I am pleased to write this note about our working relationship with GSI. My experience with them has been excellent. They have a great team of people from engineering to construction. GSI is a fast acting group who puts a solid proven solution to work in a very quick manner. Their field personnel are well schooled on their construction methods and quite efficient when providing the services required to meet design. It has been refreshing to work with this group, as they are professional from design to implementation.
