INDEXED City Project No. E16264 Professional Services Contract City of Corpus Christi Water/Wastewater Treatment On-Call Support Task Authorization No. 31—Ship Channel Waterline Crossing at Cantwell Ln Evaluation June 19, 2018 LIMA, EXHIBIT A Penn 4 of 7 8. LNV Ay SCOPE OF WORK Project No. E16264 Water and Wastewater Treatment On-Call Support Task Authorization No.31— Ship Channel Waterline Crossing at Cantwell Ln Evaluation PURPOSE The U.S. Army Engineering District, Galveston (USAED), will soon commence construction of the deepening and widening of the Corpus Christi Ship Channel,located in Corpus Christi Bay.The City's water system currently consists of two locations where waterlines cross the Corpus Christi Ship Channel. One location consists of twin 12-inch waterlines crossing parallel to and just east of the existing Harbor Bridge. A second location is at Cantwell Lane and consists of twin 16-inch waterlines. It is believed that the Cantwell crossing was installed at a depth that will conflict with the deepening of the channel and as a result, the USA ED has requested the City of Corpus Christi to remove the 16-in waterlines.These lines are depicted in Attachment B. The purpose of previously executed Task Authorization 30 was to provide technical assistance to the City staff in modeling different scenarios to determine the effects of removal of the 16-inch lines on the distribution system, particularly in the North Beach area. This Task Authorization is an extension of the scope provided under Task Authorization 30. Under this task authorization, the modeling results for the 16- inch waterlines will be evaluated from both a capacity and water quality perspective to determine the number, size, and location of the proposed replacement pipe(s) for the Cantwell Crossing waterlines. The benefits of replacement and relocation of the waterline will be evaluated from both the City's and the Port of Corpus Christi's perspective. Based on the evaluation, a recommendation will be provided to the City regarding the pipe replacement. In addition,the Engineer's opinion of probable construction costs(OPCC)and a schedule will be provided for the demolition of the existing pipes and construction of the new replacement pipe(s).This task authorization will also assist in coordination with the Port of Corpus Christi Authority (PCCA) and preparing relevant documentation/presentations for meetings with City Staff/City Council on the project.
