World's Longest Immersed Tunnel Passes Milestone, But Faces Delays

August 03, 2026 — James Leggate - Engineering News-Record
Work on the $8-billion Fehmarnbelt Tunnel, which is planned to link Germany and Denmark as the world’s longest immersed tunnel, is progressing as crews achieved a milestone last month with the successful immersion of its first precast concrete element. But Danish state-owned project owner Femern A/S says the plan is now running at least two years behind schedule and the tunnel’s road and rail portions will open in two separate stages.

For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

Communication Gaps Can Cost Construction Firms in the Data Center Boom

June 02, 2026 — Mike Lewis - Construction Executive
The data center construction boom is transforming the construction industry at a historic pace. Fueled by cloud computing, artificial intelligence and relentless demand for digital infrastructure, data centers have become one of the fastest-growing project types in the built environment. Billions of dollars are flowing into new facilities and expansions, creating unprecedented opportunities for construction firms positioned to deliver reliably. But opportunity alone does not guarantee success. As competition intensifies, communication failures and poor information management are emerging as some of the most common (and costly) reasons firms lose margins, miss deadlines or fail to secure repeat work. In data center construction, where schedules are compressed and tolerance for error is minimal, even small breakdowns in communication can have outsized consequences.

What Prevents Innovation in Construction from Taking Off

September 15, 2026 — Aarni Heiskanen - AEC Business
In construction, we have the knowledge, technology, and innovative people to radically improve our performance, yet we’re still stuck in old ways. Why is that? I attended an annual gathering for real estate and construction professionals at Rakennustieto Oy, Finland’s leading building information provider. The day before, a half-day seminar was held at the same venue. During both events, we discussed the need for change in the construction sector. Everyone agreed that we need to radically improve how we produce and share information. Read the full story...

Two Important Points Regarding the Miller Act

September 15, 2026 — David Adelstein - Florida Construction Legal Updates
A recent Miller Act case, U.S. f/u/b/o Boundless Management Outsourcing Group, LLC v. Endurance Assurance Corp, 2026 WL 2241491 (D. Puerto Rico 2026), confirms two important points when it comes to the Miller Act. In this case, a subcontractor pursued a Miller Act payment bond lawsuit more than one year after its work was finished. The subcontractor also asserted a claim against the federal government. The lawsuit was dismissed. Below are two takeaway points to consider if you are dealing with a Miller Act payment bond lawsuit. First, as it relates the claim against the federal government, the federal district court followed authority that held that the Miller Act does NOT include a waiver of sovereign immunity against the federal government. “[T]he Court does not identify any clear language in the Miller Act expressly waiving the United States or its agencies’ sovereign immunity.” Endurance Assurance Corp., supra at *3.

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.
