Project Engineer. Provided plans and <br />construction phase services for approximately 200 feet of existing Years of Experience: <br />36-inch CML&C steel pipe. The relocated pipe was relocated above 19 <br />ground and spans an existing drainage channel with about six to Years with Tetra Tech: <br />several feet of clearance (from the bottom of the channel). Concrete 19 <br />thrust blocks, encasements were required on the vertical riser at both <br />ends of the relocation to handle the corresponding thrust. The above ground pipe was incased within a <br />steel casing for added security. <br />Pipeline from Baker Pump Station to OC-76, El Toro Water District, Lake Forest, CA. 2017. <br />Project Engineer. Design of 5,100 feet of pipeline to minimize the pressure increase within the R-6 <br />Pressure Zone as a result of the Baker Pump Station. <br />Carlsbad Seawater Desalination Conveyance Pipeline, KSD Joint Venture, Carlsbad, CA. 2015. <br />Design Engineer. Engineering design for the Carlsbad Conveyance Pipeline Design -Build Project. The <br />project was designed for the Kiewit Shea Desalination Joint Venture team and consists of <br />approximately 10 miles of 54-inch welded steel pipe. The pipeline was installed in existing city streets <br />and right-of-way through the cities of Carlsbad, Vista, and San Marcos. Large diameter tunnels are <br />being used to cross a major commuter rail line, an Interstate Highway, and protected wetlands at the <br />entrance to a seawater lagoon. The 54-inch transmission main is sized for 54 million gallons per day of <br />desalinated seawater. Pressures range from 250 psi at the point of connection to 500 psi at the <br />seawater desalination plant. <br />Sand Canyon Grade Separation, Irvine Ranch Water District, Irvine, CA. 2010. Design Engineer. <br />Design services for the relocation of over 5,000 linear feet of 8- to 24-inch potable pipeline in the City of <br />Irvine as part of the Roadway Grade Separation for the Railroad. The project also included the design <br />of 2,000 feet of 16-inch recycled waterline. <br />Ohio Street and Oriente Drive Pipeline Replacement, Yorba Linda Water District, Yorba Linda, <br />CA. 2010. Design Engineer. Design improvements for approximately 3,000 feet of 16-inch ductile iron <br />and 1,000 feet of PVC water main to replace existing cast iron water mains within the City of Yorba <br />Linda.
