Project Description

Located on the corniche of Sharjah, U.A.E., the Crescent Tower was built in 1996 as an office building. Today, the 22-story building houses major oil and gas company offices. Before modernization of the building’s previous elevators, tenants were experiencing long wait times in the morning during peak travel times. Additionally, the elevators did not conform to the latest safety standards, and therefore had to be updated. One of the main obstacles was the building structure itself. In order to transport the lift material, it had to be lifted to a height of 100 m to the top of the building with a mobile crane. The ultimate result offered safe and reliable elevators and a significant improvement in traffic performance.
