Al Hamra Tower, Kuwait City, Kuwait
Winding elegantly upwards with PERI climbing formwork
With the Al Hamra Tower in Kuwait City, a new landmark was created in the Persian Gulf with the highly visible sculpture rising to an impressive height of 412 metres. The renowned American team of architects Skidmore, Owings and Merrill LLP (SOM) designed a luxurious office building by which the building structure winds its way upwards in a counter-clockwise direction like that of a spiral.
For the forming of the vertical core walls, the ACS self-climbing technology was combined with TRIO panel formwork. On the external facades, the RCS Climbing Protection Panel provided the necessary protection for the construction of the floor slabs as well as the edge beams. In the process, the RCS climbing rails were fixed by means of slab shoes to the available slab edge so that the units were permanently connected to the building also during the climbing procedure. Mobile RCS self-climbing devices removed the need of a crane. The floor slabs were formed using SKYDECK, the lightweight aluminium panels ensured fast and fatigue-free assembly for site personnel.
Due to the spiral-shaped building design, the southern external core and retention walls not only underwent a change to their length and position, they were also partly twisted. For these areas, climbing units comprising of the SKS single-sided, retractable climbing formwork system and the flexible VARIO GT 24 girder wall formwork were formed. For moving the crane-climbed formwork, a crane spreader beam made of PERI system components was used. This was designed to guarantee that each unit could be always attached to the crane using the respective centre of gravity in spite of

“The PERI systems were easily adapted to suit the constantly changing geometry of the Al Hamra Towers. The SKS 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.”
