GEM Inc., a member of the Rudolph Libbe Group and specializing in such multiple trades as electrical, mechanical and fabrication, is “very much self-performing,” says Ron Donnal, vice president, business development. By “owning the whole,” says Donnal, “we like to think we look at projects a lot like the owner does. Success isn’t defined by any one discipline; it is defined by the total project goals.” Or, as another longtime company executive Douglas Heyman puts it, there is “one throat to choke,” should a problem arise. “You can’t point at the structural steel contractor; you can’t point at the piping contractor. That’s us.”
