Effective Risk Assessment Models for Construction Industry

The construction industry is known to have overwhelming numbers of occupational accidents worldwide, which attribute to continuous demand for care and improvement. Due to this enormous risk, identifying the contributing factors should be prioritized for accident prevention and hazard control. However, it is evident that the lack of enforcement and preventive inspection in Turkish Republic of North Cyprus causes the necessity of new approaches for improvement. To begin with, we collected data from the Ministry of Labor to gather information on accident modes, work trades, and loss of working days due to occupational accidents. Subsequently, checklists were prepared based on the rules and regulations in North Cyprus construction industry. There is no risk assessment model study in the literature related to North Cyprus construction industry. The main aim of the thesis is to develop an effective risk assessment models for North Cyprus construction industry to create a better working environment for employees by minimizing the risk at the site and taking the precautions. Various risk assessment models were identified to be modified, developed then applied in the North Cyprus construction industry: traditional, preliminary, fuzzy, and modified fuzzy risk assessment models. These models implemented in the North Cyprus construction industry to determine the most suitable and effective one. Apart from the insufficiency in general site safety, this study shows that the safety barriers are not adequate, accident frequency and severity of accidents are high; especially for falling from a height. Generally, worker characteristics were composed of disproportionally low experienced workers, and the training given was found to be inadequate. In addition, the risk level for each accident mode and the hazard index for different construction sites are calculated. All of these helped us develop a special Risk Assessment Model unique to North Cyprus circumstances
