Accelerated urbanization, a lack of urban planning, and a significant housing deficit are increasingly driving low-income families in major Latin American cities—such as Lima, Bogotá, and Cali—to resort to progressive housing as an alternative. In Lima alone, more than 700,000 people live in high-risk conditions prone to earthquakes and tsunamis, making Peru one of the most seismically vulnerable countries in the world. Most homes in these areas fail to meet even the most basic construction standards. In response to this challenge, the Construya projects in Colombia and Peru were launched to improve the quality of life in vulnerable urban communities by promoting safe, healthy, and sustainable construction practices. The projects focused on raising awareness among families and institutionalizing affordable training for construction workers. Applying a systemic approach, Construya collaborates with a broad range of ecosystem actors—including construction material distributors and manufacturers, training institutions, business associations, municipalities, universities, and innovation centers—to drive sustainable impact and long-term change.
In 2024 an ex-post impact assessment in Colombia revealed a strong appreciation for the Construya methodologies and a broad expansion of the training model. However, the ecosystem analysis showed that not all changes introduced by the project had been sustainably anchored. Despite this, there is a favourable environment for implementing systemic adaptations, and the positive impact on housing has remained stable over time.
The main challenges to systemic anchoring in both countries relate to the limited capacity of training providers to respond effectively to the needs of private companies. While Construya courses and resources continue to be used and valued, training institutions often lack the capabilities to engage with businesses, even though companies are willing to invest in training for master builders. Cost efficiency and scalability remain crucial factors in determining how widely such training can be offered.
The initiative aims to consolidate systemic changes by
Key performance indicators—such as the number of trained construction workers and the sustained quality of training—will be used to measure progress during the anchoring phase.
