Linde has laid dozens of miles of natural gas pipelines in the Marcellus region of Pennsylvania. Pipeline construction resembles a moving assembly line. Each length, or spread of pipeline, is built by a specialized work crew, each with its own set of duties. These are outlined below. As each crew completes its work, the next crew will move into position to complete its section of the construction project. A construction spread may be several miles in length, with the front of the spread clearing the right-of-way and the back of the spread restoring the right-of-way.
