Complex Shoring Solution
What do you call a job that requires four different pipe jacking pits to install a new 72-inch sanitary sewer pipe? While that may sound like a standard job, the reality was much different.
It required excavations that ranged from 20-feet deep to 32-feet deep, had an active 21-inch sanitary sewer line running through one of the pits, a pond directly next to another of the pits, a creek less than 12-feet away, had a mix of sticky clay soil and running sand, there was an apartment building nearby, and also had a highly traveled road 15-feet away.
But if you are Lowe Construction, you would call it a successful job.
Lowe Construction contacted Pro-Tec Equipment early-on in the process to design a plan to safely and efficiently protect their workers. According to Joshua Thorne, Pro-Tec Equipment’s slide rail manager, “with the mix of bad soil conditions, the proximity to a building and a road, and the overall scope of the project, I was confident that the Pro-Tec Slide Rail System would be able to get the job done for Lowe.”
The Pro-Tec Equipment Slide Rail System is a dig and push-style system. With its modular, flexible design, the system can comply with a wide variety of shapes and sizes. The Pro-Tec Slide Rail Shoring System is installed from the top down and removed from the bottom up, minimizing size of excavations, soil disturbances and restoration time and cost. The installation is done with low vibration, providing soil support for excavations, adjacent structures and existing utilities.
“The original plans called for a beam and lag system,” said Scott Bazinet, president of Lowe Construction. “We asked the engineers if we could use the Pro-Tec Slide Rail System instead of the beam and lag. They were happy to allow it.”
The project, Saddleback Sanitary, located in Grand Rapids, MI, called for a low-vibration system, since all the work would be taking place in close proximity to multiple apartment buildings. “In past projects when we used the slide rail system, we were able to push the post in place with our excavator bucket,” said Scott. “Since we were so close to the apartment buildings, we had to take it a step further and pre-drill the post holes.”
