Site Agent, Pretorius states that RMD Kwikform played a critical role in the project’s success. The Rapidshor used for shoring to the working platform for erection of the Conical dome provided an easy to erect, labour-saving, shoring solution with an 80kN leg-load capacity. In addition the 8-holed lugs on standards allowed for skewed bracing without a reduction in load capacity, allowing for a stable integrated circular arrangement around the tower section.

Pretorius deems the Superslim Soldiers that were used as Primary bearers in the revolutionary Conical Formwork Design as “in a class of its own” and a first of its kind. He believes that the Superslim solution played a critical role in assuring Ultimate Dynamic a competitive advantage in recently securing similar projects.

Duration of Project: 18 months

Equipment Used: RMD Megatruss Traffic Portal supported by Megashor Towers

Benefits of Solution Provided: To fast track the construction of the Cornubia bridge deck between two freeway lanes (N2 NBC/SBC) with limited space in between (median).
