Description
The North River Wastewater Resource Recovery Facility (WRRF) requires comprehensive under‑deck and marine upgrades to extend its service life and meet modern environmental standards. The scope includes structural rehabilitation of steel‑filled concrete caissons, extensive concrete and waterproof‑membrane repairs beneath the deck, replacement of aging fender and dock equipment, reconstruction of ice‑breaker structures, and installation of a new security fence and lighting. The project will be executed under a competitive sealed‑bid process, with strict environmental, safety, and prevailing‑wage compliance requirements, and must be coordinated with multiple concurrent DEP contracts.
• Caisson jacketing and encasement for 506 steel‑filled caissons across four phased locations.
• Under‑deck concrete spall, crack, steel‑bar penetration, and drainage repairs, plus major and local membrane replacement (≈ 26,600 sq ft total).
• Replacement of marine rubber fenders, dock‑edge protection, bollard repaint/re‑install, and repair of a 12‑ft precast outfall pipe.
• Demolition and installation of 12 new ice‑breaker structures to protect the facility from ice loads.
• Required environmental, health & safety (EHS) plans, DBE participation (≥ 20 % of contract value), prevailing‑wage compliance, and detailed CPM schedule submission.
