“We were in need of a TBM operator for our project, and Smith & Long came through! Even with short notice Smith and Long dispatched for us an experienced TBM operator who jumped right in and banged off two 400ft pipejack tunnels for us. Many thanks and looking forward to working with Smith and Long again”
