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, sued Archer Western Construction LLC, of Chicago, and Travelers Casualty and Surety Company of America of New York City.

On Sept. 3, 2014, Archer entered into a contract with the Department of Veterans Affairs to furnish the materials and perform the labor for the cemetery. Travelers insured the project.

An attorney for Seedorff, a subcontractor on the project, said the company provided $3,163,947 in labor and materials, but Archer only has paid the company $1,908,037.

In the complaint filed Monday, attorney Mark Hudson alleges Archer and Travelers owe Seedorff $1,255,910, plus interest.

The cemetery opened in 2016.
