SEH and Yaggy Colby Associates Announce Intent to Merge Companies

February 18, 2014

Short Elliott Hendrickson Inc. (SEH®) and Yaggy Colby Associates (Yaggy Colby) announce that the companies have signed a Letter of Intent to merge.

SEH and Yaggy Colby share a common goal to deliver the highest quality engineering and architectural design services. The merger will further SEH's core purpose of Building a Better World for All of Us® and allow both companies to provide additional specialty services to benefit their public and private clients. Because SEH and Yaggy Colby share similar core values, the companies will continue to be vested and involved in the communities where we office, live and work.

The pending merger is conditional based on final transactions associated with a merger. The merger is expected to be complete by June 1, 2014. Following the official merger, Yaggy Colby will operate as a division of SEH. After a one-year integration period, both companies will operate as SEH. 

Together, We’re Better Able to Serve our Clients

In addition to offering a number of services in common, the merger allows the companies to offer additional services to their clients. SEH provides Yaggy Colby clients architectural design, airport planning and design, geotechnical engineering, flood risk management and mining services as well as a host of other specialty services.

Yaggy Colby provides SEH with the ability to offer right-of-way services and a broader bandwidth of land development services. In addition, the merger will provide SEH with a stronger geographic reach for clients located in southern Minnesota, north central Iowa and southeastern Wisconsin.
