Who We Help
We’re a professional services firm specializing in Surveying, Engineering, and Design-build. CEC can navigate projects in a variety of industries, including Municipal/Governmental, Industrial, and Private/Commercial, to transform the community and these businesses for the better.
CEC is one of the area’s top civil engineering companies, but it is so much more.
CEC is a professional services firm specializing in civil engineering, structural engineering, environmental engineering, process engineering, survey, drone surveying, program management, and more. CEC uses its experience in multiple areas of engineering and design to provide high-quality, lasting work for public and private entities throughout the Sioux City Metro area.
CEC uses its engineering expertise to design projects that its sister company, RP Constructors, builds. CEC’s engineers think like contractors because they are builders at heart. That forward-thinking approach provides clients with design and building solutions that will last beyond today and for years to come.

We complete your job on time, within budget, and with quality and safety in mind.
Industrial
CEC provides the design and planning for industrial construction projects. CEC can design projects from the ground up or improve existing ones. CEC has reworked design plans and created simpler solutions that ended up saving clients time and money. CEC’s engineers are builders themselves and design projects with the contractor in mind. Industrial construction clients benefit from CEC’s expertise in vertical building techniques, wastewater plans, and safety requirements.

Private / Commercial
Private and commercial clients require an efficient process that begins with a concept drawing, so construction on the site work or foundation can start while the rest of the project is still in the design phase.
CEC’s full-service solution allows us to complete all surveying, engineering, and construction in-house and relay those plans to our construction team. CEC’s streamlined process eliminates the chance for anyone to drop the ball when communicating across different teams. Surveyors know what our engineers need, and our engineers understand what our constructors need.
Some of the private/commercial projects we’ve worked on:
Lazy H - Akron, Iowa
W Okoboji Harbor Association - Spirit Lake, Iowa
Interbake Foods - North Sioux City, South Dakota
Several confidential food/processing companies in the Sioux City metro area
