Advanced risk management strategies for safety enhancement in temporary building construction works

Abstract

Introduction: In the construction industry, a primary focus is often placed on the main structural components of buildings. Concurrently, temporary works such as scaffolding, formwork support, and tower cranes are frequently overlooked during planning and design. However, these temporary works are crucial in influencing decisions related to risk assessment, cost management, project scheduling, and construction methods. There is a pressing need for more comprehensive written regulations and statutory guidelines to effectively manage temporary engineering works.

Method: This research draws on international standards, including the Code of Practice for Temporary Works Procedures and the UK's Construction Design and Management Regulations, as well as resources from the Temporary Works Forum of the International Temporary Works Association. By systematically analyzing key policies and reviewing the practices of international construction companies, the study seeks to identify the most critical risk factors using a robust risk analysis framework. The research focuses on temporary works during the planning, construction, and dismantling phases, addressing twenty-three major risk factors. To achieve this, the study employs a Risk Breakdown Structure (RBS), utilizes Analytic Hierarchy Process (AHP) questionnaires, and conducts a Risk Impact and Frequency Analysis (RIFA) based on Importance-Performance Analysis (IPA). Collaborating with technical departments from international engineering firms, the research evaluates the effectiveness of risk management in Taiwan's construction sector. Field surveys were conducted across 25 construction projects, involving 152 experienced on-site project managers who provided valuable insights.

Results: The findings help pinpoint and prioritize key risk factors within the temporary works cycle. In-depth interviews with senior executives provide a detailed analysis of the current allocation of risk management resources and propose effective risk mitigation strategies.

Practical applications: This research establishes management standards for temporary works, recommending enhanced safety practices, continuous workforce training, and improved risk communication to deliver substantial benefits across the construction industry.
