There are several steps to pipeline construction, which result in crews working for about 5 days in each area, depending on local conditions. Crews will saw cut the pavement, excavate the trench, lower the pipe into place, weld the pipeline segments together, backfill the trench, and install temporary asphalt to repair the road. The contractor then comes back towards the end of the project to install permanent asphalt to repair the road. In locations where new pipes are connected to existing pipes construction periods may take several weeks. Contractors can typically install between 80 to 200 feet of pipeline in a single day
