BACKGROUND The El Charro Road and 1-580 Interchange was built in 2009, and will become the new east entrance to the City of Pleasanton with the completion of the Stoneridge Drive extension in the fall of 2013. Caltrans installed basic groundcover for the intersection, leaving detailed landscaping to the individual cities to coordinate. The City of Dublin landscaped the north quadrants of the interchange in February 2010, and Livermore is scheduled to complete the landscaping of the southeast quadrant in early 2013. Gates + Associates of San Ramon designed the project and will continue construction support, if necessary. The intent of the proposed design was to create a complementary style to the Livermore landscaping, creating a seamless appearance to the two quadrants. See Attachment 3 for illustration of the landscaping. The City Council awarded the design contract to Gates + Associates in August 2012 for the amount of $49,208. Topographical survey work by Alexander & Associates was also required to complete the design. The work includes traffic control, water pollution control, environmental stewardship, clearing and grubbing, earthwork, importing soil, directional boring and sleeves, irrigation, soil preparation, soil amendments, fertilizers, headers, mulch, planting, hydroseed, and 90-day maintenance. Landscaping maintenance after the 90-day period will become the City's responsibility. A maintenance agreement will be set up with Caltrans as this area is within Caltrans' right of way. Due to Caltrans' limited maintenance program, staff has determined it is in the City's best interest to maintain the area ourselves. DISCUSSION Bids The engineer's estimate for the project was $360,000. Sealed bids were opened on December 17, 2012. Thirteen responsive bids were received that ranged from $291,301 to $413,997 (see Attachment 1). The low bid was received from Bortolussi & Watkin, Inc. of San Rafael, California. All bid documents were found tc be in order, and past work performed by Bortolussi & Watkin was verified to be satisfactory. Staff recommends award of the construction contract to the lowest responsible bidder, Bortolussi & Watkin, Inc. Budget The total programmed budget for this project (CIP No. 115023) is $488,358, including $138,358 of RM2 funding. Staff recommends that the contingency amount for this project be set at 10% of the construction contract to cover unknown underground utility conflicts. A summary of funding and estimated expenditures is presented in Attachment 2. Page 2 of 3
