1. BACKGROUND
This Ordinance authorizes the Director of Public Utilities to renew the professional engineering services agreement with CHA Consulting for the Hap Cremean Water Plant (HCWP) Lime and Soda Ash Dust Collection System Improvements Project, CIP #690545-100000, in an amount not to exceed $269,500.00.
This project will make improvements to lime and soda-ash pneumatic conveyance and dust collection at the Hap Cremean Water Plant (e.g., piping, valves, dust collectors, etc.) and lime and soda-ash conveyance support systems (e.g., monitoring system, controls system, etc.). Many of these elements must be controlled for environmental, health, and safety reasons. A majority of the HCWP lime and soda-ash handling equipment, piping and controls are more than thirty years old and are at the end of their useful life. The frequency of lime/soda-ash dust release problems are increasing, impacting the plant’s ability to safely and properly perform chemical unloading. These improvements were recommended in the previously completed preliminary design phase and documented in the HCWP Lime and Soda Ash Dust Collection System Improvements Basis of Design Report.
Work performed to date includes preliminary design and detailed design services. This ordinance provides Engineering Services During Construction (ESDC) phase services for the recommended improvements from the Basis of Design Report and Bid Documents. ESDC phase work will include review of submittals, responding to Requests for Information (RFIs), preparation of Requests for Proposals (RFPs), attending construction review meetings, assisting in negotiations, preparation of standard operating procedures and record documents, and other matters with bid document clarifications as necessary to meet the design intent.
The improvements are directly related to the HCWP treatment process, which services multiple community planning areas (Planning Area - 99 Citywide).
