Introduction
When an underground utility line unintentionally intersects with another, the results can be disastrous. This is known as a cross bore, and dangerous consequences can happen instantly — or occur long after a project is completed. Either way, the safety of your crew and the people above these buried utilities depend on horizontal drilling contractors taking measures to avoid making a cross bore.
Proper upfront planning and taking preventive measures during the installation is key to helping avoid cross bores. Learn the steps every
horizontal directional drilling crew should follow to avoid making a cross bore. This paper covers planning best practices and tools that
can assist with bore planning, potholing methods, how to properly calibrate a drill head transmitter with a locator, reliable ways to locate
sewer lines and tips for reaming.
