The construction industry is a crucial indicator of economic development and a significant contributor to a country's GDP(Furkan et al., 2023). However, it is recognized for its potential adverse environmental impacts. The effects include environmental degradation, resource depletion, and social disruption, underscore the need for enhanced construction practices (Marrero et al., 2024). In modern construction-management, technology plays an indispensable role in overcoming challenges and achieving project goals (Elkhayat et al., 2024). Additionally, integrating sustainability into construction practices is increasingly important for environmental and social responsibility (Maqbool et al., 2023) . This case study examines the pivotal role of technology in managing a residential construction project in Lisbon, which faced numerous challenges. These challenges emerge from variables such as Location, Field related and the unique characteristics of the site(Jacques de Sousa et al., 2023). The project is to build a four-story residential building and aimed to retain the historic facade of the original structure while integrating modern residential design. Despite significant encountered delays, the project achieved the desired outcome. Key challenges included multiple failed attempts to retain the facade, significant vegetation growth after the rainy seasons, unforeseen water springs during excavation, and disruptions from road closures and airplane traffic. Technological interventions involved advanced structural analysis software, drone technology, ground-penetrating radar (GPR), GPS and logistics-management software, and AI-generated imagery(Gao et al., 2024) (Brusselaers et al., 2024) (Moshood et al., 2024) . These solutions were crucial in addressing the challenges and ensuring effective construction-management . Data for this study were collected through direct observation. Future research can explore the long-term impacts of these technological solutions on construction efficiency and sustainability.
