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 We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property.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.

Contract Disputes Act and Jurisdictional Requirements

March 17, 2026 — David Adelstein - Florida Construction Legal Updates
When dealing with a claim on a federal construction project, there are a couple of key background jurisdictional points. These points were briefly highlighted in the recent appeal, Mega Star Logistics Service Co. v. Department of State, CBCA 8232, 2026 WL 253738 (CBCA 2026). Here are the two points. FIRST, when it comes to jurisdiction, for a board of contract appeals “to exercise jurisdiction over a claim, the CDA [Contract Disputes Act] requires the contractor to submit a written claim to the contracting officer for a COFD [contracting officer final decision], with a subsequent appeal of the COFD or deemed denial if the CO [contracting officer] does not issue a COFD.” Thus, you need to submit a formal claim under the Contract Disputes Act to the contracting officer to get a final decision from the contracting officer (or the contracting officer waiving the final decision by not timely furnishing one).

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.

U.S. Supreme Court Decision Alters Course of $745M Louisiana Coastal Damage Judgment

June 15, 2026 — Jennifer Kretschmann & Jennifer E. Michel - Lewis Brisbois
The U.S. Supreme Court has issued a unanimous decision allowing oil and gas companies to move Louisiana coastal erosion lawsuits from state court to federal court under the federal officer removal statute. While the ruling is procedural, it carries significant implications for environmental- and energy-related risks. The case, Chevron U.S.A. Inc. v. Plaquemines Parish, Louisiana, Slip Op. 24-813 (April 17, 2026), addressed a threshold jurisdictional question but has broader significance for environmental and climate related litigation. State courts are often viewed as more favorable forums for plaintiffs asserting environmental damage claims, particularly those brought by governmental entities. The opinion issued on April 17, 2026 is the latest development in long-running Louisiana coastal litigation that began more than a decade ago. Starting in 2013, Louisiana parishes filed 42 lawsuits against oil and gas companies alleging environmental damage related to historic oil field operations. The parishes alleged that oil and gas companies violated state coastal management laws by failing to properly restore impacted areas. Chevron sought to remove the cases from state court under 28 U.S.C. § 1442(a)(1), known as federal officer removal, which provides federal jurisdiction over “any person acting under [an] officer” of the United States "for or relating to any act under color of such office." The Fifth Circuit rejected the argument and remanded the case, and others like it, to state court. Trial began in March 2025 in Point à la Hache, Louisiana. On April 4, 2025, the jury awarded a total of $745 million to compensate for land loss, contamination and abandoned equipment. On June 16, 2025, the U.S. Supreme Court agreed to review the question of whether a federal contractor can remove to federal court when sued for oil-production activities undertaken to fulfill a federal oil-refinement contract.

On Checks and Balances

March 03, 2026 — Garret Murai - California Construction Law Blog
It’s called “checks and balances” for a reason. And, generally, it works well so long as there are clear boundaries between the “co-equal” branches of government. In Associated General Contractors of California, Inc. v. Department of Industrial Relations, 108 Cal.App.5th 243 (2025), the 3rd District Court of Appeals upheld a set of regulations issued by the California Apprenticeship Council that contradicted an earlier 2015 ruling of the Court of Appeals. The Associated General Contractors of California Case At issue in the case was California’s Prevailing Wage Law which requires public works contractors to hire a certain ratio of apprentices. The purpose of the apprenticeship requirements is to maintain the pipeline of skilled tradespeople on taxpayer-funded projects. Read the full story...

Sausage-Making Often Relies on the Good Sense of the Chef Rather than the Recipe

June 23, 2026 — Garret D. Murai - California Construction Law Blog
Even for lawyers, the rules governing litigation can get complex and convoluted. Does something need to be filed? What needs to be filed? When is the deadline for filing? Simple questions with not always with straightforward answers. This was the case in R & J Sheet Metal, Inc. v. W.E. O’Neil Construction Co. of California, 111 Cal.App.5th 878 (2025), which involved sheet metal panels lost when they fell into the Port of Long Beach harbor. Read the full story...

Fatalities Edge Down: New Data Reveals a Promising Decline

April 27, 2026 — Construction Executive
Construction fatalities in the United States declined slightly in 2024, according to new data released from the U.S. Bureau of Labor Statistics. The sector recorded just over 1,000 worker deaths last year—a modest decrease from the previous year but still among the highest totals of any industry. Falls remained the leading cause of death, accounting for roughly one-third of all construction fatalities. Transportation incidents—including workers struck by vehicles or equipment—ranked second, followed by contact with objects or equipment and electrocutions.

Louisiana Enacts Important Tort Reform Legislation

May 12, 2026 — Lee M. Peacocke & Benjamin Perkins - Lewis Brisbois
The Louisiana legislature enacted tort reform legislation in 2025 to address the increasing cost of insurance in Louisiana and to provide some predictability to the Louisiana legal system. While our colleagues, Jenny Michel and Jennifer Kretschmann, have provided an excellent and comprehensive analysis of the legislation in their article entitled “Louisiana State Legislature 2025 Regular Session: Tort Reform - Acts & Vetoed Insurance Bill,” which can be found here, this article examines the anticipated impact of the tort reform legislation on personal injury trials in federal and state courts in Louisiana. The most significant reform involves the institution of a modified defense of contributory negligence, which went into effect on January 1, 2026. Since 1996, Louisiana had operated as a pure comparative fault state; the liability of each party whose fault caused damages was to be allocated among the respective parties based upon their appropriate percentage of fault, regardless of the legal theory of liability asserted against each party. Thus, a plaintiff 55 percent at fault could recover 45 percent of their damages from the liable defendants. The 2025 Tort Reform Amendments now prohibit a plaintiff in a personal injury action from recovering any damages if they are found to be 51 percent or more at fault for their damages. The 55 percent at-fault party in the example above is now prohibited from recovering any damages from any party. Importantly, this new legislation now requires the trial court to instruct the jury that if they find a plaintiff to be more than 50 percent at fault, then the plaintiff will not recover any damages.
