PSA: Be Sure to Document (Even When Time is Short)

April 14, 2026 — Christopher G. Hill - Construction Law Musings
Written change orders are a big deal. Almost all construction contracts (at least the well drafted ones) require written contracts. Written change orders are even important enough that Virginia law requires these provisions in residential construction contracts. Why are they so important? Because they are a “mini-contract” of sorts. They set the expectations, price, time, and work to be performed; work that was not included in the original price or scope for the project. Without this in writing, there will be no record of what the parties agreed to do. Does this sound familiar? Sound like its own contract? It should. Read the full story...

Wisconsin Supreme Court Finds Coverage Under Ensuing Loss Provisions

September 29, 2026 — Tred R. Eyerly - Insurance Law Hawaii
Reversing the trial court’s grant of summary judgment to the insurer, the Wisconsin Supreme Court determined that genuine issues of material fact existed on whether ensuing losses as defined in the policy were covered. Cincinnati Ins. Co. v. Ropicky, 2026 Wisc. LEXIS 302 (Wis. July 7, 2026). The insured suffered damage during a storm on May 11, 2018, when rainwater poured into the home. The insureds gave notice to their insurer, Cincinnati. Upon inspection, Cincinnati determined that water intrusion resulted from multiple construction defects in the home. In the front of the home, water entered through a gap in the stone veneer. The inspector also concluded that the damage from rainwater was not just from the May 11, 2018, storm, but damage had occurred from prior storm events. Read the full story...

How AI Turns Construction Documents Into Procurement Intelligence

May 05, 2026 — Aarni Heiskanen - AEC Business
MEP equipment accounts for up to 40% of costs on data center or hospital projects, has lead times ranging from 20 weeks to over a year, and has historically been the most underserved area in construction software. In this episode, I speak with Victor Muchiri from BuildVision about what it actually takes to make AI useful in construction procurement, not as a pilot, but in production. We dig into why you cannot simply upload a set of construction drawings to ChatGPT and trust the output. Construction documents are complex, cross-referenced, and consequential. Without deep domain context, such as manufacturer ontologies, equipment taxonomies, and engineering expertise, AI produces plausible results, not reliable ones. BuildVision’s approach is to act as a harness around AI models, wrapping them in construction-specific knowledge so the output can be trusted for real procurement decisions. 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...

Vacant Building Negates Coverage for Broken Pipe

September 01, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The Michigan Court of Appeals found the insured was not covered for water damage because the commercial space was left vacant. Cherry Hill Recreation Center, Inc. v. Conifer Ins Co., 2026 Mich, App. LEXIS 5099 (Mich Ct. App. June 18, 2026). Alan Abbas purchased a bowling alley. Due to the onset of the COVID-19 pandemic and executive orders issued by the governor, Abbas was unable to operate the bowling center for several months. During the winter, Abbas allowed the thermostat to drop significantly, with the building expected to be around 43 degrees Fahrenheit. He later admitted the sprinkler system’s pipes were not protected against freezing. Read the full story...

What Is the Independent Tort Doctrine? New Case Explains…

August 24, 2026 — David Adelstein - Florida Construction Legal Updates
Florida’s Sixth District Court of Appeals in Atout v. HHM Land Trust Dated October 29, 2013, 51 Fla.L.Weekly D1569a (Fla. 6th DCA 2026) recently included an extensive discussion on Florida’s independent tort doctrine. The independent tort doctrine is an important legal doctrine, particularly when parties are in contractual privity. This doctrine stands for the proposition that tort claims must be independent of any breach of contract. See Atout, supra. The Sixth District’s extensive discussion analyzed the indicators to determine this “independence,” which may arise from the source of the duty, the asserted conduct, the damages sought, or even public policy: Unlike claims that rely on contractual relationships, an “independent” tort is often characterized by a duty imposed by law rather than by agreement. As to this consideration, United States District Court Judge Steven Merryday has explained that the independent tort doctrine honors the same divide as the economic loss rule, but rather than looking at the nature of the loss, it focuses on the source of the duty allegedly breached. “If a contract imposes a duty, and the defendant breaches that duty, the plaintiff must sue for breach of contract. If society imposes the duty, the plaintiff must sue in tort.” Following this reasoning, courts should consider whether the alleged breach of a duty in tort coincides or overlaps with a duty imposed by a contract. If the duty at issue is within the scope of a contract, and the relationship of the parties that led to the creation of that duty stems from a contract, then that duty’s source is from contract and any alleged tort claims based on a breach of those duties may not be “independent.” Read the full story...

