Rebar cage stabilization can be as simple as securing a cage to concrete anchor blocks using rigid braces, but it can also be extremely complicated and involve the use of internal reinforcement, external steel support frames, multiple levels of guy wires, and even full analysis of the rebar itself. DHC has tackled projects large and small. Over the years, the theory of how rebar cages behave and the best practices on how to brace them has evolved dramatically. DHC senior engineer Robin Ko worked closely with the ASCE CI Temporary Structures Committee in collaborating with the engineering department at George Mason University on the subject. In 2013, they published a guideline of safe practices titled “Rebar Cage Construction and Safety: Best Practices” which helped lay the foundation for the research which continues today.

Such is the evolving world of construction that each time we pick up the phone at DHC, we expect there’s a chance we’ll be asked to do something we’ve never done before, or to support a construction practice or method that is pushing the boundaries of what has been done in the past. It is in our core and culture to support our customers with innovative and creative designs which ensure safety and stability, even when the challenges are overwhelming. When we began designing rebar cage support systems in the late 1990’s...
