This paper summarizes the structural concept and design of the twin 303-meter high “Indonesia-1" supertall building currently under construction in Jakarta. The first tower is a 63-story office building, and the second is 59-story, on top of the seven-level basement structure. The lateral resisting system of the towers is RC core-wall and outrigger, and composite floor system - with concrete slab, metal deck, and steel beams - is used for the gravity resisting system. Since the lateral system is outside the scope of the prescriptive system in the Indonesian Seismic Design Code, Modal Pushover Analysis (MPA) combined with Non-linear Response History Analysis (NLRHA) had demonstrated acceptability to the Jakarta building department and its peer review panel. Some challenges in conducting Performance-based Seismic Design (PBSD) are highlighted. In order to speed up construction, which is a critical factor in supertall building construction, erection columns are installed in the RC columns and CSPCM (Core Structure Preceding Construction Method) is applied. Consistently, the design must account for the associated construction sequence.