Seventh Circuit, With an Assist From the Illinois Supreme Court, Finds That “Pollution Exclusion” Bars Coverage For Emissions Allowed Under Regulatory Permit

April 20, 2026 — Jason Taylor - Traub Lieberman Insurance Law Blog
In Griffith Foods Int’l Inc. v. National Union Fire Ins. Co. of Pittsburgh, PA, 24-1217 & 24-1223 (7th Cir. Mar. 13, 2026), the Seventh Circuit addressed the meaning and scope of a pollution exclusion in a standard-form commercial general liability insurance policy for underlying injuries caused by ethylene oxide (EtO) emissions. The insurance dispute arose out of underlying tort litigation involving bodily injury claims, including cancer, allegedly caused by emissions of ethylene oxide over a 35-year period from 1984 through 2019 by Griffith Foods International and later Sterigenics U.S. The pollution exclusion at issue generally barred coverage for “bodily injury” arising out of the discharge, dispersal, release or escape of smoke, vapors, soot, fumes, acids, alkalis, toxic chemicals, or other irritants, contaminants or pollutants. Interpreting similar exclusions, the Illinois Supreme Court has previously held that the standard CGL pollution exclusion bars coverage for bodily injuries caused by traditional environmental pollution (essentially industrial emissions of pollutants), but not by more commonplace emissions (such as carbon monoxide from a residential furnace or excess chlorine in a backyard swimming pool). See American States Insurance Co. v. Koloms, 177 Ill. 2d 473 (Ill. 1997). In Griffith Foods, the District Court initially concluded that the pollution exclusion did not apply because the companies emitted EtO pursuant to a permit issued by the IEPA. The District Court reached this latter conclusion by applying Erie Insurance Exchange v. Imperial Marble Corp., 957 N.E.2d 1214 (Ill. App. Ct. 2011), an Illinois intermediate appellate court decision finding it ambiguous whether a CGL policy’s pollution exclusion barred coverage for emissions authorized by regulatory permit.

Federal Court Strikes Down New York’s Climate Superfund Act: What It Means for the “Polluter Pays” Movement

September 28, 2026 — Amanda G. Halter, Ashleigh K. Myers & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
A federal judge in the Northern District of New York has struck down New York’s Climate Change Superfund Act, ruling that the “polluter pays” climate law is preempted by federal law and “simply beyond the limits of state law.” The court concluded that the Clean Air Act (CAA) does not authorize New York’s compensation scheme, which calculates liability based on greenhouse gas (GHG) emissions attributable to worldwide fossil fuel extraction and refining. It separately held that any cost-recovery demand against a foreign producer would be preempted under the constitutional foreign affairs doctrine, which limits state intrusion into matters committed predominantly to the federal government. The court directed the parties to file a status report by September 14, leaving the form of further relief unresolved. In practical terms, the court has decided that the Act is preempted and cannot be enforced but has not yet determined the precise terms of its final order, including whether to formally enjoin its enforcement. The decision in West Virginia v. James, Case No. 1:25-cv-00168 (N.D.N.Y. Aug. 31, 2026), issued by Chief U.S. District Judge Brenda K. Sannes, who was appointed by President Obama, marks the first judicial invalidation of a state climate superfund statute and carries significant implications for the climate superfund landscape and the three remaining lawsuits challenging these laws.
