Inaccurate Representations Can Lead to Differing Site Conditions Claim

May 26, 2026 — David Adelstein - Florida Construction Legal Updates
In the prior posting, I discussed a case dealing with a differing site condition. In that case, the owner did not have an affirmative duty to make a representation and there was no inaccurate representation made by the owner that misled the contractor. Well, what about when there is an inaccurate misrepresentation regarding the site? This was the circumstance in an older Florida case where a dredging contractor had a successful differing site conditions claim. See Jacksonville Port Authority v. Parkhill-Goodloe, Co., Inc., 362 So.2d 1009 (Fla. 1st DCA 1978). The government provided inaccurate information as to the lack of rock that would be encountered during the dredging that was relied on by the dredging contractor. But the government had “superior knowledge” that there was rock in an adjacent location based on a prior claim from a contractor, yet the government did not disclose the possibility that rock could be encountered.

For Urban Walkers, a Patchy Dilemma: Who Owns the Sidewalk?

July 06, 2026 — Linda Poon – Bloomberg
In 2007, New York City’s sanitation department threatened Natalie Shea with a $300 fine for defacing public property with graffiti. Her crime: drawing a blue flower in front of her family’s Park Slope home with sidewalk chalk. She was six years old. The incident, which made local and national news at the time, captures the fraught role that sidewalks often play in US cities. These patches of pavement do more than carry pedestrians to their destinations: They’re also places for commerce, social interaction and childhood play, from chalking to learning how to ride a bike. Urbanist Jane Jacobs once likened the range of activities that city sidewalks attract to an “intricate ballet.” In the new book Sidewalk Nation: The Life and Law of America’s Most Overlooked Resource (Harvard University Press), author Michael Pollack explores the “tangled web of state and local regulation” that governs sidewalks, with cities often passing along responsibilities for tasks like clearing snow and keeping walkways safe. He paints a portrait of the American sidewalk a disorderly and often neglected network, filled with literal and metaphorical cracks that give rise to all sorts of conflict, from mundane clashes over maintenance to more consequential fights over accessibility and inequality.

Surety Liability Is Coextensive with Its Bond Principal

April 14, 2026 — David Adelstein - Florida Construction Legal Updates
A recent Miller act payment bond case, U.S. f/u/b/o Whitetail General Constructors v. Northcon, Inc., 2026 WL 46671 (D.Mont. 2026), contains a short noteworthy discussion as to a surety’s liability being coextensive with that of its bond principal. If you are bonded, or you are pursuing a bond, you need to appreciate this, which is why this is a noteworthy discussion:

A “surety’s liability on a Miller Act bond must be at least coextensive with the obligations imposed by the Act if the bond is to have its intended effect.” “Therefore, ‘the liability of a surety and its principal on a Miller Act payment bond is coextensive with the contractual liability of the principal only to the extent that it is consistent with the rights and obligations created under the Miller Act.’” In other words, “[w]here a subcontract’s terms are consistent with the Miller Act’s provisions, the surety’s liability on the Miller Act bond is coextensive with the contractual liability of its princip[al].”

“The liability of a surety under the Miller Act is controlled by federal law, rather than state contract law[.]” The court may, however, “look to state law when interpreting contractual provisions” in a Miller Act case.

“[T]he measure of recovery under the Miller Act is generally determined by the terms of the subcontract [or underlying contract].”

Northcon, supra, at *4-5 (internal citations omitted).

Can Anything Supersede Excel in AEC?

April 27, 2026 — Aarni Heiskanen - AEC Business
If there’s one piece of software that dominates the business world across industries, it’s Microsoft Excel. Can AI finally dethrone the mighty spreadsheet? Memorable Spreadsheet Moments Everyone has memorable spreadsheet moments. I have a few. For example, my then-architecture firm was involved in more than a dozen housing developments abroad. I developed an Excel workbook that took the required number of households as input and automatically generated a breakdown of buildings and their apartment types for AutoCAD. This was urban planning and architectural design done with a spreadsheet. I also developed business software using Excel for project portfolio management. The prototype was later scaled into a commercial SaaS that is now used globally. Another memorable moment was when a property owner told me their Excel file grew so large that it ran out of rows and columns. That must have been before 2007, when the maximum number of columns on a sheet was still just 256 and the maximum number of rows was 65,536. The current limits are 1,048,576 rows and 16,384 columns, which I hope no one will exceed. Read the full story...

Risks of Using an AI Chatbot for Legal Advice: Lessons from United States v. Heppner

April 08, 2026 — Payne & Fears LLP
Imagine that you are an executive (who is not a lawyer) and are concerned about what your company plans to do is legal. You could call your lawyer who might bill you for the call. Or, you can ask your AI chatbot, such as Claude or ChatGPT, about the legal risk. The chatbot will likely compliment you on the incisive question, provide you with highly confident answer (that may or may not be right) and will not bill you on an hourly basis. That is essentially what financial services executive Bradley Heppner did. It did not end well. A federal court recently ruled that Heppner’s chats with the AI tool Claude were not protected by attorney-client privilege or the work-product doctrine. That means that the other side (in this case, the federal government) could get access to his chatbot prompts, uploads and responses, and learn a great deal about, for example, whether Heppner knew what he was doing was illegal.

U.S. Supreme Court Decision May Negate State Law Requirement to File a Certificate of Merit with the Complaint in a Federal Action Against a Design Professional

April 27, 2026 — Christopher Olsen & Phillip Boldt - ConsensusDocs
To deter frivolous and unfounded claims against design professionals, states throughout the country have enacted statutes which generally require litigants to furnish a formal certification of merit (“COM”) from a qualified expert or face potential dismissal of their lawsuit. These COM statutes can impose a significant front-end burden on claimants who must pay an expert to review project records, interview the project team, and prepare a formal report before the lawsuit can be filed—often regardless of the amount in controversy. However, in light of a recent U.S. Supreme Court decision in a medical malpractice case, most, if not all of these statutes, may no longer be enforceable in federal court. This article examines the recent decision in Berk v. Choy, 146 S. Ct. 546 (2026), the decisions thus far which have applied Berk to invalidate COM statutes, and other categories of statutes applicable to the construction industry which may face a similar fate. The U.S. Supreme Court Decision (Berk v. Choy) In Berk, the plaintiff, Harold Berk, sued a doctor for medical malpractice under Delaware law in Delaware federal court. 146 S. Ct. at 551. Under Del. Code, Tit. 18, § 6853(a)(1), an affidavit of merit (like a COM) must accompany a complaint alleging medical malpractice. Id. Berk failed to include an affidavit of merit with his complaint. Id. at 552. Applying Delaware state law, the federal court dismissed Berk’s medical malpractice claim. Berk appealed to the Third Circuit, arguing that the affidavit of merit required by § 6853(a)(1) is unenforceable in federal court because it is more onerous than the Federal Rules of Civil Procedure. The Third Circuit affirmed the District Court’s ruling, finding § 6853(a)(1) enforceable in federal court.
