    Description: The limited visibility experienced by crane operators in construction sites poses significant challenges, leading to reduced performance and safety concerns. Obstructive elements, such as existing buildings, construction elements, or vehicles, can block the crane operator's field of view, hindering their ability to execute lifting operations with precision and confidence. To address this issue, this study presents a novel approach using Building Information Modelling (BIM)-based diminished reality (DR) to enhance visibility by dynamically removing obstructive objects from the crane operator's perspective in real-time. The research employs a marker-based registration system that effectively aligns BIM data with the physical environment, ensuring realistic and precise DR visualization. Additionally, a semi-automatic selection method that involves minimal intervention from the user is employed to select desired objects. To generate the background, the system utilizes real-time observation data from occluded areas. A validation through a case study demonstrates the practical applicability of the developed system in real-life construction scenarios

    Description: Enterprise resource planning (ERP) is an integrated business management system aimed at monitoring and maximizing resources and efficiency; on the other hand, Building Information Modelling (BIM) represents a broad series of approaches to design, based on the development of virtual models that cover the building’s whole lifecycle. The integration of ERP systems within the Architecture, Engineering and Construction industry, while promising, has yet to reach the same results that its use has achieved in other fields. Although BIM and ERP are traditionally systems employed in different disciplines, they both deal with data integration and customization, and are designed to reconcile varied and scattered information. A mutual incorporation could allow for a more comprehensive understanding of the project starting from the initial phases, while also granting a more streamlined construction process and a reduction in errors and complications later on. The aim of this paper is to identify the possible connections between the two systems examining a case study, starting from an analysis of the current state of the art regarding this implementation, and by evaluating both the existing limits and the future possibilities of this implementation, for both small and medium enterprises (SMEs) and the industry at large
