As Building Information Modeling (BIM) becomes the predominant technology in the construction industry, contractors, amongst other activities, need to conduct Site Logistics Planning (SLP) in the BIM environment during different project phases. 4D BIM modelling is an important step towards developing BIM models ready for the construction execution phase. However, in developing such models, currently no standard exist which would guide contractors towards a thorough analyses of site logistics. Moreover, there is a scarcity of studies and research on level of detail of construction schedules, which makes SLP hard to implement in a BIM environment. We addressed this problem by employing a case-study method for understanding how 4D BIM models should be designed to enable effective SLP and dynamic site layout creation. The results show that the following input data for SLP in the BIM environment is needed: hierarchically structured 3D BIM model, Work Breakdown Structure (WBS), detail schedule, resources constraints, and defined onsite temporary facilities. Additionally, we have found that the activities should be further divided into work operations to enable SLP. Our results enable contractors to create a dynamic site layout according to the BIM principles. Moreover, the findings are an initial step for the further standardization of the BIM model for the SLP in the BIM environment.

Building Information Modeling (BIM) is an intelligent 3D model-based process that enhances productivity and management performance of construction projects. Recognizing many benefits of BIM, governments of the most developed members of the European Union encourage BIM usage which results in a higher BIM awareness and BIM adoption. These facts suggest that BIM is becoming the norm within construction industry. On the contrary, Croatia and Slovakia have been very low in BIM application and have done little to support BIM initiatives. Previous studies suggested several strategies to increase the BIM application, where providing BIM education at university level is one of them, so universities need to update their curricula accordingly. In this study we compared implemented Construction Management (CM) BIM education on master’s study at the Faculty of Civil Engineering Košice and Zagreb. The results show that BIM education at the both faculties should be connected with other departments on the same faculty, other disciplines but also with real companies and projects. Such extension will provide civil engineers with wider BIM knowledge related to interoperability, integration, communication, collaboration, standardization and clash detection. Thus, BIM education improvement will have good impact on rising BIM awareness and will be good incentive for further BIM implementation in Croatia and Slovakia. This study is an extension of paper presented on Creative Construction Conference 2018 in Ljubljana. In this paper we showed deeper statistical analysis of CM educational programs in Croatia and Slovakia as well as relationship between BIM awareness and BIM education in both countries.
