Evaluation in construction projects can be seen as a judgment of the project, and it is a way to find out what could improve in the project. The project evaluation could be discussed with the project participants and other people in the company, bringing feedback through communication. This feedback could generate lessons learned, finding what could improve, but also how to do it. Lessons learned can be documented, and they can later be used to solve a problem in different projects. This study focuses on those three steps, (i) evaluation, (ii) feedback, and (iii) lessons learned. A case study was performed in order to understand what exists in different departments of transportation across the United States of America regarding those three steps. This case study involved a survey design along with a descriptive analysis, and content analysis. Based on the results of this case study, an evaluation process involving those steps was developed. The process suggests the use of scorecards to help with evaluation, along with a lessons learned form that guides lessons learned documentation and communication. A maturity model was also developed to help departments of transportation employees understand what currently exists in their companies and where to start with the process in order to improve evaluation, feedback, and lessons learned along with the company. Based on this process, a training was developed to help people in different departments of transportation to implement the process, showing examples of how and when to use the process. The training was delivered asynchronously so that it would be self-directed, and it was given the opportunity to take the training as a group to increase interaction. The training was tested with a small group in order to get feedback on the training content, delivery, and use. Based on the feedback, the process developed could be applicable to help agencies perform evaluations and document lessons learned, improving overall project results for the company.
