Our History Shapes Our Competitive Advantage

Woolpert is one of very few firms that has been in business for more than a century. Charlton Putnam and Ralph L. Woolpert founded the engineering and surveying firm in Dayton, Ohio, in 1911. The Great Dayton Flood of 1913 resulted in one of the greatest private-public works of all time and created countless opportunities for Woolpert to perform surveying and engineering work for the area’s new housing developments.

Through the decades, Woolpert has consistently added service offerings to an expanding client base. As we’ve grown, we’ve added environmental and sanitary engineering, city and regional planning, photogrammetry, airport planning and design, traffic engineering, landscape architecture, environmental sciences, architecture and geospatial services to our repertoire.

In 2019, Woolpert acquired Waller, Todd & Sadler Architects, an architecture firm in Virginia Beach, Va. This addition to our corporate family bolsters our design and planning capabilities while providing our clients with an impeccable reputation for quality design and excellence in customer service.

Today, Woolpert is a national architecture, engineering and geospatial (AEG) firm of more than 850 talented professionals. Our headquarters remain in Dayton, and we serve clients on a local, regional, national and international basis from over 25 offices. Woolpert’s ability to continually adapt to changing times and provide an increasing range of professional services is the basis for our service-oriented culture.

We started as a local engineering and surveying company over 100 years ago. Today, we are a worldwide leader in AEG services and an ENR top design firms. Woolpert is moving forward—with forward thinking.
