necessary to complete the project swiftly,the May 2012 emergency resolution also established a limited competitive process for the selection of a contractor to replace the approximately 1600 feet of discharge line. Under that process,four contractors submitted bids on June 5, 2012. On June 6, 2012, City Council awarded the contract to Shoreline Construction,the low bidder in the amount of $896,914.50,which was significantly lower than the other three bids,which were approximately$1.4 million to$1.5 million. G. As Shoreline Construction began work,the Public Works Department continued its analysis of the condition of the discharge line. By late July and August 2012,the pipe thickness readings made it apparent that severe erosion and pitting persisted along at least the first 3000 feet of the discharge line. There were readings at or below 0.1 inch,which is less than 25%of the standard pipe thickness of 0.39 inch for such a pipeline. Prior to receiving this data, it was unforeseen that the severe erosion and pitting would extend beyond the first 1600 feet of the discharge line. Based on these new findings,the Public Works Department has concluded that the entire 5000 feet of discharge line, not just 1600 feet, must be replaced as soon as possible. This new information also caused the Public Works Department to conclude that a new route for the discharge line is necessary. H. In accordance with the May 2012 emergency resolution,the City has directed Shoreline Construction to proceed with the replacement of first 2000 feet of the discharge line in the new route. The Mayor has executed a change order in the amount of$219,372.30, including sales tax for this work. This work is underway. Because of the imminent threat of possible future breaks and the possible damage to property and disruption of critical service, immediate action is necessary to replace the remaining approximately 3000 feet of the discharge line. The Public Works Department is proceeding as fast as possible with the survey,design, and permitting of replacement the 3000 ft of discharge line. J. Because of the imminent threat and the need for immediate action, an emergency exists. Time is of the essence in proceeding with the replacement of the remaining approximately 3000 feet of discharge line. The Public Works Department believes that the fastest method of replacement is not to wait for completion of entire design of the remaining discharge line. The replacement discharge line will be designed in segments. Once the designer completes design of a segment,that segment design will be given to the contractor for construction of that segment. The designer will stay about one segment ahead of the contractor until the entire discharge line is replaced. K. The Public Works Department has analyzed the possible methods for procuring a contractor for the replacement of the remaining 3000 feet of discharge line. The Public Works Department believes that completing the replacement of the discharge line by negotiated change order to the Shoreline Construction contract will save between four to eight weeks in comparison to a limited emergency competitive process as done in May 2012 or in comparison to a normal competitive process. Because of the deteriorated nature of the discharge line, it is the professional engineering opinion of the Public Works Department, including its Director and Engineering Superintendent,that a four to eight week delay of the replacement of the 3000 feet of discharge line represents an imminent and
