Shaft development rates are a function of diameter and ground conditions. For 8- to 10.5-ft-diameter shafts, which is the vast majority of what SDI does, they can complete a 500- to 800-ft shaft in four to six months. For 12-to 15-ft-diameter shafts, the development rate would be between five and seven months.
