Abstract

enThe construction industry is a key industry in the Belgian economy. It brings thousands of employments all over the country and the net growth of 2016 gives us an insight of the good health of this sector. However, the latest good news on short term tend to overshadow a less pleasing observation that is valid for more than twenty years : «the construction sector su ers from a lack of productivity compare to the rest of the manufacturing industry». While other actors of the manufacturing industry (especially the automotive) succeeded in boosting their production in the past years in order to meet the still rising needs of the consumers, the construction industry seems to be stuck in a time warp. In the first place, this study aims to draw a report of the production in the construction sector to be able to give an explanation of this lag. This subject will lead us to the topic of Lean Construction. More a complete way of thinking and a philosophy then a toolbox to implement on projects, the Lean Construction will be the red lead of our thesis. In the second place, we will develop two submissions based on the optimisation of the storage areas on a construction site. Their common goal will be to increase the productivity on site. The first submission will focus on the feasibility of a system of vertical storage. It will bring to light the possible gains in time and space (of the storage area) that this solution could allow. The second submission consists in the study of the placing of the storage areas with the help of an algorithm that tried to make it as realistic and unbiased as possible. The analysis of a case study will also point the potential gain in time that we could expect if the algorithm was used. Finally, our results from the first and second submission will give us a total gain in time and space. From the one hand, the vertical storage would allow to spare in the best case up to 14% on the steel reinforcement activities and gain 30% on the storage space needed for the steel. On the other hand, the optimisation of a logic placing of the storage areas, helped by our algorithm, would result in a time gain on the implementation of the materials on site. The potential gain would be up to 14% for some materials. The solutions, developed in this thesis, aim to participate to the optimisation of the productivity that we try to improve every single day in Belgium.
