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.

Top Places to Work

We are thrilled that SEMA has been named a Top Workplace by The Denver Post for three years in a row. The list is based solely on employee feedback gathered through a third-party survey measuring several aspects of workplace culture, including alignment, execution, and connection, just to name a few.


A company is only as good as the men and women who serve it. At SEMA, we believe that integrity drives quality. We only hire professional, dependable and honest team members who are experts in their fields. Personal best. This is what we try to foster by challenging our people to new heights while giving them all the tools they need to reach them.  It’s our commitment to the people of SEMA.
