ing buildings; dropping in a box just wasn't going to work," he said. "Also, with the highway and the apartment on each side, we realized we couldn't vibrate in any sheeting or drive-in a lag wall," Snode continued. "So, when we got down to it, really the only thing that would facilitate our need was a dig-and-push shoring sys- tem," he said. "Dig and Push" is a process most commonly associated with installing a Slide Rail System. Slide Rail is installed by sliding steel panels (similar to trench shield sidewalls) into integrated rails on vertical steel posts – an outside slotted rail first, then an open-face rail on the inside – then pushing the panels and posts incrementally down to grade as the pit is dug. Calling for Reinforcements Snode, however, had little experi- ence with Slide Rail Systems. Needing help, he contacted his friend Jeff Riddle at Baker Corp. for some ideas. With over 20 years of shoring experience, Baker Corp. carries a full line of shoring equipment, including: Slide Rail shor- ing, steel and aluminum trench shields, hydraulic shoring, and road plate. "We've worked with SSI many times before, and have a good relationship with the company and with their per- sonnel," said Riddle, Baker Corp.'s Branch Operations Manager. "So after looking at Brian's project parameters, I knew that an Efficiency Produc- tion (manufactured) Slide Rail System would work; maybe the only thing that was going to work." Efficiency Production, a Trinity Shor- ing Products company, offers versatile trench shielding and shoring systems that are designed for safe and cost- effective installation of utility systems and infrastructure improvements. Added Snode, "When Jeff started showing us how Efficiency's Slide Rail System works, and the versatility of the system to change depending on ground conditions, well it was refreshing to see that they had a different shoring option for us," he said. However, it wasn't just the contrac- tor that had to be convinced on the effectiveness of the Slide Rail System. Snode and Riddle also needed to con- vince ODOT that it would work in the difficult site conditions, and meet their safety requirements. "We went over the entire installation and removal process with ODOT; how Slide Rail actually works and how it meets their safety guidelines for underground construc- tion," said Riddle. Slide Rail is considered a positive shoring system. It maintains constant pressure against the sides of the excava- tion and requires no over-digging.
