AGENDA ITEM: TMDL Wastewater Compliance Project— Wastewater Treatment Plant #1
Sludge and Odor Control Improvements — Bid No. 101116
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Direct rfi
DATE: July 1, 2011
BACKGROUND: While complying with the TMDL nitrogen regulations, the new biological
nutrient removal process will increase the amount of sludge produced. This will tax the existing
inefficient sludge treatment system to its maximum capability, requiring sludge treatment
upgrades in the near future.
Electrical system and sludge studies determined that by upgrading the existing sludge treatment
system at Wastewater Treatment Plant #1, the City could obtain energy savings while reducing
operations and maintenance costs and potential landfill tipping fees. In addition, providing
mechanical dewatering in an enclosed building will reduce potential odors.
An odor control study determined that odors can be reduced by providing an odor control system
to capture and treat gases from the influent screens as well as the proposed sludge treatment
building.
On December 13, 2010, the Commission authorized J. Collins Engineering Associates QCEA) to
provide design, bidding and construction assistance for Wastewater Treatment Plant #1 Sludge
and Odor Control Improvements. Four Additive Alternates were included in the bid:
• Additive Alternate 1 was to replace a severely cracked concrete pad in the sludge loading
area. DEP has commented during inspections that the concrete needs to be replaced. Staff
was going to include this work in the current year's budget and thought pricing would be
better if bid under the Sludge and Odor Control Project. The City can save a small
amount by having the work done by our annual contractor, so Additive Alternate I is
not recommended.
• Additive Alternate 2 — Construct Electrical Room in Existing Blower Building.
Separating the electrical panels and controls from the motors and blowers in an air
conditioned room will extend the life of the electrical equipment. The new
instrumentation is comprised of very sophisticated electronics that could be susceptible to
excess heat. Additive Alternate 2 is recommended.
• Additive Alternate 3 — Construct new 100 KW genset to replace an old 300 KW genset.
The current treatment plant has three existing gensets. The Sludge and Odor Control
Project will eliminate one existing old genset completely. The other remaining genset will
be oversized, and since it is an older genset from the original plant, it will need to be
replaced in the next several years anyway. However, the old generator is still operable
and there is not an immediate need for replacement. Additive Alternate 3 is not
recommended.

JULY 11, 2011
Additive Alternate 4 — Prepare existing blowers and genset for salvage. This item
requests the contractors to transfer the fuel and disconnect/safe -up the one genset and 5
blowers that will be eliminated by the project. This is also a safety item. Additive
Alternate 4 is recommended.
Plans and specifications were completed, bids advertised and 11 contractors were invited to bid.
Four contractors prequalified for the project, and three contractors attended the mandatory Pre -
Bid Meeting. Two contractors submitted bids as follows:
BUDGET: Because bids for the TMDL project came in well below budget, and the $469,000
of additional plant improvements were rolled into the final design, a total of $2.53 million is
available in the Sewer Fund for this project, under account number 410 - 5508 -535 -6300. Funding
will be through the DEP State Revolving Fund loan program at reduced interest rates.
RECOMMENDATION: Award the contract for Wastewater Treatment Plant #1 Sludge and
Odor Control Improvements, Bid No. 1011 -16 to WPC Industrial Contractors, LLC. Include in
the award, the Lump Sum Base Bid in the amount of $2,157,000 plus Additive Alternates 2 and 4
for a total amount of $2,194,500. Authorize the City Manager to sign the contract. Authorize staff
to encumber $215,700 under a separate purchase order for use as a contingency for the project.
ATTACHMENTS: 1. Bid Tabulation for Bid 1011 -16.
2. Bid Analysis for Bid 1011 -16.
3. Recommendation for Award from JCEA.
