Felix P. Jaecklin Dr. sc. tech (Ph.D.), Dipl. Ing. (M. Sc.), both at the Federal Institute of Technology, Zurich, Switzerland, E., Reg. Civil Eng. CA 20133, Euring, MASCE, Ing. SIA

Dr. Jaecklin, from 1974 – 2000, was the owner and president of the geotechnical consulting company ‘Dr. Felix P. Jaecklin, Geotechnical Engineering’, for geotechnical design in deep excavations, shoring, piling, retaining walls. Since 2000, Dr. Jaecklin has served as an expert witness in the public courts in Switzerland, and as a consultant developing numerous types of precast concrete designs for Evergreen Wall licensees for retaining wall projects in North America, Middle East and Europe.

Dr. Jaecklin has also served as the President of the Swiss committee to establish code on deep excavations. He was one of founding members of the German Commitee on Foundation Engineering to establish a recommendation “Design and Construction of Cribwalls” printed 1985, 2006 and 2016 – still the only code for cribwalls.  That code now exists in an English version about ready for printing.

He has written numerous papers and holds about 31 patents on retaining walls. He is a Registered Civil Engineer) in California, RCE 20’133.

Prior to creating the Evergreen Wall, Dr. Jaecklin was a member of the ‘Emch und Berger AG’, the largest engineering company in Bern, Switzerland with 15 Swiss subsidiaries, and was responsible for research and development, coordination of the structural, geotechnical, and geophysics for larger projects, and member of the board of for ‘Geotechnical Institute AG’ and ‘Geophysical Institute AG’.

In the 1960s, he was an associate of W. A. Wahler and Associates in Palo Alto, California, and was responsible for the first earth-fill dam seismic design in California (the Auld Valley Dam for the Metropolitan Water District in Los Angeles) and the Copper Tailing Dams in Chile. This work resulted in a paper presented at the International Society for Soil Mechanics and Foundation Engineering at the International Conference in Mexico 1970.

In 2000, Dr. Jaecklin received the Excellence in Technology Award “Honoring Excellence in the Application of a new practice and design approach… for combined technology and environmental considerations…” from the International Erosion Control Association (IECA) for the highest retaining wall ever built in Europe, a 92 ft. (28 meter) high wall supporting the highway in Ponferrada, Spain.
