AGENDA TTEM: Replacement of Force Main from Lift Station B
Bid No. 0102-17
SUBMITTED BY: Donna I{aluzniak, CEP, Utility Duecto~ ytd/ /
DATE: June 14, 2002
BACKGROUND: One oftbe recommendations of the Sewer Master Plan was to
replace the existing 10-inch diameter force main from Lift Station B (425 l lm St.) with a
new 12-inch force main. This force main carries wastewater from Lift Station A (460
Palm Ave.) and Lift Station B to Wastewater Treatment Plant No. 1 (1100 Sandpiper
Lane), and the size of this force main was determined to be restrictive, a contributing
factor to sanitary sewer overflows during heavy rainfalls.
The force main is located in an easement running through the Selva Lakes subdivision,
aad residents have buih improvements over the easement, making access very difficuh.
Aikenhead & Odom designed the replacement force main, specifying trenchless
technology be used within the easemern to avoid disturbing the area. Staffprepared bid
documents.
Bids were advertised, and seven invitations were sent to bidders. Two bidders submitted
prequalification packages, and only one bidder, Gruhn May, Inc., submitted all required
documentation to prequalify. A mandatory pre-bid meeting was held on May 23, 2002,
and a single bid was received on June 5, 2002. Gruhn May, Inc. submitted prices for two
alternate methods of construction, as well as a bid with modified quantities to eliminate
extraneous fittings:

Total Base Bid $385,434.92 $301 829.92 $282,635.50
BUDGET: .Budget for this project was $130,000, based on the rough estimate
provided in the Sewer Master Plan. Adcenhead and Odom's determination of probable
costs after design completion was $179,000. High prices from subcontractors, costs of
bypassing lift station flow during construction, and difficuh roadway crossings accounted
for the high amourn of the bid. If other contractors or subcontractors become interested
in bidding, it may be possible to obtain better prices.
