Director of Capital Programs City of Corpus Christi P.O. Box 9277 Corpus Christi, Texas 78469-9277 RE: AMENDMENT NO. 5 TO PROFESSIONAL SERVICES CONTRACT Elevated Water Storage Tanks - Citywide (ACR Implementation Phase 2) City Project#8651 Mr. Edmonds: In response to the City's request, we are proposing Amendment No. 5 to account for additional services as a result of water analyzer and fiber optics conduit changes during construction of the Elevated Water Storage Tanks - Citywide (ACR Implementation Phase 2) project. Additional effort is also anticipated for the start-up services phase to provide assistance to the City in bringing the Holly EST and Rand Morgan EST on-line in an efficient manner, without effecting water distribution system operations significantly. PROJECT BACKGROUND As per the user requirements for project #8651 - Elevated Water Storage Tanks- Citywide (ACR Implementation Phase 2), LNV and the City staff agreed to incorporate reagentless analyzers (Hach "CLT10" and Rosemount "Total Ammonia") at both Holly and Rand Morgan ESTs for measuring pH, temperature, total chlorine, monochloramine, and free ammonia. These water analyzers were agreed to by all parties and approved by the City during the design phase of the project. During construction, LNV received a request from the City requiring a change in analyzers. The City requested that instead of the originally proposed reagentless analyzers, reagent analyzers be installed at Holly and Rand Morgan ESTs. It was noted that these reagent analyzers would also require sewer connections in order to safely discharge the reagents. The sewer connections were not a part of the original design at both the sites since reagentless analyzers were initially intended to be used. In addition to these analyzer changes, the City requested that LNV revise the site plans for both Holly EST and Rand Morgan EST to include extension of proposed fiber optic conduits from each tank to existing fiber optic lines so that CB&I could install while mobilized at the site and City MIS Page 1 of 6 801 NAVIGATION I SUITE 300 I CORPUS CHRISTI,TEXAS 78408 OFFICE 361.883.1984 I FAX 361.883.1986 I WWW.LNVINC.COM EXHIBIT A • would not have to contract out the work. During the design phase, upon agreement with the City, only stub outs had been provided at both tanks. At the City's request, the plans have to be modified to include extended conduits and tie-ins. This amendment also proposes additional work to be performed under the start-up services phase. The two (2) new ESTs being constructed under this project (Holly EST and Rand Morgan EST) are to replace the four (4) existing ESTs within Pressure Zone 1 of the City's distribution system and raise the system hydraulic grade line (HGL) by approximately 46 feet (or 20 psi). As a result of the proposed HGL being higher than the existing HGL, it has been deemed necessary to establish a plan in advance that will assist the City in filling new ESTs during the tank disinfection period. The plan is to also include directions to assist City staff in bringing the two (2) new ESTs online and enabling the smooth transition from the existing to the new ESTs. The amendment further provides scope for the Engineer to extend additional technical support to the City during start-up to assist with any unanticipated problems or concerns. PURPOSE OF AMENDMENT NO. 5 The purpose of the work to be performed under this Amendment No.5 is to assist the City with the design revisions and coordination necessary to accommodate the City's request concerning change in analyzer and extension of fiber optic cables at both Holly and Rand Morgan EST, during construction. Additionally, the amendment is to assist the City in transitioning from the existing ESTs to the new ESTs without effecting water distribution system operations significantly. SCOPE OF WORK BASIC SERVICES (N/A) ADDITIONAL SERVICES: TASK 6-D: Start-Up Services for EST-ACR, Phase 2 (#8651) This task is to include the following action items: 1. Assess options and provide City recommended plan for filling new Rand Morgan and Holly ESTs.
