摘要：One of the issues from land subsidence consequences is tilting on building. At the places where differential subsidence is existed we might literally see the building tilted. Jakarta is a mega city in Indonesia where significant land subsidence (e.g. 1-26 centimeter per year) is happening today. Issue of tilting on buildings due to land subsidence in Jakarta has been raisin. There is one high-rise building namely Menara Saidah which is judging to be tilting. As consequences the building has been abandoned. The building in the office of House of Representative is also being rumored to be tilting. Judging and rumored are not scientific, we need real measurements. There are more than two hundreds of high-rise buildings established in Jakarta city. We use the Terrestrial Laser Scanner survey to investigate the issue of high-rise building. This technology has capability to create 3D object with milimeter accuracy. Tilting on the building can be seen simply by their verticality. We have chosen several high-rise buildings to accurately measure, especially where large subsidence is there. This paper is a highlight on the investigation. As the conclusion we found the verticality of investigated buildings are still within the tolerance.
