During the recent drought, state regulations were enacted prohibiting use of potable water
to irrigate medians planted with turf grass. To comply with this new requirement as well
as reduce water demand, the irrigation on this median was turned off and staff proposed
this project to remove the existing turf grass and replace it with a new California friendly
drought tolerant landscape palette.
The work necessary for the completion of this contract consisted of clearing and grubbing,
landscape replacement and maintenance, irrigation system improvements, and all other
incidental items of work necessary to complete the work in place.
The contracted work has been completed to the satisfaction of the Public Works
Department. A summary of the construction cost is as follows:
Original bid amount:
$501,089.61
Actual Cost of Bid Items Constructed:
$494,688.15
Total Change Orders:
$11,844.76
Final Contract Cost:
$506,532.91
Less plants were needed than originally estimated, resulting in a $6,401.46 cost
reduction. In an effort to reduce initial project cost, the project strived to reuse the majority
of the existing irrigation system rather than installing a completely new system. However,
additional minor modifications to the irrigation system were required once construction
began to insure the system was sound and operated within expectations. Four change
orders totaling $11,844.76 were approved that were related to modifications to the
existing irrigation system. With the completion of the project, the final contract cost is
approximately 1.1 percent above the original bid amount.
A summary of the project schedule is as follows:
Estimated Start of Construction per Annual Baseline Schedule November 26, 2018
Actual Start of Construction Per Notice to Proceed December 3, 2018
Extended Contract Completion Date Inclusive of Extra Work March 18, 2019
Actual Substantial Construction Completion Date March 11, 2019

improvements completed to the satisfaction of the Public Works Department. Due to

was extended to March 18, 2019.
