Geophysical Surveys

Geophysical survey is a cost-effective, non-intrusive and relatively quick way of detecting and assessing sub-surface features. GEOtech has developed in-house capabilities in geophysics to effectively complement conventional geotechnics for determination of dynamic soil properties, detecting utilities and voids, site characterization, landslide evaluation, etc.

  • Seismic Refraction
  • Electrical resistivity Test

Transportation

The structural condition and functionality of bridges are a significant part of the transportation network. Every project needs to be technically and aesthetically correct, durable, economical, and the most sustainable solution for a given location.

Engineering design for a transportation project is done prior to the commencement of the construction phase and involves the planning and design of the entire project. Upon acceptance of the project together with the client, a decision is made as to the scope and details of the project with the adoption of a zero-based management approach towards the entire design. The zero-based management approach ensures that the design is formulated from scratch to produce designs that are best suited to the clients requirements.

General description of each process is detailed as follow:

Project Identification and Assessment of Needs

During the pre-design phase, the assigned design team will work closely with the client to identify the details of the project which includes the identification of the purpose and location of the site. The design team will also analyze the viability of the project by performing market surveys, preliminary financial modelling, financial feasibility study and risk assessment and management.

Location Study, Land and Geotechnical Survey

The team will then carry out survey on the project site to collect data. This includes the study of the site topography, geotechnical and traffic study. Utilities mapping and infrastructure conditions surveys will be carried out. This will allow for the preparation of the term of reference.
