Case Study: Concrete Repairs Inside a Dam Spillway
The PROBLEM
The main problem on this project was the access into and on top of the spillway training walls for concrete repair work. Scaffolding was not only an expensive option but a cumbersome one, especially during a heavy rain event. The client, inexperienced with rope access, needed to determine the most effective solution for access and work.
The SOLUTION
Collaborating with the client, it was decided that it would be better to do half of the work via a crane & man basket and half with rope access. The first option is extremely expensive and restrictive as you can only have two people working in a
small area at once. With rope access, we were able to have anywhere between 1-8 (these numbers could be greater if more tools were accessible) technicians all working at any one time.

Right Photo: This photo demonstrates the larger work area for rope access technicians. Workers have the ability to transfer from rope to rope with ease and efficiency to expand their work area quickly.
The RESULTS
After a few shifts, it was clear that the rope access team was more efficient due to their access. They were able to move along the work area quicker than the man basket team. And, had more flexibility. We managed to get the entire project completed on time even with work flow stoppage due to weather and other contractors. The client saw the true value in the production increase using rope access, and decided to use rope access at the preferred access method to complete additional work.
