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...

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).

New Law Prompts ABC Minnesota/North Dakota to Design New Telecommunications Safety Training Program

June 29, 2026 — Grace Calengor - Construction Executive
On the first day of the year, a Minnesota law requiring installers of underground telecommunication infrastructure broadband, fiber or phone lines (when projects utilize directional drilling, and/or work is being conducted within 10 feet of existing utilities) to undergo a 40-hour certification went into effect. Originally passed in mid-2024 and proposed to go into effect in July 2025, the law’s requirements were postponed until January 2026, giving ABC Minnesota/North Dakota—in partnership with NCCER and the Minnesota Cable Communications Association—time to roll out their Safety Qualified Underground Telecommunications Installer training program, which would ensure the workforce of their contractor members were certified.

We’re Burning Tokens to Clean Up Bad PDFs

August 24, 2026 — Aarni Heiskanen - AEC Business
Last Thursday, researchers from Tampere and Aalto universities reported on preliminary results of two AI- and digitalization-related projects. One project demonstrated how AI can automate the Bill of Materials process; the other tried to quantify the impact of data-driven construction and AI. The conclusion was that AI-powered automation can dramatically increase productivity, but unevenly. However, the substantial benefits may come from better outcomes rather than project efficiency. Various standards, company-specific practices, project-specific schemas, and traditions are designed for humans to comprehend. 2D drawings and text documents as PDF files, Excel sheets, and design and planning software have the information, but not the data in ideal form for automation.

Defend Now, Allocate Later? An Unresolved Tension in Colorado Construction Law

August 16, 2026 — David McLain - Colorado Construction Litigation Blog
For decades, Colorado law has recognized an important distinction between the duty to defend and the duty to indemnify. The former ordinarily arises at the beginning of litigation; the latter generally cannot be determined until the underlying liability is known. That distinction makes intuitive sense. A defense that becomes due only after litigation concludes is not much of a defense. But Colorado’s construction anti-indemnity statute, C.R.S. § 13-21-111.5(6), raises an interesting question about how that familiar rule operates in construction disputes. The statute expressly regulates contractual obligations not only to indemnify, but also to insure and defend, and it reflects a legislative policy that construction businesses should bear financial responsibility for their own negligence. Those principles have developed along separate tracks. At some point, a Colorado appellate court may have to decide precisely how they fit together. Read the full story...

AI Adoption in Construction: A UK Practitioner’s View

April 20, 2026 — Aarni Heiskanen - AEC Business
I recently talked with Chris Brady, an AI adoption consultant based in Birmingham, UK, who has spent 18 years working in construction. Two years ago, he began integrating AI into his work with contractors and SMEs, initially as an add-on service, and it has since become his main business. Chris now runs Metrix, an AI consultancy focused on UK construction companies, alongside two other ventures: Trade Upskill, an education platform for construction professionals, and ctrldash.ai, a compliance-automation SaaS for construction SMEs, both of which are soon to launch. What struck me most in our conversation was how grounded his approach is, built on years of direct industry experience rather than arriving from outside with a technology solution looking for a problem.

April 14, 2026 — Francesco "Frio" Iorio - Engineering News-Record
Everyone knows that data centers are voracious consumers of electricity. In fact, the U.S. is currently scrambling to meet unprecedented levels of power demand not seen since the early days of electrification and the widespread adoption of air conditioning. Read the full story...
