Engineering has been an aspect of life since the beginnings of human existence. The earliest practice of civil engineering may have commenced between 2000 and 4000 BC in Ancient Egypt and Mesopotamia (Ancient Iraq) when humans started to abandon a nomadic existence, creating a need for the construction of shelter. During this time, transportation became increasingly important, leading to the development of the wheel and sailing. In the 18th century, the term civil engineering was coined to incorporate all things civilian, as opposed to military engineering. GAST has since the early 90’s provided various design and installation services to multi-faceted  clients worldwide, predominately specializing in Geotechnical Engineering, Bulk Earth Works, Water Resource Engineering, Surveying, Bulk Water Supply, Sewage, Municipal / Urban Engineering and Hydraulic Engineering.
