About SEMA

SEMA Construction, Inc. is a full-service construction firm. And at SEMA, we believe a company isn’t defined as much by what they say about conducting their business as it is by what they do in conducting their business. And how do we conduct ours? We do it on time, we do it on budget, and we do it safely. That’s who we are – a general contractor that thrives on doing it right.
