Abstract
Abstract. Sustainability is one of the main scientific and public topics of today. This includes the sustainable transport and infrastructure. One of the ways how to achieve higher level of sustainability is through the implementation of BIM (Building Information Modelling) into the road design process. However, to create a safe road network, which is also necessary for achievable sustainability, it is essential to consider the Road Safety Audit (RSA) principles throughout the BIM applications. The paper discusses the possibilities of involving the RSA in the process road design in I-BIM (Infrastructures Building Information Modelling). Within the individual phases of the preparation of a transport project and the application of the safety audit tools in BIM applications, it is possible to achieve a significant increase in the level of safety. This approach is shown within the paper on the implementation and use of supplementary road safety devices, specifically the road restraint systems. Currently, the individual components are defined by their main parameters in specific libraries. However, their definition is only as a general object where many of the supplementary parameters or fundamental design characteristics, such as working width or minimal length, are not included. This may lead to potential design flaws or safety hazards which have to be subsequently corrected in further phases. The objective of the paper is to identify the current deficiencies, primarily the missing road safety perspective within the BIM process. The aim is to enable appropriate selection of safety equipment during the design or to provide sufficient information for the mandatory RSA.
Highlights
BIM or Building Information Model is a modern methodological approach to manage, effectively interpret and archive information about a building project in all phases of its development, including the subsequent management of the final building until the end of its functional cycle
Eastman of the Institute of Physical Planning, CarnegieMellon Univ., Pittsburgh, United States, who defined the principles of the building information model (Eastman et al, 1974)
The most significant development of BIM has been reached during the last decade, when BIM was implemented in the current European legislation (Official Journal of the EU,2014)
Summary
BIM or Building Information Model is a modern methodological approach to manage, effectively interpret and archive information about a building project in all phases of its development, including the subsequent management of the final building until the end of its functional cycle. A key aspect is the interactive cooperation between the different experts involved in all phases of the project life cycle in order to input, retrieve or update information in the model In this iterative process, it is possible to recreate a single virtual model of the design work that is not a mere three-dimensional geometric representation but a "dynamic" model, i.e. it contains a range of additional or complementary information relating to materials, dimensional elements, thermal and energy performance, cost, safety, maintenance, demolition and decommissioning (Biancardo, et al, 2020). The paper shows the current shortcomings of the BIM process in the area of the inspection or assessment of socially significant structures (such as linear ground structures) by professional supervisors, i.e. road safety auditors It concerns the process of evaluation of specific construction elements within the individual cycles of its implementation. It is these assessments that should be considered as part of the BIM processes and the conclusions resulting from them should be incorporated into the BIM information database of the specific construction
