Project Manager for the safety evaluation of the 48 ft high brick-mortar intake/outlet tower built in 1892. The dynamic analyses indicated that the tower could not meet the present safety requirements. Subsequently, designed a new inlet/outlet structure to be supported on the upstream face of the dam. Also designed multi-level valves and the outlet structure (pipe) since the original outlet tunnel was found to have a number of broken sections.

Project Manager for the safety evaluation of the 50 ft high intake/outlet tower built in 1905. The structure had survived the 1906 San Francisco earthquake. The analyses, using mode superposition method, indicated that the tower meets the safety requirements.

Project Manager for the dynamic analysis of the 108 ft high outlet tower for an MCE of M6.5 with a peak ground acceleration of 0.6g.
