REQUEST FOR PROPOSAL <br />On -Call Water Resources Engineering Services <br />(RFP N0.19-700) ,nw �fI it <br />of the 18-inch Coto de Caza Trunk Sewer and development of s phasing plan to maintain sewer flows at <br />all times. <br />Santa Margarita Water District (SMWD) Middle Chiquita Canyon Water Facilities, Orange County, <br />California. Santa Margarita Water District. Project Manager. Michael Baker provided preliminary and final <br />design services for a total of approximately 23,200 linear feet (LF) of domestic and recycled water <br />transmission mains, two 2.0 MG domestic water reservoirs, and one 4.0 MG recycled water reservoir, <br />which serve the Rancho Mission Viejo Company's Sendero and Esencia Developments. The project also <br />included: alternative pipeline alignment analysis for routes through environmentally sensitive areas and <br />agricultural areas; grading phasing analysis, and coordination with the Rancho Mission Viejo Company, <br />California Department of Public Health, San Diego Gas and Electric, and the California Department of Fish <br />and Wildlife. <br />Turnout Stations Meter Replacement, Costa Mesa, California. Mesa Water District. Project Manager. <br />Responsible for instrumentation and controls. Michael Baker provided design engineering and construction <br />phase support services for the replacement of flow meters and piping at three water import stations on the <br />OC-44 transmission main. Work under this project included rehabilitating the existing Cla-Val control valves <br />in each vault, replacing all piping, and installing electromagnetic flow meters. <br />Santa Ana Station Refurbishment, Costa Mesa, California. Mesa Water District. Project Manager. <br />Michael Baker provided design engineering for the refurbishment of the Santa Ana Avenue Pressure <br />Reducing Station, which is a pressure -reducing facility located in a below -grade vault on Mesa Water's <br />OC-44 Transmission Main. Refurbishments included the replacement of two 16-inch butterfly valves, <br />relocating existing 16-inch pressure relief assembly to an above -ground configuration, removal and <br />replacement of 6-inch bypass assembly, and reconfiguration of existing pressure reducing valves. <br />Downey Wells, Downey, California. Geoscience. Project Manager. As part of a consultant team, Michael <br />Baker provided engineering services for the design, installation, and equipping of two new groundwater <br />wells for the city's water system. The goal was to design, drill, develop, and equip two new deep, high - <br />capacity groundwater wells that will enhance the city's ability to provide reliable, high -quality, cost-effective <br />water service to its current and future customers. With each well anticipated to supply 2,500 gallons of <br />water per minute to the city's distribution potable system, the combined total well production could account <br />for 25 percent of the city's future potable water needs. The project began with a comprehensive <br />geohydrological, engineering, and hydraulic assessment of six alternative well sites currently in <br />consideration. This assessment addressed site -specific needs, evaluated site suitability for well <br />construction and operation, and identified required off -site pipeline facilities. Two preferred sites were <br />selected. Michael Baker's subsequent tasks included ensuring environmental and regulatory permitting <br />compliance; preparing a preliminary design report; developing design plans and technical specifications <br />for the equipping of both wells; and providing engineering support, construction coordination, and <br />inspection services during construction. <br />Reservoir Engineering Services, Chino Hills, California. City of Chino Hills. Project Manager. Michael <br />Baker is providing engineering services for the Reservoir No. 18 Project. The project consists of <br />demolishing the city's existing 1-million-gallon (MG) Reservoir No. 1, which is deteriorating and nearing <br />the end of its design life, and replacing it with the new Reservoir No. 18. The proposed reservoir will be a <br />3.9 MG, partially -buried, pre -stressed concrete tank <br />Proposal I Page R-2 On -Call Water Resources RFP No. 19-100 <br />I N T E R N AT I O N A <br />
