Explanation
1. BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services agreement with Burgess and Niple, Inc. for the Hap Cremean Water Plant (HCWP) Treatment Improvements - Detailed Design Project, for the Division of Power and Water Contract No. 1151.
Work under the original agreement (EL010296, Contract No. 1151, CIP No. 690430-100001) included engineering services for preliminary and detailed design of additional treatment processes that were results of pilot studies conducted prior to design under Auditor's Contract EL006582 (Contract No. 1078, CIP No. 690430-100000).
Under the original agreement, the design team encountered numerous issues with the existing plant that affected the implementation of the new treatment process requiring additional design services that were not anticipated in the original scope of services. This current agreement modification is to perform these additional design services, which consist of:
· Design modifications required for full truck spill containment for new sodium hydroxide system.
· Conduct an evaluation of a system interconnect joining A and B plants, prior to filtration.
· Design a new filter underdrain system including demolition of existing underdrains. Upgrade filter control consoles with local operator interface terminals at each filter.
· Design a pair of additional post-chlorination feed points among the clearwells including new injection and sampling systems with enclosures. Design demolition of existing pre-chlorination feed lines.
· Design connection to existing distribution system for cooling water system to serve the new ozone facilities. This shall include design of approximately 1,600 linear feet of pipeline. Conduct additional surveying of proposed routing of this line.
· Incorporate electrical switchgear monitoring and design electrical improvements associated with an exterior sanitary lift station.
· Design an exte...
