W A T E R E N E R 6 Y 1. 1 F 6 RIVERSIDE PUBLIC UTILITIES L�a.- III& Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: February 15, 2013 ITEM NO: 3 SUBJECT: FIRST AMENDMENT TO THE PROFESSIONAL SERVICES AGREEMENT FOR CONSULTANT SERVICES FOR THE DESIGN AND CONSTRUCTION OF THE EXPANDED GAGE EXCHANGE BOOSTER PUMP STATION PROJECT ISSUE: The item for Board of Public Utilities consideration is approval of the First Amendment to the Professional Services Agreement with Krieger 8 Stewart, Inc. for additional engineering design and construction management services for the Expanded Gage Exchange Booster Pump Station Project. RECOMMENDATION: That the Board of Public Utilities approve the First Amendment to the Professional Services Agreement with Krieger & Stewart, Inc. in a not-to-exceed amount of $258,564 for additional engineering design and construction management services for the Expanded Gage Exchange Booster Pump Station Project. BACKGROUND: The Riverside Public Utilities (RPU) initiated a water exchange program with the Gage Canal Company (Gage)in 1991 to augment its domestic water supply. Under the program,RPU may exchange Gage's share of water supply from Bunker Hill Basin for irrigation water from the Riverside Canal. Currently, Riverside Canal water is delivered from the Olivewood Booster Station to a location behind Riverside Poly High School, bypassing two major customers, University of California Riverside (UCR) and the Canyon Crest Golf Club. The Expanded Gage Exchange Project will construct facilities to deliver water upstream of UCR and the Canyon Crest Golf Club enabling RPU to take additional water from the Gage Canal to use for domestic purposes. On April 6,2012,the Board of Public Utilities approved a Professional Services Agreement in the amount of $616,000 with Krieger&Stewart, Inc.for engineering and construction management services for the Booster Pump Station component of this project. Over the course of the design phase,various enhancements were made to the original Booster Pump Station concept. Many of these variations came about from collaboration between RPU staff and the engineering consultant to develop methods to automate and improve various operational and maintenance aspects of the booster station, largely based on staffs experience with the Olivewood Booster Station and the challenges associated with conveying canal water, which can contain significant organic and inorganic debris. The alterations to the design are expected to reduce the long term operational and maintenance costs of the new facility. The enhancements noted above entailed an additional engineering design effort that was not included in the original scope of services. The cost for these additional engineering services is $93,733. Included in the contract with Krieger and Stewart is an optional task for construction management services. With the changes to the design, staff recognized that the contract duration may increase by a few months. Krieger 8 Stewart, Inc. has provided a revised proposal in the amount of$444,977,which reflects an increase of $984,831 to the construction management services fee, if RPU elects to exercise this option.
