Huntington Beach, CA <br />V&A Consulting Engineers, Inc. (V&A) was <br />retained by Lockwood, Andrews & Newnam, Inc. <br />(LAN) to perform a condition assessment of the <br />Edinger Pump Station to support the Orange <br />County Sanitation District (OCSD) for the Edinger <br />Pump Station Rehabilitation Study in Huntington <br />Beach, CA. The pump station consists of two <br />separate reinforced concrete structures, a <br />circular wet well and a rectangular dry well. It is <br />located beneath the travel way of Edinger Avenue <br />near the intersection of Graham Street. The <br />purpose of the condition assessment was to <br />provide an opinion of the physical conclition and <br />determine remaining service life. Condition <br />assessment methods included visual <br />assessment, concrete surface testing, surface <br />penetrating radar, half -cell potential, <br />galvanostatic pulse testing, and concrete core <br />samples and laboratory testing. <br />Dos Angeles Community College District (LACCD) <br />District-WIds Utility Infrastructure Condition <br />Assessment. Lacs Angeles, CA <br />V&A Consulting Engineers (V&A) was retained by <br />Cardno, Inc. for Condition Assessment (CA) <br />services to support the Los Angeles Community <br />College District (LACCD) across all nine of their <br />campuses. The purpose of the project was to <br />assist LACCD with the future improvement project <br />planning, including budget and estimation of life <br />expectancy as well as the cost of repair or <br />replacement of various utilities throughout the <br />district. The scope of work consisted of multiple <br />utility systems, including potable water, <br />reclaimed water, hydronic water, sanitary sewer, <br />and natural gas. An array of utility testing and <br />tasks performed were visual assessments of <br />above/belowground components and manholes, <br />the ultrasonic thickness of accessible metallic <br />components, leak detections, and confined <br />space entry into the manholes and underground <br />tunnel systems. Also, concrete testing through <br />concrete sounding, concrete penetration, <br />concrete surface pti, surface penetrating radars <br />(SPR), and coating evaluations. The desktop <br />review and assessment of the sanitary sewer <br />pipe conditions are per the NASSCO standards. <br />Also, performed were soil resistivity testing <br />through evaluations for corrosive impact <br />potentials the native soil may have on buried <br />metallic components. We delivered a technical <br />report detailing the results of the condition <br />assessment findings and recommendations for <br />(D <br />improvements, including recommendations for <br />preventive maintenance and rehabilitation using <br />qualitative and quantitative data obtained during <br />the assessments. <br />Encino Wastewater Authority FY 2018 Condition <br />Assessment Services. Carlsbad, CA <br />V&A was retained by Encina Wastewater Authority <br />(EWA) to perform condition assessment services <br />at the Encina Water Pollution Control Facility <br />(EWPCF). Facilities included in the FY-18 <br />assessment include the Outfall and Surge Tower, <br />Dissolved Air Flotation Thickeners (DAFTs), Bar <br />Screen Bypass Lines, and Cogeneration Building. <br />V&A is performing on -site field assessments to <br />determine the condition and remaining service <br />life. Concrete surface assessments include <br />sounding, penetration measurements, surface <br />pH, and surface penetrating radar. UT testing and <br />pit depth measurements will be performed on <br />the metal piping associated with the Surge Tower <br />and DAFTs and GET of coatings presents. <br />Findings and recommendations will be presented <br />to EWA in Condition Assessment Report. <br />Padre Dam Municipal Water District Trans -River <br />Inverted Siphon Condition and Capacity <br />Assessment. Santee, CA <br />V&A Consulting Engineers (V&A) is currently <br />conducting a condition and capacity assessment <br />of approximately 18,000 linear feet of 24-inch <br />Sludge pipeline owned and operated by Padre <br />Dam Municipal Water District (PDMWD) in <br />Santee, CA. The double barrel inverted siphon <br />crossing the San Diego River is the only pipeline <br />that can convey raw primary and secondary <br />sludge flow from the Roy Stover WRF to the San <br />Diego METRO Interceptor and is the focus of the <br />condition assessment. V&A obtained flow <br />monitoring data on each siphon for a two week <br />period per siphon. V&A is also currently <br />conducting a condition assessment methodology <br />evaluation that included the inverted siphons <br />and sludge pipeline in terins of overall cost, ease <br />of implementation, and type and quality of <br />produced data. The evaluation will recommend <br />technologies to be used for the condition <br />assessment. Once final selection is made by <br />PDMWD, a Condition Assessment Work Plan will <br />be developed by V&A for execution of the <br />recommended condition assessment method, <br />access locations, roles and responsibilities, and <br />a revised implementation cost estimate. <br />RICHARD BRADY & ASSOCIATES, INC.
