Project Description
The Bachman Interceptor Project was one of the first major microtunnelling projects in Dallas. The project consisted of a 1200mm tunnel that was 8300m in length. The ground conditions included soft rock, running sands/gravel and clayey sands/sandy clay. Due to the proximity of the tunnel to the lake, high groundwater was present throughout excavation.
