Associated Regional and University Pathologists, Inc., or ARUP, provides research and testing services to clinics, hospitals, and government organizations. The corporate headquarters is spread across 400,000 square feet in four different structures at the Research Park complex of Salt Lake City. The first building, built in 1989, contains research laboratories and administrative office space. The three other buildings were constructed, one at a time, as the company expanded over the years. The steel framing and the brick and glass exterior were designed and constructed with the latest technology to maintain the same look and feel throughout all the structures.
