Engineering, Architecture & Design Services


In many ways our company has come a long way. From our humble beginnings in 1955 we have grown into the regional multi-disciplined firm of over 200 employees that we are today.

In 1955, Robert S. Over, Lewis L. Gwin and Paul I. Detwiler got together and decided to form Gwin Engineers, Inc., with a vision that with hard work, strong technical skills, and a culture of integrity they could make something special. So with these fundamental principles and a small rented office at the corner of 11th Street and 13th Ave. in Altoona the seeds were planted.

During the 1960’s we experienced strong and steady growth and became well known as a transportation design firm. In 1970, we dedicated our efforts to diversifying our services to include water/wastewater engineering, surveying and mapping from our current location. Shortly after, and with an eye of further growth and a desire to establish a new stronger identity that portrayed a larger, diverse, and dynamic firm we changed our name to The EADS Group.

As our growth continued and we sought to strengthen both our market diversity and our geographic reach we focused on acquisitions. In 1977 we acquired the former Neilan Engineers, Inc. with offices in Somerset and North Versailles, PA. This acquisition further strengthened our growing presence as municipal engineers specializing in water and wastewater issues by adding over 40 municipalities and municipal authorities to our growing client list.

In 1980 we continued our quest to expand our services and reach with the acquisition of General Engineering Associates and Trico Engineers with offices in Clarion and DuBois. These firms were well known throughout northwestern Pennsylvania for the experience in mining engineering and surveying.

In 1989 we acquired J. Richard Ross Architects and became a truly mutli-disciplined firm, now offering a complete array of engineering and architectural services including transportation, water/wastewater, environmental, mining/geotechnical, surveying, mapping, architecture, and building systems.

In 1994 we incorporated The EADS Group, Inc, a holding company and slowly started shedding our separate corporate identities while working toward the creation of a new vibrant consolidated company.

Our growth continued and in 1994 we opened an office in Cumberland Maryland offering engineering and architectural services to a yet, larger geographic area. Our growth continues today with opening of office in Johnstown in 2007 and in Lewistown in 2011 and we have become a perennial honoree as one of Engineering News Records Top 500 firms in the country.

Through our continued commitment to those early principles of hard work, integrity, quality, and dedicated client service we have grown from a small Altoona transportation engineering firm to a large regional, seven office firm offering a wide and comprehensive array of services and serving clients, not only in western Pennsylvania but throughout the country.

Please join us in celebrating our 60 years of success and service. We pride ourselves not only in what we’ve become, but as importantly who we were and our path to success. We are blessed with truly professional and dedicated employees who take great pride in what they do, the contributions they make and the communities they serve.
