What Massachusetts Contractors and Developers Can Learn from Cannistraro v. Columbia Construction

July 13, 2026 — Anthony LaPlaca & Luke Marston - The Construction Seyt
Introduction On June 26, 2026 the Massachusetts Supreme Judicial Court issued its decision in J.C. Cannistraro, LLC v. Columbia Construction Co.—a holding that sits at the intersection of Prompt Pay Act compliance and the Massachusetts Arbitration Act.[1] Most already know that the Massachusetts Prompt Pay Act (PPA) imposes strict timing and certification requirements for rejecting payment applications and proposed change orders on projects valued at $3 million or more. Most notably, the PPA requires the paying party to give the payee written notice of its approval or rejection of progress applications and proposed changes within 15 days of receipt, which notice must include a “factual and contractual basis for the rejection” and must be “certified as made in good faith.”[2] In the absence of a timely certified notice, payment is “deemed to be approved” unless the payor properly rejects payment before it comes due.[3] Reprinted courtesy of Anthony LaPlaca, Seyfarth Shaw LLP and Luke Marston, Seyfarth Shaw LLP Mr. LaPlaca may be contacted at alaplaca@seyfarth.com Mr. Marston may be contacted at lmarston@seyfarth.com Read the full story...

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.

New Survey Reveals Overwhelmingly Optimistic Results on the Use of AI in Construction

May 14, 2026 — Construction Executive
On December 5, 2025, CMiC and Dodge released a survey asking over 6,000 companies across various sectors of the construction industry their stance on artificial intelligence—whether they use it or not; whether they like it or not; whether they have or are planning to implement it or not; and so on. Considering its reputation for skepticism and reluctance when it comes to adopting new forms of technology, the construction industry pleasantly surprised CMiC and Dodge with its answers to these questions, with 87% of contractors believing AI will have a meaningful impact on construction. “The research indicates the construction industry is nearing a tipping point for AI adoption,” says Steve Jones, senior director of industry insights at Dodge Construction Network, who sat down with Construction Executive to delve further into the survey questions and answers and what the industry’s current position on them means for AI’s future role in construction.

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.

The “Pay When Paid” Clause in California Construction—Strategies as the Battle Continues

August 03, 2026 — William L. Porter - Porter Law Group
It is well known in California Construction circles that the “Pay If Paid” clause is illegal in this state. There is a great distinction, though, between this clause and a similar clause, known as a “Pay When Paid” clause. A pay if paid clause allows a contractor to tell a subcontractor that if the contractor is unpaid for the subcontractor’s work, then the contractor has no legal obligation to pay the subcontractor, ever. For a great variety of reasons, the California Supreme Court, in the case of Wm. R. Clarke Corp v. Safeco Ins. Co. of America (1997) 15 Cal.4th 882, declared this type of clause illegal in California Construction. Although the pay if paid clause is illegal in California, the pay when paid clause is still perfectly legal and is found in many subcontracts that contractors issue to their subcontractors. The pay when paid clause allows a contractor to delay paying its subcontractors until the dispute between the contractor and the property owner over payment has been resolved and the contractor is paid by the property owner. Although seemingly reasonable (since it merely delays payment until the contractor is paid by the owner, thereby providing a funding source to pay subcontractors), significant problems still arise.

Insured General Contractor Prevails on Motion for Summary Judgment to Establish Builder’s Risk Coverage

July 06, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The general contractor’s motion for partial summary judgment successfully established that damage to footings in place before the policy period was covered after the collapse of a building. Big D Builders, Inc. v. Am Zurich Ins. Co., 2026 U.S. Dist. LEXIS 72012 (D. Idaho March 31, 2026). Big D was the general contractor for building a new airplane hangar by erecting a 38,000 square foot structure. Before Big D began construction, the site of the hangar did not contain any pre-existing structures or buildings. Before completion of the hangar, it collapsed and caused extensive property damage. The builder’s risk policy issued by Zurich covered certain aspects of the construction project for the policy period December 28, 2023, to December 28, 2024. Zurich accepted coverage for most of the damage but not for damage to footings and columns installed prior to the start date of the policy. Read the full story...

DOI Finalizes Long-Awaited Modernization of Type A Natural Resource Damage Assessment Regulations

August 03, 2026 — Amanda G. Halter, Ashleigh K. Myers & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
For nearly three decades, the U.S. Department of the Interior’s (DOI) simplified “Type A” Natural Resource Damage Assessment (NRDA) regulations were available more in theory than in practice, constrained by dated models, narrow geographic applicability and a $100,000 cap that rarely matched the economics of modern environmental claims. DOI has now finalized revisions to the Type A natural resource damages assessment procedures under 43 C.F.R. Part 11 for hazardous substance releases under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Clean Water Act (CWA), with the final rule published in the Federal Register on July 13, 2026 and scheduled to become effective August 12, 2026. As discussed previously, DOI has sought to modernize what it views as an “inefficient and inflexible” process and restore the Type A procedure to its intended role as a more streamlined pathway for smaller, less contentious NRD claims. The final rule adopts a $5 million default damages threshold, allows use above that amount if all parties agree, clarifies that Type A may be used in all environments and for all natural resource types, and removes legacy model appendices that had tethered the process to outdated formulas.
