BISMARCK, N.D. (AP) — A Fargo contractor is seeking $1.3 million from North Dakota State University for unforeseen costs in construction of a new classroom building.

Roers Construction says the $29.4 million A. Glenn Hill Center was a complex project that was compounded by pressure on the company to finish it in time for an opening ceremony with politicians and guests from Korea.

Architect Brian Berg says there was nothing unusual about the project and the claim was not submitted in a timely fashion. School officials say they agree with Berg but would be willing to participate in mediation with Roers to avoid a lawsuit.

The state Board of Higher Education on Thursday approved mediation, after discussing it behind closed doors.

The building houses classes for science, technology, engineering and mathematics, or STEM.
