# Infrastructure BIM Platform for Lifecycle Management
## 1 Introduction  
The safety and stability of infrastructure is an important factor in the economic and social development of a country. Over the last few decades, the demand for improved technologies for the efficient and cost-effective management of aging infrastructure has increased due to the inefficiency and resource waste of traditional infrastructure management systems [1]. Building Information Modeling (BIM) technology has been accepted as one of the best tools for the enhancement of management systems in Architecture, Engineering, Construction, Owner, and Operator (AECOO) industries [2]. Recently, research for introducing BIM into the infrastructure industry, such as for roads, bridges, tunnels, etc., as well as the building industry, has been carried out [1, 2, 3]. BIM has the advantage of the lifecycle management of infrastructure, from planning and design to construction and maintenance [4, 5]. The introduction of BIM at the planning stage will systematically enhance project management and collaboration between stakeholders [6]. BIM also helps, not only collaboration in the design stage, but also design quality enhancing and error reduction, etc. [7]. In the construction stage, BIM can increase productivity and workflow by reducing the wastage of time and resources [8]. Moreover, stored BIM data on infrastructure during the planning and design stage can be used afterwards for maintenance. Effective maintenance of infrastructure is possible through the integration of BIM with state-of-the-art technologies, such as unmanned robots and Unmanned AerialVehicle (UAV) systems with digital cameras or 3D Laser Scanning and Light Detection and Ranging (LiDAR), 3D model construction algorithms, and artificial intelligence algorithms, etc. [9; 10; 11]. Globally, the BIM market will expand to USD 15.06 billion by 2027. Many countries, such as the USA, Canada, Germany, the UK, China, Japan, India, South Korea, and Singapore, have adopted and developed BIM [12]. In South Korea, the Ministry of Land, Infrastructure, and Transport (MOLIT) announced in December 2020, the \"introduction of full-scale BIM in the construction industry\" for the full-scale introduction of BIM into infrastructure projects [13]. The \"Basic Guidelines for Construction Industry BIM\" and \"BIM activation roadmap for 2030\" were then prepared for the lifecycle management of infrastructure by sharing information from the planning, design, construction, and maintenance stages of the construction industry with every stakeholder to maximize productivity [14]. In addition, in the \"Basic Guidelines for Construction Industry BIM\" (published in 2020), the procedures for applying BIM to construction, major standards defined by BIM, and a Common Data Environment (CDE) were established. Therefore, international standard formats, such as Industry Foundation Classes (IFC) and Extensible Markup Language (XML) are recommended to manage infrastructure in the CDE, because infrastructure management projects involving various stakeholders using different software programs such as Autodesk BIM 360, Trimble Connect, Bentley, etc. are usually difficult to consolidate [15; 16; 17]. Therefore, in this article, a systematic analysis of the current state of BIM and state-of-the-art techniques for infrastructure management is performed. A BIM platform-based lifecycle management method is then proposed. The objectives and novelties of this study are as follows: (1) A literature review of BIM and state-of-the-art techniques for the lifecycle management of infrastructure is performed, (2) a lifecycle management method combining state-of-the-art techniques is proposed, and (3) the proposed infrastructure BIM platform is validated using a simple scenario. It is confirmed that collaboration with stakeholders in the CDE in construction management is possible using an infrastructure BIM platform.
