Colorado’s New Mechanic’s Lien Law: Bigger Claims, Stronger Protections, and New Risks for Owners and Contractors

October 12, 2026 — David McLain - Colorado Construction Litigation Blog
On April 6, 2026, the same day that the Colorado Supreme Court issued its decision in Ralph L. Wadsworth Construction Company, LLC v. Regional Rail Partners, Governor Jared Polis signed Senate Bill 26-074 into law. The legislation, which took effect on August 12, 2026, clarifies the amounts that may be included in mechanic’s liens and public construction payment claims, as well as the circumstances under which those claims may be considered excessive. While the timing of the Supreme Court’s decision and the Governor’s approval of SB 26-074 is noteworthy, the legislation has implications extending beyond the public works claims addressed in Wadsworth. Most significantly, it expressly addresses disputed and unliquidated amounts, including delay and disruption costs, in mechanic’s liens filed against private construction projects.

Perennial Question, Perennial Answer? EPA and Army Corps Propose Year-Round Standard for WOTUS that Could Reshape Clean Water Act Jurisdiction

October 12, 2026 — Ashleigh K. Myers & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
Federal Clean Water Act jurisdiction may be about to get considerably narrower. On September 4, 2026, the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Corps) announced a supplemental notice of proposed rulemaking that would limit federal authority over streams and wetlands to those containing water year-round—a “perennial” standard that would go beyond even what the Supreme Court required in Sackett v. EPA, 598 U.S. 651 (2023). The supplemental notice offers two options for revising the definition of “waters of the United States” (WOTUS) under the Clean Water Act (CWA): One would define “relatively permanent” waters as perennial, and the other would require perennial surface water to establish a wetland’s continuous surface connection to a jurisdictional water. If adopted, either option would substantially reduce the number of streams, wetlands and other water features subject to federal permitting, with the sharpest effects in arid and semi-arid regions where rainfall patterns leave many waterways dry for portions of the year.

Water Reuse Emerges as a Critical Strategy for Data Center Development

June 22, 2026 — Ashleigh Myers, Jillian Marullo & Jason Drogin Atwood - Gravel2Gavel Construction & Real Estate Law Blog
As demand for data centers continues to accelerate, water availability is emerging as a critical factor in project development and long-term operations. Although power supply and transmission access have historically dominated siting discussions, increasing water constraints in many regions are placing greater focus on the substantial volumes of water required to support data center cooling systems. As we covered previously, data centers are frequently located in areas already experiencing water stress and require substantial volumes of water to operate—roughly 228 billion gallons in 2023 in the United States alone—with water use projected to increase by up to 170% by 2030. Alternative cooling options, such as free-air cooling or mechanical chillers, can reduce direct water consumption but introduce their own tradeoffs. Free-air cooling is climate-dependent and often ineffective in hotter regions, while mechanical chillers increase energy demand, potentially shifting water consumption upstream through increased electricity generation.

Seattle Team Obtains Summary Judgment in Real Estate Broker Professional Liability Action

July 20, 2026 — Lewis Brisbois
Seattle Partner Kathleen A. Nelson and Associate Synova M. L. Edwards prevailed on a hotly contested motion for summary judgment in Whatcom County, Washington court in a real estate broker professional liability action. The plaintiff filed an action against Lewis Brisbois' clients, a real estate agent and brokerage firm, among several others, including the title company, purchasers and others related to the sale of real property following his complicated and long running divorce action. These claims primarily arose out of the clients’ reliance on an order signed by the court in the underlying divorce action. The order allowed the clients to execute the purchase and sale agreement, as the plaintiff was non-cooperative. 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.

Lienor Dealing With “Show Cause” Summons by Condominium Unit Owner

September 01, 2026 — David Adelstein - Florida Construction Legal Updates
One of the statutory vehicles to shorten a construction lienor’s statute of limitations to foreclose on a construction lien is through a “show cause” summons that essentially requires the lienor to foreclose on the lien within 20 days from receipt of the “show cause” summons. This is a statutory procedure under Florida’s Lien Law in Fla. Stat. s. 713.21(4). If a lienor receives a “show cause” summons and lawsuit, the lienor should, without delay, counterclaim or file a separate lien foreclosure lawsuit within the 20-day period without exception. This is provided the lienor wants to move forward with its lien. If a lienor does not, the lien will be discharged of record. If you are a lienor and receive a “show cause” summons, please immediately consult with construction counsel that can best advise you and perfect your lien rights. Read the full story...
