Services

We provide the following services: Investigation, Design, Specifications and Construction Inspection.
The types of projects with which the company are involved include:

Rock Slopes

Rock engineering of slopes on facilities such as railways, highways and power facilities must have a high degree of reliability and safety for the public. This requires that they be stable against both large-scale failure and rock falls. Learn more

Landslides

In mountainous terrain, large-scale instability may take the form of creep over a period of decades or centuries, or sudden catastrophic collapse. The identification of landslides is vital during the planning stage of a project. Learn more

Tunnels

Engineering tunnels are driven by drill and blast, road header and TBM methods. An issue for all these types of tunnels is support requirements for long term, safe operations. Learn more

Blasting

Issues that often need to be addressed in blasting operations include stability of the final excavated faces, and the control of ground vibrations and noise. Learn more

Foundations

Structures such as bridges and power transmission towers founded on rock may be located on steep slopes. Design issues for these conditions where the structural loads are highly concentrated, include the bearing capacity and stability of the foundation. Learn more
