ACEC Research Institute Report: Real Risk of AI Isn’t Technology. It’s the Org Chart.

September 01, 2026 — ACEC Research Institute
WASHINGTON (August 19, 2026) – The ACEC Research Institute today released Leading Through AI Risk: The Enterprise Framework for Engineering Firm Leaders, a new study finding that the most significant risks artificial intelligence poses to engineering firms are organizational rather than technological, and that firms treating AI as an IT initiative are managing the wrong issue. The report, part of the Institute’s yearslong Firm of the Future initiative, combines an extensive literature review with in-depth interviews of 21 leaders drawn from engineering firms, public infrastructure owners, technology vendors, insurance and legal professionals, licensing and regulatory agencies, and AI consultants. The report groups AI risk into eight interconnected domains:

technical reliability and model risk
professional liability and standard of care risk
data governance, privacy, and intellectual property risk
organizational and workforce risk
ethical, regulatory, and reputational risk
operational and cybersecurity risk
financial and business model risk
strategic leadership and enterprise governance risk

The last serves as the integrating domain through which firms coordinate responsible AI adoption enterprise wide. The report stresses that firms do not experience these risks one at a time. Weak oversight may create legal liability. Workforce gaps may affect quality assurance. “Understanding these interactions,” the study notes, “is often more important than understanding individual risks independently.” About the ACEC Research Institute The ACEC Research Institute is the independent research arm of the American Council of Engineering Companies (ACEC). Its mission is to fund and deliver research to equip the engineering industry with actionable intelligence on the issues critical to its success. Learn more at www.acecresearchinstitute.org.

Insufficient Notice of Commencement and Construction Lien Rights

August 03, 2026 — David Adelstein - Florida Construction Legal Updates
When a party is preserving their construction lien rights, the party will look to the recorded Notice of Commencement. This is the recorded document that provides the lienor with the information for purposes of preserving construction lien rights. A Notice to Owner company will typically rely on the Notice of Commencement to serve Notices to Owners from lower tiers not in contract with the owner. However, when it comes to preparing the lien, a lienor should look beyond just the Notice of Commencement and also look to the property appraiser’s website as a backstop. In a recent case, a window company had the homeowner sign the Notice of Commencement and then filled in the information. The company naturally did this for the convenience of the homeowner that probably was unfamiliar with the Notice of Commencement process. Regardless, information in the Notice of Commencement was inaccurate. It failed to include all the real property owners. Thus, when a payment dispute arose and a construction lien was prepared, it did not identify all of the real property owners. All of the real property owners were added later during the pendency of a lien foreclosure lawsuit. The trial court denied the lien because of the defective / insufficient Notice of Commencement — the lienor assumed the risk of error by filling out the information in the Notice of Commencement. The trial court further denied the lien holding that because the work did not commence within 90 days of the Notice of Commencement, the Notice of Commencement is void. 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.

Every High-Tech Building Has Many Lifespans

August 16, 2026 — Aarni Heiskanen - AEC Business
When I worked as an architect, our team designed a laboratory for fuel research. The facility included a large research hall where various boilers and other devices were tested and analyzed. The setup required extensive floor channeling under the thick concrete floor. We suggested building a modular system that would allow flexibility in the future, when requirements would certainly change. They did not want that because of budget constraints. The high-tech construction trend is spreading. Data centers, semiconductor fabs, battery plants, and life science facilities share one property that sets them apart from ordinary buildings. The technology inside turns over faster than the structure around it. Server generations change every three to five years. Rack densities have risen from 10 or 20 kW to 130 kW and beyond in just a few years. A high-tech facility is really several buildings with different lifespans inside one envelope, and we keep designing them as if they were one. The failure is not that things become obsolete. It is that we never say when each layer is expected to. Read the full story...

The ROI of Estimating Accuracy in Preconstruction

September 15, 2026 — Aaron Kivett - Construction Executive
Precision is the foundation of profitability in construction. Even minor quantity or pricing mistakes can swing bids anywhere from 5-15%, leading to project delays, unprofitable jobs or margin erosion through change orders. And worse, these losses can damage client trust and jeopardize long-term relationships that drive repeat business and future bids. Consistently estimating accurately builds confidence, speeds up bidding and positions your company to win more profitable projects. Estimating accuracy is where profit is either protected or lost. In construction, you make your biggest financial decisions before a project ever starts. Once a bid is won, most of the project’s cost structure is locked in. If the estimate is wrong, no amount of execution can fully fix those mistakes. That makes estimating accuracy a business issue, not just an operations issue.

Insurer Cannot Raise Issues on Appeal that Were Not Presented to the Trial Court

June 15, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The Florida Court of Appeals affirmed a judgment on a collapse claim for the insured, rejecting the insurer’s arguments that were not presented to the trial court. Homeowner’s Choice Prop. & Cas. Ins, Co. v. Oakes, 2026 Fl. App. LEXIS 2086 (Fl. Ct. App. March 18, 2026). The insured’s ceiling collapsed in the secondary home on the insured’s property. The claim was reported to the insurer, but coverage was denied after its investigation. The insured sued the insurer for breach of contract. Under the Additional Coverage provisions of the policy, collapse was covered if it was “abrupt.” An abrupt collapse was not covered, however, if exclusions for “Fungi, Wet or Dry Rot” and “faulty, inadequate or defective design, specifications, workmanship, repair, construction, renovation, remodeling, materials or maintenance” applied. The collapse provisions contained no language stating that the coverage granted in the provision was also subject to all the other exclusions in the policy. Read the full story...
