EARTHQUAKE ENGINEERING

Site Specific Seismic Response Analysis (SSRA)

We conduct Site-Specific Seismic Response Analyses (SSRA) to assess a site's seismic risk through DSHA and PSHA. Our services help evaluate potential ground shaking hazards specific to your project's location, allowing us to integrate customized mitigation strategies and seismic design parameters. Using advanced numerical modeling techniques, we provide critical insights for projects in seismically active regions, ensuring compliance with safety standards and enhancing structural resilience.

DSHA

Deterministic Seismic Hazard Analysis

PSHA

Probabilistic Seismic Hazard Analysis

Dynamic Analysis

Advanced Seismic Deformation Analysis

WATER MANAGEMENT
DESIGN

Our Water Management Design services ensure sustainable and efficient water control systems for civil and geotechnical projects. We analyze watershed behavior and water flow dynamics, and design key structures like diversion channels, spillways, and outlet works to manage stormwater and prevent flooding. Additionally, we provide specialized solutions for seepage collection and treatment, protecting groundwater quality and ensuring site stability and environmental compliance.
