The property is <br />owned by the City for water production, storage, and pumping purposes. The existing pumps <br />boost stored groundwater to the City's main distribution pressure zone. A 55- year -old masonry <br />structure is located just south of the pumps, and houses the pump station electrical equipment, <br />as well as an office and shop facilities, but does not house or shield the pumps themselves, <br />which are outdoors and exposed to the elements. Moreover, the building does not meet current <br />codes and does not provide sufficient space for operation and maintenance activities. <br />The scope of work to replace the aging building includes new piping, pumping, structural, <br />mechanical, and electrical works. The improvement consists of re- routing 24 -inch piping, new <br />discharge heads on pumps, new pump impellers, a new brick building, HVAC systems, <br />ventilation systems, monorail crane hoist system, new transformer, switchgear and motor control <br />centers, well controls, replacement of existing conduits, building electrical and lighting, and <br />23A -1 <br />
