SERES ENGINEERING & SERVICES LLC specializes in environmental remediation and technical support services for military and federal installations, with deep expertise in vapor balance system testing, tank inspection and certification, and hazardous substance management. The firm delivers field-ready environmental engineering solutions for aboveground and underground storage tanks, including Stage 1 vapor balance assessments, leak detection, and compliance validation under EPA and DoD standards. Their technical proficiency extends to environmental consulting for corrosion control, munitions waste handling, and regulatory documentation, supporting operations at active defense sites and former military installations. A key differentiator is their hands-on execution of complex, time-sensitive field assessments requiring precision instrumentation and strict adherence to DOT, OSHA, and RCRA protocols. The contractor maintains a strong, consistent relationship with the Department of Defense, providing mission-critical environmental services across multiple bases and naval facilities. Their work supports installation compliance, environmental stewardship, and munitions lifecycle management, often underIDIQ and MATOC vehicles that require rapid response and scalable technical teams. They also deliver targeted environmental consulting to agencies requiring on-site engineering oversight for hazardous material handling and remediation planning. Primarily focused on NAICS 562910 (Remediation Services) and 541620 (Environmental Consulting Services), SERES Engineering & Services LLC positions itself as a niche provider of field-deployed environmental compliance and infrastructure integrity services. Their market focus is on defense and federal facility operations where regulatory adherence and operational continuity are paramount, particularly in munitions storage, fuel systems, and contaminated site management. As a small business structured as a 2K entity based in Charleston, SC, SERES operates without federal certifications but maintains a focused geographic footprint aligned with DoD infrastructure hubs. The company’s agility and technical specificity enable it to serve as a trusted contractor for complex, site-specific environmental tasks requiring rapid mobilization and regulatory precision.

The U.S. Army Corps of Engineers is issuing a draft program solicitation for the renovation of Hangar 750 at Pope Army Airfield, Fort Bragg, North Carolina. This project supports an Air Force Special Operations Command squadron mission and involves the comprehensive architectural and MEP build-out of ground floor aircraft maintenance bays, the integration of exterior hangar doors, and the construction of second-floor administrative and high-security operational spaces. The scope includes the installation of Level 2 wet-pipe fire suppression, intrusion detection systems, electronic access control, and full furniture, fixtures, and equipment packages. This procurement is conducted as an Other Transaction Agreement under 10 USC 2808a, meaning it is not subject to the Federal Acquisition Regulation.

The government has established an affordability cap of 35 million dollars as a material requirement, and the selected firm must be capable of providing performance and payment bonds of at least 35 million dollars. Selection is based on a qualifications-based methodology involving a two-step process: an initial evaluation of White Papers followed by Pitch Presentations for a target of three highly qualified teams. All team members must be registered in the System for Award Management with a valid Unique Entity Identifier. Additionally, the successful Design-Builder must comply with Cybersecurity Maturity Model Certification (CMMC) requirements as codified in 32 CFR Part 170, including a positive self-assessment and signed attestation of security controls. Submissions must be made through the PIEE Solicitation Module.
