The Scenario
The job was fairly standard with respect to challenges.  The steam line would run mostly in a straight line.  Additionally, there would be no space or equipment restraints on the project.  The contractor would be reliant upon the shoring system being installed prior to being able to commence with its work on the project.


The Solution
Casey Willett met with the contractor to review basic job expectations.  The contractor was extremely adept at this type of excavation and the equipment needed.  The contractor needed flexibility with respect to the equipment and when it would be delivered.  The contractor was unsure of the exact placement of the crossing utilities and would need to adapt the shoring system as a function of the crossing utilities.  These demands fit well with Coble Trench Safety's vast branch inventory of assorted shoring equipment designed for any job.  The contractor had the flexibility of Coble Trench Safety's inventory as the job unveiled the requisite shoring system, and coupled with Coble Trench Safety's ability to deliver equipment in a timely, ready-to-use manner the contractor need not worry about the trench safety needs for the project.  The contractor ended up using hydraulic vertical shores, steel trench shields and steel plate during the course of the project.

The steel trench shields were used for the linear runs, while finn form and hydraulic vertical shores were used to fill the gaps presented by the crossing utilities.  Hydraulic vertical shores allow for flexible cylinder placement, so long as it meet OSHA standards and/or manufacturers tabulated data, to encompass the crossing utility.
