Integrating BIM for health and safety in industrial heritage restoration: a case study on gasometer refurbishment

The restoration of industrial heritage buildings presents unique challenges, particularly in ensuring structural integrity, safety, and sustainability throughout the process. It is evident that activities such as structural modifications, demolition and retention carry significant risks. The field of building engineering plays a pivotal role in the transformation of aged industrial edifices into functional and sustainable spaces, while simultaneously preserving their historical significance. Nevertheless, the design for safety and health approach has yet to be implemented with regard to the protection of workers and the general public, as part of the broader concept of sustainability. This study explores the integration of Building Information Modelling (BIM) in the refurbishment of the Phoenix-West Gasometer, emphasizing risk mitigation and project efficiency. By utilizing a multi-phase approach, the research incorporates 3D modelling, hazard identification, and 4D project scheduling to enhance decision-making. The study leverages Autodesk Revit, Navisworks, and Tekla Structures to develop a comprehensive model that integrates safety attributes, material assessments, and environmental risk management. The project timeline was structured into distinct phases, including structural reinforcement, soil remediation, prefabrication, and final safety checks. Through case study comparisons with the Oberhausen and Augsburg Gasometers, the research highlights best practices in heritage restoration, such as soil contamination management, prefabrication strategies, and climate control solutions. The findings demonstrate that BIM-driven restoration can enhance safety compliance, reduce construction risks, and improve project efficiency. This study contributes to the growing body of knowledge on heritage conservation and digital construction methodologies, offering a structured framework for future industrial restoration projects.
