Tri-axial Soil Testing

This service is one of the most important working units that produce maps for all water related Projects based on Satellite Imagery, Arial Photograph, EMA (Ethiopian Mapping Agency), Base Map and Ground Surveying undertaken. It also provides CAD and GIS services, which will be an input for further detail engineering design study. In addition, the unit supervises implementation of Projects to construct all designed structures as per their working drawings.

The unit delivers the service both for the in-house Projects and external customers.

The service is equipped with modern soft wares and instruments such as Fixed GPS, Total Station, Digitizer, Electronic and manual Theodolihts...etc
