About TAGAsoft
Engineering software built by engineers, for engineers.
TAGAsoft was founded in 1981 in Berkeley, California in response to client demand for practical geotechnical applications. Over the years, the TAGAsoft suite expanded to include a range of tools used by consultants and academics worldwide.
The name TAGA comes from Telegraph Avenue Geotechnical Associates — a nod to the first office location on Berkeley’s Telegraph Avenue.
Today, TAGAsoft is the trading name of TAGA Engineering Software Ltd, a New Zealand registered company, continuing the original vision: providing geotechnical engineers with software that is powerful, practical, and efficient.
