Your AEC Firm Has a Memory Problem. Here Is How to Fix It

June 01, 2026 — Aarni Heiskanen - AEC Business
AEC companies trying to operationalize AI often find they lack the data foundation on which to build. There may be an abundance of data hidden in documents, but you can’t reliably use it for AI. The lack of data quality was a key topic discussed at the AI in AEC 2026 conference. During the event, I met many experts working to solve this problem, including Pavlina Nikolova, Egnyte‘s EMEA AEC Practice Lead. The chat and her presentation highlighted the challenges and ways to overcome them. Read the full story...

Prefatory Contract Language Cannot Be Used to Create an Ambiguity with Operative Provisions

May 12, 2026 — David Adelstein - Florida Construction Legal Updates
Contract drafting and interpretation matters. A case dealt with the potential conflict with prefatory language in an agreement compared with operative provisions in the agreement. The trial court held that the operative provisions control. I discussed this case here where the appellate court reversed based on the prefatory language. But, through a motion for rehearing, the appellate court reconsidered its position and affirmed the trial court based on the operative provisions, mainly that the prefatory language cannot be used to create an ambiguity with operative provisions. Consider this explanation in affirming the trial court:

Because the trial court correctly found that the initial language in the contract was prefatory and could not be used to create an ambiguity in the remainder of the contract, we affirm the final judgment.

Alert: Fraudulent Notice of Nonpayment Defense Applies to Payment Bond Claims

April 27, 2026 — David Adelstein - Florida Construction Legal Updates
Under Florida’s Lien Law, there’s an affirmative defense or affirmative claim known as a “fraudulent lien.” The fraudulent lien defense or claim is set out in Florida Statute s. 713.31. This defense also extends to payment bond claims, whether under a private statutory payment bond (Florida Statute s. 713.23) or a public payment bond (Florida Statute s. 255.05), as it pertains to the notice of nonpayment. A notice of nonpayment needs to be served within 90 days from final furnishing to preserve a claimant’s rights against the bond. However, there really has not been a case, until now, that discusses a “fraudulent notice of nonpayment.” In K&M Electric Supply, Inc. v. Brown Electrical Solutions, LLC, 51 Fla.L.Weekly D672a (Fla. 4th DCA 2026), a prime contractor and surety prevailed at the trial level on their fraudulent notice of nonpayment defense based on a supplier’s notice of nonpayment and action against a public payment bond (under Florida Statute s. 255.05).

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.
