RE: Kaw Water Treatment Plant High Service Pump Replacement Project UT0703KA - Set Bid Date
Please include the following item on the City Commission Agenda
for consideration at the February 12, 2008 meeting.
Authorize the City
Manager to set a Bid Date of March 18, 2008 for the Kaw Water Treatment Plant
High Service Pump Replacement Project UT0703KA.
Project History:
The 2003 Water System Master Plan identified a 2008 Capital
Improvement Project to replace the three (3) existing West Hills Service Area
high service pumps at the Kaw Water Treatment Plant. The Master Plan also
identified a future project for the replacement of the four (4) existing
Central Service Area high service pumps at the Kaw Water Treatment Plant. Both
of these improvements were proposed to meet increased demands, improve
reliability and reduce maintenance activities associated with the older 1954 pumps.
Operational data also indicates that these pumps no longer pump at their rated
capacities, most likely due to wear of the impellers and bowls over the years.
On March 16, 2004 the City Commission awarded a contract
for the replacement of one (1) of the West Hills Service Area high service
pumps. This replacement was necessitated by the failure of the upper pump
casing in 2003. This pump is not one of those proposed to be replaced under the
current project but it is an example of the failures incurred by and the
maintenance required for the existing 1954 pumps.
Project Timeline:
May 2007: City approved a Purchase Order for $2,500.00 with Black
& Veatch for Engineering Services related to the delivery of Technical
Specifications required for bidding the replacement of another failing high
service pump. Black & Veatch was selected for this work based on their work
to provide similar documents for the previous 2004 West Hills Service Area high
service pump replacement. Department Staff will assemble the front end contract
documents and combine these with Black & Veatch’s technical specifications
for bidding.
November 2007: Department Staff propose expanding the scope of the
project to include the replacement of all the Kaw Water Treatment Plant high
service pumps not previously replaced in 2004. Staff recommended the expanded
scope based on the diminished pumping capacity, expanded maintenance requirements
and reduced reliability of the existing pumps. As noted earlier the existing
pumps were installed in 1954. The Purchase Order with Black & Veatch was
increased to a total of $14,500.00 to cover the expanded scope and includes
Engineering services during the pump installation. Department Staff have
included the costs associated with the expanded scope in the 2008 Rate Plan.
Project Status: Black & Veatch and
Department Staff have finalized the bidding documents and the project is ready
to be advertised for bidding.
The project is scheduled to be substantially complete in December
2008. The project cost is estimated to be $350,000.00.
Project Funding.
Funding for the project will come from the Utility Department Capital
Improvement Project non-bonded construction fund.
Action Request. Authorize the City Manager to set a Bid Date of March 18, 2008 for
the Kaw Water Treatment Plant High Service Pump Replacement Project UT0703KA.
