Green International Inc.

Green International Affiliates, Inc. (Green) is a multi-disciplined civil and structural engineering firm headquartered in Westford, Massachusetts. Originally formed in 1954 by founder Sam Green as a branch office of its parent company, Green International, in Pennsylvania, Green consolidated operations in the Boston area in the 1980’s. During the two decades that followed, Green maintained a solid position in the New England transportation and water resources industries, steadfastly serving local state agencies in the design of their infrastructure improvement projects. These early years laid the foundation for the growth that was soon to follow.

Every day, people drive on the highway, bike over a bridge, or play ball in the park – using infrastructure designed by Green in their daily lives. We have a unique opportunity to create designs that shape the world we live in, and we do it with pride.

Engineering is our passion, and we love to see the positive impact that our designs have on each community we work with. When you choose Green as your engineering firm, you’ll get a custom design that fits your vision and goals.
