Abstract

The construction industry faced significant challenges due to the COVID-19 pandemic. This study examines the lessons learned from construction projects in Chile after the pandemic, through semi-structured interviews with project management professionals. The method used is a qualitative analysis of interview transcripts to identify both positive and negative impacts, as well as lessons learned. The results show that the adoption of technologies and digitalization had positive effects on projects. However, negative effects were identified, such as increased execution times, concerns about workers' mental health, and issues in the supply chain. Regarding lessons learned, the need to maintain improvements achieved during the pandemic is emphasized, with digitalization and new technologies being key elements. This study helps understand how the pandemic changed construction projects in Chile, providing a comprehensive view of the effects of COVID-19 on the sector and offering valuable information to companies and organizations to adapt to future post-pandemic contexts. © 2025 Pontificia Universidad Catolica de Chile.
