The mechanical demolition work consists of removing the five (5) existing split system gas furnaces and outdoor air-conditioning condensers, and the one (1) inline exhaust fan above the men’s locker room. All existing ceiling diffusers and grilles shall be demolished and replaced inplace in new work. Existing split system controls, bipolar ionization devices, furnace terminations, and ductwork are to be kept and reused in the new work. The new mechanical work consists of installing five (5) new split system heat pumps and gas furnaces in the same place as demolished split systems, and reusing controls, bipolar ionization, existing furnace intakes/vents and reconnecting to existing gas. Outside air dampers will be adjusted to reduce outside air flow. Existing controls will need to be reworked to account for the change from cooling-only coils to heat-pump coils. A new, smaller, inline fan will be installed in place of demolished fan above men’s locker. New diffusers and grilles will be installed in-place of demolished diffusers and grilles

In 2014, there were illicit discharges containing Polychlorinated Biphenyls (PCBs) to the collection systems conveying wastewater to the Mallard Creek Water Reclamation Facility (WRF) and to the McAlpine Creek Wastewater Management Facility (WWMF). The concentrations of PCBs found in various unit processes at these facilities were above the 50 parts per million (ppm) threshold and, as a result, they are considered contaminated per the Toxic Substance Control Act (TSCA). A project to decontaminate portions of the Mallard Creek WRF is in progress under a separate contract.  The scope of work for that project does not include all infrastructure within the facility or any portion of the collection system.

Charlotte Water identified the location where the contaminant was discharged to the Mallard Creek collection system and, as a result, has been able to delineate the limits of contaminated infrastructure which includes 8.7 miles of 24-inch or less piping and 181 manholes. The discharge point for McAlpine Creek, however, could not be located.

SCOPE

This section will provide a general description 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 Service Provider.

Charlotte Water will issue task orders to the Service Provider for projects in various locations with unique scopes of work related to PCB handling.  Projects may happen concurrently or one at a time, and their duration may be short-term or long-term. The project scope may involve work on equipment, concrete structures, metal infrastructure, piping systems, filters, and soils and in various environments like confined spaces, open basins, buildings, and sewer right-of-ways. The Service Provider may be asked to provide services including but not limited to removal, handling, transportation, and/or proper disposal of all materials including PCB contaminated materials in accordance with the requirements of TSCA and other regulations. The Service Provider shall manage all aspects of the work including the work performed by subcontractors and provide all labor, materials, chemicals, supplies, temporary facilities, access provisions, permitting (transportation and disposal related), equipment, delivery and incidentals required for the execution of task orders.

The task order process will involve significant coordination with Charlotte Water, the Service Provider and subcontractors. The Service Provider can also expect to coordinate with other Charlotte Water contractors if the decontamination work is part of a larger project that Charlotte Water is executing.  Charlotte Water may require task orders be priced on a lump sum or time and materials basis depending on what is in the best interest of the City.

This project consists of constructing two new elevated storage tanks. The first tank will be called the Woodlawn Tank with a size of 3 MG (million gallons).    The second tank will be called the Sunset Tank with a size of 2 MG (million gallons). There will be waterline work associated to extend the mainlines to the tank site. The construction site will require grading and clearing in preparation of the tank installation.

Phase II Animal Care & Control renovations will address non-compliant issues per the NC Department of Agriculture and Consumer Services, Animal Welfare Section (NCDA&CS) Inspection reports issued in 2018, 2020, and 2021. Phase II will address renovations for separation of species, inadequate ventilation surfaces not impervious to moisture, slab repair, additional square footage for dog and cat housing, and if funding is available fencing and gate replacement for dog kennels. This phase also will address ADA Barrier renovations to meet international ADA code requirements.

The facility is located at 8315 Byrum Drive, near the airport. This facility is just under 30 years old and the renovations required are a direct response to the NCDA&CS inspection reports. Also, the project will incorporate renovations to address ADA barriers in the facility, such as door hardware, signs, plumbing, minor parking lot curbing, etc.

CMPD background checks will be required for all construction staff, vendors, and anyone occupying the site during construction and deliveries.

The City is seeking bids from qualified vendors to install traffic signs within the city limits. This request for proposals is to select a qualified vendor for the installation of street signs.

The installation of traffic signs will follow methods that are set in the 2018 NCDOT Standard Specification 900, 903, & 904.

While the City is flexible with respect to certain elements of the Traffic Sign Installation Services, the City has specific requirements and preferences for the Service delivery method.
