| Work Detail | A stretch of unusually hard rock inside a mountain near Cameron Pass has slowed a tunneling project aimed at shoring up Fort Collins’ water supply. Progress on a 760-foot tunnel that will carry Michigan Ditch water to the city-owned Joe Wright Reservoir was stopped as of Thursday. Crews are waiting for the arrival of replacement parts for the cutting head of a tunnel boring machine, or TBM, that was custom built for the project, said Owen Randall, chief engineer for Fort Collins Utilities. Bearings on cutting disks on the rotating head have repeatedly burned out while dealing with a wall of pegmatite, a type of granite that can have various minerals and be exceptionally hard, Randall said. |
