<br />Groundwater Reliability Improvement Program (GRIP) Advanced Water Treatment Facility, Water
<br />Replenishment District of Southern California, Pico Rivera, CA, 2016-2019 — Structural Designer, assisted with the
<br />design for a new 13,000 acre-feet per year of fully advanced treated recycled water. The structures include a two-story
<br />Administration Building with a rooftop garden, a 45,000 square foot Process Building, a 3 million gallon buried concrete
<br />Equalization Tank and a dozen ancillary structures. The Administration Building has rigid floor and roof diaphragms and
<br />main as are concentric steel braced frames as the lateral force resisting elements. The Process Building has a steel framed
<br />roof and concrete masonry shear walls. An extensive network of cable trays and piping are supported from the roof for
<br />gravity and seismic loads. The Equalization Tank is a buried, rectangular concrete structure designed in accordance with
<br />ACI 350. The ancillary structures are a combination of reinforced concrete, steel and masonry construction.
<br />San Diego County Water Authority, Hubbard Hill North (Q0204) Project, San Diego, CA 2017-2017 — Structural
<br />Designer assisting with the structural design for the First Aqueduct Structures, FCFs and Lining Rehabilitation. The project
<br />will remove the internal lining from the steel portions of Pipelines 1 and 2 in the San Luis Rey river valley, and Pipeline 1
<br />in Couser Canyon and the Lake Hodges river valley. 12 access portals are required for this operation. New reinforced
<br />concrete vaults and pipe encasement will be added or replaced the existing structure at most of the portals. To facilitate the
<br />extended pipeline shutdowns required to remove the internal lining, the project also includes 9 new reinforced concrete
<br />turnout connections structure at six flow control facilities. Tetra Tech is responsible for the structural designs of all the
<br />access portal vault, the turnout connections structures, pipe encasements and other structural improvements for the six flow
<br />control facilities such as retaining walls and pipe bridging/cap across access road.
<br />Prolacta Bioscience, Structural Engineering Services, City of Industry, CA 2018 - Tetra Tech provided Structural
<br />Engineering Services for structural design of the concrete foundation and anchorage for two 3500L stainless steel tank
<br />inside the existing processing building in the City of Industry. Mr. Quiroz performed visional site reconnaissance, assisted
<br />with the preparation of the structural calculations and the plans and specifications.
