Analysis included exterior and interior concrete <br />investigations to evaluate condition of prestressing wires and concrete <br />delamination; structural analysis for seismic and gravity loads; <br />Geotechnical investigations; and corrosivity investigation. <br />Recommended improvements included an interior ring wall, chemical <br />injection piping, recirculation pump, value vault, reservoir access, site <br />improvements, landscaping and tank coating. <br /> <br />This .20 MG, 125 feet high tank was constructed in 1940. The tank <br />shell consists of riveted steel plates and is supported by built-up, riveted <br />steel members. The tank and its foundation were originally designed <br />for a horizontal seismic force factor of 0.1 times the dead load of the <br />tank and contents. <br /> <br />ASL performed a seismic evaluation to determine the safe operating <br />water levels of the existing structure. ASL also performed three seismic <br />analyses for three different retrofit design alternatives in accordance <br />with current code standards. Cost estimates for each retrofit alternative, <br />as well as a replacement (new tank) cost were provided. <br /> <br />This .25 MG, 140 feet high tank was constructed in 1936.
