Reinforcement of existing Deep Foundations with Micropiles

Many existing structures and their deep foundations have to be reinforced or retrofitted – e. g. due to a changed use requiring higher load bearing capacities. Practicable and economical solutions are needed. This paper describes the analysis of interaction between existing bored piles and reinforcing micropiles.

Risk Analyses for geotechnical Tasks using practical Examples in the ‘Europaviertel’ in Frankfurt, Germany

Construction projects are subject to risks, from the project-planning stage through the design phase to the execution phase and the subsequent guarantee period. This paper explains geotechnical risk analyses using selected examples from the Europaviertel project in Frankfurt, Germany.

Perceiving, Comprehending, Projecting and Acting: Situation Awareness in Material Processing

Situation Awareness (SA) describes the comprehensive awareness of a particular situation. According to Endsley a situation is subdivided into the phases of perception, comprehension and projection, which ultimately result in an action. SA is used, for example, in the automotive sector where autonomous vehicles must respond to their environment. In this paper the same principle is being applied to the field of bulk materials transport in order to control and monitor conveying systems. The article demonstrates how Situation Awareness can be used for bulk materials transport systems, with reference to products supplied by the German company Rema Tip Top.
