The project was originally scheduled for completion in June and then was pushed back to December.
The delays in the construction work occurred because the work was not meeting standards set forth by the University in its agreement with the sub-contractor in charge of construction, said Don Luse, Union director.
Luse said there are many reasons why the construction has been delayed. One example he cited is the construction of a new set of stairs between the Union and Student Stores. The concrete stairs did not meet the necessary specifications because they were not straight, Luse said.
Workers first attempted to fix the problem without having to destroy the previous work, but now the stairs will have to be demolished.
Luse said there also have been problems with the bricks used in constructing the building. "The brick work was not done to satisfaction," he said.
Additionally, workers found more rock underground than the contractor initially anticipated.
For now, space in the Union is limited because Union officials were counting on the extra spaces in the addition, Luse said. Student organizations that have space now are sharing with one another.
"We feel like we've been able to provide everybody with adequate, if not equal, space," Luse said.
Organizations that reserved rooms in the Union for spring received an e-mail Friday regarding changes resulting from the problems in which Events Planning Coordinator Ryan Donahoe assured groups that they still have reservations, but they might be moved to a new location.
