Engineering Seals Versus Contracts ‘Under Seal’ (Two Very Different Things)

May 05, 2026 — Melissa Dewey Brumback - Construction Law in North Carolina
Recently, I was asked by a reader to explain the difference between a document that is ‘sealed’ by an engineer (or architect) and one that is signed ‘under seal’. This question prompted this post, as others may also be wondering about the distinction. [Hi Ed! Thanks for your question] Professionals have ‘seals’ that show that they are registered (Engineers) or licensed (Architects). As most of you likely know, your professional seal is something that is hard won and which is used when—and only when—your plans were made by you or someone under your direct supervisory control. Your signature represents that you were in responsible control over the documents, and that they have met the required professional standard of care. (21 NC Admin Code 2-0206 (a)(11)).

Fatalities Edge Down: New Data Reveals a Promising Decline

April 27, 2026 — Construction Executive
Construction fatalities in the United States declined slightly in 2024, according to new data released from the U.S. Bureau of Labor Statistics. The sector recorded just over 1,000 worker deaths last year—a modest decrease from the previous year but still among the highest totals of any industry. Falls remained the leading cause of death, accounting for roughly one-third of all construction fatalities. Transportation incidents—including workers struck by vehicles or equipment—ranked second, followed by contact with objects or equipment and electrocutions.

AI in AEC 2026: Doing AI Right and Rethinking Your Business Model

April 08, 2026 — Aarni Heiskanen - AEC Business
The sixth AI at the AEC 2026 conference showcased the evolution of AI discussions. There were, naturally, many talks about software and technologies. But more than before, there were conversations about realizing AI’s business value. Two themes appeared in nearly every session I attended. First, many companies struggle with AI adoption, not because they lack tools, but because their thinking isn’t right. Second, when AI works, it disrupts the business model that brought them there.

Kahana Feld Obtains Favorable Result in High-Exposure NY Premises Liability Case

June 15, 2026 — Leigh Katz - Kahana Feld
Kahana Feld partner Leigh Katz obtained a significant victory in a recent matter involving a videotaped alleged trip and fall on the sidewalk in front of the client’s commercial residence. The plaintiff claimed he suffered a knee injury that necessitated surgery, along with other assorted injuries that prevented him from continuing high-level athletic activities. Leigh was able to demonstrate that the fall was staged and received a voluntary discontinuance with prejudice. At mediation, Leigh emphasized that KF’s expert witness challenged the plaintiff’s claim that the fall was caused by a sidewalk height differential after reviewing the videotape footage and determining the plaintiff’s fall began before his feet made contact with the alleged defect. Based on this analysis, the expert concluded the reported height differential did not initiate the fall, which supported KF’s position that the incident depicted in the video was unrealistic and appeared staged.

Massachusetts Construction Industry Continues to Wait While Prompt Payment Law Is Put to the Test

March 31, 2026 — Catherine Maronski - Construction Law Zone
Earlier this month, the Massachusetts Supreme Judicial Court (SJC) heard argument in J.C. Cannistraro, LLC v. Columbia Construction Co. et al., a dispute concerning the state’s Prompt Payment Act (PPA). Although a decision has yet to be issued, it could potentially pose widespread implications for high-value private construction projects moving forward – and perhaps backwards. The PPA, G. L. c. 149, § 29E, enacted by the Massachusetts Legislature in 2010, has become a keystone in the construction industry. It was enacted to address, in part, downstream cash flow issues that tend to pervade construction projects by mandating a series of strict guidelines for submitting, and responding to, payment applications for private projects valued over $3,000,000. Amongst these requirements are set timeframes to respond to an application, as well as what must be contained in an application rejection. Critically, if an owner or upper-tier contractor fails to fully comply with all the statutory requirements in response to a proper payment application, the application is automatically “deemed to be approved” and payable. Significantly, however, this is not always the end of the line. Read the full story...

“He Chose…Poorly: How Bad DSC Clauses Lead to Project Doom in the Last Crusade of Construction Risk”

March 10, 2026 — Curt Martin & Lee Banta - ConsensusDocs
“We do not follow maps to buried treasure, and X never, ever marks the spot.” That’s the advice that Indiana Jones offered in the Last Crusade film. But what’s beneath the surface isn’t just important to adventure archaeologists. It has real-world application to our industry, where success depends on the stability of materials below the surface. The study of geology and soils has ancient roots. Egyptians relied on soil stability for the pyramids; Rome built a continent-wide roadway system utilizing subgrade preparation techniques; Medieval builders implemented a rudimentary foundation pier system; Henri Gautier studied what is now called the “angle of repose” for French retaining walls in the early 18th Century. Through the 19th Century, contractors bore the risk of the stability of their work, and the attendant peril of unforeseen site conditions. But in the early 20th Century, design trades continued to develop increased understanding of soil and underground conditions. In the 1920’s US federal contracts began employing “differing site conditions” clauses, which provided for cost/time adjustments if subsurface conditions differed from expectations. Industry forms followed the federal policy, and these clauses became almost universally accepted. Reprinted courtesy of Curt Martin, Peckar & Abramson, P.C. and Lee Banta, Peckar & Abramson, P.C.

A Couple of Mechanic’s Lien Bills in VA [UPDATED]

February 23, 2026 — Christopher G. Hill - Construction Law Musings
Well, its that time of year again, the Virginia General Assembly is in session and looking to make changes to all kinds of things here in the Commonwealth. While most of those changes are well outside of the subject of Construction Law Musings, changes to the mechanic’s lien statutes certainly are not. This year, the Virginia General Assembly is poised to make some big changes if certain legislation gets out of committee and passes the legislature, a description and some comments on these follow: HB752 – Mechanics’ liens; liens attaching to property; memorandum of lien. [Original Description] Removes the exclusion of the attachment of a mechanic’s lien to property improved or repaired when the lien is based on a claim for repairs or existing structures. The bill further removes (i) the ability of a lien claimant to file any number of memoranda of lien including the details relating to the lien and (ii) the provisions of the Code specifying that no memorandum filed shall include sums due for (a) labor or materials furnished more than 150 days prior to the last day labor was performed or (b) material furnished to the job preceding the filing of such memorandum.
