Data Center Construction: Contractors Must Step Up

May 26, 2026 — Aarni Heiskanen - AEC Business
I attended the Datacenter Forum 2026 in Helsinki last week. Over 400 people packed the room. Walking out, I had one overriding thought: Is construction operating in a different century from the technology it is being asked to house? Is Our Industry on Par? Ciarán Forde, Senior Vice President at CTS Nordics, opened the forum with a statement that set the tone for everything that followed: data centers are no longer just a technical challenge; they are a national strategy. Before AI, Ciarán had worked in telecoms, where data centers were already complex. But now, he said flatly, everything has changed, and the industry must rethink everything. The numbers behind the claim are staggering. Current AI data center racks run at 40 to 100 kW. In three years, 800 kW per rack is on the roadmap. And the development cycle for a new chip is roughly one year, which means deployments begin aging out almost as soon as they are commissioned. 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 We discuss why so much building data stays dark and siloed, from outdated networking technology to the shortage of people who understand both engineering and property.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.

Key Person Provisions in Construction Contracts: Because People, Not Companies, Build Projects

October 27, 2026 — Nate Simon - Construction Executive
In construction, the person running your job matters: the project manager who sat in your preconstruction meetings, who understands the phasing, who knows why the MEP coordination sequence was set up the way it was, who has relationships with your team and the owner’s team. That person is not interchangeable. And if they disappear six weeks into the job and get replaced by someone who’s never read the drawings, you have a problem. This happens all the time. A contractor or consultant sells the A-team—the experienced project manager; the sharp superintendent; the people who won the job—during the proposal and interview. Then, once the contract is signed, those people quietly get moved to a larger project, not out of anything nefarious, but usually out of a necessity. A fire happens on another project and they are needed to put it out. By the time you realize those working on your project aren’t the ones you originally signed on, you’re three months in and the damage is already underway.

One Year In: A Look at the Initial Impacts of LEED v5 on the Built Environment

October 20, 2026 — Eric Haggstrom - Construction Executive
As federal climate policies shift, the built environment has entered a period of uncertainty where developers, designers and owners need to find pragmatic, forward-looking approaches to sustainability. A year after its launch on April 28, 2025, LEED v5 is helping lead that charge by pushing the industry toward a stronger long-term focus on carbon reduction, climate resilience and building performance. The framework of this certification provides a snapshot of the current state of the industry and an indication of where it may be headed in the future. LEED v5’s introduction has helped to begin reframing and informing the approaches of both mission-driven and cost-conscious clients, providing a framework to align their decisions more closely with sustainable priorities by emphasizing carbon reduction, energy efficiency and electrification. These standards can help teams make investments strategically by phasing in upgrades, planning for future technologies and demonstrating how the rating system is influencing long-term decision-making across projects.

Arizona Supreme Court Clarifies Parties’ Post-Default Conduct Cannot Validate Void Default Orders

August 24, 2026 — Joseph Kanefield, Ryan P. Hogan & Lilly M. Geiler - Snell & Wilmer
After filing a lawsuit, the first step is always serving process on the opposing party. While that preliminary step sounds basic enough, in McMahan v. Grasshopper, the Arizona Supreme Court recently provided a helpful refresher on the nuances of the service requirement and its importance in litigation for plaintiffs and defendants alike.1 Background McMahan arose from a hit-and-run where a tractor-trailer collided with safety barricades and injured a construction worker. The construction worker sued the tractor-trailer company, and he attempted to serve the company by leaving a copy of the complaint with the assistant to the company’s statutory agent who forwarded the complaint to the company. The assistant, however, was not authorized to accept service on the company’s behalf. Before the company appeared in the action, the construction worker successfully obtained an entry of default.

Emerging Issues in Construction CGL Insurance Part 2: The Separation of Insureds and Additional Insured Interests

September 29, 2026 — Eric M. Clarkson - SDV Fenchurch
Many coverage disputes hinge on first principles—the fundamentals of insurance —rather than the minutiae. Unfortunately, the basic anatomy of insurance policies can get lost sometimes when parties are laser-focused on a particular term or set of circumstances. This is true not just in disputes, but also when writing coverage. One of the fundamentals that is commonly misunderstood and overlooked—but which is absolutely critical to the intended operation of insurance coverage—is what is commonly known as the “separation of insureds.” The “separation of insureds” is the concept that each “insured” under a policy are referred to and treated differently, and most of all that the distinctions matter. The concept is usually included as a condition in the policy. It embodies the requirement that the policy applies to each insured distinctly from how it applies to other insureds. The ISO Form CGL policies specifically state that they apply “[s]eparately to each insured against whom a claim is made or ‘suit’ is brought.” The separate and distinct treatment of insureds is more critical in construction operations than anywhere else. This distinction is essential to ensure coverage works as intended, especially when contracted operations are involved, because the policy must insure the subcontractor that purchased the policy, the general contractor who hired the subcontractor, and the owner that hired the general contractor. Even small modifications can easily frustrate the intent of the parties. Read the full story...

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...

GRSM Trial Team Holds Alameda County Asbestos Verdict to $900,000 Against $50 Million Demand

July 27, 2026 — Gordon Rees Scully Mansukhani
Gordon Rees Scully Mansukhani Partners John Katerndahl and Vincent Gunter recently obtained an outstanding trial result for a manufacturer of asbestos-containing electrical cable, holding a jury verdict to $900,000 against a $50 million demand following an eight-week trial in Alameda County Superior Court, which is among the most challenging asbestos venues in the country. The GRSM team also included Associate Brandon Sanchez, on-site trial Paralegal Laura Vitanova, and Paralegal Kerrie Lease. The plaintiffs, the surviving spouse and four children of a former painter who died of mesothelioma, alleged that the decedent was exposed to asbestos from the company’s electrical cable during construction of a California nuclear power facility. GRSM’s client was the sole remaining defendant at trial. The plaintiffs asked the jury for $50 million and called 15 witnesses across their case-in-chief and rebuttal. Read the full story...
