MRCE Geotechnical and Foundation Engineering

Challenges Solved

The Torre Reforma 432 tower has 55 levels above grade and deep basement. MRCE performed a seismic hazard analysis for the development, including seismic sources compilation and ground motion parameter development for the Mexico City region. In addition, MRCE performed site-specific response spectra for three required earthquake levels (Service Level with a return period of 43 years, Design Level with a return period of 125 years, and Maximum Considered Earthquake with a return period of 2475 years). Based on the available geotechnical and geophysical data and local seismicity, MRCE developed seven time history acceleration sets at the “bedrock” level to match each of the three site-specific response spectra developed for three return periods. MRCE performed Soil-Structure Interaction (SSI) analyses for the MCE level earthquake.
