Memo Resolution Aviation Heights Water Line - Phase IIIAgenda No. 6
CITY COUNCIL MEMORANDUM /RESOLUTION
City Council Meeting: November 9, 2010
Department: Engineering
Subject: Contract # 10- PW- 25 -C -04- Aviation Heights
Water Line — Phase III
BACKGROUND
The City annually allocates funding for upgrading the water system in the older part of Schertz.
The 2009 -2010 project was bid on July 15, 2010 with eleven contractors submitting. The low
bidder was RTM Construction Co., LTD with a base bid of $229,739.75. Council awarded the
contract on August 27, 2010.
The Engineer's estimate was $350,426.50.
Funds remaining in the 2009 -2010 budget line item encumbered to 2010 -2001 amount to
$135,260.25. By amending the contract and extending the scope of work using these available
funds, an additional distribution line can be replaced now rather than in the future. Amending the
contract will save approximately $15,000 in costs associated with bidding the work.
FISCAL IMPACT
Budgeted in 2009 -2010 Water Operating Account (encumbered in 2010- 2011): $ 400,000.00
Current Estimated total cost, including engineering, construction and incidentals: $ 264,739.75
Amendment, including engineering, construction and incidentals: $ 94,674.50
Additional engineering: $ 7,000.00
Under budget: $ 33,585.75
RECOMMENDATION
The City Engineer recommends that Council approve an amendment to the contract Aviation
Heights Water Line — Phase III Project awarded to RTM Construction Co., LTD in the
amount of $97,674.50. The amended contract amount will be $324,414.25.
