requirements for a given facility would depend, in part, on local law, including planning and zoning laws and plans, and the environment of the site. Just as examples, additional permitting and mitigation requirements might apply if sensitive receptors are located nearby (e.g., noise mitigation for residential dwellings), if sensitive and protected biological resources (e.g., jurisdictional waters and/or protected species) would be impacted, or if the present or former land uses require additional measures (e.g., hazardous materials remediation, mitigation for conversion of prime farmland, or protection of cultural resources). The scope of permit requirements would ultimately be determined by the applicable regulatory agencies and by the lead and responsible agencies under the applicable state environmental land use regime—in our reference case here, the California Environmental Quality Act (CEQA).
