Johan Bosch obtained his master degree of civil engineering at the University of Delft in 1982 and started working with the Construction Company Ballast Nedam. After three years he moved to the city of Amsterdam working on various positions within the municipal organisation. During this period he was involved in the planning of several major projects such as a submerged road tunnel (Piet Heintunnel) and the new metro extension, the North-South metro line. In 1992 he left the municipal organisation and started working as managing director of one of the subdivisions of Tauw, a consulting company active in the fields of civil and environmental engineering. In 1994 he became board member of Tauw. In the same year he renewed his involvement with the North-South metro line project, when he was invited to become manager of the technical matters of the project. Since 1999 he is full time involved in the project as board member and working again for the municipal organisation of Amsterdam. In August 2002 he was appointed as professor at Delft University of Technology. He holds the chair of Underground Space technology (Subsurface Construction). Since 2002 he combines both positions.

Thomas Bles graduated in Civil Engineering and Management at the University of Twente in 2003. At Deltares he works at the unit Foundation Engineering and Underground Construction. At graduation and professionally, Thomas is very much engaged in the risks of realization of different types of pile foundations, sheet piling and horizontal directional drillings. Within these activities, as projectmanager he is directly involved in the development of the GeoBrain experience databases and forecasting models. GeoBrain aims at identifying, assessing and balancing risks of realization already during the design phase of construction projects. In addition to this, Thomas is project manager of the risk-driven soil investigation and pre-design of several crossings of large pipelines with civil engineering works such as dikes and canals. Thomas manages the Delft Cluster/CUR research project on monitoring of building excavations. He is teamleader of Deltares’ risk management team and moderates risk management in Deltares’ scientific council.
