Constructivist multi-criteria model to support the management of occupational accident risks in civil construction industry

Abstract

Civil construction is one of the industrial sectors with continuous growth globally, particularly in Brazil in the last 50 years. Unfortunately, it is also one of the productive segments with the highest incidence of accidents, which overshadows its merits as a driver of economic growth and job creation. The damage to workers’ health caused by accidents at work results from the presence of work environment risk factors. Therefore, this study aims to manage these risk factors for the civil construction industry. The work is original with respect to building a model to support risk management in civil construction for a specific and relevant context. It is ensured by presenting an unprecedented approach to the sector that incorporates information not considered by classic generic approaches. This research, thereby, seeks to build a model to support the risk management of accidents in the workplace in the prefabricated concrete construction industry. It is a case study with a constructivist approach and an exploratory and descriptive character, incorporating the Multicriteria Methodology for Decision Aiding-Constructivist (MCDA-C). The main findings include (i) identifying the strategic objectives: occupational safety policy, work environment, machines and equipment, condition of materials, procedures and methods, and skills, which were operationalized via 58 criteria; (ii) examining the scales of the criteria such as the performance profile of the current situation and the goal, highlighting the vulnerabilities and potentials; (iii) proposing improvement actions for the vulnerabilities, thus supporting risk management in the organization. Among the contributions, managers and professionals in the field contribute to the possibility of using an instrument customized to the context and legitimate to their concerns and values stands out. Furthermore, the contributions of researchers include the challenge of improving their generic models with the knowledge of personalized models.

A Review of Data Mining Strategies by Data Type, with a Focus on Construction Processes and Health and Safety Management

“…In risk management field 25 out of 61 papers dealt with data on the "risk management process". Into this class the 54 observations out of 202 concerned the following topics: awkward working postures [7,19]; compliance with Health and Safety standards [2,4,47]; risk assessment [21,51,53,63,66,77,79]; safe climate [44]; slope instability [10,17]; teaching-training tasks [5,6,78]; unsafe behaviours [25,72]; worker fatigue-heat stress [38,69,73]; site image [1,46]. Antwi-Afari et al [7] used deep learning networks to automatically extract relevant features with spatial-temporal dependence acquired by a wearable insole pressure system.…”

“…In the next stage, the Construction of the Family of Points of View, there is a more effective participation of the decision maker, which allows to build the criteria that best align with its values (Bortoluzzi et al, 2010). Semi-structured interviews are conducted, with the elaboration of open questions adapted to the context, seeking that the decision maker identify the concerns that directly or indirectly influence the research focus problem (Ensslin et al, 2022). Through these interviews, it is possible to identify the Primary Evaluation Elements (EPAS), being characteristics or properties of the context of what the decision maker thinks impact their values (Bortoluzzi et al, 2010).…”

Benefits of Implementing Occupational Health and Safety Management Systems for the Sustainable Construction Industry: A Systematic Literature Review

“…A constructivist multi-criteria model analysis was utilised to create a model to support the management of the risk of accidents on construction sites by Ensslin et al [114]. The study identified strategic objectives and examined the criteria scales, including performance profiles, and proposed vulnerability improvement activities.…”
