RSD celebrates 25 years of service in the NYC metropolitan and tri-state area. In those years, our firm has completed hundreds of projects and transformed into a truly diverse practice covering the design of many high and mid-rise commercial and residential structures, academic and institutional buildings and special projects of considerable or even unique complexity. We look forward to our new association with Vertika Structural Engineers, LLC and are certain our clients will greatly profit form the magnified resources, knowledge and experience these two firms will bring to bear on any individual project.
