Robbins Small Boring Unit Earns Place In Record Books

February 2010 Vol. 65 No. 2

The three crossings were initially designed as a pilot tube microtunneling project using vitrified clay pipe. “The owner has saved over a million dollars on the trenchless section alone over their original cost estimates for pilot tube microtunneling. Because the owner listened to the construction community, they saved both time and money, and kept the dollars local,” said Gonzales.

The crossings form part of the Locust Street Sanitary Improvements Project, No. 6335. Approximately 1.1 miles of gravity sewer are being installed by general contractor Northwest Earthmovers Inc. for project owner Clean Water Services. The 18-inch diameter PVC carrier pipe will increase capacity in the area and stop overflows currently plaguing the system.
