These systems can also be used to stop an excavator before the pipeline is damaged. The cost to install these systems during initial construction varies significantly, depending on pipeline length, configuration, and the pipeline control system. These systems can also be installed on existing pipelines by plowing or trenching to install the cable. Alternately, applying concrete coating around the pipe circumference can protect it from excavation activities. For new construction, the costs of this mitigation option vary widely, depending on pipe diameter, terrain, availability of concrete, etc.
Costs range from several dollars to tens of dollars per linear foot.
Additional pipe wall. For small-diameter pipelines, a thicker or additional pipe wall can be provided at relatively minimal additional cost. Increased pipeline burial depth. For new construction, burying a pipeline deeper can place it out of harm's way, beneath the typical digging depth of many excavation activities. The cost of this approach varies.
