The Burj Khalifa is part of a larger development plan that includes 30,000 homes, nine hotels, 3.0 hectares of parkland, 19 residential towers, the Dubai Mall, and a 30-acre manufactured lake. It will also be the tallest building in the world.
The decision to build the Burj Khalifa was predicated on the government’s aim to diversify the economy away from oil and toward services and tourism. Officials believe it will attract more international attention and, thus, investment. Sheikh Mohammed bin Rashid Al Maktoum wanted to put Dubai on the map with something sensational.
The Burj Khalifa is a skyscraper built by Samsung Engineering & Production in partnership with Besix from Belgium and Arabtec from the UAE. Turner is the Project Manager for the project, and under UAE law, Hyder Consulting is responsible for the tower’s performance.
The Building of the Burj Khalifa
The Burj Khalifa is a large concrete and steel structure located in Dubai. It took 22 million person-hours to build and required 330,000 m3 of concrete and 55,000 tons of reinforcing steel. The foundations were built using high-density, low-permeability concrete, and a cathodic protection system. It helps to mitigate the negative impacts of corrosive substances in local groundwater. The above-ground structure is mild steel and has pressurized; air-conditioned shelters positioned every 35 floors. Putzmeister developed a new high-pressure concrete trailer pump for this project, the BSA 14000 SHP-D.
Each batch of concrete used is tested to guarantee it can sustain a specified pressure. A cathodic protection system is employed to mitigate the negative impacts of corrosive substances in local groundwater. The Burj Khalifa is a large commercial building in the Persian Gulf. CTLGroup and SOM conducted creep and shrinkage tests to ensure the concrete could withstand the high temperatures and pressures of the area. Ice is added to the mixture in summer, and a concrete mix medication is used to keep it from cracking.
The superstructure is supported by massive reinforced concrete and drilled concrete piles. The podium is the foundation for anchoring the tower to the ground, providing grade access to three building levels. The glass entry pavilion is built with a suspended cable-net structure, connecting the corporate Suites on Level B1 and Concourse, the Burj Khalifa House on the ground level, and the Armani Hotel on Stage 1.
