DESCRIPTION:
In August, 1986, the City Council awarded Contract 86-6 San
Ramon Road Phase II Street Reconstruction, Traffic Signal, Street Lighting,
and Landscaping, to Gradeway Construction, Inc. This project widened San
Ramon Road between 1-580 and Silvergate Drive, upgraded the signals at
Dublin Blvd. and at Amador Valley Blvd., constructed a signal at Silvergate
Drive, and constructed medians and landscaping.
This project was an extremely complicated roadway project. The
funding included Federal Aid monies from three different funds, offsite
improvement fees from four different private developments, and contributions
from parcels within the San Ramon Road Specific Plan Assessment District.
Among the public agencies involved in the review and approval process were
State Fish and Game for work on Martin Canyon Creek, Caltrans as a conduit
for the FAU process and for encroachments into the State right-of-way, and
FHWA approvals for FAU funding.
Some of the existing street roadway from side to side as well as
the entire Silvergate Drive and Amador Valley Boulevard intersections
required reconstruction in multiple traffic phases. The work at the San
Ramon Road/Dublin Boulevard intersection had to be performed within an
intersection with the highest traffic load in the City. The City contracted
with a private security company to aid traffic into and out of the local
businesses to try to minimize impacts on these businesses.
After the contract was awarded, Staff redesigned some of the
drainage system to reduce the cost of the project, because the low bid was
substantially over the engineer's estimate. Additional savings were made in
some areas where a cement treated base was found under the existing asphalt.
In these areas, some of the grades and the structural section were
redesigned to utilize this base.
These savings offset other additional costs for unforeseen
conditions that arose during construction. An additional two street lights
were replaced on Dublin Boulevard west of San Ramon Road (double sodium
vapor lights replacing single mercury vapor lights). A revision was made
adding an additional right turn lane northbound off San Ramon Road to
eastbound Dublin Boulevard. This required revisions to the signal system
and pavement striping. The need had been identified through TJ¥~ studies on
the Downtown Plan and the studies at the west end of town. The two banner
poles were also painted to match the brown street light poles.
The City Engineer has reviewed the work and determined that it
is complete and in accordance with the approved plans, specifications, and
modifications. Staff recommends that the City Council accept the
improvements and authorize release of securities held in lieu of retention.
