Although the total project is over budget, the project is under budget for Fiscal
Year 1991-92 ($1,042,510 budgeted; $961,680.04 will be expended, including the
retention).
DESCRIPTION: In November, 1990, the City Council awarded Contract
90-01, San Ramon Road Improvements Phase IV, to Redgwick Construction. The project
was the final phase of improvements on San Ramon Road. This project widened the
original two-lane road to four lanes between Silvergate Drive and Vomac Road and
added landscaped medians, street lighting, a bike path, and replacement of the
traffic signal at Shannon Avenue. Included in the Phase IV Improvements budget was
a soils study of the hillside slopes in the right-of-way west of the road and north
of Shannon Park.
The soils study on the hillside was undertaken to investigate the stability of the
slope in its existing condition as well as anticipated conditions should landscaping
and irrigation be introduced. The results of the study indicated that the slope is
stable under dry static conditions. It was recommended that mitigative work such as
reconfiguring and recompacting the slope with drains, or the placement of a buttress
fill be undertaken. The purpose of this was to address the fact that the slope
could be unstable under dynamic (earthquake) conditions and the stability would be
lessened by slope irrigation. The cost of any project to strengthen this slope will
have to be addressed in future Capital Improvement Programs.
The completion of the project was delayed through the City's request of the
contractor to postpone landscape planting last summer due to extreme drought
conditions. When the contractor resumed his planting schedule in the fall and
winter, some of the specified material was not available, thereby further delaying
the project's completion. This eight-month time extension is reflected in the
increase of inspection and resident engineer costs, however, this was partially
offset by a maintenance savings of approximately $22,750. During the time
extension, Staff still had to have an inspector and a resident engineer assigned to
the project at reduced hours as the contractor was still performing sporadic work.
The project is funded in part with Federal Aid Urban funds, which were increased
from the City's own share by purchase of additinal funds from Foster City and San
Luis Obispo. These funds were purchased at a discount which allowed the City to
reduce local funding sources.
The City Engineer has reviewed the improvements and found them to be in conformity
with the plans, specifications and special provisions. The landscaping
subcontractor has filed a stop notice for withholding payment of $76,032.18. The
prime contractor has provided a bond for 125% of that amount, which covers the
amount owed plus legal fees if the stop notice is not resolved. Since the
contractor posted securities of deposit in lieu of retention, Staff recommends that
the City Council authorize Staff to release the securities and also make the final
progress payment in the amount of $15,326.64 to Redgwick Construction.
