Implementation of an environmental management system (ISO 14001) on an underground gallery construction site in Casablanca Morocco

The integration of an Environmental Management System (EMS) in the construction sector, often characterized by the lack of a standardized production chain, represents a major challenge for sustainability. This study, conducted on a construction site in Morocco, a country still underrepresented in sustainable development initiatives, examines the implementation of an EMS compliant with ISO 14001:2015. The underground gallery construction site, located in the Sidi Bernoussi area of Casablanca, aims to collect rainwater. It is managed by CAPEP, a Moroccan company specializing in public works and construction. This research stands out for its contextual approach, filling a significant gap regarding the practical application of international environmental management standards on a Moroccan construction site. The study is based on comprehensive data collection to identify and assess the main environmental aspects and impacts of the project, using a methodology based on severity, probability, and control criteria. Based on the results, an environmental action plan was implemented to optimize the management of solid and liquid waste. This plan has improved waste separation at the source, increased solid waste recovery by 30 %, and reduced disposal costs. Awareness and training programs were established to encourage more efficient practices in resource and waste management. The practical impact of this research lies in the clear demonstration of the benefits of an EMS in improving the environmental performance of construction projects in Morocco. Furthermore, this study offers specific recommendations, such as improving manager training, to encourage other companies in the sector to adopt similar practices, thus strengthening the environmental governance of the construction industry. • Implementation of an EMS based on the ISO 14001:2015 standard on an underground gallery construction site. • Measurable reduction in the environmental impact of the construction site. • Improving waste management practices. • Strengthening environmental management skills within site teams.
