In 1983 John J. Roshek, a buyer for Siegel and Cooper of Chicago; his brother Frank H. Roshek, a traveling salesman for a Philadelphia wholesale house; and A.E. Rubash, a dress good buyer for Denneck Yetter of Cedar Rapids, established a dry goods business in Dubuque. The Roshek, Rubash & Company located in the Horr Building at 556 Main. Rubash sold out and a Mr. Aimann joined the business. On April 6, 1896 the firm’s name became Roshek, Aimann & Company.

After Rosheks moved from downtown to the west end, nearly two years later, Edward Sheppley of W.S. Sheppley and Company announced the purchase of the building with plans to offer office space on upper floors and a potential department store in the near future. The structure was renamed the Dubuque Building, and nearly $5 million in renovation was begun.


In 1984, W.S. Sheppley and Company filed for protection under Chapter 11 bankruptcy proceedings. In 1986, the Dubuque Building was sold to its largest tenant, CyCare Systems, Inc. for $5.7 million. The building was then 65 percent occupied with CyCare using 40 percent of that space.


In January 2000, CyCare Plaza was renamed the Dubuque Building following the purchase of CyCare by HBO & Co. and its merger with McKesson Corporation. On January 25, 2008 McKesson, a Fortune 20 health-care services company with revenues of $93 billion, announced that it would reduce its Dubuque operation and sell the building.


When IBM announced its choice of Dubuque as the location if its new global delivery center in Fall 2009, the decision was influenced by the sustainability initiative that Dubuque began in 2006 that matches well with the IBM corporate philosophy. Another factor was the strong public/private partnerships that exist in Dubuque.


Together with Dubuque Initiatives, a nonprofit development company dedicated to downtown revitalization, it was decided to renovate the building according to the United States Green Building Council’s LEED (Leadership in Energy and Environmental Design) green building rating system. Achieving LEED certification requires the use of green building materials; noted improvements in energy efficiency; and the reduction, recycling, and reuse of all waste materials. The decision to use an existing structure, rather than build new, is one of the most sustainable choices that can be made on a large-scale project.


Rehabilitation started in January 2009 and was completed in 2010. The Roshek Redevelopment is the largest and most formidable sustainable project ever to take place in the City of Dubuque. From its inception, it has been fast paced and challenging, with only five months separating the start of the project and IBM’s occupation of the multi-tenant building. The project called for the complete overhaul of over 250,000 square feet, including nine floors above grade, a lower level, and a sub-basement.
