Scope of Products Requiring Proposition 65 Warnings in California Poised to Grow

February 23, 2026 — Brian M. Ledger & Chassen B. Palmer - Gordon Rees Scully Mansukhani
The scope of products to be drawn into the warning requirements under California’s Proposition 65 law may soon be growing. California’s Office of Environmental Health Hazard Assessment (OEHHA) requested information from the public on the reproductive toxicity of p,p’-bisphenol chemicals. OEHHA is the lead agency for the implementation of Proposition 65, formerly known as the Safe Drinking Water and Toxicity Enforcement Act of 1986. OEHHA’s request for information is a step toward regulators classifying all p,p’-bisphenol chemicals as reproductive toxicants under Proposition 65. California’s Proposition 65 Under Proposition 65, businesses are required to post clear and reasonable warnings before individuals are exposed to chemicals listed by the state of California as carcinogens or reproductive toxicants. To date, California has listed approximately 900 chemicals that fall under Proposition 65 regulation. Businesses may be held liable for up to $2,500 per violation per day. Proposition 65 can be enforced by public prosecutors (e.g., the California attorney general or district attorneys) or by private enforcers (known as “bounty hunters”). Reprinted courtesy of Brian M.

Endra Rethinks MEP Design with AI

July 06, 2026 — Aarni Heiskanen - AEC Business
Niklas Lindgren, co-founder and CEO of Endra, joins the AEC Business Podcast to discuss why his Stockholm-based startup is rebuilding MEP design from the ground up with AI. Endra recently raised $50 million in Series A funding and counts some of the world’s largest engineering consultancies as customers. Niklas explains why Revit’s underlying data model is too coarse to support deep automation, and why Endra built its own granular 3D data model instead of working as a plugin. He describes Endra’s “spatial AI” approach to routing conduit and ductwork without clashes, and how the platform models entire electrical systems, from receptacle to transformer, inside a single source of truth.

The Single Source of Truth in Construction Projects: Reality or Myth?

March 24, 2026 — Aarni Heiskanen - AEC Business
The idea of a single source of truth has been a fundamental part of the digital vision in the AEC industry for many years. From centralized CAD storage to BIM collaboration platforms and, more recently, Common Data Environments, the goal stays the same. Project teams want a reliable place where everyone can access the latest information. The phrase “single source of truth” comes from database and information management practices in the IT world, where the goal was to maintain one authoritative record of data and eliminate data redundancy. As the AEC industry began adopting digital tools, the same idea was applied to project information and workflows. Despite decades of technological progress, the question remains whether “one ring that rules them all” can actually be implemented in real construction projects. Read the full story...

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.

Construction Liens and the “Substantial Performance” Doctrine

April 08, 2026 — David Adelstein - Florida Construction Legal Updates
In a recent case dealing with a construction lien, the driving issue was whether the air conditioning contractor “substantially performed” before recording its construction lien against residential property. The importance here pertains to the substantial performance doctrine with respect to construction liens. The Third District Court of Appeal explained, with relevant citations, this doctrine as follows: Under Florida law, a contractor is entitled to a mechanic’s lien if he complies with all provisions of Chapter 713, governing construction liens, and “has substantially performed the contract.” Grant v. Wester, 679 So. 2d 1301, 1307 (Fla. 1st DCA 1996) (quotation omitted); Langley v. Knowles, 958 So. 2d 1149, 1151 (Fla. 5th DCA 2007) (“The substantial performance doctrine recognizes that a contactor who complies with all of the provisions of the contactor’s lien statute is entitled to enforce a lien if he has substantially, but not completely, performed his contractual obligations.”). Substantial performance is performance “so nearly equivalent to what was bargained for that it would be unreasonable to deny the promisee the full contract price subject to the promisor’s right to recover whatever damages may have been occasioned him by the promisee’s failure to render full performance.” Ocean Ridge Dev. Corp. v. Quality Plastering, Inc., 247 So. 2d 72, 75 (Fla. 4th DCA 1971). Read the full story...

Supreme Court Rules Tariffs Unconstitutional: Why the Construction Industry Shouldn’t Expect Calm Just Yet

March 31, 2026 — Christopher Barnett - Construction Executive
The U.S. Supreme Court’s 6–3 decision in Learning Resources, Inc. v. Trump did what many expected: It held that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. What few anticipated was the speed of what followed: Within hours of the ruling, the administration announced replacement tariffs under Section 122 of the Trade Act of 1974, imposed a 10% global surcharge effective February 24, and signaled forthcoming Section 301 investigations against most major trading partners. For those in the construction industry hoping the Learning Resources ruling would restore market stability, the message was unambiguous. The constitutional question may be settled, but the market disruption is not. Reprinted courtesy of Christopher Barnett, Construction Executive, a publication of Associated Builders and Contractors.
