DEC has worked with dozens of 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. Yet when most engineering firms hear "rural" they think "small time." We on the other hand, imagine the countless opportunities to help build strong, resilient places where families and businesses can thrive. That's always been our focus. We partner with New Mexican communities to design and engineer more desirable places to live and work.
We design and improve infrastructure and public works projects for municipalities and counties with highly-personalized service… because every situation has unique requirements. Every project has its own challenges. Every community has distinct goals. And we have the experience to recognize the differences. We design and engineer each project with individual goals in mind. Yours.
