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...

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...

What Construction Attorneys Do and When Contractors Need Them

August 11, 2026 — Construction Executive
Direct Answer A construction attorney advises contractors on contracts, payment rights, mechanic's liens, payment bond claims, change orders, delay claims, OSHA matters, defect claims, terminations and dispute resolution. The work covers far more than lawsuits—much of its value comes before a dispute ever becomes formal. Construction attorneys help contractors protect payment rights, manage project risk, resolve disputes and avoid contract terms that can turn a profitable job into a financial loss. Their work covers more than lawsuits. A construction attorney may review a contract before bid day, help preserve lien rights, respond to a defective work claim, prepare for mediation or defend a contractor after a safety citation. For contractors, legal counsel is often most valuable before a dispute becomes formal. A missed notice deadline, vague scope clause, unsigned change order or broad indemnity provision can create problems long before a claim is filed. Construction attorneys help identify those risks while there is still time to negotiate, document the issue or preserve leverage.

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...

What Massachusetts Contractors and Developers Can Learn from Cannistraro v. Columbia Construction

July 13, 2026 — Anthony LaPlaca & Luke Marston - The Construction Seyt
Introduction On June 26, 2026 the Massachusetts Supreme Judicial Court issued its decision in J.C. Cannistraro, LLC v. Columbia Construction Co.—a holding that sits at the intersection of Prompt Pay Act compliance and the Massachusetts Arbitration Act.[1] Most already know that the Massachusetts Prompt Pay Act (PPA) imposes strict timing and certification requirements for rejecting payment applications and proposed change orders on projects valued at $3 million or more. Most notably, the PPA requires the paying party to give the payee written notice of its approval or rejection of progress applications and proposed changes within 15 days of receipt, which notice must include a “factual and contractual basis for the rejection” and must be “certified as made in good faith.”[2] In the absence of a timely certified notice, payment is “deemed to be approved” unless the payor properly rejects payment before it comes due.[3] Reprinted courtesy of Anthony LaPlaca, Seyfarth Shaw LLP and Luke Marston, Seyfarth Shaw LLP Mr. LaPlaca may be contacted at alaplaca@seyfarth.com Mr. Marston may be contacted at lmarston@seyfarth.com Read the full story...
