Central Park Mixed-Use Building in Jakarta

This paper describes challenges during the structural design phase as well as during the construction stage of this mega Central Park Project. Most of the challenges occurred due to the unique architectural design of this mixed-use building, which consists of three 50-floor apartment towers, a 42-floor office tower, a podium mall with 12-floor car park building, a 13-floor hotel building on top of the podium and car park, two layer basement for the entire building complex and a large open space garden at the ground floor. The total floor area is 720,000 square meters. Up to now, this is the largest mixed use project in Indonesia. A series of seismic site response investigation was conducted. The results were then used and combined with other loads which were taken into account in the structural analysis. Wind tunnel test were also performed since the current wind loading code in Indonesia has still not covered cases for tall buildings such as this project. Transfer beams and inclined columns were installed to accommodate some special requirements for the structural frames. Monitoring of building settlements during construction was carried out and the outcomes were then compared with the predicted values obtained as the results of the structural analysis. The construction was started in September 2007. The soft opening ceremony of the mall and the topping off of the whole project was conducted in September 9, 2009 and January 5, 2010 respectively.
