The Suitability Analysis of Land Use and Building from BIM to Spatial Detail Plan

Abstract

The development in urban areas will continue to occur, such as the construction of settlements, offices, shops, educational and health facilities, and other supporting facilities. With the development that will always continue to occur in a nation, it will also increase the productivity in its city. The rapid development of urban activities will also followed by high demand for land. This can lead to land conversion. Therefore, it is necessary to use the land to its optimal capacity and manage it wisely in order to produce a quality space that is maintained for its sustainability. Rules and regulations are compiled into a plan in the Guidelines for the Preparation of Detailed Spatial Planning (RDTR). This research conducted in North Gandaria Urban Village because the buildings are divided into three environments, namely densely populated settlements, middle to upper settlements, offices and shops which based on geometrical aspects have various building forms from small to large ratios. Each building has different diverse land and building usages. In this study, land use suitability was identified by manual and digital classification, namely by image interpretation and classifying using the Object Based Image Analysis (OBIA) method on SPOT-7 images which were then superimposed to produce land use maps. In addition, this study utilizes altitude data from LiDAR to complement building spatial data and is processed to BIM. BIM dimensions are made in 3D with Level of Development 100 or equivalent to Level of Details 1 which has a flat roof if converted. From this research resulted suitability of land use and buildings to carry out an analysis related to sustainability and can be used as consideration and input by the policy makers on spatial planning policies. Based on the results of the analysis, it was found that the suitability of land use was 95% classified suitable to spatial detail plan. To determine the suitability of the building in this study, it was seen from the activities of the building and the height of the building. Based on building activities, 9.30% of building activities that are not allowed and another 90.70% are classified as conditionally allowed buildings, allowed, limited alowed and limited and conditional. Meanwhile, based on the height of the building, there are 82.7% of buildings that comply with the spatial detail plan.
