Your AEC Firm Has a Memory Problem. Here Is How to Fix It

June 01, 2026 — Aarni Heiskanen - AEC Business
AEC companies trying to operationalize AI often find they lack the data foundation on which to build. There may be an abundance of data hidden in documents, but you can’t reliably use it for AI. The lack of data quality was a key topic discussed at the AI in AEC 2026 conference. During the event, I met many experts working to solve this problem, including Pavlina Nikolova, Egnyte‘s EMEA AEC Practice Lead. The chat and her presentation highlighted the challenges and ways to overcome them. Read the full story...

Managing Tariff Volatility in Cross‑Border U.S. Construction Projects: Practical Contract‑Drafting and Procurement Strategies

March 10, 2026 — Sara Beiro Farabow & Michael Wagner - The Construction Seyt
Volatile U.S. tariff announcements continue to affect international supply chains for U.S. construction projects. Although recent litigation has centered on the scope of presidential tariff authority rather than construction‑specific disputes, these decisions carry important implications for how parties structure risk in their contracts. In May 2025, the U.S. Court of International Trade (CIT) struck down certain “Liberation Day” tariffs as exceeding presidential authority under IEEPA. A federal district court in Washington, D.C. likewise issued a preliminary injunction suspending related tariffs—though it later stayed its own order pending appeal. And the Supreme Court has agreed to review cases addressing the legal limits of IEEPA‑based tariffs. While none of these developments arises from construction disputes, the themes they highlight—timing, statutory authority, and documentation—mirror the issues encountered when tariff conditions disrupt international procurement. The following strategies reflect practical steps U.S. project owners, contractors, and foreign suppliers can take to mitigate risk, drawing on drafting approaches now widely used across major construction forms, including—but not limited to—modified AIA agreements.

How Mobile Tools Are Capturing Safety Data on Jobsites

April 08, 2026 — Michael Bruns - Construction Executive
Traditionally, construction safety management is “reactive compliance”—reporting on an incident, filling out a form on paper or electronically, taking a picture and filing it away for compliance purposes. Safety management is shifting from reactive to proactive. Forward-thinking companies are using data and leading indicators to identify risks before incidents happen, not just document injuries after the fact. Mobile tools have completely changed the way safety operations work on construction sites, enabling that transition to proactive safety management.

AI Can Now Train the Soft Skills Construction Ignored

August 03, 2026 — Aarni Heiskanen - AEC Business
Most AEC professionals learn to work in teams and across teams through trial and error. There are, however, opportunities to better prepare for the real world with formal training. Until now, it has required human facilitators. Now, generative AI is emerging as a scalable alternative, which I’m also exploring. A Gap in Curricula When I studied architecture, most of the teamwork happened with co-students in the same department. However, one course focused on industrial projects where future architects and engineers collaborated on a simulated project. I’m not sure if a similar course is still in the curriculum, but it was certainly worthwhile and should have been much more extensive. Read the full story...
