Portable By-Pass Pump - Main Island PS Project
Okaloosa County, Florida - Bid No. WS 02-13
Dear Mr. Littrell:
Material ONLY bids were received and opened for the "Main Island Trailer
Mounted By-Pass Pump Unit” on November 15, 2012. The Board of County
Commissioners received six (6) responsive bids for the project.
The project was bid with a Total Base Bid and one (1) Optional Cost Item. The Total
Base Bid was for a complete diesel driven sewage by-pass pump, sounded
attenuated enclosure, control panel with electronic start and stop and monitoring,
tandem axel trailer with embedded fuel reservoir, and 12” inlet/outlet connection
fittings.
The Optional Cost Items:
ITEM 2 Compressor Assisted Priming System (Deductive)
Enclosed is a comparison spreadsheet of the equipment criteria specified and what
was provided by each bidder. It also includes bid tab results and the estimated
delivery time for each. National Pump and Compressor had the lowest base bid and
second lowest delivery time. Thompson Pump (specified manufacture) was the
second lowest bidder and had the lowest delivery days. Constantine compared the
information provided by National Pump and Compressor against the requirements
specified and determined the following:
e Pioneer Pump Model# SAPP1212S17L72 does not equal the specified Thompson
Pump 12JSVG-DJDS-90H hydraulic performance curve.
e Pump cannot produce required 5100 GPM flow at 160 TDH. (5200 gpm @ 116’)
¢ Pump does not meet minimum shut-off head of 365 feet. (192)
