Progressive Design-Build Services for Mallard Creek Interceptor Improvement Project – Phase 1 and Phase 2
Charlotte Water (CLTWater) is seeking Progressive Design-Build services to assist with the analysis, design and construction of the Mallard Creek Interceptor Improvement Project – Phase 1 and 2 (Project). Proposers need to assemble a team of experts including at a design, survey, geotechnical, environmental, permitting, pre/post blasting surveys and related seismic monitoring, real estate acquisition including appraisal and legal, and communication experts and construction contractors.
The Mallard Creek Basin service area consists mainly of residential zoning, with increasing commercial development around the new Blue Line Extension, UNC Charlotte, and the University Research Park. Infrastructure improvements are needed, not only to support current flows and maintain required service levels within the Mallard Creek Basin, but to also keep pace with the rapid growth and development. Hydraulic modelling conducted for the Mallard Creek Basin indicated that the Mallard Creek interceptor is currently capacity limited under two-year peak flow conditions. Future population and flow projections further suggested that flows in the basin would likely grow about 20 percent every 10 years. Per Charlotte Water’s Capacity Assurance Program (CAP), for the purposes of accepting new connections, adequate capacity exists when the sanitary sewer system can convey flows at a 2-year Level of Service (LOS) between the point of connection and the wastewater treatment plant without excessive surcharge, while future enhancements are sized for the 10-year peak flow condition.
Westbourne Storm Drainage Improvement Project
The project area covers approximately 20 acres and is roughly bounded by Old Plank Road to the north, Larkhaven Road to the east, Westbourne Drive to the west, and Bellhaven Boulevard to the south. The project includes storm drain improvement including culvert replacements, repair of aging and deteriorating storm drains by way of pipe system upgrades, and channel stabilization improvements. The project also includes water line upgrades and sanitary sewer relocations along with road resurfacing and seeding in affected project areas.
Elvis Storm Drainage Improvement Project
This project consists of two culverts in series under Cedarbrook Drive and Denbur Drive. Both culvert crossings consist of triple barrel corrugated metal pipe systems. This is a project that was identified by the asset management team and both culvert crossings are actively failing, and preliminary calculations show that the culverts are also undersized.
Bonwood Storm Drainage Improvement Project
|
The project involves analysis of existing conditions to determine areas suitable for improvement, planning analysis of improvement alternatives, and the design and construction of the needed improvements in the Bonwood Storm Drainage Improvement Project (SDIP) area. The Bonwood SDIP is bordered by Wendover Road to the south, Canterbury Drive to the east and Chadsford Place to the west. This project is within a drainage area of approximately 124 acres and the improvements include paving, curb and gutter, culvert replacements, pipe system lining/repair and upgrades, and minor open channel improvements. |
Chatham Storm Drainage Improvement Project
The purpose and need for this construction project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality. This project is under review. Location and project details will be provided after review is complete.
