<br />Morro Hills No. 1 and 2 Reservoir Repairs and Booster Pump Station, City of Oceanside, California. Served as
<br />project manager for the detailed design of repairs to an existing 5.0-MG prestressed concrete reservoir and a 5.0-
<br />MG welded steel reservoir on a common site. Improvements to the reservoirs included replacing piping, buried
<br />and exposed valves, and appurtenances, adding inlet and outlet flow meters, and recoating. In addition, the
<br />prestressed concrete Morro Hills No. 1 reservoir required repairs of concrete spalling and cracks, rewrapping of
<br />and anchorage to address seismic deficiencies, and a new underdrain system. To accommodate the seismic
<br />retrofit, removal and replacement of the inlet/outlet vault and Morro Hills booster pump station was required. The
<br />new BPS consists of three 60-hp multi -stage vertical pumps with a design capacity of 1.5-MGD at 320-foot TDH.
<br />The pump station includes an emergency generator and water quality instrumentation and was designed to the
<br />City's specifications for architecture and 0&M access to the pumps and appurtenant electrical and control
<br />equipment. The project also included various site grading, drainage, and fencing improvements.
<br />13.4-MG Goetz Road Tank, Eastern Municipal Water District, City of Perris, Riverside County, California. Served as
<br />project manager for the preliminary and final design of a 13.4-MG pre -stressed Type 1 concrete tank. Other
<br />design features on the tank site included 30-inch CML&C steel inlet and outlet piping, an altitude valve and check
<br />valve vault, reservoir mixing system, and chloramination boosting facility, site grading to partially conceal the tank
<br />and addressing site drainage for approximately 100-cfs that naturally drained through the site. The project also
<br />included hydraulic analyses to size the 30-inch transmission main and an alignment analysis that used a matrix
<br />rating system which scored each alignment in 10 different categories.
<br />10.6-MG Roof Repairs and Rehabilitation for Dearborn Reservoir, City of Redlands, California. Served as project
<br />manager, responsible for engineering design services (preliminary design, final design, bidding period, and
<br />construction support services) for rehabilitation of their 10.6 MG Dearborn Reservoir. Initially, the City was
<br />advised that replacing the pre -stressed roof was required but did not have sufficient budget. The Dudek team
<br />reassessed the roof and developed a roof rehabilitation and repair alternative that was 50% of the cost of the
<br />City's original budget and 25% of the replacement cost for a new roof. The solution included fiber reinforcement
<br />of the cracked roof surface over the columns, new concrete drop panels, concrete jacketing the columns,
<br />enlargement of the concrete column footings, adding a concrete curb at the wall/floor interface to meet sheet the
<br />shear requirements of the current code, fiber reinforcement of the roof support beam that supported the two roof
<br />diaphragms, and miscellaneous repairs to the roof edges. Dudek prepared construction documents (drawings,
<br />specifications, bidding forms, and an engineer's estimate) for the reservoir's roof rehabilitation and repair.
<br />Ogden Reservoir, San Bernardino Municipal Water Department, City of San Bernardino, San Bernardino County,
<br />California. Served as project manager for design of a 12.0-million-gallon (MG) pre -stressed concrete reservoir, site
<br />piping, and appurtenances. The reservoir had to be designed to float with the other reservoirs in the 1416 Zone,
<br />serve as a forebay for the Ogden pump station which mandated raising the floor considerably, and minimize
<br />grading and disruption to the existing site facilities and adjacent structures and utilities in Ogden Street.
<br />Preliminary design activities included optimization of the site and maximizing the storage volume of the reservoir
<br />while not disturbing the recently constructed on -site facilities such as the 18,000-gpm booster pump station, 36-
<br />inch transmission main piping/valving/appurtenances, percolation basin and the 12kV switchboard, electric feed
<br />and SCE transformer. To accomplish this, extensive coordination between the structural engineer, geotechnical
<br />engineer and DN Tanks was required to minimize over -excavation, shoring and project construction costs while
<br />achieving the other project objectives.
<br />Burruel Reservoir Upgrades, City of Anaheim, Orange County, California. Served as project manager for
<br />preliminary design, final design, and construction support services for miscellaneous upgrades and recoating
<br />(including lead paint removal/abatement) of the 0.75-MG steel reservoir. Upgrades to the reservoir and site
<br />included piping, valving, enlargment and replacement of the roof hatch, safety upgrades (handrailing, lighting,
<br />and signage), replacement of the interior ladder, and site repaving.
