Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering agreement with EMH&T for the Rickenbacker Area Sanitary Pump Station. This pump station (also known as SA-15) is located on the south side of Columbus off of London Groveport Road and is located at 2849 Rickenbacker Parkway West.
Proposed improvements to be investigated shall include, but are not limited to the following: upgrade or replacement of the existing overhead electrical service and associated electrical panels, addition of an electrical transfer switch and generator plug for the existing SMOC trailer mounted generator, and replacement of the existing sanitary pumps, pump well piping, guide rails, and pump controls due to the 20 plus year age of the currently installed system. Newer technology installed at other City pump stations has made the current system obsolete and the new systems are more reliable and easier to maintain and troubleshoot. The consultant shall prepare a design report for the City which contains cost estimates to update the existing equipment. Upon successful review of the report, the consultant will then prepare construction documents and plans to update the pumps and controls at this station.
An ‘Arc Flash Hazard Analysis’ report is required for all City maintained pump stations. The consultant will be tasked to provide an arc flash hazard analysis of their proposed design and include this information with their design report as referenced above. Additionally the City desires to add a SCADA system to provide real time control of all operational functions via the SCADA system to the Sewer Maintenance Operations Center. The consultant shall coordinate with City staff and the City’s Instrumentation and Controls Consultant to investigate and recommend alternatives where installation of flow meters, advanced electronic measurement devices, or sensors would enhance system knowledge thru the SCADA syst...
