Development of BIM-Based Risk Rating Estimation Automation and a Design-for-Safety Review System

Abstract

Various laws and guidelines on designing for safety have been developed world-wide, and these were used to identify risks at construction sites in advance through qualitative and quantitative safe management. In other words, attention is being paid to safe management based on design drawings and models rather than field visits. It was predicted that the introduction of the concept of design-for-safety would minimize risk at construction sites through safe management in the design phase. This is because the efficiency and reliability of such a strategy has been demonstrated in various cases abroad. However, domestic design-for-safety suggests a very limited range of evaluation items, so there is a limit to using such strategies in construction sites. Building information modeling (BIM) technology is attracting attention in situations when safe management must also be based on design proposals. Although previous studies on the identification of falling disasters and automatic identification of hazards have been conducted, these studies only deal with a limited range of items for identifying risk items. For example, BIM-based risk extraction, which is limited to falling disasters, is only at the level of risk recognition that can be derived based on the process table, and evaluation is not made accordingly. It is difficult to assess the overall disaster risk in many of the items required for risk rating estimation. In this paper, we solve the above problems by deriving a BIM-based risk rating estimation scenario based on the disaster scenario for automating BIM-based risk rating estimation, and we developed an evaluation system using this method. The BIM-based risk rating estimation methodology was presented through BIM-based hazard extraction, evaluation of requirement information, evaluation item selection, and using the evaluation system in a design-for-safety review.

Analysis of the Current State of Automation of Hazard Detection Processes in BIM in Slovakia

“…An electronic questionnaire was prepared from acquired theoretical knowledge of hazard detection in BIM [15,17,[20][21][22][23][24][42][43][44][45][46]51,52], and practical knowledge with BIM management based on experience in the construction industry in Slovakia. It was composed of 33 questions connected by logical links, so that it was possible to exclude inappropriate respondents (e.g., if they did not perform preparation and control of HS on their projects or did not use BIM on any project).…”

Improvements of Design for Safety in Construction through Multi-Participants Perception Analysis

“…For example, in South Korea DfS is applied only to certain public construction projects, and it is supposed to be implemented upon 80% completion of the construction document preparation phase. Therefore, DfS in South Korea has many limitations owing to the fact that the applicable range of construction projects is relatively narrow compared to those in other countries [18][19][20][21][22][23].…”

“…The DfS process is implemented in the design phase and is carried out in collaboration with multiple participants during its application to the construction phase. During this process, however, participants have different perceptions of DfS problems and the corresponding improvements that are necessary [6,10,16,[21][22][23][24][25][26][27][28]. Therefore, to enhance the effects of DfS, each participant must increase his awareness of DfS and provide suggestions for improvement priorities [28].…”
