STAFF REPORT
During the construction of the miscellaneous concrete for
the rehabilitation of Arrowhead Avenue, the actual quantities
placed exceeded the estimated quantities in the contract by over
125% , or in excess of 90 cubic yards. The additional 48 cubic
yards of concrete placed was performed by the contractor on a
time and material basis , as provided in the standard specifica-
tions .
In reviewing the estimated quantities for miscellaneous
concrete, curb and gutter, sidewalks and handicap ramps, it was
determined that the estimated quantities in the Bid Schedule did
not accurately reflect the amount of work shown on the plans.
The quantity of concrete required for the 460 lineal feet
of curb and gutter was estimated per the standard plans , with an
18-inch wide gutter. However, the actual width of the existing
gutter on Arrowhead Avenue was 30 inches . The estimated bid
calculations for the placement of 20 handicap ramps on Arrowhead
Avenue was incorrect, since it appears that the estimate did not
include the replacement of the existing concrete apron. Also,
there were additional areas of sidewalk that needed to be
replaced, that had not been indicated on the plans. This
resulted in a total of 138 cubic yards of concrete actually
placed in lieu of the 72 cubic yards estimated in the contract
documents .
The work involved in placing the extra 48 cubic yards was
performed on a time and material basis, as provided in Section 4-
103, "changes" in the State of California Standard Specifica-
tions.
The total estimated project cost included an amount of
$106 ,587 for contingencies, which can be used to finance the
additional cost for this change order.
Federal-Aid Surface Transportation Funds (STP) have been
approved to finance approximately 88% of the total project cost,
including any required extra work. Caltrans oversees Federal-Aid
funded projects to insure compliance with all applicable federal
requirements. Their representative has reviewed this extra work,
and determined that it is eligible for Federal-Aid funds .
Since the contractor is entitled, by terms of the
contract, to be compensated for any extra work required in the
construction of the project, we recommend that Change Order No. 2
be approved.
