Item 4E CITY OF
SOUTH LAKE Item 4E
MEMORANDUM
(December 6, 2016)
To: Shana Yelverton, City Manager
From: Rob Cohen, Public Works Director
Subject: Approve Change Order No. 8 with Wilson Contractor Services,
LLC for the Water and Sanitary Sewer Relocation Project for
FM 1938 in the amount not to exceed $140,000
Action
Requested: Approve Change Order No. 8 with Wilson Contractor Services, LLC
for the Water and Sanitary Sewer Relocation Project for FM 1938 in
the amount not to exceed $140,000.
Background
Information: Change Order No. 8 in the amount of $140,000 is for additional
work required to install the remaining 8-inch water line along the
FM 1938 corridor within the City of Keller. This segment of water
line was scheduled to be completed by Wilson Contractor Services,
LLC (WCC) in conjunction with TxDOT during the construction of
the roadway widening project due to the amount of needed
excavation. The trench in which the water line was placed required
flowable backfill in lieu of compacted select fill due to the proximity
of a retaining wall footing. This change order also includes
additional work requested by the City of Keller to extend an 8-inch
water line an additional 662 feet to the north. A retaining wall was
added to the roadway project in the vicinity of this water line making
it difficult to extend the water line after the completion of the
roadway project. This water line extension is needed for the
purpose of providing fire protection to this area of the City. The City
of Keller will reimburse the City of Southlake as outlined in the
Interlocal Agreement executed on July 17, 2013.
The FM 1938 Phase II Roadway Widening Project from FM 1709 to
the Randol Mill Bend required relocation of water and sanitary
sewer. The Texas Department of Transportation (TxDOT) requires
public infrastructure owned by the cities be relocated from
underneath future pavement to the parkways. Wilson Contractor
Services, LLC was awarded the contract to relocate these utilities.
City Council awarded the construction contract to Wilson Contractor
Services, LLC on August 20, 2013 in the amount of $1 ,845,378.
These eight (8) change orders, totaling $598,594, have increased
the contract amount to $2,443,972. The water and sanitary sewer
Item 4E
relocations within the City of Southlake were completed in
December 2014.
