The selected firms will use HEC-HMS, HEC-RAS, SWMM, and/or a hydraulic grade line closed system computer model, or an approved alternative method. All methods will be in accordance with the Charlotte-Mecklenburg Storm Water Design Manual. The City’s then current AutoCAD standards will be used for production of all plans and profiles.
Work will be issued via written Task Orders, which will specify the requirements of the various projects. Multiple Task Orders may be issued for each project. Multiple task orders may be issued at once. The City of Charlotte reserves the right, upon successful completion of a given Task Order, to issue subsequent Task Orders to the same or a different Company.
The below list provides a general list of the tasks required. This is not intended to be all-inclusive, nor is it guaranteed that all of the below tasks will be utilized. A more defined Scope of Work will be developed during negotiation with the selected company.
The City anticipates selecting one (1) or more firms to provide these services on a task order basis for several pond and dam rehabilitation/ stormwater control measure (SCM) projects. This will include initial feasibility studies, planning and design fir projects that are not specified at this time. Additional tasks will include evaluation and repair design of existing municipal SCM projects. These projects are anticipated to start scoping upon contract award.
The following is a general description of the Scopes of Service included in this RFQ. The selected firms will use HEC-HMS, HEC-RAS, SWMM, and/or a hydraulic grade line closed system computer model, or an approved alternative method. All methods will be in accordance with the

Charlotte Water (CLTWater) treats raw water drawn from the Catawba River Basin and distributes treated drinking water to customers within Mecklenburg County and surrounding regions. Wastewater generated from consumptive use in eastern Mecklenburg County is discharged into the Rocky River Basin via two wastewater treatment plants (WWTPs). CLTWater intends to offset some wastewater flows that are currently tributary to the Rocky River basin due to transfer constraints and limited treatment capacities.
This Progressive Design-Build (PDB) project will likely involve the construction of at least one pumping station and force main to transfer flows from east Mecklenburg county to a wastewater treatment plant within the Catawba River Basin. Gravity sewer improvements may be necessary on the receiving sewer. The PDB firm will be required to analyze options for pumping to minimize or eliminate receiving sewer improvements. The Firm will need to consider options for storage at the pumping station or elsewhere in the system to achieve this goal.
The total anticipated CIP budget for this project is approximately $45M, assuming forcemain and gravity sewer improvements will be sized without EQ storage. The budget will vary depending on storage needs. A phased approach for the mentioned improvements, considering future connections to transfer additional flows, will be necessary to align with CIP funding schedules. CLTWater intends to have the initial project phase completed and activated to offset partial flows within two years of the notice to proceed for the planning and design work.
The PDB Team will need to have all the necessary resources to complete the planning, design, permitting, easement acquisition, and construction of this project.
