The contract provided for the construction of new water mains, valves, and fire hydrants for Balboa Avenue, Collins Avenue and Opal Avenue along with the ancillary concrete pavement replacement. The contract was completed to the satisfaction of the Public Works Department. A summary of this contract's construction cost is as follows: Original bid amount: $1,563,400.00 Actual Cost of Bid Items Constructed: $1,350,458.00 Total Change Orders: $ 98,869.45 Final contract cost: $1,449,327.45 The actual cost of bid items constructed was $212,942.00 less than the original bid amount due to a reduction in the amount of street pavement replacement than originally planned. This is the first of a three-year water replacement project for Balboa Island that focuses on replacing old deteriorated cast iron water mains. With that in mind, staff reduced the pavement replacement limits with the intent to come back after all water replacement work has been completed and address the ultimate pavement work with a larger street and alley pavement replacement project. Three contract change orders were approved as part of the project totaling $98,869.45. The change orders included some additional costs for night work adjacent to the Marine Avenue area and use of rapid set concrete in order to open up alley and streets to traffic within 24-48 hours. Additionally, during the project many of the existing water values were found to be deteriorated and unable to provide water shut-off necessitating contract changes for additional water valve replacements along the N. Bayfront Alley and Balboa Avenue. 10-2 Balboa Island Water Main Replacement Phase I — Notice of Completion of Contract No. 7173-1 (Project No. 16W1 1) May 22, 2018 Page 3 A summary of the project schedule is as follows: Estimated Completion Date per master Schedule June 29, 2018 Project Awarded for Construction November 28, 2017 Notice to Proceed January 2, 2018 Contract Completion Date with Approved Extensions April 20, 2018 Actual Substantial Construction Completion Date March 26, 2018 The project was substantially complete as of March 26, 2018, with all improvements.
