Dynamic Planning of Construction Site

Abstract

Dynamic planning of a construction site is an unexplored part of a project execution process, according to its absence in literature. The aims of this study are first to highlight this issue basically in linear construction projects and secondly to explore its value through practical applications. For this purpose, factors that influence the selection of the construction site location and then the costs resulting from this selection are examined. The location which maximizes the production rate is investigated. The location must simultaneously minimize the non-productive time/cost and adhere to project’s technical specifications. According to the project’s time schedule, the “ideal” site location is explored at time intervals taking into account the work progress. The optimization method that is presented aims to minimize the cost that arises from the site non-productive time/cost and site relocation cost as part of the total construction cost. The validity of the model is tested in two real case studies. The first study investigates a vertical axe to Egnatia Odos Motorway (5.5km) and the second regards a section of Egnatia Odos Motorway in North Greece (15km). The results show that for the second project the relocation is required, with a profit of 100.000 €, whereas for the first one, relocation has no profit for the contractor. The concluding remark is that during the planning phase of linear projects, a study of dynamic site location should be performed in order to investigate whether there is a profit for the constructor from the relocation of site or not. This profit could cover expenses of financing according to the project cash flows. © 2019 The Authors. Published by Budapest University of Technology and Economics & Diamond Congress Ltd.
