The present project demonstrates a way to improve construction processes, with improvement understood in terms of increased productivity. To achieve this objective, the research presented here relies on discrete event simulation models to analyze transportation logistics, as well as distribution and storage of structure- and foundation-related materials for two reinforced-concrete buildings in Bogota, Colombia. Analysis of the case study can be divided into three phases. In the first, construction processes were characterized, and a field study was conducted via data collection and video/photo recordings. In the second, simulation models were created for the real scenario, with deficiencies and opportunities for model improvement diagnosed and different theoretical scenarios proposed. In the third and final phase, these theoretical scenarios were compared using models to determine their strengths or weaknesses versus the real construction scenario. Based on the comparative study carried out, discrete event simulation allowed for the integration and behavioral observation of all variables affecting the construction process. As a result, deficiencies became conspicuous; in turn, improvements were readily identified in order to establish the best scenario from a cost-benefit perspective
