4D and 5D BIM: A System for Automation of Planning and Integrated Cost Management

The construction sector has difficulty in catching the rapidly developing technology era. While the sectors are rapidly adapting themselves to the new era, firms that do not invest in innovation lose their value at a fast pace. When we look at the Fortune 500 list, it is seen that the biggest leap is made by companies in the IT sector. However, the situation is observed to be the opposite for construction companies. Despite the enormous investment costs and the huge risks involved, construction companies are unable to compete with the leaders of the digital world and falling down in the list. The losses of time and cost are increasing in the construction sector which lags behind in the digitizing world. The systematic analysis of these losses with analytical methods remains limited and there are problems in project management approaches. The industry today invests into digital transformation with Building Information Modeling (BIM) to deal with these problems in the construction sector and to produce a solution according to their dynamics in the digital world. BIM is the digital twin model of actual construction consisting of data-rich 3D objects. Accurate management of a data-rich model is possible with data management techniques. In order to fully benefit from this digital reflection of construction projects, the sector needs to establish processes based on basic theories of digital data management. This study is designed to provide a methodology in which the BIM 4D and 5D processes are handled as integrated and business intelligence approaches. While approaching Information Modeling from Building perspective, some basic approaches to data science have been integrated with 4D and 5D processes. The main objective of the study is to contribute to the digitalization process and to present a proposal for the application of the business intelligence in BIM processes.
