The work occurred primarily along Back Bay Drive and Bayview Way. The contract was completed to the satisfaction of the Public Works Department. A summary of the contract cost is as follows: Original bid amount: $ 426,518.00 Actual cost of bid items constructed: $ 388,048.30 Total change orders: $ 21,330.58 Final contract cost: $ 409,378.88 Prior to construction, Burtech requested a material substitution using spiral wound technology for lining the storm drain pipes that would yield cost savings. Following the initial investigation, about half the pipes could use this new lining system. A credit of $15,008.04 was issued using the spiral wound method. In addition, some of the actual bid quantities of pipe were less than originally estimated after the debris and vegetation were cleared for construction. Four other change orders were executed. Two related to the extra work necessary to reline the storm drains along Back Bay Drive. Due to the favorable storm drain lining unit prices received, the third and fourth change orders were developed to reline other known deteriorated storm drain sections located along East Coast Highway, Begonia Avenue, and De Anza Drive. A summary of the project schedule is as follows: Estimated Completion Date per 2014 -2015 Baseline Schedule April 20, 2015 Project Awarded for Construction October 14, 2014 Contract Completion Date with Approved Extensions April 10, 2015 Actual Substantial Construction Completion Date April 7, 2015 ENVIRONMENTAL REVIEW: Staff recommends the City Council find this project exempt from the California Environmental Quality Act ( "CEQA ") pursuant to Section 15302(c) (Construction resulting in no expansion of facility capacity) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential to have a significant effect on the environment.
