Borehole Information

Our Borehole Information System (BIS) is a state-of-the-art database developed to store and manage comprehensive ground information obtained during the planning and construction phases of any LTA project. This web-based Geographical Information System (GIS) allows multiple users to search, view and download ground information using a web browser.

To-date, the database offers information on 14,000 boreholes and is continually expanded when more information is gathered from new boreholes.

As our boreholes are generally deep, the information provided is comprehensive and augmented with various laboratory and in-situ tests.
