FY23 Professional Engineering and Land Survey Services for Watermain and Sanitary Sewer Street Main Design/Extensions Contract #3 – CANCELLED

This contract is for professional services in support of the Design and Construction Division. These contracts will allow Design and Construction to assist with LCR projects which typically require a longer and more complicated design process which in turn is more costly. Examples of reasons for increased cost in LCR projects versus typical street main extensions would be the need for geotechnical investigation or wetlands investigation and permitting.

Fire Hydrants and Parts

Charlotte Water will be seeking contracts with companies for the as-needed purchase of fire hydrants and American Flow Control, Clow, Kennedy, and Mueller fire hydrant parts. One manufacturer will be selected (based on low bid) for the purchase of fire hydrants, and contracts for parts will be established for each manufacturer. Fire hydrants and parts shall be delivered to the Charlotte Water location specified at the time of purchase, with the most frequent delivery location being 5730 General Commerce Drive, Charlotte, North Carolina 28216.

Fire Extinguisher Products and Services

Charlotte Water will be issuing an RFQ  to help meet Charlotte Water’s needs with regard to fire equipment, maintenance, training, and inspection services.

Golf Village restoration service

Charlotte Water is seeking a company to provide restoration service to Golf Village’s driving range, located in South Charlotte. Charlotte Water acquired an easement diagonally across Golf Village driving range for the Steele Creek Pumping Station Replacement project.  The project included a force main, which was installed across the property in 2017. The driving range is nearly completely flat, has an uneven grade that blocks drainage, causing large puddles to form after rain. Several attempts to remedy this situation have not been successful.

A company will need specialized equipment such as laser-guided construction equipment for grading the driving range to allow for even drainage, 3-5 years experience in restoring a golf course driving range, obtaining all permits, etc.

Fiscal Year 22 Water Main Rehabilitation

This project will clean and apply a polymer coating to the interior walls of old, but still structurally sound cast iron water mains.  Also included is the replacement of all valves, hydrants, and galvanized service lines associated with each project.  The work completed in this contract will improve water quality and flow in the distribution system; consists of an undetermined number of individual projects consisting of water infrastructure rehabilitation; and/or replacements, which will be assigned by the Project Engineer.

Owners Advisor for the Clarke Creek Pumping Station and Force Main

This project will 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 to the receiving sewer.  CLTWater is proposing installation of a new Clarke Creek Pumping Station and Force Main which would involve constructing a new pumping station close to the Mecklenburg-Cabarrus County Line, in order to divert the entire Clarke Creek Basin flows to the McDowell Creek WWTP.

Progressive Design Build (PDB) is the recommended delivery model for this project. Due to critical project schedule and potential for complex multicriteria alternatives and risk analysis, Owner’s Advisor (OA) services will be needed.  In addition to decision analysis support, the selected OA scope will include scheduling and budgeting support for all phases of the project as it progresses, including monitoring design development for compliance with contract cost and schedule.

Clarke Creek Pumping Station and Forcemain Progressive Design Build Project

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.
