ATERRA-SCHNABEL JOINT VENTURE

ATERRA-SCHNABEL JOINT VENTURE specializes in civil engineering services focused on dam rehabilitation, watershed planning, and environmental assessment for federal infrastructure. Their technical expertise includes the design and documentation of structural upgrades for aging water control systems, preparation of supplemental watershed plans, environmental assessments under NEPA, and physical modeling studies to evaluate hydraulic performance. They deliver comprehensive A&E services from initial condition assessments through final design deliverables, with demonstrated proficiency in geotechnical analysis, hydrologic modeling, and regulatory compliance for federal dam safety programs. Their work often involves coordinating with multiple stakeholders to reconcile engineering requirements with environmental permitting, making them a trusted partner for complex, multi-disciplinary infrastructure projects. The contractor maintains a consistent and deep relationship with the U.S. Department of Agriculture, particularly its Natural Resources Conservation Service, where they provide engineering design and environmental documentation for dam rehabilitation projects across multiple states, including Massachusetts, Ohio, and Puerto Rico. Their work for the Department of Defense includes specialized physical model studies for dam safety analysis, indicating adaptability to military infrastructure standards. The pattern suggests a long-standing, mission-critical partnership with USDA, characterized by repeat engagements on similar infrastructure types. Their primary focus is engineering services under NAICS 541330, which in practice means delivering full-cycle civil engineering solutions for water resource infrastructure—particularly embankment and concrete dams—requiring integration of structural, environmental, and hydrologic disciplines. They are positioned as a niche provider for federal dam safety programs, serving agencies with aging infrastructure portfolios that demand technically rigorous, environmentally compliant design solutions. As a joint venture structured as a 2K entity based in Ambler, Pennsylvania, ATERRA-SCHNABEL operates without federal certifications but leverages technical depth and proven performance to secure repeat work. Their geographic presence is defined by project locations rather than regional offices, with a national footprint shaped by federal infrastructure needs.
