City of Kent, Blue Boy Seismic Retrofit

Kent, Washington | Owner: City of Kent | Architect: City of Kent | Completion Date:

Quantum Consulting Engineers performed a detailed analysis of the 94’ tall, steel, one million gallon standpipe tank in Kent Washington. The tank was built in 1965 and did not have sufficient base anchorage connections to resist overturning forces based on the latest standards. The tank walls were also found to be too thin to meet current tank design requirements. The retrofit design for the tank provided a reinforced connection to the foundation that also stiffened the tank walls to prevent local buckling of the tank walls during a seismic event. As part of our scope of work we provided a specification for a flexible coupler between the tank and the existing water main.
