Structural Services


The Structural Services Department provides design services for the development of new structures as well as for rehabilitation of existing structures. We have a wide range of clients including state agencies, municipalities, contractors, design-build entities, commercial and private developers, and institutional (K-12 and higher education).

NDM’s experience as it relates to structural engineering and design has been built on a long history of successful projects with a variety of complexity. Also, our construction experience allows us to develop difficult projects utilizing not only a technical thought process but also a practical approach to constructability and cost.
