There's a company called Structure Works and another one called Simplex Grinnell which is owned by Tyco.
I couldn't find a website for Structure Works but have been associated with several people who work for them.

Given the amount of major commercial and industrial sites in this area plus continued growth development I doubt he'll have any problems finding work based on his years of experience.
Good Luck.....!
