Impact evaluation of the Construya Columbia (Promotion of Sustainable Construction Practices in Colombia’s Vulnerable Urban Sectors) programme.

The report focuses on construction interventions by trained workers from 2015 to 2018. It assesses the condition of dwellings post-intervention, comparing the performance of trained and untrained workers. The study shows improved practices in most trained workers, indicating a positive impact on housing conditions.

The report's findings validate the project's approach, demonstrating that training enhances construction quality, thereby improving living conditions in vulnerable urban sectors.
