Body
Staff Resource(s):
Carl Wilson, Charlotte Water
Explanation
§ The Doby Creek gravity sewer serves residences, businesses, and schools along the I-85 corridor between West Sugar Creek Road and the Mallard Creek Greenway in northeast Charlotte.
§ The area serviced by this gravity sewer line has seen a high rate of infill development and changes in land use related to the redevelopment along the Blue Line Extension.
§ The gravity sewer is approximately 45 years old and cannot accommodate projected growth within the service area.
§ In order to address capacity concerns, the project includes the replacement of almost three miles of 10, 12, and 15-inch diameter gravity sewer.
§ The contract with Hazen and Sawyer will be for performing preliminary design services, developing construction documents, preparing easement plats, submitting permitting packages, and providing bid phase services for the replacement of the Doby Creek gravity sewer.
§ Once the engineering design services are complete for the project, staff will bring forth a contract to the City Council in summer 2018 for construction administration services.
§ On August 3, 2016, the City issued a Request for Qualifications (RFQ) for Professional Engineering Services for Miscellaneous Sanitary Sewer Improvement Projects. In response to the RFQ, the City received 16 proposals from interested professional service providers for the five projects listed in the RFQ. The Doby Creek Sanitary Sewer Improvements was one of the five projects listed in the RFQ.
§ Charlotte Water staff evaluated the proposals and determined that Hazen and Sawyer is the best qualified firm to meet the City’s needs on the basis of demonstrated competence and qualification of professional services in response to the RFQ requirements.
§ The contract will be funded by Charlotte Water’s existing budget.
§ Construction and construction administration for the Doby Creek Sanitary Sewer Replacement project will be included in the forthcoming Charlotte Water Fiscal Years 2018-2022 Community Investment Plan.
§ This phase of the project is anticipated to be completed by the end of 2018.
