Authorize Director of Public Works to file Notice of Completion with the Los Angeles County Recorder's office. lJ§J&T41RM Mei, Each year, a number of the City's groundwater wells are rehabilitated to replace worn-out parts and materials and restore efficiency and water production as part of the annual groundwater well maintenance and rehabilitation program. Well No. 16, located on Cecilia Street east of Lakewood Boulevard, is one such well that was in need of rehabilitation to restore pump and motor efficiencies and ensure that the City is able to continue to use this well as a reliable water source. Due to the repair nature of the water work, the project was informally bid on April 29, 2019. On May 28, 2019, a maintenance contract for this project in the amount of $144,232 was awarded to Legend Pump and Well Services, Inc. On June 19, 2019, work commenced and is now complete. The well rehabilitation improvements included test pump installation; redevelopment by pumping and surging; bailing; pump testing; replacement of pump, motor and column pipe; well disinfection; and appurtenant work. During rehabilitation, additional work beyond the original scope of the project resulted in two contract change orders in the total amount of $22,112.50. The added costs were offset by the deletion of other bid items (net decrease in contract quantities was $50,735) resulting in the overall project cost to be within the original amount awarded to Legend Pump and Well Services. The additional work included refurbishing the packing box, changes to the size of the well column pipe, and additional pumping and surging.
