General Industrial

The Industrial Element of Sonnikson and Stordahl Construction has been the core element of our business for many years. We have executed projects as large as complete refinery expansions as well as small maintenance and repair projects. Our exceptional safety records and quality control has helped us maintain a strong working relationship in several large refineries such as Tesoro, Shell, Chevron, Conoco Phillips, and several other large refineries. In addition to these well known refineries, we have experience and working relationships with a number of smaller and/or privately owned industrial facilities as well. We are always interested in developing new working relationships in the industrial marketplace as safety, reliability, and production needs can change every day.

Concrete Work

Our concrete division has over 30 years of experience in industrial style foundations. Whether it is a 300 foot tank foundation or just a small pump pad we can handle it from start to finish including you excavation and grading requirements. We are well aware of the difficulties often faced when working in existing site conditions. For this reason our personnel have been trained with all precautions in mind to make for a safe and productive work environment.


Over the last 15 years, our mechanical division has grown to be able to handle large mechanical expansion or replacement projects, as well as smaller, maintenance related activities. Our staff handles most work in-house including process piping, mechanical work, equipment installations, structural steel, and many other mechanical needs in the refineries. Mechanical personnel have also been trained to be aware of existing refinery conditions allowing this division to contribute to our exceptional safety record.

We hope we have the opportunity to meet your construction and manpower needs and look forward to inclusion in your future.
