Coastal Flood Barrier Design and Construction

The contract involves the design and construction of adaptive flood protection structures tailored for urban coastal environments, with a focus on minimizing disruption to both ecological systems and local communities. Key methodologies include phased implementation techniques, overbuilt foundations to enhance structural resilience, and nonintrusive construction practices that reduce environmental footprint. The project is designed to respond to rising sea levels and increased flood risk in Charleston, South Carolina, leveraging innovative engineering solutions that prioritize long-term sustainability and community safety. This is a subcontract opportunity issued under NAICS code 237990, with a response deadline of May 28, 2026, and is managed by the Department of Defense through its W074 Endist Charleston office. The work is exclusively targeted at the Charleston area with a ZIP code of 29403, indicating a localized but strategically critical infrastructure initiative. The solicitation was posted on April 30, 2026, and is part of broader federal efforts to modernize coastal defenses in vulnerable urban zones, with all construction activities required to align with environmental and civic impact mitigation standards.
