The Fifth Dimension of BIM – Implementation Survey

In today's digital age, the rate of process automation is increasing. Building Information Modelling (BIM) is being used for this purpose. BIM is a smart, model-based process that provides construction professionals with an overview and tools for more efficient planning, designing of building solutions, facility management of buildings and infrastructure. Cost management represents a very important part of BIM technology. 5D-cost model in Building Information Modelling is used for budget monitoring and cost analysis. 5D-cost model allows to directly extract individual quantities and then assign unit costs to them. 5D-cost model increases level of safety and reduces or makes use of cost at all stages of the construction project more efficient. The paper discusses the issue of the fifth dimension of BIM. The main objective of survey was to create overview of 5D (BIM) implementation in selected countries and to bring comparison within this topic. Based on a thorough analysis of the sources, the overview and comparison was carried out. The main conclusion of the research suggested that the selected countries have a different degree of 5D BIM implementation.
