STAFF REPORT

When Hospitality Lane was originally constructed, the
top H" of pavement was omitted due to the many street cuts that
would be needed. This project repaired the failed portions, and
placed the final H" of the design structural section.

of Hospitality Lane
which necessitated

the
The existing soil beneath the pavement on Hospitality
Lane was found to be excessively wet in several areas, due to
leaking water and irrigation lines. The existing subgrade could
not be compacted, as required by the specifications, in order to
carry traffic loads. In order to stabilize the subgrade and
bridge over the saturated material below, 2 feet of unsuitable
material was excavated, and a geo grid stabilization mat was
laid.
o
Change Order No. Five authorizes the Contractor to ex-
cavate the unsuitable material and lay the mat in a 1600 square
yard area, on a time and material basis, at an additional cost
of $7,665.22. The total estimated project estimate, based upon
the actual low bid price, included an amount of $23,036.25 for
contingencies, which can be used to finance the cost of this
change order.
All work under this contract, including the change
orders, was satisfactorily completed as of 2-28-89. Change
Orders No. One and Two authorized the installation of a 12"
pipeline for water from Gage Canal wells. Change Orders Nos.
Three and Four authorized the replacement of failed section of
curb and gutter and installation of a conduit to serve a
relocated street light. The conduit was installed under this
contract since it would be less expensive, than coming back
later after the street was paved.
The contract was awarded for the low bid price of
$150,263.75. Change Orders One through Five increased the
contract price to $186,592.47. The actual final contract price
is $182,081.10, due to a lesser quantity of repairing street
cuts actually being done than the estimated quantity in the bid
documents.
o
Tri-City Corporation, Gage Canal Company and the City of
Riverside are funding two-thirds of the cost of Change Orders
No. One and Two. Therefore, the final cost to the City is
$163,994.43, leaving a balance of $9,305.57 (or 40%) remaining
in the contingency funds.
