Turning Expert Services into Products

July 20, 2026 — Aarni Heiskanen - AEC Business
A Finnish engineering, architecture, and project consulting company, AINS Group, recently opened an online store to purchase fixed-price services. The store presents specialist work in a product-like format, with fixed service names, defined scopes, and visible prices, such as a building history report, a zoning plan cost analysis, and a technical preliminary survey for a property transaction. Is this productization a smart move or a sign that expert services are being commoditized? Read the full story...

Construction Robotics Works Where Variation Ends

August 11, 2026 — Aarni Heiskanen - AEC Business
BuiltWorlds published its 2026 Robotics Top 50 this summer, and the list is genuinely wide. Fifty solutions across nine categories, from 3D printing and prefabricated component manufacturing to earthmoving, demolition, material transport, layout, installation, inspection, and drilling. The honorees come from sixteen countries. It looks like robotics has finally spread across the whole project lifecycle. However, having vendors in nine categories does not mean that contractors are robotizing their work en masse. Zacua Ventures, in its 2026 construction robotics report, estimates that on-site robotics accounted for less than 0.03% of global construction spending in 2025. Zacua says: “That is not a failed market. It is a market at the beginning of an adoption S-curve”, while warning that its estimates rest on private vendor data and may be high if vendors overstate how widely their machines are deployed.

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)).

Doctrine of Substantial Performance When It Comes to Payment

July 27, 2026 — David Adelstein - Florida Construction Legal Updates
A recent non-construction case touches upon the doctrine of substantial performance when it comes to payment. In this case, a club was to make two payments to secure a rapper’s attendance. The first payment was made. The second payment was made but was a few hundred dollars short of the agreed amount. The rapper did not show up. The club claimed it substantially performed its obligations. At first glance, the argument makes sense because the second payment fell only a few hundred dollars short. But that wasn’t the case when it comes to pre-commencement payment obligations:

Substantial performance applies only when the variance from the contract terms “is inadvertent or unintentional and unimportant so that the work actually performed is substantially what was called for in the contract.” However, when one party agrees to pay the other on or before a specific date, time is of the essence, and the payor is required to pay the payee on or before that date. “There is almost always no such thing as ‘substantial performance’ of payment between commercial parties when the duty is simply the general one to pay. Payment is either made in the amount and on the date due, or it is not.”

Big Gate Records, LLC v. Washington, 51 Fla.L.Weekly D1281a (Fla. 2nd DCA 2026) (internal citations omitted).

Arizona Court of Appeals Clarifies Homeowners Association Open Meeting Requirements

June 29, 2026 — Jill Casson Owen, Benjamin J. Hawkins & Stephen Wright - Snell & Wilmer
A Z N H Revocable Trust v. Sunland Springs Village Homeowners Association, No. 1 CA-CV 25-0424 (Ariz. Ct. App. Apr. 28, 2026) OVERVIEW The Arizona Court of Appeals issued an opinion clarifying how homeowners associations must conduct meetings under A.R.S. § 33-1804. The decision reinforces the legislative policy favoring transparency in association governance, bringing association meeting requirements more in line with the open meeting standards applicable to public bodies under A.R.S. § 38-431 et seq. (Arizona’s Open Meeting Law). KEY HOLDINGS 1. All Voting and Formal Actions Must Occur in Open Meetings The Court affirmed that association boards cannot vote or take formal action during closed (executive) sessions. Under A.R.S. § 33-1804(A), associations may close portions of meetings only for “consideration” of certain enumerated topics, such as legal advice, pending litigation, or personal/financial information about individual members. The Court interpreted “consideration” to mean discussion and deliberation, not voting. The Court noted that dictionaries define “consider” as “spending time thinking about a possibility” and “formulating an opinion,” which are processes that precede formal action. This interpretation mirrors how Arizona’s Open Meeting Law (A.R.S. § 38-431.03(D)) prohibits public bodies from voting in executive session.

Georgia HB 676: A Bill Property Owners and Contractors Should Watch

March 24, 2026 — Robert Lafayette - The Construction Seyt
Property owners, contractors, and others dealing with mechanics and materialmen’s liens in Georgia should keep an eye on HB 676, which is currently making its way through the Georgia General Assembly. The bill aims to curb misuse of the lien process and provide additional remedies to those challenging a frivolous lien filing. What HB 676 Would Do HB 676 would add a new Code section (O.C.G.A. § 44-14-366.6) to the mechanics and materialmen’s lien statutes. If a lien is filed “without substantial justification or that is not made in good faith or that is made with malice or a wrongful purpose,” this new Code section would impose a fine of $1,500 per lien on the lien claimant, in addition to any attorney’s fees or court costs incurred by the party challenging the lien.

The Who/What/How of Sealing Plans for Architects and Engineers (Law Note)

March 03, 2026 — Melissa Dewey Brumback - Construction Law in North Carolina
The proper use of professional seals in North Carolina is critical. Failure to follow the prescribed requirements can subject you or your Firm to a Board sanction. Did you know that the NC Board of Architecture and the NC Engineering Board have jointly prepared a fairly straightforward document that can tell you exactly what you need to know about sealing of plans? That document, the “Seal Brochure” (pdf) is available for download. Every state’s regulations are a little different (thank you Federalism!) so it is worth reviewing with your staff at regular intervals, especially if you do work across state lines.
