What We Do

Comprehensive services, and then some

Sonnikson is an open shop civil, mechanical, structural and general contractor that is proud to serve the manufacturing, agricultural, process and power industries. For 30 years, and counting, we’ve built a reputation of being the gold standard of quality, safety and integrity that businesses turn to when they want the job done right, every time.

By performing all civil, structural, process piping, mechanical and management services in-house, we are capable of executing a wide range of projects while minimizing costs and maximizing quality. At the root of everything we do is the excellent relationship we pride ourselves on maintaining with our customers, with communication a key component of these relationships to ensure we understand and then exceed expectations.
DeliverING Reliable Project Pricing
You can’t build great things without a strong foundation, and that is especially true when it comes to the first step of every project; the cost estimate. Our team is staffed with experienced estimators who deeply understand the value of an accurate estimated cost and practice with integrity. We would love the opportunity to earn your business with a free estimate.
Guiding Your Project from Idea to Completion
The process from idea to the build, and every step in between, is just important as the final product. At every step of the way, we are here to guide you, minimizing cost and maximizing quality; from design to permitting to building and everything in between, big or small, we can help.
Project Management
Excellence from Start to Finish
From the workforce on the job to the leadership at the top, we foster a culture of exceptional project management all the way through. This is done through high-quality construction management systems, unmatched customer service and communication and transparency every step of the way.
Project Consulting
Mitigating Risks, Maximizing Project Potential
When our partners succeed, the entire industry does. If you are in the planning stages of a project and would like consulting to help foresee unknowns, our team would be happy to assist you at whatever phase you’re currently in.
