Item 4HCITY OF
SOUTH LAKE
MEMORANDUM
(October 5, 2010)
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Director of Public Works
Subject: Approve Change Order No. 4 with Circle C Construction in the
amount of $62,551.41 for a 30 -inch water line on T.W. King.
Action
Requested: Approve Change Order No. 4 with Circle C Construction in the
amount of $62,551.41 for a 30 -inch water line on T.W. King.
Background
Information: In March 2009, Circle C Construction began construction on the 30-
inch water line along Florence Road and T.W. King Road. Also
included in the contract was the pavement reconstruction of both
Florence Road and T.W. King Road from Hwy 114 to the T.W.
pump station as well as relocation of a portion of the 12 -inch water
line located along Florence Road.
Change Order No. 1 in the amount of $400 was approved in June
2009 by the City Manager's office. This change order included
eliminating a 12 -inch gate valve and temporary 2 -inch water line
and adding a tapping sleeve and valve which would allow the 12-
inch water line to stay in service while the new water line was
connected to the existing water line.
Change Order No. 2 was approved by the City Manager's office in
December 2009. The change in scope included revising the
original pavement reconstruction design to maintain the current
width of the roadway. Widening the road the additional 2 feet as
proposed in the original plans would have resulted in steeper
borrow ditches along the road which would have not allowed the
property owners to maintain the slopes without greater difficulty.
The original contract was reduced by $152,466.80 dollars with this
change order.
Change Order No. 3 in the amount of $30,007.50 was approved by
the City Manager's office in March 2010. This change order
allowed for asphalt and concrete driveway approach repairs /
adjustment as a result of elevation grade changes.
The project is now complete. Change Order No. 4 reconciles the
bid item quantities to the actual quantities and includes additional
paving quantities, block sod, and driveway repairs.
Financial
Considerations: The original contract amount awarded to Circle C Construction was
$2,635,235. The approved and proposed change orders bring the
revised contract amount to $2,575,727.11. The contract price is
within the original project budget of $2,898,800.00.
