Practical Experience

1. Consulting Engineer in the Institute of Soil Mechanics and Rock Mechanics, Uni-versity of Karlsruhe in the fields of:

• Foundation of structures on soft ground.• Stability of slopes.• Determination of soil parameters in the case of an earthquake for the foundation

of a nuclear power plant (Triaxial cyclic tests, Resonant Column Tests).

• Measurements of surface wave-fields caused by traveling trains in the closeproximity and prediction about the disturbances in the environment by highertrain velocities, 1980-date.

2. Leader of the measurement, monitoring and control engineering group in the founda-tion engineering division of the head office of the construction company BILFINGER& BERGER BAUAKTIENGESELLSCHAFT, 1.5.1989 - 31.12.1990.

• During the employment with this construction company the following meth-ods and techniques have been developed and successfully implemented in thefoundation practise:

6

(a) Horizontal directional drilling in soils for long boring distances (ca. 100m).

(b) Determination of the minimum achieved diameter for jet grouted columnsin soils by measurement of the intensity of noise via hydrophones duringthe jet grouting process.

(c) Further development and in situ use of a high precision tube leveling mon-itoring system based on the principles of electric capacity.

3. Site agent and project engineer for foundation engineering construction sites of theBILFINGER & BERGER BAUAKTIENGESSELSCHAFT, 01.05.1989 - 31.12.1990

• Foundation of the Park & Ride Project of the Railway Station of Gießen.The executed foundation works comprises the construction of bored piles (Ø90,120,150 cm), grouted anchors (and nails), retaining walls (gravity as well asbored pile wall), shooting concrete between the individual piles of the retainingwall, dewatering and absorbing water wells.

• Construction of a cement-free slurry wall as a vertical diaphragm surroundingan aggressive landfill deposit in Braubach (Germany). The slurry has beendesigned without the use of cement as a binder.

• Construction of large diameter bored piles (Ø 150 cm) using floating elementsto support the excavating equipment units inside the Main - river (Germany)for the foundation of the piers of the Main - bridge in Stockstadt.

4. Technical Manager of the company LEIGHTON-BRÜCKNER FOUNDATION EN-GINEERING LTD. in Hong Kong and Thailand (01.01.1991 - 31.12.1993).

• During the employment as a technical manager of the company the respon-sibility for the technical performance and development of the company wasextended to all construction sites and projects of the company in the South -East Asian region.

5. Head of the central division for technical services of BRÜCKNER GRUNDBAUGmbH (01.01.1994 - 31.03.1998)

• During the employment as the head of the technical department the respon-sibility for the activities of the company in Germany as well as abroad hasbeen extended including the following divisions: Technical Development, Me-chanical Engineering Departement, Marketing, EDP(electronic data processingdivision), Research and Development, Quality control, contracting as well asthe superior head of all the technical offices of the company.Among the large number of foundation projects executed by the company thefollowing well known large foundation projects in Berlin are mentioned here:

– Daimler - Benz basement Project including the regional railway station atPotsdamer Platz in Berlin

7

– Lehrter (future central railway station of Berlin) railway station excavationpits

• The following important development during this activity have been achieved:– Method to increase the capacity by deep compaction of waste pits, which

have conventionally be compacted and filled with old waste. This methodhas been used in many old landfields in Germany to increase their capacity.

– Tool for the determination of the position of boreholes or diaphragm wallpanels in space using gyroscopes.

– A new system of removable grout strand anchor has been developed andtested on construction sites. The principle of the system is a cone, whichcan be removed after the service period through the fixed anchor lengthbreaking off the grout in pieces. This systems has been successfully testedto anchor lengths up to 60 meters.
