Engineering Excellence for Every Project
Since 1999, Design and Construction, Inc. has specialized in delivering reliable Electrical, Mechanical, and Plumbing design solutions tailored to the unique demands of each project. Serving St. Louis, Missouri, Illinois, and beyond with licensure across 13 states, we bring disciplined engineering expertise where it’s needed most.
Our commitment is simple: to engineer solutions that meet functional needs while staying on time and within budget. Each design is carefully coordinated with architectural frameworks and other building systems, ensuring an outcome that performs reliably and meets aesthetic expectations. We listen to our clients, understand their objectives, and provide technical solutions that support architects, owners, and design-build contractors alike.
With precision-driven designs, we are here to build success from the ground up.
At Design and Construction, Inc., we prioritize listening as the foundation of every project. We see ourselves as an integral part of the design team, committed to asking the right questions and delivering practical solutions, promptly. Our goal is to identify any design or code-related issues early—before they turn into costly challenges on-site.
Our designs balance form and function, enhancing the architectural vision while meeting rigorous engineering standards. With our experience and expertise, we can provide plan-and-spec, design-build, or design-build-assist services, adapting to meet the specific requirements of each client.
Our services cover all MEP and Fire Alarm needs, built on five core competencies: Design, Engineering, Electrical, Mechanical, and Plumbing. Wherever you need our expertise, we’re here to help.
