Construction crews are replacing the gutter around the building and the outside architectural stones -- called coping stones -- that line the top of the building, said Ira Simon, a Carolina Dining Services administrator.
When the roof project initially began in fall 2001, workers removed broken slate to repair the leaks on the roof and discovered that water had seeped in to the rubber facing that holds the gutter to the coping stones, he said.
More stones were found that were damaged or broken when the gutter was removed, he said.
Simon said 65 percent of the 4-foot stones were cracked and needed to be replaced.
Subcontracted crews from Western Waterproofing of America are replacing the gutter and the stones.
Although the project is important for the building's maintenance, Simon said, the work is "purely cosmetic" to help maintain the architectural look of the building.
The gutter removal started in May and was supposed to have been finished July 15.
Because of a processing delay by the stone company, it took six weeks for the stones to be delivered.
Work resumed once the stones arrived at the beginning of September, Simon said.
