Comparing Horizontal Directional Drilling versus Open Cut

Municipal standards are generally biased to open cut construction. Some deviations to the municipal standards were allowed to permit the HDD method. For example, on open cut projects, the manholes are typically installed during the pipe laying operation. With HDD, long lengths of pipe may be installed in the ground, requiring the manholes to be Get price

Open Cut Trenching

Open cut trenching, the traditional method for excavation, involves excavating a trench to either install or repair existing pipes, conduit, etc. If the open cut trench excavation is located in a non‐pavement area, the excavation can be back-filled with soil and surface vegetation restored by seed or sod. When the open cut trench excavation is located Get price
