The additional technical support is anticipated to include but is not limited to providing additional risk mitigation measures, detailed electrical and instrumentation design, isometric piping layout drawings, addition of blower and ventilation system and construction phase technical support. OUTLINE OF SCOPE OF WORK UNDER TASK AUTHORIZATION NO. 26 At the O.N. Stevens Water Treatment Plant, pressurized liquid chlorine is piped from the railcar storage area to the gas measurement building where it is first converted to gas at the evaporators,and then metered at the chlorinators prior to injection. A portion of the liquid piping between the railcars and the exterior wall of the gas measurement building was replaced in the past few years and is still in good condition. However, the piping from the exterior of the building to the feed side of the three evaporators is in very poor condition and needs to be replaced. The purpose of this task authorization is to assist the City in the replacement of the liquid chlorine piping that runs between the outside wall of the gas measurement building and the upstream side of the three evaporators (the portion in poor condition). This task authorization will provide the City with recommendations for replacement of the piping along with the development of a construction package for implementing the recommendations. Additionally, due to the critical nature of the project, this task authorization will also assist the City by providing extensive construction phase services support for the successful replacement of the piping. OUTLINE OF SCOPE OF WORK UNDER SUPPLEMENTAL TASK AUTHORIZATION NO. 26B The notice to proceed for Task Authorization No. 26 was received on April 24, 2018. The project is currently in the design phase and during this phase, additional items were identified by the City staff that are to be included in the scope of work to ensure successful completion of this critical project. This task authorization is proposed as a zero dollar task authorization to address the additional design effort.These additions in design include the following: Task Order No. 26B Exhibit"A" Page 2 of 8 • • Development of isometric drawings, • Development of electrical drawings, • Replacement of a section of chlorine gas piping • Replacement of the existing ventilation system(blower and louver assembly) Apart from revisions to plans and specifications;supplementary site visits,meetings and coordination were required to include the additional design elements in the bid package. In order to ensure successful construction/installation of the additional design elements, this task authorization also proposes to include additional effort for Engineer to perform necessary construction observation services. It is also to be noted that the intent of the design performed under this task authorization was to address the high risk and functionality issues associated with the existing system. The intent of the emergency piping and ventilation system replacement was not to redesign the existing system to meet current codes, but to address system issues by replacing the existing components with similar components. The improvements are anticipated to be in service until the proposed replacement of the system within the next 3-4 years. Proposed improvements have been selected in collaboration with the City to meet their operating needs while the system remains in service. SCOPE OF WORK BASIC SERVICES: The Engineer will perform the following: Task 0001 —Design Phase 1. Develop isometric drawings for the proposed liquid chlorine piping system as requested by City staff. 2. Perform up to two(2)additional site visits to assist in design. 3. Develop additional details and specifications for the replacement of a section of chlorine gas discharge piping identified to be in critical condition. 4. Perform sizing calculations and include notes in drawings specifying make and model of new blower and louver system for the gas measurement building. 5. Specify electrical requirements and connections for proposed blower. 6. Develop additional plan sheets for electrical power plan, conduit and wiring schedule. 7. Provide additional draft bid package submittal to City and conduct submittal workshop to obtain City review comments on revisions/additions made to original draft bid package. Task 0003—Construction Phase 1. Perform up to two (2) additional site visits to observe construction/installation of additional design items. 2. Provide clarifications and respond to RFIs from the contractor. Task Order No. 26B Exhibit"A" Page 3 of 8 • DELIVERABLES The Engineer will prepare final bid package and provide one(1)hard copy and one(1)electronic copy to the designated City Task Authorization Manager specified under this task authorization. The final bid package will include the following: • Construction plans • Technical specifications • Maintenance of Operations Plan • The Chlorine Institute Pamphlet 6-Edition 10-Piping Systems for Chlorine • City of Corpus Christi ONSWTP Instrumentation and Electrical Standards(E13064) SCHEDULE The Engineer's services shall be performed in a timely manner consistent with sound professional practices. The Engineer will complete the work according to the following schedule: Activity Completion Date Contract Execution-Notice to Proceed(NTP) TBD Task 0001—Design Phase • DRAFT Submittal Workshop II August 29,2018 • City review comments on DRAFT bid TBD package submittal II • FINAL Bid Package 2 weeks after receipt of comments Task 0003—Construction Phase TBD based on Contractor's Schedule The time limits set forth in the schedule shall include allowances for reasonable and expected review time by the City and approval by authorities having jurisdiction over this project and shall not be allowed as cause for delay or adjustments to the schedule. Delays caused by review times by the City exceeding those anticipated by the Engineer's schedule are cause for adjustments in the schedule. Any adjustments made to the agreed upon schedule shall be made in writing and accepted by both parties. The Engineer shall begin work immediately upon receipt of the executed Task Authorization and/or Notice to Proceed(written or emailed). FEE This is a zero-dollar task authorization that re-allocates previously approved funds.It reduces the total NTE amount of TA 23-Task0002 by$31,426.05 and increases NTE amount for TA26 by$31,344.
