(November 16, 2010)
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Director of Public Works
Subject: Approve Change Order No. 3 with Barson Utilities for the water

Action
Requested: Approve Change Order No. 3 with Barson Utilities for the water and
sanitary sewer relocations on FM1709 for the median and
deceleration lane project in the amount of $40,177.80
Background
Information: The 1999 Traffic Management Bond referendum authorized
funding for the right turn deceleration lanes. This includes funding
for engineering design, right -of- way /easement acquisition,
relocation of utilities, and construction of the right turn
deceleration lanes. This construction project to relocate the water
and sanitary sewer utilities is necessary to provide working space
for construction of the right turn deceleration lanes. The FM1709
median and deceleration lane project is currently under
construction.
With the acquisition of easements for the deceleration lane
project, the city agreed to provide a 6' tall wrought iron fence for a
property owner along Southlake Boulevard. The fence is included
in this change order.
Also included in the change order are the costs for an emergency
repair of the 20 -inch water line along the north side of Southlake
Boulevard. Due to concerns that the 20 -inch line could be in
jeopardy brought about by large amounts of water percolating
through the ground, emergency work was undertaken on
November 8, 2010. While all preliminary investigation pointed to
a leak in the 20 -inch water line, excavation yielded no such
problem. The contractor will also install an additional 20" valve
on the existing 20 -inch water line.
The remaining utility relocations to be completed by the contractor
for this project are located at Jellico West and Jellico East and
have been delayed due the easement acquisitions, and the City's
restriction during the peak water usage time between May and
October of each year. The contractor has remobilized to complete
the remaining work, and has the ability to repair the existing leak
with this contract.
Financial
Considerations: The total amount of Change Order No. 3 is $40,177.80. This will
increase the total contract amount to $591,558.05. Funds for
installation of the fence are currently available from the 1999
Traffic Management Bond fund in conjunction with the deceleration
lane project. Funds for the repair of the 20 -inch water line are
available in the Public Works operating budget.
Previous Contract Amount $551,380.25
Proposed Change Order No. 3 $40,177.80
Total Contract Amount $591,558.05
Strategic Link: The relocation of the existing water and sanitary sewer lines and
