OMAHA, Neb. (AP) — A $1.25 million lawsuit has been filed in U.S. District Court in Omaha over the construction of the Omaha National Cemetery.

Seedorff Masonry Inc. of Strawberry Point, Iowa, has sued a Chicago construction company and the project’s insurer over unpaid bills.

The lawsuit says Archer Western Construction entered into a contract in 2014 with the Department of Veterans Affairs to furnish materials and perform the labor for the cemetery. An attorney for Seedorff, a subcontractor on the project, says Seedorff provided nearly $3.2 million in labor and materials, but Archer has paid the company only $1.9 million.

In the lawsuit filed Monday, Seedorff alleges Archer and Travelers Casualty and Surety Company of America owe Seedorff $1.25 million, plus interest.

The cemetery opened in 2016.
