Digitization and digital transformation in the construction industry becomes relevant due to the post-pandemic effect of SARS-CoV-2, in which it is necessary to be as productive as possible to mitigate infections. Digitizing the most important construction data allows project managers and decision makers, without the need to travel continuously to the construction site, to visualize in real time the main indicators of project performance. The Last Planner methodology is currently the most widely used for production planning and control in construction works; however, this methodology does not use indicators to know the performance of the work regarding time and cost, which is why it must be complemented with other traditional methods such as the Earned Value Technique, promoted and disseminated by the PMI. This study proposes an efficient integrated system that incorporates the main production planning and control methodologies, for which a mobile application was developed for data collection and digitalization, and a web services application that processes and displays real-time performance indicators, in order to find deviations from the plan in time and take appropriate corrective measures. For the validation, analysis and interpretation of the results obtained, the proposed system was implemented in a real sanitation worksite, where it was possible to demonstrate that the application presented is viable, since it allows the collection, processing and visualization in real time of the main field data in construction works. In addition, it is possible to know the performance of the projects in terms of cost and time, and to control the productivity of the main resources (labor, materials and equipment). Chapter I begins with the introduction of this work, briefly describing the impact of the pandemic on the construction sector and how it has managed to drive digitization and digital transformation in this sector, followed by the description of the research problem, where the obsolete form of data collection in the construction industry is described. It is also shown that this leads to not being able to know the performance of the project in real time, so that, many times, corrective actions cannot be taken to meet the project goals. The objectives of this study are also discussed, the main one being to propose an application for data digitalization and decision making with which it is intended to know the performance of the construction works in real time and thus take the necessary measures in an early manner. Finally, some background information on the research is discussed. Chapter II presents a wide theorical and conceptual framework, describing the Toyota production system, the lean production and lean construction theories, the most used methods for production planning and control, where the last planner system, the Earned Value Method and the classic productivity control methods of the different resources are integrated, as well as a brief description of certain concepts used in the thesis. Chapter III describes the methodology that proposes the digitization of the last planner system, the Earned Value Method and the classic methods of resource productivity control, which allows having the main field data digitized and thus knowing the project performance in real time. In Chapter V and VI, the aim is to simulate the data collection and implementation of the application in a real case, seeking to demonstrate its viability and the benefits achieved. Such application was executed in a sanitation project, where encouraging results were found to demonstrate the benefits of the proposed methodology of data digitalization, such as: knowing in real time the main indicators of the project, avoiding alterations of the project indicators, promoting the implementation of the last planner system, among others. Finally, Chapter VII discusses the analysis and interpretation of the results found and subsequently culminates with the conclusions and recommendations of this study.
