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environments and for all natural resource types, and removes legacy model appendices that had tethered the process to outdated formulas.

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.

Insured Does Not Prevail on Summary Judgment Motion Invoking Ensuing Loss Provision

May 05, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The court denied the insured’s motion for summary judgment finding genuine issues of fact regarding implication of the policy’s ensuing loss provision. Stella Prop. Dev.. & Event Productions, LLC v. Auto-Owners Ins. Co., 2026 U.S. Dist. LEXIS 15854 (W.D. Pa. Jan. 28, 2026). Stella owned a cultural center that was insured under a commercial property all-risk policy issued by Auto-Owners. A windstorm with gusts of 65 miles per hour struck the Center causing damage. The Center’s inspector found extensive wind damage on nearly all facets of the roof. Further, the inspector found the existing organic shingles were in “very poor condition” and were “defective, discontinued, and no longer available.” The estimated cost of repairs to the roof was $108,010.52.

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.

GRSM Secures Complete Judgment for Defense in Years-Long Dispute Spanning Multiple Venues

June 22, 2026 — Gordon Rees Scully Mansukhani
Gordon Rees Scully Mansukhani’s Hartford, Connecticut, and Dallas offices recently secured a complete defense judgment and recovery of attorney’s fees and costs in an arbitration on behalf of a longtime client, concluding a dispute that lasted several years and traversed multiple jurisdictions. The dispute initially arose in Texas state court, and almost immediately, the claimant began pursuing the matter aggressively, a pattern that continued until the day judgment was entered in GRSM’s client’s favor. GRSM’s team mounted a strong defense, achieving an early success in compelling mandatory arbitration. Read the full story...

Construction Liens and the “Substantial Performance” Doctrine

April 08, 2026 — David Adelstein - Florida Construction Legal Updates
In a recent case dealing with a construction lien, the driving issue was whether the air conditioning contractor “substantially performed” before recording its construction lien against residential property. The importance here pertains to the substantial performance doctrine with respect to construction liens. The Third District Court of Appeal explained, with relevant citations, this doctrine as follows: Under Florida law, a contractor is entitled to a mechanic’s lien if he complies with all provisions of Chapter 713, governing construction liens, and “has substantially performed the contract.” Grant v. Wester, 679 So. 2d 1301, 1307 (Fla. 1st DCA 1996) (quotation omitted); Langley v. Knowles, 958 So. 2d 1149, 1151 (Fla. 5th DCA 2007) (“The substantial performance doctrine recognizes that a contactor who complies with all of the provisions of the contactor’s lien statute is entitled to enforce a lien if he has substantially, but not completely, performed his contractual obligations.”). Substantial performance is performance “so nearly equivalent to what was bargained for that it would be unreasonable to deny the promisee the full contract price subject to the promisor’s right to recover whatever damages may have been occasioned him by the promisee’s failure to render full performance.” Ocean Ridge Dev. Corp. v. Quality Plastering, Inc., 247 So. 2d 72, 75 (Fla. 4th DCA 1971). Read the full story...

Why Construction Tendering Needs Specialized Intelligence

March 31, 2026 — Aarni Heiskanen - AEC Business
The construction industry has never lacked data; it lacks usable intelligence at the moments that matter most. In the high-stakes phases of tendering and pre-construction, the industry still relies on manual “Control-F” searches through thousands of pages of unstructured documents. I recently spoke with Herman Smith, a civil engineer and former Chief Digital Officer at Multiconsult, who left the corporate world to solve this specific bottleneck. His startup, Volve, isn’t just another AI wrapper; it is a specialized “drill” designed to penetrate the complexity of construction documentation. The Paradox of Digitalization without a Productivity Boost For years, the AEC industry has faced a frustrating paradox: we have more digital tools than ever, yet productivity has not improved. Herman observed this from the inside, managing hundreds of unique software licenses while seeing companies struggle to adapt to new workflows. Read the full story...
