Ing. Mario Terceros H.

Ing. Terceros H. is a geotechnical and foundations veteran engineer with more than 35 years of experience in the design and construction of special and deep foundation projects. He introduced the use of Expander Body in South America during the 1990's and developed new versions of the technology, including the post grouting system. He introduced several new technologies for the construction of deep foundations in South America and he developed the Toe Box device. He has extensive experience in sedimentary soils below the phreatic level. He has participated in international projects as a consultant and is also a professor of postgraduate courses at Bolivian universities.

Dr. Bengt H. Fellenius Dr. Tech. P.Ing.

Dr. Tech. Bengt Fellenius  was Professor of Civil Engineering at the University of Ottawa for 20 years, but most of his to-date almost 60 years of engineering work have been spent in the contracting and consulting engineering field, dealing with a wide variety of assignments that encompass foundation design for industrial plants, water and sewage treatment facilities, bridges and highway projects, marine structures, and urban area development, as well as participation in special investigations, instrumented field tests, etc. In 1977, he was the third geotechnical consultant to acquire the Pile Driving Analyzer for use in connection with pile driving projects. He is an internationally active foundation engineering consultant and the author of some 400 technical papers mostly addressing pile driving and piled foundations, but also other topics of his interests, such as soil improvement, foundation settlement, in-situ sounding, and vibratory compaction and liquefaction remediation. Dr. Fellenius has given lectures and courses to several universities and international conferences throughout North and South America, Europe, and South-East Asia. He currently lives in Sidney, BC, Canada.

Ing. Mario Terceros Arce

Ing. Mario Terceros Arce studied Civil Engineering at Tecnológico de Monterrey (ITESM) between 2009 and 2013. During this period, he carried out a one-and-a-half-year exchange program with the Technical University of Munich (TUM) in Germany, where his passion for geotechnics and deep foundations awoke. After the academic program, he carried out professional internships at BAUER GMBH before returning to Mexico to finish his studies.

​

After finishing his studies, he returns to Bolivia in January 2014 where he begins to work at INCOTEC as the head of studies and quality tests, gaining great experience in the execution and evaluation of various geotechnical studies (CPTu, DMT, PMT, SPT, etc) and quality tests (PIT, PDA, CSL, etc.). Subsequently, he worked as an engineering manager until the year 2015. In the year 2016, he became chairman of the board of directors as well as operational vice president, which he remains to the date. He is currently completing his master's degree in geotechnics at the San Francisco Xavier University in Chuquisaca.

​

He is currently the Presidential Group of Young Members (YMPG) of the International Society of Geotechnics (ISSMGE), being one of the three representatives of South America. Ing. Terceros is has also been a member of the organizing committee of the International Congresses of Deep Foundations of Bolivia.
