TASK 1: As-Needed Startup Support Services through 30 June 2008 <br /> The City has requested that Kennedy/Jenks provide ongoing support for startup activities on an <br /> as-needed basis. Activities associated with these support services are anticipated to include <br /> the following: <br /> Up to 8 hours per week of engineering services between 25 February 2008 and 30 June 2008. <br /> Support is anticipated to include the following: <br /> a. Site visits to meet with City staff for review of operational questions and for reviews of <br /> DPS performance. <br /> b. Participation in scheduled meetings with the City regarding DPS operations and <br /> performance. <br /> c. Providing responses to requests for information or research related to DPS operational <br /> questions. <br /> d. Responding to questions or requests for information related to the operation of the <br /> storage tanks, hydropneumatic tank, and stand-by generator. <br /> TASK 2: Engineering Support Services for Warranty Modifications <br /> The City has requested Kennedy/Jenks to provide engineering services related to modifications <br /> that are to be made to the DPS no earlier than 12 April 2008, which is the end date of the 1-year <br /> construction warranty period. Services to be provided by Kennedy/Jenks will address the <br /> warranty items identified during the 1 October 2007 meeting referenced above: <br /> a. DPS Pump Minimum Run Speed/Run Time <br /> b. Distribution box gate control <br /> c. Design criteria and equipment list for SBSA landscape impoundment demand and SBSA <br /> Plant recycled water demand <br /> The City has requested the Kennedy/Jenks conduct the necessary engineering services prior to <br /> the 12 April 2008 date such that implementation of the agreed upon scope can be conducted <br /> immediately following the end of the construction warranty period. Work activities anticipated <br /> for each of the warranty items are provided below: <br /> A. JP/IP Minimum Run Speed/Run Time <br /> Following the 7-day operational test (which was a limited test due to the unavailability of the <br /> distribution system at the time of the test) and following substantial completion of construction, <br /> additional testing of the DPS pumps and controls was conducted to further verify proper <br /> programming and to fine-tune settings. The additional testing was necessary to implement <br /> desired DPS functionality for delivering water to the new distribution system; testing with the <br /> DPS connected to the distribution system had not been possible before this time. As part of the <br /> testing, it was identified that some key elements of the specified control strategy had not been <br /> implemented in the program. <br /> After programming changes were made and system operational parameters were adjusted, it <br /> became apparent that additional overlap of the jockey pump (JP) and intermediate pump (IP) <br /> stages would be necessary from an operational perspective for reliable automatic operation and <br /> more consistent system pressure control. <br /> For operations in automatic operation modes, increasing the pump stage overlap will require a <br /> reduction in minimum pump speeds in the PLC program.
