IOWA CITY, Iowa (AP) — More than a year after its completion, several companies who helped build the University of Iowa’s new indoor football practice facility say they’re still owed money for their work. Four subcontractors have filed claims in state court in recent weeks alleging the project’s general manager, the Samuels Group, Inc. of Wausau, Wis., owes them a total of more than $1.5 million.

In a separate federal lawsuit, the Samuels Group argues that it should not have to pay some of the companies because they delivered and installed metal panels that did not initially meet specifications. State and federal judges are expected to sort out the claims in the coming months.

The new practice facility has been praised by the football team, which was competing in the Outback Bowl on Wednesday.
