BRADY will assign individual task leaders to work in tandem to complete the critical path items. <br />TASK LEADE <br />AREA OF RESPONSIBILITY <br />Garrett Murawsky, P.E. <br />Existing Condition and Utilities <br />Richard Brady, P.E., BCEE <br />Confirm Hydraulic Assumptions <br />Howard Johnson <br />George Murdoch <br />Amanda Del Bello, P.E. <br />Interior Dives and Interior Condition Assessment <br />Jacob Finkler, P.E. <br />Randy Smith <br />R. Lee Biggers, P.E., S.E. <br />Seismic Evaluations <br />Max Dykmans, P.E., S.E. <br />Richard Brady, P.E., BCEE <br />Basis of Design Reports <br />George Murdoch <br />Howard Johnson <br />Of specific concern, the City's existing 6 MG South Reservoir will be our immediate focus due to <br />the design similarity to the City of Westminster's 5 MG Pritzker tank failure in 1998. The tank <br />was designed following the "Pritzker" method for prestressed concrete, and became notoriously <br />famous when the City of Westminster's 5 MG Pritzker tank failed catastrophically on September <br />21, 1998 at 5:45 a.m., instantaneously releasing a full 5 million gallons of water into the adjacent <br />residential neighborhood. We are aware that the City reinforced the reservoir following the <br />Westminster failure, and the City's reservoir still in service is partially below grade, making the <br />chance of catastrophic failure unlikely. The only known Pritzker still in service is a 7.5 MG reservoir <br />owned by the City of Upland. For the City of Santa Ana, 21 years has passed since the Westminster <br />failure. The existing reservoir is showing signs of some distress. Spalling concrete is occurring, <br />which means corrosion of reinforcing steel is occurring. Some steel reinforcement is likely now <br />exposed to the elements. <br />RICHARD BRADY &ASSOCIATES, INC. tt <br />r - • • <br />
