Efficiency Slide Rail helps contactor
keep Business Operating

Joe Raica Excavating of Fowlerville, Michigan, recently installed a new pre-cast lift station at a beverage manufacturer’s bottling facility in Howell, Michigan, in preparation of construction of a new wastewater treatment plant. In order to keep business undisturbed at the facility, Raica needed a non-traditional shoring system for the excavation.

Contractor caught between a lot and a hard space
The lift station was installed in a very difficult spot, right in the middle of the parking lot next to a set of railroad tracks. Raica needed to keep the excavation as tight as possible so that the delivery trucks and other traffic could move freely, while at the same time, not undermine the integrity of the railroad tracks.

Needing a custom shoring solution, Raica contacted Efficiency Production, Inc. - the country’s leading manufacturer of trench shielding and shoring. Efficiency’s Slide Rail Installer and Sales Manager, Greg Ross, quickly knew that Efficiency Universal Slide Rail System would be perfect for the excavation. “Slide Rail works because it keeps excavations tight and vertical with no loss of dirt or fill,” explains Ross.

“Dig and Push” system reduces over-excavation
Efficiency’s Universal Slide Rail is a component shoring system comprised of steel panels (similar to trench shield sidewalls) and vertical steel posts. The versatile system can be used in a variety of configurations, such as small four-sided pits; large unobstructed working pits of infinite size with Efficiency’s ClearSpan™ System; or in a linear Multi-Bay configuration to install length of pipe over 40 ft.

Slide Rail is installed simultaneously as the trench or pit is excavated by sliding the panels into integrated rails on the posts–either double or triple rails depending on needed depth–then pushing the panels and posts incrementally down to grade as the pit is dug; a process commonly referred to as a “dig and push” system.

First-time user discovers the Efficiency Slide Rail advantage
The pit was excavated in heavy clay soil, which may have been previously fill material. Tight-sheeting was not a shoring option due to the railroad tracks, but that didn’t bother Raica. “On other pump station jobs we’ve worked on, it would take forever to vibrate in sheeting,” says company owner Joe Raica. “This system was just so easy to deal with; it was like a big erector set it went together so easy!”

“The Slide Rail System was installed in a day; and removed in just one day,” explains Raica. “Unlike when you open cut, we didn’t need a lot of stone backfill, and we weren’t throwing dirt around, which saved us time and money. I hadn’t used Slide Rail before, but with the prospect of using it again, we can bid on more pump station or lift station jobs,” adds Raica. “Slide Rail potentially opens up another avenue for our business.”

Raica rented from Efficiency a four-sided, 14 x 14 ft. pit system which allowed them to excavate the pit 24 ft. deep to reach grade where the lift station received an effluent lead (bored from the other side of the parking lot). The entire excavation took up only a small area, and did not interfere with the business’ operation.

This was a major upgrade at the plant, yet the construction did not interfere with business at all,” says Mazen Banat, Project Engineer from Strategic Construction Solutions. “Everything went very well, and there was no stop in production.”

Raica used a CAT 235 Excavator to install the Slide Rail System and the 6 ft. round, pre-cast lift station; plus a CAT 950 Loader, and a CAT D4C bulldozer.

Joe Raica Excavating of Fowlerville, Michigan, was contracted to install a new pre-cast lift station in preparation of construction on a new wastewater treatment plant.	Raica turned to Efficiency Production, Inc. for a custom shoring solution that would keep the excavation as tight as possible so that the plant operations would not be effected, while at the same time, not undermine the integrity of the adjacent railroad tracks.
Tight-sheeting was not a shoring option due to the railroad tracks, but that didn’t bother Raica who used a custom-engineered 4-sided Slide-Rail System from Efficiency Production to shore the 14 x 14 x 24 ft. deep trench.	With Slide Rail, the bored effluent lead could be received into the 24 ft. deep pit by simple lifting up the Slide Rail panel.
