CITY OF SAN BERtt",RDINO - REQUEST "'~R COUNCIL ACTION
STAFF REPORT
During construction, an unknown underground waterline and
a sewer lateral were encountered during the pipe jacking
operation. The water line was repaired and protected for a cost
of $658.03. The bootleg sewer lateral flooded the Contractor's
operation resulting in the loss of one day's production, totaling
$6,114.56 in costs.
Addi tionally, the native material used for backfilling
the trench in Mill Street was deemed unsuitable, due to the
Contractor being unable to obtain specified compaction. Our soil
consultant was unable to determine the unsuitability prior to the
Contractor's efforts to obtain compaction. Al though the
Contractor sustained substantial additional costs, we have
determined that $ 5,790 was beyond his contractual obligation.
Change Order No. Four will authorize the Contractor to perform
these items of extra work, at a net increase in the contract cost
of $12,562.59.
The total project budget included an amount of $69,509
for contingencies, which can be used to finance the additional
costs for the change orders.
The work was satisfactorily completed as of 6-14-89. The
contract was awarded for the low bid price of $434,091.00.
Change Orders One through Four authorized a net increase in the
contract price of $15,470.07 to $449,561.07. The actual final
contract price is $ 451,030.68, due to some variations in the
actual final quantities from the estimated quantities.
We recommend that the work be approved and accepted, and
that final payment be authorized. Also, that Change Order No. 4
be approved.
