Description
The Drowning Creek Water and Sewer Project is a municipal utility construction effort in Gwinnett County, GA, covering the installation of extensive water‑distribution and sanitary‑sewer pipelines, associated manholes, and related infrastructure. The contract will be awarded to a single, pre‑qualified contractor responsible for supplying, installing, testing, and restoring the water main (≈ 9,000 LF of ductile‑iron pipe) and sewer main (≈ 12,500 LF of ductile‑iron pipe), performing erosion‑control, traffic‑control, and roadway restoration, and de‑commissioning existing facilities. The project must be substantially complete within 520 days after contract award, with final payment due 30 days thereafter.
• Install ~9 k LF of 16‑24 in ductile‑iron water mains and ~12.5 k LF of 12‑24 in gravity sewer mains.
• Provide standard precast concrete manholes, utility‑relocation services, and full erosion‑control measures (sheet CU505, rip‑rap, geotextile, vegetation).
• Perform tunnel lining, traffic‑control, and roadway reconstruction as required, and complete the work within a 520‑day schedule.
