It is important to provide efficient, clear and unambiguous methods to form 3D property units, as well as register 3D property RRRs (rights, restrictions and responsibilities). The 3D property formation process should facilitate solutions to complicated problems within building projects (for example space above and below the ground) and provide secure and lasting rights in complex situations. Therefore, 3D property formation could use the same processes as for the formation of other property units, but adding specific rules and standards concerning the use of 3D models. Building Information Modelling (BIM) contains rich details of building characteristics such as structures, elements, spaces, schedules, etc. that can form the physical models of the 3D cadastre. The 3D property formation process requires that BIM data are exchanged between actors. To model this exchange, we utilize an open BIM process standard Information Delivery Manual (IDM). IDM helps to clarify the detailed property formation process, facilitates actors’ communication, harmonizes different product data models delivered and stored, identifies the results of that activity, as well as improves the management more efficiently and collaboratively. Level of Information Need (LOIN) is a framework that defines the extent and granularity of information, in order to prevent delivery of too much information. The LOIN specifies the granularity of information exchanged in terms of geometrical information, alphanumerical information and documentation, which should be used to specify the information delivery between actors. In this paper, we use LOIN as a basis to specify information requirements according to the 3D property formation purposes, and design a developed process of the Swedish 3D property formation in IDM. In the study, LOIN fulfills the requirements of forming 3D cadastral property in BIM models and harmonizes all involved actors in the whole process in IDM with a more common and standardized approach. The proposed methodology aims to facilitate a standardized and unambiguous digital 3D property formation process on a national level in order to improve and enhance the digital Swedish Cadastral and Land Administration Systems

Property-oriented systems are a new kind of information systems that are based on concepts of properties instead of concepts of things or classes of things. By focusing on properties, the property-oriented systems become more flexible and more suited to the dynamic early stages of design than the traditional class-oriented systems can be. The theoretical framework for property-oriented systems developed within the BAS•CAAD project and presented in this thesis has previously been presented in several papers, a selection of which are included here. Some of the basic considerations from the papers are further developed in a separate chapter. Additionally, the thesis covers several questions regarding prerequisites for and implications of property-oriented systems. These questions

Construction industry suffers from low efficiency in design, and the information flow creating bottlenecks for the production process. Tracing and managing information through design process needs standards both for requirements and Building Information Models in a life cycle perspective. Structuring functional requirements is of great interest for the construction industry and especially for companies developing industrialised housing system that often have control over the whole manufacturing process. The delivery of a new low-carbon economy in Europe puts pressure on the construction industry to reduce the energy consumption for buildings. Therefore is one national standard for energy requirements tested on a building system and evaluated in an Information and Communication Technology-environment (ICT) that supports the design process for industrialised construction. The result of the research shows that the transformation of requirements to technical solutions needs functionality that supports the design process by using standards for requirements. A rigid building system based on well defined design tasks together with a technical platform, both for spaces and physical elements, work as a backbone for development of ICT support systems. Product Life Cycle Support (PLCS), as a standard that enables flexibility in categorisation of information through the construction design.

Customers, clients, suppliers and society have needs and requirements that have to be captured and formalized to govern the goals of design and production and finally operation and maintenance. This requires continuous information about the real estate and city properties, all in open and transparent standards. The information needs to be collected, stored, processed, integrated, extracted, visualized and interpreted, something that requires advanced information systems and deep domain knowledge. BIM repositories will become a necessity for the ability to manage changes and consolidations/synchronizations of heterogeneous applications. Integrated planning, integrated design with multiple alternatives and functional, spatial interfaces, and integrated supply chains with system performance requirements and specifications, the important functionalities of IDDS, Integrated Design and Delivery Solutions, are examples on possible usages of a BIM repository. This paper presents the planned and also performed studies of a BIM collaboration Lab, which are based on the experience and results from the BIM Collaboration Hub and the research in the EU project InPro. It also demonstrates how the experiments in the lab are supported by through life support standards.

Facility managers are responsible to fulfil this need during the whole life cycle of the construction works in a manner that maximises the economical profit, minimises the environmental impact and keeps the risk of failure at a low level. A prerequisite for efficient facility management (FM) is long-term planning of MR&R actions. This requires management of a large amount of information, a process that includes gathering, storing, processing and presentation of data. With the development of open Building Information Models (open BIM) and standardisation of Industry Foundation Classes (IFC) new possibilities of efficient management of FM information have emerged. Due to its parametric and object-oriented approach, the open BIM-concept rationalises the information management and makes it more cost effective. This paper discusses how open BIM, with the aid of IFC, and...
