Our People

Dr. Arenas is a Principal Civil Engineer with 25 years of experience in geotechnical engineering. He has led important geotechnical and structural designs, such as Concrete Faced Rock Dams (CFRD), Mechanically Stabilized Earth (MSE) walls, waste dumps and tailings storage facilities. He has conducted Dam Safety Review (DSR) assessments and TSF inspections. Additionally, he has assessed slope stability and liquefaction potential for a multitude of projects. He has conducted seismic hazard analysis, including spectral matching of real seismic events and has conducted several dam breach analyses. He has been the leader for numerical modelling in the civil and mining sectors, having developed this role in south America and Australia.

He has led a multitude of analyses using FLAC/FLAC3D. He has modelled static and dynamic conditions, incorporating liquefaction potential analysis and cyclic compaction, using advanced constitutive models. He has developed a series of methodologies for delivering numerical analyses in a such a way that allow for the delivery of results in a short time and at reasonable low cost. Finally, he has developed a standalone software for producing high efficiency meshes for FLAC and FLAC3D within few hours. He has worked for different client sectors, including numerical analyses for NASA, forensic analyses of civil structures under.
