The contracted work has now been completed to the satisfaction of the Public Works
Department. A summary of the construction cost is as follows:
Original bid amount:
$3,967,186.45
Actual Cost of Bid Items Constructed:
$3,810,662.02
Total Change Orders:
$207,704.63
Final contract cost:
$4,018,366.65
The actual cost of contract bid items constructed was $156,524.43 less than the original
bid amount. The majority of the cost saving is attributed to the deletion of several bid
items as follows. Staff encountered inconsistent pavement/sub-grade materials and
thicknesses on Newport Boulevard during construction of the recently completed water
transmission main project within the same area of Newport Blvd. As a result, bid items
to over -excavate and stabilize the soil were included with this contract, but were
deemed not necessary as the required soil compaction was achieved in all cases. In
addition, the project site investigation report, which was completed as part of the
environmental phase, identified a potential for the existence of volatile organic
compounds (VOCs) in the existing soil. A bid item was included to handle and dispose
this possibly unsuitable soil. During construction, soil excavation was monitored and
sampled and no concentration of VOCs were detected which led to the deletion of this
bid item.
