CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION
STAFF REPORT
The contractor for Phase III of the Northwest Interceptor Sewer
encountered a 15X18-inch storm drain in the Base Line Street
Intersection that was not shown on the plans, or in our records.
This storm drain conveys water from the northwest corner to the
southeast corner of this intersection.
It was necessary to relocate about 100 feet of this storm drain, in
order to allow for construction of the interceptor sewer in
accordance with the plans and install a manhole for the storm
drain. This work was performed on a time and material basis, at a
total cost of $9, 739 . 01.
The trench for the interceptor sewer is located a short distance
from the west curb line of Medical Center Drive. A bus stop is
located on the west side of Medical Center Drive, south of Base
Line Street. After excavating the trench in this area for the
sewer, it was found that the intervening strip of pavement was
badly broken due to the loads imposed by the buses.
It was, therefore, necessary for the contractor to remove this
strip of broken pavement and replace as a part of the trench
restoration effort. This extra work was performed on a time and
material basis, at a total actual cost of $6, 885. 37 .
The total estimated project cost, based upon the actual low bid
price, included an amount of $55, 294 . 00 for contingencies, which
can be used to finance the cost of this extra work.
All costs incurred for these Change Orders will be charged to
Account No. 245-365-5504-1528 .
We recommend that Change Orders No. ONE and TWO be approved.
