Our History

Established by Ray Duggins in 1961, Duggins Construction Inc. quickly became one of the elite construction companies in the Imperial Valley. Ray’s vision was to always provide the best service possible to his clients. Built on a strong work ethic and quality craftsmanship, DCI has also always been a family business. Ray’s son, Jim Duggins learned the construction business from his father and would eventually lead the company.

After Ray’s retirement in 1987, Jim became president of DCI and like his father, held steadfast in creating valued client relationships. Jim expanded the capabilities of DCI as he began building a larger variety of commercial and industrial facilities. The small jobs lead the way to larger projects for major franchise auto dealerships, retail centers, healthcare owners, professional office buildings, churches, financial facilities, government projects, restaurants, educational facilities, agricultural facilities, grocery stores, distribution and warehouse facilities and other projects which continue to add to our diverse background.

In 1985, Russell Roben joined the DCI team and ushered in new techniques and ideas which helped reinforce an already robust construction division. Within a few years, Russell would become a partner and the Vice-President of the company. After Jim’s retirement in 2016, Russell was named President of DCI.

Oscar Grijalva came on board in 1988 and established our Design Division. His experience and knowledge brought cutting edge CAD technology to the company along with new architectural concepts. Oscar is a partner of the company, as well as our General Manager and Vice-President.

Allen Roben has been around construction his entire life. In his youth, he worked part-time during summer breaks at DCI. In early 2002, Allen joined the steel crew as a full-time team member. Helping to advance the steel division, he shortly after was promoted to a crew foreman and eventually advanced to the Steel Division Manager. Allen is DCI’s Secretary/Treasurer officer.

Today, we are committed to uphold the values established by our founder Ray Duggins. Our continued growth and success of can be attributed to a high percentage of repeat customers. Our goal is not to just build for you - our goal is to be your “Partner in Development.”

Our Facility

For over 46 years, our original headquarters was a small office building with a shop located in El Centro, CA. Thru the years we remodeled and expanded our facility to accommodate our needs.

For over 10 years, we had planned and discussed the possibility of moving to a new location and building our own facility from the ground up to provide a better work environment for our employees as well as our clients. Finally in 2007, we broke ground on a new facility which was completed later that same year.

In designing our new headquarters, we created a working showroom of many different construction materials to display our clients and visitors. We invite you to visit us and allow us to show you some of the latest construction materials and ideas available for our clients.
