Additionally, the intersections were modified to add left -turn phasing to enhance the left -turn movements during peak summer periods. The contract has now been completed to the satisfaction of the Public Works Department. A summary of the contract cost is as follows: Original bid amount: Actual cost of bid items constructed: Total change orders: Final contract cost: $201,672.00 $202,374.00 $5,881.10 $208,255.10 The final construction contract cost was approximately 3.3% above the original bid amount. The majority of this additional cost increase was related to discovery of unknown underground utilities that required relocation of equipment and installation of additional temporary traffic control equipment. The delay in project completion was due to incorrect traffic signal arms being delivered by the manufacturer. Generally traffic signal poles and arms can take up to 15 weeks to be delivered. Fortunately the vendor was able to quickly locate and deliver the correct equipment to minimize the delay.
