CITY COMMISSION MEETING
AGENDA ITEM: Award of Additive Alternate No. 1 and Change Order No. 1
for Bid 10 11 -0 1 — Blower and Electrical Motor Control Center
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Directo
DATE: February 18, 2011
BACKGROUND: On December 13, 2010, the City Commission awarded the contract for
Bid No. 10 11 -0 1 Wastewater Treatment Plant #1 Improvements to WPC Industrial Contractors,
LLC. At that time, staff recommended deferring Additive Alternate No. 1— Blower to allow for
further review and possible implementation of sludge /odor control improvements.
As part of the TMDL WWTP #1 improvements, the nine existing large blowers will be replaced
with 3 new blowers (under the previously approved Base Bid) that are much more energy
efficient. Additive Alternate No. 1 - Blower will allow for redundancy during maintenance or
repairs, while providing the more energy efficient blower for existing sludge treatment as well as
sludge improvements currently under design. The contractor needs to proceed with ordering the
blowers in order to stay on schedule, and to maintain the vendor pricing reflected in the bid.
Staff is also requesting Change Order No. 1 to allow for purchase and installation of the
electrical Motor Control Center (MCC) for the additional blower at this time. Originally, staff
planned to include the electrical MCC panel installation at the time of the sludge and odor
control improvements. However, since the contractor will be installing 3 other similar identical
MCC panels as part of the current project, the City would save a considerable amount of money
by doing the work now. The base price for the MCC under current contract (no installation) is
approximately $17,500 and to purchase on a separate stand alone construction project would be
$55,900 (equipment only - no installation. The savings is over $38,000 - see Attached quote). In
addition, the City can begin to use the high efficiency blowers (instead of the older blowers)
much sooner since the sludge facilities are scheduled for bidding separately.
BUDGET: The bid price for Additive Alternate #1— Additional blower was $129,000. The cost
for Change Order No. 1 for the purchase and installation of the new blower MCC is $29,440.
Funds for Additive Alternate #1 are available in the Sewer Fund under account number 410-
5508 -535 -6300, as Bid No. 1011 -01 came in well under budget. Funds for the Change Order No.
1 are included in the contingency that was already awarded as part of the original contract.
RECOMMENDATION: Award Additive Alternate No. 1— Blower to WPC Industrial
Contractors, LLC in the amount of $129,000 per Bid No. 1011 -01. Approve Change Order No. 1
for Electrical Control Panel Installation for the blower in the amount of $29,440 for Bid No.
1011 -01. Authorize the City Manager to sign Additive Alternate No. 1 and Change Order No. 1.

NEW SLUDGE BLOWER - ADDITIVE ALTERNATE & CHANGE ORDER #1 - PURCHASE &
INSTALL NEW MCC FOR SLUDGE BLOWER
ITEM: Award of Additive Alternate No. 1 and Change Order No. 1
for Bid 10 11 -0 1 — Blower and Electrical Motor Control Center
RECOMMENDED BY: John Collins., PE - J. Collins Engineering Associates, LLC (JCEA)
DATE: February 21, 2011
CHANGES RECOMMENDED:
Additive Alternative #1 (4th high efficiency blower) was a bid item on the project - WWTP #1
improvements for TMDL Compliance. The project was awarded to the lowest bidder (WPC
Industrial Contractors, LLC) on December 13, 2010 and the Additive Alternate (blower) was
deferred until the Sludge Design was implemented. The sludge improvements design started in
January 2011 and the new high efficiency blower is a key component of this system. JCEA is
recommending that Additive Alternate #1 (the new high efficiency blower) be added to the
immediate work of WPC while the pricing is favorable. The City received very favorable vendor
pricing through a Equipment Procurement Program in 2010 to acquire three identical blowers
which are currently in the ongoing work being performed by WPC. The vendor also has
provided the same pricing on the fourth blower (additive alternate). The total bid includes the
new blower and mechanical installation of the new blower on a concrete pad with new air piping
installed. The installed price of the Additive Alternate #1 is $129,000. The budget price of the
equipment only in early 2010 was over $150,000 (no installation).
New Electrical Motor Control Center for 4th High Efficiency Blower (Change Order #1) - The
fourth blower proposed in Additive Alternate #1 is an installed mechanical price. JCEA is
recommending that the new fourth blower be brought into service in the ongoing WWTP#1
Improvements phase by including the electrical service to the new blower. This would include
purchasing, installing and energizing a new Motor Control Center (MCC). JCEA's
recommendation to include the electrical equipment for the new blower is based on the
following:
• City capital savings are considerable. The MCC manufacturer has stated that a price
increase will go into effect by March 2011. Based on the vendors' quote, the equipment -
only price for the MCC under the current contract is approximately $17,500 (same price
as new three MCCs for blowers in current project). To wait and purchase the equipment
later in the year under a separate bid sludge project - the quote is $55,900 (equipment
only - no installation). The potential savings is over $38,000 - see attached quote).
• The City can utilize the high efficiency blowers sooner for the current aeration of the
existing sludge facilities (instead of the older inefficient blowers) since the sludge
facilities are scheduled for bidding separately at a later date.
• Single source responsibility of new equipment - One contractor is responsible to ensure
that all equipment is installed and functioning properly since all four blowers and the
associated electrical, instrumentation and start-up services will be by implemented by
the same Contractor.
• The current WWTP#1 Improvements project has been awarded to WPC with a
Contingency Amount of $238,140. The $29,440 for the electrical work for the fourth
blower would come out of this contingency (no contract increase due to Change
Order#1).
