ZEENA TOWER, BEIRUT, LEBANON

Zeena Tower is a mixed-use building located at the heart of a developing neighbourhood in Beirut. CCL was commissioned to undertake the structural design and execution of the architectural facade. The facade panels are made from Ultra High Performance Concrete (UHPC). The strength of the panels is more than twice that of normal concrete with a compressive strength of >160 MPa.

CHALLENGE

CCL’s objective was to create the architectural facade of the 20-storey Zeena Tower. The architectural design of the building features a 100-metre-high ‘urban filter’ that overlooks the expressway that runs alongside the Beirut River. On the other side of the building, suspended gardens help create a smooth transition into a calm, green neighbourhood.

SOLUTION

CCL calculated the minimum thickness of the concrete to be able to create 4×6 panels at 8cm depth due to the concrete’s strength. The panels were manufactured by CCL at its purpose-built UHPC factory in Lebanon. CCL also designed and manufactured the specialist fixings and the panel moulds. Post-tensioned slabs throughout the building were also designed, supplied and installed by CCL.

BENEFITS

  • 50% less concrete is used compared to conventional methods.
  • No need for any traditional reinforcement, which reduces costs and CO2 emissions.
  • High post-cracking tensile strength, so it is long-lasting with minimal maintenance.
