Renovation of a parking garage in West Columbia, South Carolina. Completed plans call for the renovation of a parking garage.

The Airport is soliciting proposals from qualified firms to design, and construct (Design-Build) a new photovoltaic (PV) energy production system on the existing parking garage at the Columbia Metropolitan Airport (CAE). The project will include the design, permitting, and construction of an estimated 3.25 MW DC PV array with canopy system . Question Deadline 05/09/2025 Scope of Work The Columbia Metropolitan Airport (CAE) Terminal is supplied power by a 2500 kVA transformer to a metered electrical service with emergency power provided to select panels by an 800 kVA Generator. The Terminal average monthly power use is 562,600 kWh with a maximum and minimum of 744,200 kWh and 310,000 kWh respectively and an annual use of 8.37 MWh. This project consists of new canopy structure(s) to be installed on the existing roof level of the Columbia Metropolitan Airport (CAE) parking garage. The structure(s) will be designed to support both separate under-canopy lighting and a photovoltaic (PV) solar system for energy generation as well as gutters and other utilities. The existing CAE terminal and associated electrical service provided by Dominion Energy, Inc. is existing and will remain and be modified by this expansion. The main utility transformer for the airport terminal will be modified to support interconnection requirements between the utility and new PV system. The existing parking garage distribution system will be modified to support new under-canopy lighting. A utility corridor will be constructed from the parking garage to the facility main switch board to interconnect with the existing switchgear. This project will include local, state and federal funding and include the required provisions related to AIP funded projects. These requirements are included in this RFP. This RFP includes three (3) general options for the development of the Parking Garage PV system. The generation of power between the three (3) options and the interconnection with the existing switchgear are unchanged. The following options correspond to a bid schedule located in the bid form • Option 1 (Bid Schedule 1) – The option includes the installation of equipment and structure necessary to generate the required power and covers only the parking stalls in general. This approach does not include additional canopy construction outside of what is necessary for the installation of solar panels. See narratives and drawings for additional information. • Option 2 (Bid Schedule 2) – The option includes the installation of equipment and structure necessary to generate the required power and covers the entirety of the top floor of the garage and is constructed using a single plain with the low edge on the south side of the garage and the high edge located on the North edge. See narratives and drawings for additional information. • Option 3 (Bid Schedule 3) – The option includes the installation of equipment and structure necessary to generate the required power and covers the entirety of the top floor of the garage and is constructed using a “sawtooth” or stepped construction method with the low edge on the south side and the structure resetting to a similar elevation after each bay of parking. This method should result in a lower overall structure height. See narratives and drawings for additional information. B. Size of Offering The maximum capacity established by the local utility for the PV Systems are established at approximately 3.25 MW DC PV array with a canopy system that will cover approximately 270,000 square feet of deck.\ C. Site Description The project includes three general areas of construction, work within the existing parking garage, construction of the utility corridor from the Parking Garage to the Existing Switchgear and the Existing Switchgear Room. The parking garage includes three (3) levels of parking with the top deck approximately 270,000 square feet. The utility corridor includes grassed and paved areas and crosses roadways that are unable to be completely closed. The Airport is a 24hr/7 Day a week operation that requires the circulation of the traveling public, Airline/Tenant staff and support vehicles at all times. A portion of the project will be constructed inside of the Airport Operations Area (AOA) and requires the badging of contractor staff to complete construction within the AOA. Additional information for badging is available at Badging and Training – Columbia Metropolitan Airport. D. Permits The selected BIDDER will be solely responsible for obtaining any, and all, Federal, State, and local permits, approvals, and licenses required.
