Slide Rail Overcomes Obstacles

excavation site
The excavation site had very limited access and many surrounding obstacles to contend with, including: a loading bay dock directly along one side and newly installed electrical banks just a few feet on the other side of the excavation.
T & B's tank installation
For T & B's tank installation project, an unobstructed opening of more than 55 feet was made possible utilizing Efficiency's unique Parallel Beam cross-trench support design.
ClearSpan waler beams
- After the ClearSpan waler beams were secured in the integrated brackets that slide down the outside face of the linear posts; the three parallel beam-spreader assemblies were removed for the tank set. The result was an unobstructed pit that was 56 feet long and was able to accommodate the 47 foot long tank.
Shoring
The tank was set with a crane and backfilled with stone, while the slide rail components were pulled incrementally from the ground as the backfill progressed.

On a busy hospital campus such as St. Francis, a project such as this was not going to be easy or routine.  The excavation site was located about 6 feet from the hospital, and had very limited access and many surrounding obstacles to contend with, including: a loading bay dock directly along one side that had to stay open throughout the excavating and installation process, and newly installed electrical banks just a few feet on the other side of the excavation site.  Excavators and other equipment could only access the site from two sides.

Shoring the excavation to T & B's strict safety standards was going to be a huge challenge.
