Strategically positioned right in the heart of the Jakarta CBD, this project development is located between the Grand Hyatt Hotel, EX-Centre, and the Japanese Embassy. 

The project was constructed with a design-build method, where SsangYong Engineering Construction was the main contractor who appointed Davy Sukamta & Partners for the structural and foundation design. It has a total floor area of 200,000 square metres. The Plaza Indonesia Extension project consists of a 48-storey Keraton at the Plaza Residence, a prestigious 42-storey office building, a podium block for a shopping centre and a 5-level basement for parking space. 

 

The project applied several state-of-practices in its design. It is the first building in Indonesia designed for a 2475-year earthquake following the IBC-2003 requirements as per the client’s brief, instead of the 475-year criteria as stipulated in the Indonesian code. Studies on Probalistic Seismic Hazard Analysis and Site-Specific Response Analysis have been conducted for this purpose, and the structure has been designed using higher Peak Ground Acceleration than what the code demands. The foundation system uses bored-piles up to 70 metres deep with a record allowable load of 1,500 tons, tested by the Osterberg Cell method, where no counterweight was needed. The force was applied through jacks installed in the bored piles.

 

The basement has an excavation depth of 17 metres, and was designed for top-down construction, whereupon completion of the mat foundation, the superstructure reached Level-10, saving a massive 11 months of construction time. This milestone was achieved in October 2007. The total construction time was 33 months, while the retail building was completed in 30 months. The design and build system proved to save time and significant cost for the project.
