Coast and Harbor Associates, Inc. specializes in construction management and engineering services for federal infrastructure projects, with deep expertise in project oversight, construction inspection, and program delivery for public works. The firm provides end-to-end construction management support, including compliance monitoring, quality assurance, schedule coordination, and contract administration for federal facilities. Their technical proficiency spans FASCSA and FASCA clause implementation, multi-agency blanket purchase agreement execution, and complex CM delivery models for historic and mission-critical structures. They are particularly adept at managing construction activities in sensitive environments, including national park sites and coastal defense installations, ensuring adherence to federal standards and environmental regulations. The contractor maintains a strong, long-standing relationship with the General Services Administration, delivering construction management and project management services under multiple-award contracts and schedule vehicles. They also serve the Department of the Interior on national park infrastructure projects and support the Department of Homeland Security with security-focused construction inspection at critical coastal installations. Their work consistently involves federal facility modernization, preservation of historic structures, and compliance with federal procurement and construction codes. Their primary focus is on NAICS 541330—Engineering Services—where they deliver specialized construction oversight, technical review, and contract administration rather than design. This positions them as a trusted implementation partner for agencies requiring rigorous field-level engineering management. They operate with precision in federally regulated environments, emphasizing documentation integrity, regulatory compliance, and stakeholder coordination. As a Women-Owned Small Business and Woman-Owned Business certified firm based in Marblehead, Massachusetts, Coast and Harbor Associates leverages its small business status to deliver agile, responsive services to federal clients across the Northeast and beyond. Their certification enhances their ability to compete for set-aside opportunities while maintaining a reputation for reliability and regulatory expertise in federal construction programs.
