The following is a general description of the Scopes of Service included in this RFQ. The selected firms will use HEC-HMS, HEC-RAS, and/or a hydraulic grade line closed system computer model, or an approved alternative (SWMM) 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. Task orders may include any of the following:
- Surveying, utility locating, and PACP stormwater asset inspections.
- Existing and Proposed Conditions Analyses

- Public Engagement
- Preliminary and final design
- Permitting/Encroachments
(404/401, NCDOT, Railroad Agencies and FEMA Floodplain Development Permitting)
- Preparation of Construction Documents (Plans, Specifications, and Cost Estimates)
- Bid and Construction Phase Services
- Geotechnical and Structural Engineering Services
The city anticipates selecting multiple firms to provide these services. These will be drainage area-based storm drainage improvement projects that involve differing land uses within the project areas. Drainage basins may include closed and open systems. The study areas may be on a portion of the watershed or the entire watershed. Task orders may be issued for multiple projects at once. Upon satisfactorily completing a task order, the City may issue additional task orders. Scoping on these projects is anticipated to begin in early 2026.
The goal of this project is to design a booster pump station along Statesville Road. The booster pump station will have a capacity of roughly 25 MGD. The purpose will be to pump into the 978 zone, providing additional capacity. The selected firm will handle design services, permitting, and construction admin services.
This project provides design services to Charlotte Water. The project involves rehabilitation of Preliminary and Primary Treatment Facilities. Facilities generally include headworks, flow equalization basins, primary clarifiers, and gravity thickeners. A facilities evaluation, conducted by the design team, will determine the final scope of work.
This will be a request for qualification for Design Services. The project scope includes; new clarifier, new thickener, filter replacement, electric and piping upgrades, etc. Anticipated 16 month design with 20 month construction.
This opportunity has been cancelled as of 7/24
