This award‑winning Design‑Bid‑Build contract calls for the complete demolition of existing weapons magazines, construction of new underground Type H, Type G, and six CLWS magazines, and the associated Ordnance Operations Facility at Naval Submarine Base New London, Connecticut. The effort includes extensive site work, utility upgrades, storm‑water management, environmental mitigation (wetlands, ribbon‑snake, bat‑nesting restrictions), security upgrades, and compliance with Navy explosive‑safety, HERO, and blasting regulations. • Demolition of multiple legacy magazines and ancillary buildings, hazardous‑material remediation, and soil‑stabilization. • Construction of new underground magazines (Type H, Type G, six CLWS) with 5‑ton and 25‑ton overhead cranes, reinforced concrete, blast‑door systems, and advanced fire‑stop and air‑tightness testing. • Full civil, structural, mechanical, electrical, fire‑protection, and security system integration, including utility cut‑overs, storm‑water facilities, and a high‑security perimeter. • Strict environmental controls: wetland permits, tree‑clearing windows (Apr 1‑Oct 31), golf‑course utility windows (Nov 1‑Mar 30), and ribbon‑snake habitat protection. • Schedule of 1,982 calendar days with liquidated‑damage penalties per milestone, requiring rigorous project‑control and earned‑value reporting.
