Action
Requested: Approve Change Order No. 4 with Circle C Construction Company
for the TW King 30 -inch water line to include the Caylor Wholesale
Meter Modification in the amount of $166,700.
Background
Information: On April 21, 2011 the City of Fort Worth requested that the cities of
Southlake and Keller remove and replace an existing 16 -inch
turbine meter from the water line which supplies water to Southlake
and Keller. This is a companion project to the now 42 -inch
ultrasonic meter installed in 2010 -2011. It will provide redundancy
for Fort Worth and allow Southlake and Keller to utilize the capacity
of the 42 -inch water supply line. The turbine meter to be replaced
is located at the Caylor Ground Storage Tank and Meter Station.
The City of Southlake contracted with Freese & Nichols, Inc. to
prepare plans and specifications for the installation of the 36 -inch
Magnetic Meter. Circle C Construction Company is currently under
contract with the City to construct the TW King 30 -inch water supply
line. This proposal is to include the 36 -inch magnetic meter as
Change Order No. 4 to the Circle C Construction Company
contract.
Financial
Considerations: This project is being funded from existing Capital Improvement
Program Utility Fund monies allocated in the City of Fort Worth
Wholesale Meter Modifications Project 00019. Staff recommends
that City Council approve Change Order No. 4 in the amount of
$166,700.00 resulting in a total project cost of $6,907,220.00. Item
4C on the same agenda is related to this agenda item. The city of
Keller will reimburse the City of Southlake for the cost of their
proportionate share of this meter modification. Keller's portion of
the cost is $40,237.93. This change order is within budget for the
TW King 30 -inch water supply line.
Strategic Link: The installation of the 36 -inch Magnetic Meter links to the city's
strategy map relative to the focus areas of Infrastructure,
Performance Management and Service Delivery. The specific
corporate objectives that are met by the construction of these
improvements include: Invest to provide and maintain high quality
public assets and improve performance of delivery and operational
processes.
