RECOMMENDATION: That the Board of Public Utilities approves the capital expenditures of $579,000 for Work Order No, 0913727 (Water), $212,626 for Work Order No. 0917745 (Electric) and $153,014 for Work Order No. 1015016 (Street Lights), which includes all design, construction, change order contingencies, system connections, construction management, inspection and geotechnical testing for the Water and Electric System Improvements as part of the Collett Avenue Extension Project. BACKGROUND: On January 22, 2014, the Public Works Department (PW) opened construction bids for the Collett Avenue Extension Project — Bid No. 7190. The project will generally involve the construction of new street improvements along the missing segment of Collett Avenue between Buchanan Street and Pierce Street. The work will include the construction of new curb, gutter, sidewalk, landscaping and asphalt paving, as well as installation of various underground utilities. It is anticipated that this street improvement project will enhance traffic circulation along the City of Riverside's western boundary. This project is located in a hilly region of the City. Due to the extensive grading required to construct the new roadway, Riverside Public Utilities' (RPU) Water and Electric System Improvements were combined with the overall street improvement project. RPU's Water System Improvements will generally entail the construction of approximately 1,660 linear feet of 12 -inch ductile iron pipe, 650 linear feet of 8 -inch ductile iron pipe, two fire hydrants, and all other related fittings and appurtenances. This project falls along the boundary between the 925 and 1100 Pressure Zones. The 12 -inch and 8 -inch pipelines will be part of separate pressure zones. These system improvements will bolster the existing water system by providing additional looping and redundancy in the 925 Pressure Zone, in addition to providing water service and fire protection for future developments along Collett Avenue. RPU's Electric System Improvements include intercepting and extending existing underground infrastructures, installing a pad- mounted structure, transformer and providing new cable installations to provide a three phase loop feed south to Madera Way, as well as installation of new street lights. PW received six bids for this project. The lowest responsive bid was submitted by Griffith Company, of Brea, California, in the amount of $2,563,794.18. The City Council is scheduled to consider this the award of the construction contract during their regular meeting on February 25, 2014.
