Currently, 2D-based analogue building subdivision plans are used to represent the spatial extent of private, public and communal property ownership rights. These plans are recognized as posing a range of challenges in terms of communicating the spatial complexity of ownership spaces within multi-storey buildings. In response to these challenges, three-dimensional (3D) digital data environments are being investigated as a potential approach for managing complex, vertically stratified ownership arrangements. The argument presented in this article is that Building Information Modelling (BIM) can be adopted for 3D digital management of data related to complex ownership spaces. BIM provides a common and 3D digital data sharing space, underpinning a reliable basis for facilitating collaboration and decision-making over the lifecycle of buildings. However, ownership attributes and the spatial structure of ownership arrangements inside buildings are yet to be accommodated within the BIM data environment. In this article, we present a range of required data elements for managing complex ownership spaces, which have been elicited by investigating current practices pertaining to subdivision of ownership spaces within multi-storey buildings in Melbourne, Australia. An open data model in the BIM domain is extended with these data elements and a prototype model for a real multi-storey building is implemented to demonstrate the viability of the extended data model for 3D digital management and visualization of data related to complex ownership arrangements. 相似文献

As we realize that we spend most of our time in increasingly complex indoor environments, applications to assist indoor activities (e.g. guidance) have gained a lot of attention in the recent years. The advances in ubiquitous computing made possible the development of several spatial models intending to support context-aware and fine-grained indoor navigation systems. However, the available models often rely on simplified representations (e.g. 2D plans) and ignore the indoor features (e.g. furniture), thereby missing to reflect the complexity of the indoor environment. In this paper, we introduce the Flexible Space Subdivision framework (FSS) that allows to automatically identify the spaces that can be used for indoor navigation purpose. We propose a classification of indoor objects based on their ability to autonomously change location and we define a spatial subdivision of the indoor environment based on the classified objects and their functions. The framework can consider any 3D indoor configuration, the static and dynamic activities it hosts and it enables the possibility to consider all types of locomotion (e.g. walking, flying, etc.). It relies on input 3D models with geometric, semantic and topological information and identifies a set of subspaces with dedicated properties. We assess the framework against criteria defined in previous researches and we provide an example. 相似文献

针对现代城市建设审批工作中,建筑报建材料与原有设计规划信息不一致、建筑设计与规划管理脱节的问题,该文基于建筑信息模型技术设计实现了三维建筑报建核查系统。该系统通过建筑信息模型数据与三维GIS数据的无缝融合,建立了建筑信息模型语义特征与报建要素之间的映射关系,构建了面向不同需求层次的建筑报建审批模式与作业流程,较好地实现了基于三维GIS平台的三维建筑报建信息自动核查。实验结果表明,该系统支持下的报批审批流程能够充分利用实际业务的建筑信息模型设计数据,支撑建筑设计报建的相关业务工作,提升业务管理水平。 相似文献

房地不动产具备天然的立体特性,在三维空间中对其进行准确刻画是当前城市地上地下综合开发的关键问题,国内外学者已经提出了各类房地不动产数据模型,旨在解决房地不动产的管理与权利空间的三维表达问题。分析国内外学者的研究成果发现,国外学者提出的房地不动产数据模型多以地籍为核心展开,不能完全适用于我国的房地不动产管理;而国内学者虽兼顾了地籍和房产,但忽略了建筑实体、建筑空间与产权空间的关系,无法将房地不动产信息与建筑物信息模型（Building Information Modeling,BIM）整合,不利于房地不动产的精细化管理。针对以上问题,本文提出了基于IFC（Industry Foundation Classes）标准扩展的房地一体化三维不动产数据模型,并通过实例验证了该模型在我国房地不动产管理上是可行的。研究结果表明,本文提出的模型正确表达了各类建筑对象和产权对象,既可以支持业务相关的关联关系的查询,也支持GIS常见拓扑关系的查询和表达,该模型除了能表达符合我国体制的房地不动产对象外,还关联了BIM模型中的建筑构件、建筑空间, 为城市建设与运维管理提供技术模型支持。 相似文献
