this project:
TOTAL BID AMOUNT
116,650.00
119,505.00
128,670.00
129,525.00
136,450.00
140,000.00
142,140.00
143,970.00
147,537.45
155,130.00
169,902.70
219,455.00
"Corrected bid amount
The low total bid amount is 33 percent below the Engineer's Estimate of $175,000.
When questioned, the Contractor stated the lower price was a result of the recession
and a very competitive marketplace. The low bidder, Brongo Construction, possesses
the General "A" contractor's license as required by the project specifications. Brongo
has satisfactorily completed similar water line projects for several school districts and
private developers. Their reference check revealed very favorable comments. The
Contractor was a low bidder on the Newport Heights sewer main replacement project in
1995 and completed the job to the City's satisfaction.

PROJECT DESCRIPTION:
On October 8, 2000, a leak was detected in the University Drive 20 -inch transmission
main (located in the eastbound bike lane of University Drive near Bonita Creek Park).
During the repair, it appeared that due to poor installation and insufficient protective
coatings, corrosion of this 15 -year old ductile iron pipe had occurred at the joint. One
section of the joint showed cracks that appeared to have been created during the
original construction. A section of the ductile iron pipe was removed and replaced with
a 20 -inch PVC pipe. The Ductile Iron Pipe Research Institute was called to analyze the
failure and they cited poor installation and highly corrosive bay soils as the cause of the
failure.
The transmission main began to leak again in March 2061, at a different location but
very close to the original failure. Similar joint corrosion was identified as the cause.
The pipe appeared to be in extremely poor condition and replacement was
recommended.
Project funds are available in the Water Transmission Main Replacement Capital
Improvement Account, 7501- C5500386. The project should take about two months to
complete after award. Minimal traffic disruption will occur with only one lane of traffic
being impacted.
