Our Story
Old School Construction, "Our Roots and Our Vision"
We are a Commercial GC specializing in Electrical, Plumbing, Mechanical, Structural and HVAC. We specialize in design-build value engineering.
OSC can help you with all of your commercial construction needs.
- Our goal is to always maximize your investment dollars by using proven "old school" construction methods, quality materials, technological advancements AND paying careful attention to the details!
- Many commercial projects don't necessarily fall into a specific category, but that doesn't mean the need doesn't exist. Our expertise in "CUSTOM" projects is the result of our repeat clients' trust in our ability to design, innovate and work with them in a collaborative and creative manner.
