Subject: University Drive Zone III 16 -Inch Water Main Improvement Project —Award of Contract No. 3468 February 12, 2002 Page: 2 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. Respectfully submitted PUBLIC WORKS DEPARTMENT Stephen G. Badum, Director 2M MicKael J. Sinacori, P.E.
