KLEINFELDER INC

Kleinfelder Inc. specializes in archaeological survey, cultural resource management, and historical site preservation for federal defense and land management projects. Their core capabilities include subsurface and surface archaeological investigations, data recovery, archival planning, and compliance with the National Historic Preservation Act, particularly in support of military construction and infrastructure development. The firm delivers end-to-end cultural resource services—from initial reconnaissance and predictive modeling to excavation, artifact analysis, and interpretive documentation—ensuring adherence to Section 106 and NHPA requirements. Their technical expertise extends to GIS-based resource mapping, heritage impact assessment, and the development of research and archival plans for military installations, with a demonstrated focus on complex, high-stakes environments such as Marine Corps bases and Air Force munitions sites in the Pacific. The company maintains a strong, recurring relationship with the Department of Defense, consistently supporting construction and range modernization programs across Guam and other Pacific territories by integrating cultural resource mitigation into military engineering workflows. They also have a history of engagement with the Department of the Interior and the General Services Administration, delivering environmental consulting services that bridge cultural heritage preservation with NEPA compliance, endangered species protection, and wetland management. Kleinfelder’s primary industry focus is on Historical Sites (NAICS 712120), where they serve as a trusted provider of archaeologically informed planning for DoD infrastructure, and Environmental Consulting Services (NAICS 541620), where they support federal land management and environmental review processes. Their market positioning centers on mission-critical cultural resource compliance in sensitive operational zones. Based in San Diego, California, Kleinfelder Inc. operates as a small business under a 2L entity structure. While no formal government certifications are listed, their sustained contract performance with high-demand federal agencies underscores a proven track record in delivering technically rigorous, regulatory-compliant heritage services across the Pacific region.
