Ensoft, Inc., was established in Austin, Texas in 1985 with the principal aim of developing and applying computer-based solutions to complex engineering problems and has since built a strong reputation as a leader in this area. Ensoft has applied advanced technology, much of it based on recent research, in the writing of software for the solution of complex problems that arise in geotechnical and structural engineering. Notable among Ensoft’s computer programs are those that address the analysis and design of foundations employing piles and drilled shafts.
