Abstract

The mitigation of construction site accidents is fundamentally contingent upon the supervisory competence of site managers, whose oversight practices exert substantial influence on worker safety behaviors. Human errors emanating from managerial personnel can catalyze unsafe practices among construction workers, thereby emphasizing the critical importance of reducing such managerial errors. Given that fatigue and job stress constitute primary determinants of performance, this investigation examines the effect of these variables on the human errors among building construction site managers. The empirical findings demonstrated that site managers exhibited significant levels of fatigue, while their aggregate job stress levels were characterized as moderately elevated. A statistically significant correlation was established between site managers' human error frequency and specific job stressors, particularly job demands and perceived organizational injustices. Additionally, the study determined that when managers' fatigue levels exceeded a predetermined critical threshold, there was an increase in both time and sequence error occurrences. This research provides substantial empirical evidence indicating that interventions targeting the reduction of specific job stressors and fatigue management strategies designed to maintain job stress levels below critical thresholds are essential for minimizing human error incidence among site managers. These findings are instrumental in developing targeted interventions to enhance safety performance and operational efficiency within construction environments.

건설 현장의 사고 감소는 근본적으로 현장관리자의 관리 역량에 달려 있으며, 현장관리자의 관리 관행은 건설근로자의 안전 행동에 상당한 영향을 미칩니다. 현장관리자의 휴먼에러는 건설근로자의 안전하지 않은 관행을 촉진할 수 있으므로, 이러한 관리적 오류를 줄이는 것이 매우 중요합니다. 피로와 직무스트레스가 업무성과의 주요 결정 요인이라는 점을 고려하여, 본 연구는 이러한 변수들이 현장관리자의 휴먼에러에 미치는 영향을 분석합니다. 실증 분석 결과, 현장관리자들은 상당한 수준의 피로를 보였으며, 전체적인 직무스트레스 수준은 중간 정도로 높은 것으로 나타났습니다. 현장관리자의 휴먼에러와 특정 직무스트레스 요인, 특히 직무요구 및 불합리한 조직체계 사이에는 통계적으로 유의미한 상관관계가 있는 것으로 확인되었습니다. 또한, 관리자의 피로 수준이 미리 정해진 임계치를 초과할 때 시간에러 및 순서에러 발생률이 증가한다는 사실을 확인했습니다. 본 연구는 특정 직무스트레스 요인 감소를 목표로 하는 개입과 직무스트레스 수준을 임계치 이하로 유지하기 위한 피로 관리 전략이 현장관리자의 휴먼에러 발생을 최소화하는 데 필수적임을 시사하는 상당한 실증적 증거를 제공합니다. 이러한 연구 결과는 건설 환경에서 안전 성과와 운영 효율성 향상을 위한 맞춤형 개입을 개발하는 데 중요한 역할을 합니다.
