AGENDA ITEM: Change Order No.3 for Bid 1011 -01
Sludge Air Flow Control Valve /Air Flow Meter and Aeration Tank Wall
Valves
SUBMI'T'TED BY: Donna Kaluzniak, CEP, Utility Director
DATE: September 6, 2011
BACKGROUND: As part of the TMDL WWTP #1 improvements, the nine existing large
blowers will be replaced with 4 new blowers that are much more energy efficient. In this TMDL
Project, the manufacturer (Siemens) is providing all equipment associated with delivering
aeration to the modified aeration basins. They are the supplier of the new high efficiency
blowers, Master Control Panel, air valves and air meters as well as the complete control system.
Siemens has the "sole source responsibility" to provide the equipment as well as the control of
this critical equipment.
Under the TMDL scope of work, the manufacturer already had included in their fee, the cost of
programming of the new air blowers for the new sludge improvements. Since the Sludge & Odor
Control Project was not designed at the time of bid and would be bid to General Contractors, the
best solution to ensure "sole source responsibility" was to complete the sludge design to
determine required equipment and purchase the required air flow meters and valves under WPC's
original TMDL contract as a change order.
The cost of the valve with controls is $13,039.85.
In addition, staff requested the contractor to provide a cost for additional valves between the
baffle walls in the aeration tanks, which will allow for less costly maintenance of the tank in the
future by reducing the need for pump and crane rental when the tanks need dewatering. The Cost
of the additional valves is $13,392.79.
There is a delay for some of the critical equipment (mixers) for the TMDL WWTP #1 project
that will affect the overall completion schedule. (More information on equipment delays is
discussed in the staff report for Change Order No. 1 for the Sludge and Odor Control Project).
The contractor has requested an additional 60 days for completion. This is a time -only change
order — no cost increase.
BUDGET: Funds for the Change Order No. 3 are already encumbered as part of WPC's
contract, which included a contingency of $238,140.
