AE2S designed and oversaw construction of a 70.5-inch diameter bypass pipeline that was microtunneled through the mountain adjacent to the Deer Creek Dam. The pipeline was welded steel and approximately 900 feet long. The microtunneling machine exited into Deer Creek Reservoir while the reservoir was full and was recovered while submerged. The pipeline tunneled through an exit portal that was constructed by diving construction crews. Special consideration was given to pressurizing the pipe and applying a bentonite slurry along the outside of the pipe to prepare it for the conditions that would be present after being subjected to water pressure from the reservoir. The pipeline will be connected to existing penstocks on the downstream side of Deer Creek Dam allowing water to flow into the Provo River while the existing intake can be taken offline. The project featured a Construction Manager/General Contractor (CM/GC) method of delivery to mitigate as much risk as possible and to provide contractor input during design.
