Opportunities in Times of Crisis
A presentation entitled ‘Never waste a good crisis’ and the current and all-consuming coronavirus outbreak have inspired to look at the opportunities that present themselves in times of crisis. By making sensible decisions, taking clear actions and finding new pathways we will be able to take advantage of future opportunities – for our society, our businesses and our private lives.

High Risk Potential of Hose Lines on modern high-pressure Compressors
Working with high-pressure equipment on construction sites that operate modern air compressors presents a high risk of serious accidents. The article raises awareness to this particular hazard and provides advice on selecting suitable hose line systems and on their correct operation and handling at the workplace.

Innovative high-performance self-drilling Micropiles and their possible Applications
Self-drilling micropiles allow flexible use of drilling equipment, enable the installation of long micropiles even in confined spaces and obtain a high drilling performance with very low vibrations. This article presents an innovative high-performance self-drilling micropile with an internal load bearing capacity of approx. 6,500kN. The further product development and experience gained from installation tests are explained. Furthermore, the efficiency of the use of a bored pile, a group of micropiles or and a single high-performance micropile is compared.

Long-term Experience in Stabilising Slopes with high-tensile Wire Mesh
This article deals with the long-term behaviour of slope stabilisation projects using high-tensile wire mesh. Experience from three case studies from 2000 and 2005, which were visually inspected 11, 13 and 17 years after installation, and investigations of the corrosion-protective coating of the wires are used to estimate the service life.

Technology Trends for mechanised Tunnelling in soft Ground
Since the 1970s in particular mechanised tunnelling technology has been increasing its share of the market at the expense of conventional tunnel engineering, a trend that has seen the development of ever larger tunnelling shields. The paper analyses some 274 individual projects in order to assess the impact of key machine parameters such as shield diameter, drive power, torque and rate of advance. It also traces the way in which these various parameters have developed over time.

Modelling of Lignite Seams targeted by prior Mining Operations
The lignite mining areas of central Europe are increasingly encountering extraction zones that were previously worked by both opencast and underground mining methods, in some cases with significant mining losses. The paper uses the example of Amsdorf opencast mine to present the potential offered by 3D modelling of these areas, which are now attracting interest due to the high demand for natural resources.
