of overflow pipeline, drain pipeline and sluice <br />gates. Psomas' scope of services includes <br />preliminary and final design; construction <br />plans, specifications, and estimates of probable <br />construction costs; and engineering support <br />during construction. <br />Pelican Hill Golf Club <br />Sewer Pipeline Rehabilitation <br />Newport Beach, CA <br />CLIENT CONTACT: Irvine Ranch Water District <br />15600 Sand Canyon Avenue, Irvine, CA 92618 <br />Christian Kessler, PE, Engineer <br />(949) 543-5441 <br />YEAR COMPLETED: Ongoing <br />KEY PERSONNEL: Maira Salcedo I Michael Swan <br />Benjamin Halbach I Joseph Barrera <br />Irvine Ranch Water District (IRWD) owns and <br />maintains four sewer pipelines that convey flows <br />through the Pelican Hill Golf Club and Pelican Hill <br />Community Association. The four sewer pipelines <br />were constructed in the early 1990s with a mix <br />of polyvinyl chloride (PVC) and ductile iron <br />pipe (DIP) ranging from 8-inch through 12-inch <br />diameter. As part of IRWD's routine CCTV <br />inspection, portions of these areas were found to <br />be experiencing material pitting, and deformation <br />and/or liner failure at various locations. <br />In May 2019, IRWD hired Psomas to evaluate <br />the existing conditions of 6,027 LF of sewer pipe <br />and provide professional design services for <br />the four sewer pipelines. Our NASSCO certified <br />engineers evaluated the CCTV reports and <br />videos. We found the majority of the pipelines <br />were in good overall condition. The final design <br />plans completed in November 2019 resulted <br />in 2,420 LF of lining, 5 LF of root removal, and <br />35 LF of calcium deposit removal. <br />Psomas will also be providing Construction <br />Phase Services including, but not limited to, <br />active participation in construction meetings, <br />review and response to shop drawings and <br />contractor request for information, site visits, and <br />record drawing preparation. <br />F.
