Geotechnical Engineering


Geotechnical engineering is the branch of civil engineering concerned with the engineering behavior of earth materials. Geotechnical engineering includes investigating existing subsurface conditions and materials; assessing risks posed by site conditions; designing earthworks and structure foundations; and monitoring site conditions, earthwork and foundation construction.

Construction project reviews have consistently shown a major factor in delay and cost overrun to be the unforeseen conditions in the ground. The provision of solutions requires a thorough understanding of soil, rock and groundwater interactions.

Cost-effective site investigation, combined with experienced interpretation of the data collected, is an essential element of project risk assessment and management.

We provide complete feasibility assessment, design and project management service in all aspects of ground engineering, we are able to combine knowledge with experience to provide cost effective solutions.
