Duplantis Design Group (DDG)

In 1997, DDG began as a small, civil engineering firm based in Thibodaux, Louisiana. From the very beginning, we believed that exceeding our clients’ expectations was the only way to achieve long-term success. Since our founding, our unwavering commitment to client service excellence has allowed us to grow into a multi-disciplinary regional firm with over 150 full-time employees and 8 offices across South Louisiana, Alabama, Texas, Mississippi – Thibodaux (headquarters), Covington, Baton Rouge, New Orleans, Lafayette, Mobile, Mississippi, and Houston.

Originally offering services in civil engineering, we have methodically expanded our services to also include architecture, coastal and water resources engineering, landscape architecture, environmental and regulatory consulting, surveying, transportation engineering, funding advisory, structural engineering, and project management. Through the hiring of key staff and strategic partnerships with specialty firms, DDG has proven the capability to deliver a wide range of services and support.
