Description
This opportunity concerns the design‑build and construction of Phase II of the Chattahoochee River Trail corridor, extending from FM SR 139 to Nickajack Creek in Cobb County, Georgia. The scope includes a new 120‑ft pedestrian bridge, associated boardwalks and trail surfacing, extensive sub‑surface utility engineering (SUE), geotechnical borings, hydraulic and hydrologic analyses, environmental and ESA compliance, and related permitting. The work will be performed under the direction of Cobb County with coordination from the Georgia Department of Transportation and multiple design consultants.
• Construct a 120‑ft × 16‑ft steel pedestrian bridge and 12‑ft concrete trail, including deck, abutments, and drainage.
• Complete utility investigations (SUE), geotechnical borings, and limited bridge‑boring data to support design and construction.
• Deliver hydraulic/hydrologic modeling, flood‑plain compliance, and NPDES storm‑water mitigation plans.
• Perform environmental site assessments, mitigation planning, and obtain required easements/conservation protections.
• Provide construction‑phase services such as demolition, earthwork (≈ 2,372 cy), erosion‑control BMP installation, and post‑construction maintenance.
