The Project
Impressions from the project process
Two 175 m high piers at a distance of 472 m from each other, take the loads of this cable stay construction which connects both sides of the Cooper River.
On artificial islands in the Cooper River, the pylons rose steadily upwards in regular weekly cycles using PERI self-climbing technology and PERI VARIO girder wall formwork.
With the ACS self-climbing system and VARIO GT 24 girder wall formwork, the high requirements on the concrete surfaces and dimensional accuracy could be fulfilled.
The ACS self-climbing system lifting 4 working levels together with the formwork without the use of a crane: concreting platform, shuttering and striking level, platform for the hydraulics and climbing operations, and the finishing platform for dismantling the climbing shoes and anchor cones.
The two pylons of the Arthur Ravenel Jr. Bridge form the main load carrying members for over 472 metres of cable stay bridge decking.
Up to the change in inclination of the pylon legs, a total of 11 cycles had to be concreted, each with heights of 4.15 m.

Senior Site Manager
Early experiences and the excellent working relationship with the PERI engineers made it an easy decision when it came to our choice of formwork supplier. With the PERI solution we have a formwork system on the site that enables us to work quickly and at a high quality.
