The combination of widely varying terrain and ground conditions combined with rapid development has created the need for a high level of expertise in geotechnical engineering. Specialist knowledge and design input is required for development on slopes or in areas of reclamation and includes the need for detailed submissions for foundations, basements tunnels and slopes in order to meet the guidelines and approval of the Geotechnical Engineering Office and Buildings Department.
ESA has been providing this specialist service since 1980 with engineers who are familiar with the requirements of the Government and can plan, design and supervise the geotechnical elements of new developments or remedial works. They are also available to give advice to Contractors on economical and practical methods of construction in respect of the prevailing ground and groundwater conditions.
Cost effective and innovative solutions have been adopted to overcome natural hazards and man-made problems using:
Monitoring techniques using geophysical and geodetic surveying, inclinometers and piezometers.
GEO Agreement CE 12/96
Design and supervision of landslide prevention measures on behalf Hong Kong Government
No. 1 May Road
Studies of soil: structure interaction
Kau Shat Wan
Mapping of ground conditions and determination of tunnel and cavern supports
LAR 503C Kowloon Station
Insurance investigations of bored piling construction techniques
Tsing Yi Open Space
Extensive re-design of site formation, including the use of artificial rock
