The pump station provides domestic water service and fire flow to the 565 pressure zone. In addition to the pump station, the City has two (2) large reservoirs located on the property. RH2 Engineering, Inc., (RH2) and the City are currently working on a Master Site Plan for improvements to this facility that includes construction of a new 435 Pressure Zone water reservoir, replacement of the existing 435 Pressure Zone Reservoir, replacement of the existing 565 Pressure Zone Reservoir, and the replacement of the Highlands water pump station. Preliminary work on the Master Site Plan has identified that the existing portable generator that provides standby emergency power to the facilities needs to be replaced with a permanent generator. In addition to the generator replacement project, the Master Plan has identified that the City’s VHF radio equipment that provides the primary “push-to-talk” radio system for the entire City is located at this site and needs relocation to accommodate future construction plans. As part of this project, the City desires to: Increase reliability of the pumping facility by replacing the existing portable generator with a permanent generator sized for current and future electrical loads. Store five (5) days of diesel fuel on-site in a dual containment storage tank that can be relocated at a future date. Provide a permanent load bank attached to the generator for use during on-site testing. Provide a weather shelter over the proposed permanent generator. Replace the existing Automatic Transfer Switch (ATS) and the feeder conductors. Upgrade the west room of the old chlorination building to make it suitable for locating the VHF radio equipment. Relocate the existing VHF radio equipment. Extend fiber optics communications to the old chlorination building for use by the Signal Department. Demolition of the two (2) small buildings, located in the northwest corner of the property after the VHF radio equipment is relocated. Provide two (2) spare 2-inch conduits from the proposed Radio room to the top of the existing elevated reservoir for future video surveillance cameras. The following lists other improvements for the City’s Information Technology (IT) department included in this project: Provide a generator backed power feeder from existing water pump station to the existing WiFi radio system cabinet. Provide spare 2-inch conduit from the existing WiFi radio system cabinet to the proposed Radio room for future Ethernet connection by the IT department. Provide spare 2-inch conduit from the existing water pump station to Radio room for future Ethernet connection to Water department supervisory control and data acquisition (SCADA) system. Provide an Ethernet switch cabinet that is 24 inches tall by 24 inches wide by 28 inches deep that matches IT department specifications in the proposed Radio room for installation of an Ethernet Switch in the future. Identified below is a list of tasks RH2 will perform with objectives, approaches, deliverables, as well as information and participation needed from the City. Within each task, to the level warranted by that task, RH2 will perform project management, including staff scheduling, invoicing, record keeping and filing, and periodic coordination with the City to facilitate the project. This Scope of Work is intended to cover the work necessary to complete the final design, assist with permitting and bid the project.
