Item 4HCITY OF
SOUTH LAKE
MEMORANDUM
(April 15, 2014)
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Director of Public Works
Subject: Approve Change Order No. 1 with Durable Specialties, Inc. for
the Illuminated Street Name Sign and Battery Back-up project
to include the construction of the traffic signal at N. Carroll
Avenue and Federal Way in the amount of $257,410.
Action
Requested: Approve Change Order No. 1 with Durable Specialties, Inc. for the
Illuminated Street Name Sign and Battery Back-up project to
include the construction of the traffic signal at N. Carroll Avenue
and Federal Way in the amount of $257,410.
Background
Information: The purpose of this item is to approve Change Order No. 1 to the
Illuminated Street Name Sign and Battery Back-up Unit Installation
project (ILSN) to include illuminated street name signs for the
Watermere/Jellico intersection with Southlake Boulevard and the
installation of a traffic signal at the intersection of N. Carroll Avenue
and Federal Way.
City Council awarded the ILSN construction contract to Durable
Specialties, Inc. on February 4, 2014. The signs are currently
being manufactured. Installation will begin upon delivery of the
signs.
TxDOT construction of the Watermere/Jellico at Southlake
Boulevard traffic signal and battery back-up began the week of April
7, 2014. TxDOT's construction contract did not include line items
for the illuminated street name sign. This change order will allow
for the installation of the ILSN concurrently with the remainder of
the Southlake Boulevard corridor.
The design of the Traffic Signal Installation at N. Carroll Avenue
and Federal Way is complete and right of way has been confirmed
for the right turn lane of westbound Federal Way to northbound
Carroll Avenue. The right turn lane and 8-foot sidewalk will be
constructed by th Public Works Street Department prior to
installation of the traffic signal. Manufacturing time of the signal
poles is eighteen to twenty weeks. In order to install the signal prior
to the 2014 "Home for the Holidays" event, this change order with
Durable Specialties, Inc. will expedite the order and manufacturing
of the traffic signal poles and mast arms.
The City Attorney's office has reviewed the request to change order
greater than 25% of the original contract and have offered an
opinion that it is acceptable in this case as it is "necessary to
preserve or protect the public health or safety of the municipality's
residents."
Financial
Considerations: The Traffic Signal Installation at N. Carroll Avenue and Federal
Way project is a City Council approved CIP project funded in FY13
and FY14 from the Red Light Camera Fund. Funding for this
project is available in project account 00008 and the approved
budget is $315,000 for engineering and construction.
The illuminated street name sign and battery back-up change order
line items for the Traffic Signal Installation Southlake Boulevard and
Watermere Drive/Jellico Circle W. project will be paid for out of
project's FY13 City Council approved CIP project account 00009.
Strategic Link: The installation of Illuminated Street Name Signs and Battery Back-
up Systems and the Traffic Signal Installation N. Carroll Avenue
and Federal Way project link to the city's strategy map relative to
focus areas of Infrastructure and Mobility. The project will serve
our customers by achieving the highest standards of safety and
security. It provides travel convenience within the City and region.
The specific corporate objectives that are met by this construction
project are to invest to provide and maintain high quality public
assets.
Citizen Input/
Board Review: N/A
Legal Review: The City Attorney has issued an opinion on the legality of this
change order.
Alternatives: The Council may approve the change order or deny it.
