It’s not clear what role Walter Scott plays in Tetrad and the Innovation Campus. At an event there last fall, Perlman thanked Tetrad’s “key leaders” — naming attendees Walter Scott, David Scott and Wiegert specifically. Perlman said in an interview he had not known the senior Scott was involved with Tetrad when the company was hired.

University records show that Tetrad affiliates began their work on the cancer center and Baxter Arena several months before the development corporations were even formed.

Records provided to The World-Herald show that UNMC, not the development corporation, first awarded cancer center work to a Tetrad affiliate, S2W. In a series of letters, UNMC and its partner, the Nebraska Medical Center, agreed to pay the affiliate more than $900,000 for a year of development work on the cancer center starting in March 2012.

For the arena project, the Board of Regents initially approved a plan for S2W, the Tetrad affiliate, to split most of the costs with Heritage Services, a private, nonprofit group that coordinates civic donations from Omaha’s philanthropists. Scott is a founder and chairman of that group, and Hawks sits on its board of directors.

The university intended to lease the arena back from S2W with plans to purchase it, according to board documents.
