December 4, 2000 Subject Award of Contract - Redwood Shores Street System Improvements Project Engineering File No. 803-02 Recommendation Adopt a resolution awarding the contract for Redwood Shores Street System Improvements Project, to the lowest responsible bidder, RGW Construction, Inc. of Livermore, California, for their low bid of $2,229,323.55. Background The majority of this project is the non-Caltrans portion of the improvements that will be funded by the Redwood Shores Community District No. 99-1, commonly referred to as Shores Transportation Improvement District (STID). This portion of the contract covers the improvements to the local streets, primarily at intersections. Because the majority of delays are caused by inefficiencies at intersections (especially turning movements), making improvements at these locations should improve the overall efficiency of the system, which feeds and receives traffic to and from the freeway. The improvements proposed include additional turn lanes; converting through lanes into turn lanes; traffic signal modifications, and lengthening of turn lanes. In addition, the drainage and roadway surface within the project areas will be reconciled as needed. This project involves improvement to four intersections, as follows: ~ Marine Parkway at Twin Dolphin Drive ~ Marine Parkway at Bridge Parkway ~ Marine Parkway at Oracle East Street ~ Redwood Shores Parkway and Bridge Parkway The first two locations are entirely within the scope of work of the STID, and will be funded as such. Improvements at the Oracle East intersection will be funded partly by Oracle and partly by GID 1-64. The last intersection is mostly STID work (except for the signal work), which will be funded by GID 1-64, and done at a later time. On July 24, 2000, the City Council approved the Contract Documents and authorized the advertisement for bids for this project. More information was presented in that Staff Report, which is attached for your information. Originally, the bid opening was set for August 30, 2000, however, it had to be delayed to accommodate the redesign of the Redwood Shores Parkway/Bridge Parkway intersection. This redesign was prompted by input from residents who were not convinced that the traffic volume at this intersection would warrant an additional left-turn lane from east-bound Redwood Shores Parkway onto Bridge Parkway. Traffic counts revealed that this is a borderline case, and the turn lane was lengthened in-lieu-of adding another one. '»;'"-"»--"'T""""
