Building Information Model (BIM) is a powerful tool for managing and utilizing data throughout the lifecycle of buildings and infrastructure. This paper explores the options, and considerations, of using BIM data for the Land Administration (LA) domain. The ISO19152 Land Administration Domain Model (LADM), as a widely recognized international standard for Land Administration domain, is currently undergoing revision. The new Edition will be multipart, with 6 Parts, including Part 4 (ISO19152-4) about Valuation Information, specifying the characteristics and semantics of valuation registries maintained by public authorities. This valuation part may include incorporating advancements in the representation and management of property-related information, as well as aligning with the architecture, engineering, and construction (AEC) industry. BIM has a significant impact on the AEC industry, since its adoption transforms traditional processes, enhancing among others, visualization, lifecycle management and facility operation. By integrating information from BIM models into the LADM Part 4, several benefits can be achieved, such as: more accurate 3D property representation, dynamic and realistic assessment of property value, automation of valuation processes and compliance with industry regulations. Therefore, this paper investigates how to integrate BIM data with the LADM, particularly in the context of Cyprus. The mapping between the existing Valuation Model of Cyprus and the basic concepts of LADM Part 4 takes place and a proposed valuation information model for Cyprus based on LADM Part 4 is designed. This model is further enriched by the integration of data derived from a real-world mixed-use buildings. Additionally, we presented the primary objective of this paper along with its significance within the context of the Cyprus Land Registry system, with particular focus on its relevance to the Valuation Department.
