In recent years, industrial and research communities have devoted considerable effort

to the digitalisation of AECOO processes with the main objective of achieving a new paradigm for any Design and Construction project which should allow the highly desired improvement of the productivity in the sector.

The basic axis of this revolution has been the subsequent levels of BIM methodology implementation across the world, which has recently reached an important milestone with the creation of the ISO-19650 international standard and includes the data migration from the previous design and construction phases into the Facilities Management (FM) systems and for on-going operations. Besides this trend, another paradigm change is currently boosting across manufacturing sectors which are moving to the Industry 4.0 concept, by the improvement Product Lifecycle Management (PLM) methodology based on Smart, Connected Product Systems (SCPS) or Digital Twins. Following this, the document presents the analysis of the current State of the Art to develop

a generic definition for Building Digital Twins as well as their adaptation as

an extension of current SoA AECOO procedures, based on this ISO-19650 to hence allow an easier uptake of this PLM in the AECOO sector and beyond, by considering the most significant real estate stakeholders also during Operation and Maintenance.

随着时代发展，三维地理信息系统(3DGIS)的重点正由室外转向室内，但是室内模型获取较困难，现有方法存在效率过低、成本偏高，模型数据质量不佳等问题。建筑信息模型(BIM)是建筑行业信息化的产物，其数据完整、全面，可以作为潜在3DGIS建筑模型数据的一个重要来源。本文基于GIS的建模标准CityGML与BIM的IFC标准，研究了两种标准的异同点，建立两种标准的对应关系并进行了模型间的转换，将基于IFC的BIM建筑模型转换成了满足CityGML标准的3DGIS模型数据。

With the development of the times, the focus of 3D Geographic Information System (3DGIS) is moving from outdoor to indoor. However, the indoor model is difficult to obtain. The existing methods have the problems of low efficiency, high cost and poor quality of model data. Building information model (BIM) is the product of the information of construction industry. The data of BIM is complete and comprehensive, and can be used as a source of potential 3DGIS indoor data. Based on the standards of CityGML and BIM, this paper studies the similarities and differences of the two standards. Furthermore, we establish the corresponding relationship between the two standards and conduct the transformation between the two models, transforming the BIM into the model that meets the CityGML standard.
