Guilford County Detention Center
This was a mass excavation project for the $115 million Guilford County Detention Center that opened in 2012. The structure was an eight-story concrete jail that contained approximately 400,000 square feet of space. The challenges faced with this project included an underground tunnel to the existing jail and poor subsurface conditions associated with a former lake. Thousands of cubic yards of unsuitable material was removed and replaced with granular fill material.
