AT&T Park

San Francisco, California


Clients throughout California and other seismically active regions count on the seismic and ground motion services provided by Langan. Our engineers evaluate the potential for fault rupture, soil failure, and ground deformation to develop detailed site-specific ground motion criteria for seismic design. Services provided include:

• Field mapping of seismic sources
• Development of probabilistic and deterministic site-specific response spectra
• Nonlinear and equivalent-linear ground response analyses
• Development of site-specific time histories
• Seismic stability of natural and artificial slopes, including deformation analyses
• Seismic evaluation of landfills
• Soil-structure interaction analyses
• Evaluation of liquefaction potential and associated deformations
• Liquefaction mitigation alternatives
