Corcoran Hall will be open for classes Monday, after closing last Tuesday when officials discovered a crack along the concrete of the basement.

The University evacuated the building and brought in engineers and experts to evaluate the building to determine a cause of the crack. Experts collected soil samples, but Senior Associate Vice President of Operations Alicia Knight said Thursday that they still had not determined a cause.

According to a campus alert, experts determined the building was safe for use, but will continue to monitor the crack to ensure the building remains safe for occupants.

Experts will begin to set plans to repair the crack Monday, which the University warned could lead to noise in the building, adding that classes could be relocated should repairs get too loud.

Corcoran Hall has been under construction for the past year to prepare for the GW Museum, which will be built close to the aging science building to comply with requests from the city’s Historic Preservation Society that the museum not overshadow the Woodhull House.
