The maintenance process can be applied to every type of structure, the question is depending on where to start. In close dialogue with the owner of the properties, House Doctors helps to plan the next renovation project, to focus on repairs only where they are needed, and make sure there will not be any bad surprises in order to keep the budget under control.

Biographie

Dr. Alexis Kalogeropoulos

Dr. Alexis Kalogeropoulos is a Founder and CEO at Bridgology. His vision is to keep bridges in the best conditions at the lowest cost possible by implementing so-called Predictive Maintenance. He’s a specialist in Ground Penetrating Radar applied to civil engineering.

In 2005, the first GPR applications were developed for an inspection of tunnels, utility detection and thickness calculations by Karakas & Français SA, however, further development became necessary. As a result, a collaboration of more than 7 years was established with Dr. Johannes Hugenschmidt HSR, which led to the publication of an article on the inspection of retaining walls with GPR; then in obtaining a research grant FNS for a doctorate on the determination of chloride and moisture content in concrete with GPR.

He obtained the Ph.D in 2012, it was held under the joint supervision of Dr. Johannes Hugenschmidt, then at EMPA. of Prof. Eugen Brühwiler EPFL, and of Prof. Jan Van der Kruk ETHZ then FZJ.

Besides Bridgology, he contributes his time to the scientific community as a reviewer for scientific journals like NDT&E International and Near Surface Geophysics. Frequently, he teaches at EPFL in introducing Masters to GPR, and providing digital signal processing teachings to Doctoral school.

Biographie

Dr. Christophe Loraux

Christophe Loraux has joined Bridgology since 2020 as a GPR data analyst and quickly become involved in the development of Bridgology’s in-house analysis software.

With his solid background in civil engineering, he integrated his vision and improved communication with Bridgology’s clients. A few months after he started working, he became skillful at unveiling the most complex and hidden features of existing concrete structures!

During his Bachelor and Master years at the Swiss Federal Institute of Technology in Lausanne, Christophe fell in love with the vast field of existing structures. It’s almost natural that he pursues his studies with a PhD thesis on novel material for the strengthening of concrete bridge decks and long term monitoring of structures.

Currently, Christophe is appointed as a Structural Engineer Consultant in Bridgology’s office – Stockholm. As Remote Working is one of the corporate culture strengths at Bridgogoly, he is able to keep a close cooperation with the Headquarter in Switzerland to solve clients’ problems not only in Sweden, but also from anywhere in the world.
