Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an agreement with Burgess & Niple, Inc., in the amount of $4,259,792.00, for professional engineering services for the Hap Cremean Water Plant (HCWP) Treatment Improvements Project.
Modifications to the Hap Cremean Water Plant (HCWP) treatment process are necessary to comply with new rules promulgated by the Ohio Environmental Protection Agency set forth in the Stage 2 Disinfection By-Product Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. This contract is for professional services for detailed design of treatment improvements selected from several pilot studies conducted in a previous contract at the Hap Cremean Water Plant. The new improvements will give the City the capability to remain in compliance with OEPA rules for drinking water.
Work to be performed under this agreement will be completed in two phases: Preliminary Engineering and Detailed Design. The agreement will need to be modified in order to provide for a third phase, Services During Construction.
Preliminary Engineering: Work under this phase will include the evaluation and analysis of four layout options, including the evaluation of two oxygen source alternatives (bulk liquid oxygen and ambient air for on-site generation of high purity oxygen gas), and two ozone feed injection alternatives (fine bubble diffusion and high efficiency injection). Elements of this phase of work will include various meetings and workshops; value engineering; survey and mapping of the project site; geotechnical investigations; design drawings (50 percent); and a Preliminary Design Report (PDR). The option analysis will include preliminary construction cost estimates; probable annual operating, maintenance, and repair costs; a present worth analysis; basis of design narrative; construction phasing, general operational descriptions, preliminary hydraulics analysis, and a preliminary sc...
