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. 5-2 Newport Blvd. Widening Notice of Completion for Contract No. 4881 (15R17) October 11, 2016 Page 3 The project also included several change orders for a total amount of $207,704.63, which was approximately 5.2 percent of the original bid amount.
