Box 9277 Corpus Christi,TX 78469-9277 Re: AMENDMENT NO.5 TO PROFESSIONAL SERVICES CONTRACT BROADWAY WWTP EFFLUENT LINE REHABILITATION (CITY PROJECT NO. E10003) Dear Mr. Edmonds: With regard to the services associated with Project E10003- Broadway WWTP Effluent Line Rehabilitation,we are proposing the following $0.00 amendment to provide technical support for the project as requested by the City. PROJECT BACKGROUND The Broadway Effluent Line Rehabilitation Project (E10003) original contract was executed in 2009. The purpose of the project was initially to rehabilitate approximately 1,450 feet of the existing 42-inch effluent line from the New Broadway Wastewater treatment Plant (NBWWTP) to the concrete lined Salt Flats Ditch, constructing a new outfall structure and connecting to the New Broadway WWTP. In 2011, a new Amendment was executed that included rehabilitation of approximately 1,300 linear feet of existing 42-inch concrete flex joint effluent line and the installation of approximately 2,600 linear feet of new 42-inch line parallel to the Salt Flats Drainage Ditch from the New Broadway Wastewater Treatment Plant(NBWWTP) to the Port of Corpus Christi ship channel. However, due to issues arising in obtaining the necessary discharge permits from TCEQ concerning the line rehabilitation and outfall structure relocation,the project was put on-hold by the City. In July 2015 and 2016, the City and LNV explored a number of options for the rehabilitation of the 42-inch effluent line. LNV was contacted to provide engineering services to redesign the NBWWTP Effluent Line Rehabilitation project, which included slip lining approximately 1,300 linear feet of the existing 42 inch effluent line and the installation of approximately 2,600 linear feet of a new 42 inch line from the New Broadway WWTP to the Port of Corpus Christi Ship Channel. LNV submitted the design for this project to the City on September 16, 2016 but the construction of the project was put on-hold until further notice. Page 1 of 4 EXHIBIT A . . . LNV engineers architects surveyors Following this, in September 2017, LNV was contacted by the City to assess damage to the 42- inch effluent line located approximately 300 feet north of the permitted outfall structure at Corpus Christi Ship Channel. Based on the assessment, LNV assisted the City with the design for the rehabilitation of the 42-inch reinforced concrete effluent line from New Broadway Wastewater Treatment Plant (NBWWTP). As per original design, 1,350 LF of the 42-inch effluent line from NBWWTP was to be rehabilitated by slip lining the existing pipe from Junction Box B to the outtake at Salt Flats Ditch. As per the City's directive, it was decided that the effluent line would be rehabilitated by CIPP lining instead of slip lining and construction on the project began in March 2018 and was completed in April 2018. PURPOSE At present, due to LNV's long-standing association with the project and familiarity with project components and constraints, the City has requested additional technical support for analysis of data from between 2009-2015 along with the submission of a report to United States Army Corps of Engineers (USACE) reporting the completion of construction. In addition, LNV is to also provide technical and supplemental support to the City as requested. SCOPE OF SERVICES: ADDITIONAL SERVICES: ITEM 8—Technical and Supplemental Support This task will be comprised of the following: • Provide the City with record drawings and base maps from 2009-2012 showing the location of the effluent line. • Provide the City with relevant construction plans, as-builts, easement information, correspondence, etc. from LNV's association with the Port of Corpus Christi Authority (POCCA)during the earlier design phase of the project. • Prepare a report for the USACE detailing the work performed during Amendment 3 and 4 of this project and stating that all efforts have been completed as per requirements. • Provide CCTV data for work done on 42-inch Broadway WWTP effluent line in the past and assist in evaluation of videos. • Provide the City with additional technical and supplemental support as requested.
