Life cycle cost modelling using 6D BIM in construction: A comparative study

Abstract

Life Cycle Costing (LCC) and Building Information Modelling (BIM) are among the important current trends in the construction industry. LCC contributes to the objective management and measurement of costs during the entire lifetime of a building and BIM represents one of the digitalization efforts related to the Construction 4.0 initiative. Because life cycle cost modelling using 6D BIM has the potential to bring significant positive effects such as cost savings and reduced environmental burden, this paper aims to study the development of this concept in the Czech Republic and Austria. The legislative environment, the actual usage of LCC and BIM in practice, as well as problems faced by the Czech and Austrian construction industries, are discussed in this comparative study. The results show that the practical level of use is still relatively low in both countries, yet specific differences were identified, for example those related to the definition of legislative requirements and the availability of standards and specifications.
