St. James Condominium Tower, Philadelphia, USA
Self-Climbing Steel Formwork
for Perfect Reinforced Concrete Facade Cast In-Situ
With a total height of 156 m, the St. James complex is regarded as the first apartment highrise building in the city of Philadelphia. The 48-storey tower has over 300 apartments which can be purchased or rented.
The structure is comprised of a core for the stairwells and elevator shafts, floor slabs and a complicated facade. In-situ casting was used throughout the project. As had been the case many times previously, Carson Concrete decided in favour of PERI formwork technology. Using the ACS self-climbing system, VARIO GT 24 girder wall formwork, SKYDECK aluminium panel slab formwork and special steel formwork for the complex facade, PERI provided a cost-effective formwork concept. The experienced construction team was able to finish the project ahead of schedule as well as realising the demanding quality standards.
By using specially designed steel formwork elements, PERI was able to meet the high demands regarding an economical realization of the project and ensuring a high quality facade surface finish. The foldable elements were mounted to the external ACS-R climbing units and hydraulically climbed from floor to floor. This resulted in considerable timesavings during shuttering and striking as well as providing urgently needed crane capacity.

“The results which we achieved using the steel formwork on the facade are unbelievable! Through the foldable elements attached to the climbing units, we could significantly reduce our labour costs. This was also a major factor in helping us maintain construction schedules.”
