A Study on the Assessment of Risk Management in High-Rise Buildings

Abstract

AbstractConstruction activities in general, high-rise building construction in particular, come with a variety of risks. The reason for the enhanced risk factors could be attributed to the complexity and dynamic nature of the construction work involving high-rise buildings. Construction activities in high-rise buildings accounts for the majority of the accidents every year. In this work, an effort is taken to accurately assess and analyze different risk management factors like Physical Factors (PF), Organizational Factor (OF), Work Environment (WE), Safety Environment (SE), Design Factors (DF), Safety Protection (SP), Safety Behavior (SB), and Quality Factor (QF) in the construction of high-rise buildings in Chennai, Tamil Nadu. The study used quantitative survey method to collect the data from the key stakeholders. To study the influence of different risk management factors, 250 responses from construction personnel, clients, contractors and consultants were collected and analyzed using statistical tools. The reliability analysis show that all the risk management factors have Cronbach’s Value above 0.7, indicating that the factors are reliably measuring the underlying constructs. The results of the empirical analysis show that work environment is the most dominant factor affecting the risk management in construction projects based on the mean value. Based on the CFA-SEM analysis, it is inferred that all the factors like Work Environment (WE), Physical Factors (PF), Organizational Factor (OF), Safety Environment (SE), Design Factors (DF), Safety Behavior (SB), Quality Factor (QF), and Safety Protection (SP) contributes significantly to the Risk Management Factors at 0.01 level. CFA Analysis shows that Design Factors (B = 0.880), Physical Factors (B = 0.866) and Safety Environment (B = 0.847) have significant contribution toward Risk Management Factors at 0.01 level. The findings of the study have several implications for managing risk factors in the high-rise building construction projects. The findings enrich the existing body of literature on risk management factors in the construction of high-rise buildings.KeywordsConstruction safetyHigh-rise building projectsRisk management factors
