Concrete Seismic Retrofit: Los Angeles’ Cost-effective Solutions

The goal of the ordinance is to reduce structural deficiencies and improve the performance of targeted non-ductile concrete buildings in the event of an earthquake. Without proper strengthening, these buildings may experience structural failure during and/or after an earthquake. Concrete buildings constructed before January 1977 with a roof and/or floor supported by a concrete wall or concrete column, require a seismic retrofit.

The award-winning concrete seismic retrofit of Los Angeles’ City Hall was led by the Clark Construction Group and required 30,000 cubic yards of concrete, 3,000 tons of structural steel, and 5,000 tons of reinforcing steel. Part of the project included adding reinforced concrete shear walls to strengthen existing masonry walls. Conco was also proud to be involved in the $231-million seismic retrofit and renovation of the L.A. Hall of Justice that was extensively damaged in the 1994 Northridge earthquake. During the project, we implemented cost-effective solutions including using shotcrete to construct walls faster and with less material to save both time and money.

For the best outcome and to minimize costs, these types of projects require experience as well as innovative thinking – Conco has plenty of both!
