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

This project is bordered by Old Plank Road to the north, Bellhaven Boulevard to the south, Larkhaven Road to the east and West Laporte Drive to the west. The drainage system consists of open channel and closed pipe systems underneath City maintained roads. Significant erosion and numerous sink holes have been observed. It has been identified that failing infrastructure exists underneath City maintained roads and the DM-team has made several intermediate repairs where ends of pipe systems have fallen off into the open channels. Additionally, transverse roadway overtopping has been identified at Ravenswood Road and Balfour Lane. There are existing A priority requests as far back as 2005.

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 active failing and preliminary calculations show that the culverts are also undersized.
