High-Rise Design and Construction: Then, Now, and Next

March 16, 2026 — Aarni Heiskanen - AEC Business
The Empire State Building was built in 14 months. Since 2010, the average completion time for a 200-meter-plus building has increased from 4.3 to 5.8 years. Buildings have become more complex, and there's more regulation than in the 1930s. Still, there are ways to make high-rise construction more efficient. An Unlikely Benchmark From 1930 When construction began on the Empire State Building on March 17, 1930, the world was in the midst of the Great Depression. That turned out to be an advantage. Contractors Starrett Brothers & Eken had access to a vast, motivated workforce, peaking at 3,439 workers on a single day in August 1930. Read the full story...

Construction Contract Negotiation & Drafting: A Practical Checklist (and Where State-Specific Issues Can Surprise You)

April 20, 2026 — Michelle Cooper - Sheppard Construction and Infrastructure Law Blog
Construction contract negotiation is often treated as a “forms exercise,” especially when the parties start from familiar templates (e.g., AIA forms). In practice, though, the biggest problems tend to arise not from the existence of a form, but from (i) misalignment among the project’s governing documents and participants, (ii) ambiguity in pricing and payment mechanics, and (iii) state-specific statutory requirements that override negotiated terms. This article includes a practical checklist intended to help owners, developers, and contractors streamline contract negotiations, reduce downstream disputes, and avoid unpleasant surprises during payment administration.

The Deadline to File Suit on a Public Works Payment Payment Bond is Triggered by a Claimant’s Work on a Project Not by a Claimant’s Work Under a Contract

June 02, 2026 — Garret D. Murai - California Construction Law Blog
California law requires that prime contractors furnish a payment bond – providing for payment to lower-tiered subcontractors and suppliers – on state and local public works projects with a value in excess of $25,000. There are three conditions that must be satisfied when a claimant makes a claim against a payment bond on a public works project in California:

1. First, generally, the claimant must have served a preliminary notice, unless the claimant is a first-tier subcontractor or supplier;
2. The claimant must have “ceased to provide work” on the project; and
3. The claimant must file suit against the payment bond no later than six (6) months after the period in which a stop payment notice must be given or, in other words, the earlier of 270 days after completion of the public works project or 210 days after a notice of completion or cessation was recorded on a public works project.

In Tarlton & Sons, Inc. v. Great American Insurance Company, 111 Cal.App.5th 376 (2025), the 2nd District Court of Appeal examined whether a subcontractor timely filed a claim against a payment bond when a prime contractor was terminated and replaced by another prime contractor who the subcontractor continued to perform work for.

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.

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...

Bona Fide Dispute Defeats Violation of Prompt Payment Act

June 15, 2026 — David Adelstein - Florida Construction Legal Updates
Most, if not all, jurisdictions, including the federal government, have what is known as a “Prompt Payment Act.” The objective is to ensure prompt payment. If prompt payment is not made, the Prompt Payment Act provides for interest penalties, as well as potentially other costs such as attorney’s fees. But the thing is, it’s not as simple as untimely payment to support the recourse and interest penalties the applicable Prompt Payment Act affords. And the teeth associated with the applicable Prompt Payment Act are not as sharp as perhaps the party claiming untimely payment prefers. Read the full story...

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...
