Award a contract for the construction of the Canyon Crest 16-Inch Water Transmission Main Replacement Project, Bid No. 6936, to the lowest responsive bidder,VCI Construction of Upland, California, in the amount of$671,881. BACKGROUND: The proposed work is part of Riverside Public Utilities' (RPU) ongoing water main replacement program to replace aging and undersized water mains and improve fire protection. In particular, the Canyon Crest Transmission Main Pipeline is a key north-south transmission facility serving the upper pressure zones. The existing 16-inch pipeline material is cement mortar lined welded steel and was installed in 1960.This pipeline has experienced numerous leaks in recent years, requiring frequent closure of the street that serves as a gateway to the University of California, Riverside south campus. The proposed work entails the construction of approximately 3,300 linear feet of 16-inch ductile iron pipe,50 linear feet of 12-inch ductile iron pipe, as well as all other related frttings and appurtenances. City field forces will perform the system connections. The project is located within Canyon Crest Drive between El Cerrito Drive and Martin Luther King Boulevard (Attachment 1). Construction of the proposed improvements will be coordinated with street closures and transportation of the Southern California Edison (SCE) steam generation units as they move through Riverside.
