45 Years in Business


DΞC has worked with numerous local municipalities and counties across New Mexico since opening for business in 1975.
Modern infrastructure is vital to quality-of-life, no matter where you live.  We value the countless opportunities to help build strong, resilient places where families and businesses can thrive. That’s always been our focus. Partnering with New Mexican communities to design and engineer more desirable places to live and work is what we thrive on.

Helping Community Leaders Make Informed Decisions

We design and improve infrastructure and public works projects for municipalities and counties with highly-personalized service tailored for every situation with its unique requirements and needs. Every project has its own challenges. Every community has distinct goals. And we have the experience to recognize the differences. Each project designed and engineered with your individual goals in mind.
