About SEMA

Built to work for you

Project owners work with us because we own the equipment and build the projects we undertake. This reassures project owners about schedules. Everyone can look forward to an efficient and productive project— beating or keeping to deadlines without giving an inch on safety.

In terms of technical specifications, we’re a full-service contracting company with over 31 years of leadership in heavy civil and industrial construction. About 80% of our construction services are for government entities, with the majority awarded via a competitive bid process including traditional, design-build, and CM/GC.
