When you were younger, playing the game hide-and-seek was fun and a great way to just be a kid. When you are looking for a 36-inch pipe with a 42-inch casting and a 30-inch pipe with a 36-inch casting that is causing a short on active fuel lines at a depth of more than 20 feet, it really isn’t that fun of a game. That is what Price Gregory International was faced with on a site in Lisle, IL.
For excavation projects requiring manned entry, shielding and shoring trench walls is a major cost. Material and labor prices escalate as excavations cover more area and become deeper. On many large projects -- especially long runs of large-diameter pipe installation -- slide rail systems have become the preferred method of preventing the collapse of trench walls.
