The implementation of Agile Management in the construction industry is still incipient. Literature in the subject is scarce and further, is yet not conclusive about the performance of these methodologies for managing construction projects. This thesis aims at developing a framework to implement agile methods for managing the front-end phase of infrastructure projects, with the purpose of enhancing their performance. This framework will be the outcome of solving the main research question: How can Agile project management improve the performance of infrastructure projects in early phases?
