Barrington Hills Pump Station Eliminations (10230090)

The City of Cincinnati is seeking qualified contractors to eliminate five existing pump stations in the Barrington Hills area and construct a new gravity‑driven sanitary sewer system (~9,667 ft of 8‑ to 18‑inch pipe). Work includes extensive site clearing, sewer‑line abandonment, horizontal directional drilling (HDD) of a 16‑inch HDPE pipe, manhole construction, creek‑crossing restoration, de‑watering, temporary access drives, environmental compliance (SWPPP, silt‑fence, storm‑water mitigation), and related ancillary tasks such as project signage and performance‑bond provision. Bidders must submit unit‑price bids using the latest Volume 3 REV 3 sheet and comply with detailed measurement‑and‑payment percentages, DBE goals, and Build‑America/Buy‑America requirements. • Removal and salvage of five pump stations and associated underground infrastructure. • Installation of new gravity sewer using trenchless methods (HDD, jack‑and‑bore, auger bore) for multiple pipe diameters (6‑ to 18‑in.). • Comprehensive environmental mitigation (creek restoration, silt‑fence, SWPPP) and de‑watering of the site. • Full suite of civil‑construction tasks: clearing & grubbing, special excavation/fill, concrete masonry, manhole construction, temporary access roads, and final pavement restoration.
