Research Illuminates Pollution Problem in Tijuana River Valley

June 29, 2026 — Jeff Yoders - Engineering News-Record
The Tijuana River watershed between southern California and northern Mexico has been the epicenter of an environmental and public health crisis for more than two decades. Since October 2023 alone, more than 31 billion gallons of raw sewage and polluted water have flowed into the U.S. and, eventually, the Pacific Ocean. Read the full story...

New York Construction Employers Face New Reporting and Cancellation Pay Requirements Beginning December 8, 2026

October 26, 2026 — Bradley J. Bartolomeo & Clare M. Cunningham - Lewis Brisbois
Effective December 8, 2026, pursuant to the New York Construction Reporting Pay Act, employers in the New York State construction industry will be subjected to new reporting requirements and will be required to pay both union and non-union workers for certain last-minute schedule changes, even when the disruption is caused by weather, failed inspections, material shortages, site-access restrictions, or delays attributable to owners, general contractors, or other trades. For many contractors, routine decisions that have historically been considered part of construction scheduling risk may now create mandatory wage obligations, prevailing wage compliance concerns, and potential wage-and-hour litigation exposure.

Arbitration in Construction Disputes: Process and Best Practices

July 27, 2026 — Construction Executive
Arbitration in construction disputes is a private process where owners, contractors, subcontractors, designers or suppliers present claims to one or more neutral arbitrators instead of taking the dispute through court. The arbitrator reviews evidence, hears testimony and issues a decision that is usually binding. Construction arbitration is common because project disputes are technical, document-heavy and time-sensitive. Claims may involve schedule delays, disputed change orders, defective work, differing site conditions, payment, termination, indemnity, surety issues or professional liability. Arbitration can be faster and more specialized than litigation, but speed is not guaranteed. Poor contract language, broad discovery, weak records and unclear damages can make arbitration expensive.

Your Construction Contract Won’t Always Save You From a Bad Project Record

November 02, 2026 — Matthew J. Devries - Best Practices Construction Law Blog
Construction contracts are full of protections. No-damage-for-delay clauses. Consequential damage waivers. Rights to supplement a subcontractor’s work. Broad scheduling provisions. But a recent Tennessee construction case provides an important reminder: the best contract in the world may not save you from bad project facts. In Commercial Painting Company, Inc. v. The Weitz Company, LLC (TN Ct. App. Oct. 28, 2026), the dispute involved a general contractor and its drywall subcontractor on a multi-building retirement community. The subcontract was originally worth more than $3.2 million, and the parties eventually disagreed about delays, scheduling, supplemental work, backcharges, and unpaid applications for payment. What began as a fairly typical construction dispute became anything but typical. A jury ultimately found that the general contractor had intentionally misrepresented material facts and awarded the subcontractor $3.9 million in punitive damages. (The case has a lengthy procedural history involving multiple appeals, but this post focuses only on the practical lessons from the most recent decision.) Read the full story...

The Great Escape: Non-Invalidation Clauses and Property Damage Claims

October 20, 2026 — Abigail Smith & Kaarthiga Manimaran - SDV Fenchurch
At their core, non-invalidation clauses (“NICs”) recognise an important commercial reality: an insured cannot control everything that happens at its premises. In the event that an insured finds itself in breach of a condition or warranty owing to events that have increased the risk of damage to its property, but which were outside its authority, knowledge or beyond its control, a NIC may prevent the insurer from avoiding the claim. For that reason, they’re an important tool in an insured’s coverage arsenal. Although there is relatively little caselaw on NICs, their purpose was recognised in The Seashell of Lisson Grove Ltd v Aviva Insurance Ltd [2011] EWHC 1761 (Comm) (on which we wrote a previous article – The Good, the Bad & the Ugly: #26 The Good: The Seashell of Lisson Grove Ltd v Aviva) Reprinted courtesy of Abigail Smith, SDV Fenchurch and Kaarthiga Manimaran, SDV Fenchurch Ms. Smith may be contacted at abigail.smith@sdvfenchurch.uk Ms. Manimaran may be contacted at kaarthiga.manimaran@sdvfenchurch.uk Read the full story...

We’re Burning Tokens to Clean Up Bad PDFs

August 24, 2026 — Aarni Heiskanen - AEC Business
Last Thursday, researchers from Tampere and Aalto universities reported on preliminary results of two AI- and digitalization-related projects. One project demonstrated how AI can automate the Bill of Materials process; the other tried to quantify the impact of data-driven construction and AI. The conclusion was that AI-powered automation can dramatically increase productivity, but unevenly. However, the substantial benefits may come from better outcomes rather than project efficiency. Various standards, company-specific practices, project-specific schemas, and traditions are designed for humans to comprehend. 2D drawings and text documents as PDF files, Excel sheets, and design and planning software have the information, but not the data in ideal form for automation.

Supply Chain Is a Legal Exposure—Not Just a Force Majeure Problem

September 08, 2026 — Owen Newman - Construction Executive
This is not another force majeure article. The supply-chain related legal exposure that contractors are carrying today—in sanctions risk, specification non-compliance, warranty exposure and regulatory volatility—extends well beyond what even a well-drafted force majeure clause protects. An engineering, procurement and construction contractor on a gas-fired power plant discovers during commissioning that transformer oil in a critical unit contains Russian-origin naphthenic base oil, which is a prohibited source under Office of Foreign Assets Control sanctions. The contractor didn’t source it. A subsupplier two tiers below made the substitution when disruptions in the Strait of Hormuz tightened the primary supply chain for this specialty product and no one in the purchase-order chain flagged it. The procurement decision is long done and the documentation trail that should have caught it doesn’t exist.

When Arbitrators Overreach: Utah Supreme Court Trims an Award Built on an Unpled Claim

November 02, 2026 — Tyson J. Prisbrey & Mark O. Morris - Snell & Wilmer
Construction industry participants have long favored arbitration to resolve disputes, prizing its speed, confidentiality, and finality over traditional litigation. That finality, however, depends on arbitrators staying within the bounds of what the parties actually put before them. In RV Holdings 4, LLC, et al. v. Standard Fiber Investors, LLC, the Utah Supreme Court issued a rare rebuke of an arbitration award, holding that the arbitrator exceeded their authority by awarding damages on a claim the prevailing party never submitted for decision. The dispute arose from a management-fee relationship between Standard Fiber, a bedding manufacturer, and several affiliated “Ridgeview” entities that provided financial and accounting oversight services. After Standard Fiber stopped paying management fees in 2020, the parties pursued their claims in arbitration. Ridgeview’s arbitration demand sought recovery under two specific theories: that a 2006 management services agreement remained in effect, and alternatively, that an oral “50/50 Agreement” entitled it to a share of fees paid to an affiliated entity. Notably, Ridgeview never asserted a claim for breach of a separate 2014 fee arrangement, and affirmatively disavowed reliance on it. The arbitrator rejected both of Ridgeview’s submitted theories and instead awarded Ridgeview $725,000 based on that unpled 2014 agreement. The district court confirmed the award, concluding that the arbitrator’s decision was rationally related to the parties’ arguments, including evidence Standard Fiber itself introduced about the 2014 arrangement.
