The PERI systems were easily adapted to suit the constantly changing geometry of the Al Hamra Towers. The SCS and ACS climbing systems were easy to handle and featured high safety standards. In addition, the RCS Climbing Protection Panel provided safe working conditions. With SKYDECK, the slabs could easily be formed by hand even during strong winds which reduced crane requirements. Altogether, the PERI systems made it possible to have an 8-day cycle and have greatly contributed to the success of the Al Hamra project.
