BUTIER coml,"110" M4,"Mets. cenralld,q Cnow"m Casey Harris Principal -In. -Charge / Senior Schedulerl Claims Station Project. Phase 2 consisted of the constructor of a new 10,000 SF storm water pump station that uses four conventional vertical turbine pumps Installed in a circular wet well. The pump station also consists of new mechanical, electrical, and control systems. An intake pipe was Installed on the slope of the embankment, connecting the new pumps to the Intake Invert. Senior Scheduller, Chino 11 Desaller Concentrate Reduction Facility; Jurupa Valley, CA; Chino Basin Desalter Authority (Completion: 2016— Value: $46.6 mililon)—Senior Scheduler for the CRF groundwater treatment facility. Both !on exchange (IX) and RO treatment trains are used to treat brackish groundwater from eight wells that also have elevated nitrate concentrations. The project scope included construction of new softening, clarification, filtration, and secondary RO (SRO) treatment and solids dewatering and storage; Installation of a new decarbonator; installation of a new transfer pump with motor with associated VFD and motor controls and discharge piping and valves', installation of new cartridge filters; modification of the existing sulfuric acid chemical system; modification of the existing threshold Inhibitor chemical system; and site modifications, Including fencing and gates, yard piping, and storm drain replacement. Senior Scheduler, Carlsbad 50 MGD Seawater Reverse Osmosis Desalination Plant and 10-Mile Conveyance Pipeline; Carlsbad, CA; Poseidon Water (Completion: 1212015; Value: $697 million) —Mr. Harris provided scheduling services for the new construction of a 50 MGD seawater reverse osmosis deselination plant at the EncIna Power Station located in Carlsbad, CA. The scope also included the construction of a 2.5 million gallon product water storage tank; product pump station; and conveyance pipeline to daliver the drinking water produced by the Project to water utilities and municipalities in San Diego County. The 10-mile. 54-inch diameter pipeline was constructed under Interstate 5 Highway and a railroad using a jack and bore tunnel method, Butier staff coordinated closely with the City of Carlsbad, SDCWA, SDG&E, Poseidon and the Coastal Commission during the construction of the tunnel option across Macario Canyon. The pipeline alignment includes over 6,000 feet of tunnels performed by four dIfferent tunneling subcontractors. One of the tunnels is over 1,700 linear feet, 30 feet below sea level, and required a vertical shaft over 80 feet In height, Senior Scheduller/Risk Analysis, Groundwater Reliability Improvement Program (GRIP) Advanced Water Treatment Facility Project, Water Replenishment District of Southern California (Value: $100 million) —Mr. Harris is providing scheduling and risk analysis services as a part of GHD's Owner's Agent/Owner's Engineer team for the GRIP Advianced Water Treatment Facility Project. As a part of the GRIP Program, an advmnced water treatment facility is being constructed to purify 10,000 acre feet (3.25 billion gallons) of tertiary treated (recycled) water annually, The GRIP AWTF is being built on a 5.2 acre property in the City of Pico Rivera, adjacent to the San Gabriel River. The GRIP AWTF will include the following treatment processes: autornatic strainer; microfiltration (MF) and reverse osmosis (RO) followed by Ultraviolet advanc9d oxidation (UVAO),, cartridge fitrntion: decarbonation; and pH adjustment/corrosivity stabilization.
