Project Summary

This is one of our first jobs in Irvine and it was the pivotable project that helped us get fire department approval in Irvine and other cities in Southern California. Photo 3 shows fire department testing of the system. Invisible Structures’ Cofounder, Bill Bohnhoff, went to the site along with our representative since 1983 Al Lastuck who was amazed to see the 100 foot ladder truck fully supported on its outriggers setting on our product filled with sand and over top of base course. This was an exciting day in the history of our company.
