# BIM-GIS-Based Approach for Quality Management Aligned with ISO 9001
## 1 Introduction
However, none of these studies address vertical building construction projects, where quality management involves different spatial challenges and coordination requirements. In addition, existing studies [29] do not specifically align their approaches with ISO 9001:2015. Therefore, this research aims to develop and validate a method that integrates BIM and GIS to support ISO 9001:2015-based quality management workflows in building construction projects. Furthermore, the proposed approach can be framed within Cyber-Physical Systems (CPS), where integrating digital technologies and physical construction processes facilitates automated data collection, real-time monitoring, and structured decision support [30]. These capabilities align with the current trends in the smart industry, which emphasize the use of interoperable digital tools to enhance efficiency, traceability, and responsiveness in construction quality management. This research aims to develop and validate a method that integrates BIM and GIS to support ISO 9001:2015-based quality management workflows in building construction projects. This integration is intended to enhance traceability, georeferenced inspection control, and digital transformation in quality processes throughout the construction phase. This research is guided by the following question: _To what extent can the integration of BIM and GIS, aligned with ISO 9001:2015, improve the traceability and effectiveness of quality management processes in building construction projects?_  
In line with this objective, this study contributes a novel digital workflow that integrates BIM and GIS technologies explicitly aligned with ISO 9001:2015 requirements for construction quality management. This integration enables georeferenced, process-based inspection records within the BIM environment, enhancing traceability, documentation, and compliance with international quality standards. In addition to the theoretical framework, this study responds to practical challenges commonly faced in construction quality management environments, including fragmented information across stakeholders, paper-based documentation processes, and difficulties in accessing or updating inspection data in real time on-site. These challenges hinder traceability, slow down decision-making, and increase the risk of errors during construction. The proposed tool, named QualiSite, was explicitly designed to address these challenges by enabling centralized, georeferenced, and digitally accessible quality records within the BIM environment. To demonstrate its applicability, a case study was conducted focusing on the construction of reinforced concrete walls. This implementation allowed linking the status and progress of quality controls with a parametric BIM model, facilitating visualization and management of inspection documentation during construction. QualiSite improved the traceability of quality data and supported informed decision-making, helping to prevent errors during the construction phase [31]. The article is organized as follows: Section 2 presents the stages of the research methodology. Section 3 presents the state of the art of quality management, BIM, and GIS. Section 4 presents the workflow followed for the development of the tool. Section 5 presents the details of the case study and the results obtained. Section 6 presents the discussion.
