Marsh & McLennan Companies Inc. specializes in delivering expert witness and forensic legal advisory services to federal agencies, with a focused practice in high-stakes litigation support. Their core capabilities include preparing and presenting technical testimony on complex legal matters, conducting evidentiary analysis, and providing strategic counsel to legal teams navigating regulatory and procedural challenges. The firm demonstrates deep expertise in legal methodology, witness preparation, and the application of specialized knowledge to courtroom proceedings, positioning itself as a trusted resource for agencies requiring credible, defensible expert testimony in civil and administrative proceedings. The contractor has established a consistent relationship with the Department of Justice, delivering expert witness services across multiple engagements. This recurring partnership suggests a proven ability to meet the DOJ’s rigorous standards for legal precision, evidentiary integrity, and compliance with federal litigation protocols. Their work supports investigative, prosecutorial, and adjudicative functions, indicating familiarity with DOJ’s internal procedures and the evidentiary requirements of federal courts. Primarily operating under NAICS 541199—All Other Legal Services—the firm occupies a niche within the government legal services market, focusing on non-traditional legal representation that bridges technical subject matter expertise with courtroom advocacy. This vertical specialization distinguishes them from general law firms, as they provide targeted, mission-critical support rather than broad legal counsel. Marsh & McLennan Companies Inc. is a two-tiered entity headquartered in New York, NY, with no publicly disclosed federal certifications. Their geographic presence is centered in the Northeast, with operations aligned to support federal legal infrastructure. The company’s market positioning reflects a focused, high-value service model tailored to agencies requiring specialized legal expertise beyond conventional representation.

130 College Project
Solicitation # ENV-2023-2307-EIR
The 130 College Project, managed by the City of Los Angeles, involves the removal of an existing surface parking lot to construct a five-story, 232,802 square-foot commercial development on a 2.2-acre site. The facility will include 224,597 square feet of office space, 4,095 square feet of restaurant space, and 4,110 square feet of retail use, with a maximum height of 88 feet and parking distributed across one subterranean and two above-grade levels. The project is currently under environmental review under the California Environmental Quality Act, with a Final Environmental Impact Report and a Mitigation Monitoring Program established to manage impacts related to air quality, greenhouse gas emissions, noise, vibration, and utilities. Key technical requirements include a comprehensive greenhouse gas and criteria air pollutant emissions assessment covering both construction and operation phases. The project must adhere to strict professional standards, requiring personnel performing cultural resource tasks to meet the Secretary of the Interior's Professional Qualifications Standards. Environmental assessments have identified specific needs for paleontological monitoring, the protection of nearby historic resources such as Los Angeles HCM No. 211, and compliance with tribal cultural resource protocols under Assembly Bill 52. Transportation analysis emphasizes the use of Vehicle Miles Traveled as a primary metric, with proposed mitigation including a contribution to the City's Bicycle Trust Fund and the implementation of Transportation Demand Management strategies.

Letter of Interest / Advance Notice to Industry Multidisciplinary Environmental Services RFSO
Solicitation # EW699-260375
Public Works and Government Services Canada intends to establish new Departmental Individual Standing Offers to replace expiring agreements for multidisciplinary environmental services in the Western Region. The scope of work includes environmental impact assessments, permitting, biological and archaeological studies, facility management, contaminated sites consulting, and remediation planning. These services will be divided into four distinct geographic Request for Standing Offers, covering the Prairies, a specific stream for Indigenous suppliers in the Prairies under the Procurement Strategy for Indigenous Business, the Northwest Territories, and the Nunavut Settlement Area, which is limited to firms on the Inuit Firm Registry. Notably, Amendment 01 has removed Yukon from the requirements. The procurement structure utilizes a two-tier call-up system based on a threshold of 100,000 dollars, employing rotational, selective, best-fit, or competitive methods to distribute work. The process emphasizes socio-economic benefits for Indigenous peoples through Modern Treaties and Comprehensive Land Claims Agreements and adheres to the Buy Canadian Procurement Policy. A vendor performance mechanism will be implemented to adjust call-up distributions based on offeror performance. An optional pre-tender information session is scheduled for September 22, 2026, with interested parties required to submit attendee names and questions by September 16, 2026.
