The work for the completion of this contract entailed inspecting and videotaping storm drain lines; installing
cured -in -place and spiral wound lining within existing storm drains; repairing pipe sections; installing a
manhole access to a junction structure; pruning and removing debris, plants and trees; and replacing a
storm drain trash rack. 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.
