MADISON, Wis. -- Part of the old Ogg Hall dorm at the University of Wisconsin-Madison campus is still standing more than a month after demolition was supposed to be done.

That's because the state of Wisconsin ended its contract with the demolition company, Dore and Associates, of Bay City, Mich. State officials said that the work was behind schedule and unsafe.

UW-Madison architect Dan Okoli said that in one incident a large piece of stone fell from the building and smashed a worker's car.

But company chairman Art Dore said that the work was done safely and on time. He claims the state illegally ended the contract.

The university opened a new Ogg Hall in the fall. The old dorm was scheduled to be torn down by March 31.
