Safety risk assessment using analytic hierarchy process (AHP) during planning and budgeting of construction projects Saman Aminbakhsh, Murat Gunduz ⁎, Rifat Sonmez Department of Civil Engineering, Middle East Technical University, 06800 Ankara, Turkey a r t i c l e i n f o a b s t r a c t Article history: Received 5 October 2012 Received in revised form 1 May 2013 Accepted 22 May 2013 Available online 6 June 2013 Keywords: Occupational health and safety Analytic hierarchy process Risk assessment Finance Prioritization Introduction: The inherent and unique risks on construction projects quite often present key challenges to contractors. Health and safety risks are among the most significant risks in construction projects since the construction industry is characterized by a relatively high injury and death rate compared to other industries. In construction project management, safety risk assessment is an important step toward identifying potential hazards and evaluating the risks associated with the hazards. Adequate prioritization of safety risks during risk assessment is crucial for planning, budgeting, and management of safety related risks. Method: In this paper, a safety risk assessment framework is presented based on the theory of cost of safety (COS) model and the analytic hierarchy process (AHP). The main contribution of the proposed framework is that it presents a robust method for prioritization of safety risks in construction projects to create a rational budget and to set realistic goals without compromising safety. The impact to the industry: The framework provides a decision tool for the decision makers to determine the adequate accident/injury prevention investments while considering the funding limits. The proposed safety risk framework is illustrated using a real-life construction project and the advantages and limitations of the framework are discussed. 1-s2.0-S0022437513000479-main.pdf

Risk assessment of safety and health (RASH) for building construction Saud Al-Anbaria, , , A. Khalinab, , Ali Alnuaimic, , , A. Normariahd, , A. Yahya Highlights • A general RASH has been developed with risks classified into Safety Risks and Health Risks. • 11 factors representing safety risks and 8 factors representing health risks were identified. • RASH method resulted in superior accuracy for assessment of risk zones than the existing RA method. • RASH method gave fewer errors than the existing RA method for four different scenarios. AbstractIn this research Risk Assessment of Safety and Health RASH method for building construction has been developed with risks classified into Safety Risks and Health Risks. 11 factors representing safety risks and 8 factors representing health risks were identified based on field survey in Oman. 40 Safety and Health specialists were involved in carrying out risk assessment using the existing method of risk analysis RA and the proposed RASH method. It was found that RASH method resulted in superior accuracy for assessment of risk zones than the existing RA method. The accuracy by RASH was almost twice the accuracy by RA. The overall percentages of the correct answers for the four scenarios using the RASH method and the RA method were 72.5 percent and 40 percent respectively. The proposed RASH method gave fewer errors than the existing RA method for all scenarios. Two scenarios were found to be the most problematic ones with largest overestimation of risks occur when using the existing RA method. Wilcoxon Ranked Test showed that the two methods are significantly different (z = −3.357, p > 0.01). The new method RASH is statistically acceptable and it resulted in better response in terms of estimating the risk than the RA method.

Activity based risk assessment and safety cost estimation for residential building construction projects G. Emre Gurcanli, Senem Bilir ⇑, Merve Sevim Technical University of Istanbul, Department of Civil Engineering, Division of Construction Management, Ayazaga Campus, Maslak, 34469 Istanbul, Turkey a r t i c l e i n f o Article history: Received 6 February 2015 Received in revised form 19 June 2015 Accepted 1 July 2015 Available online 16 July 2015 Keywords: Risk assessment Safety cost Scheduling Construction industry Logarithmic regression a b s t r a c t Fatal construction accidents are major problem in Turkish construction industry. Although new comprehensive legislation has been inured recently; level of consciousness in the industry is unsatisfactory and safety is perceived as an extra cost. Small or middle scaled residential projects have a big share in the industry and majority of the fatal accidents usually occur on such work sites. Focus of this study is small and middle-scaled residential construction sites. Drawings, technical specifications, bill of quantities of 25 concrete residential buildings with total areas that vary between 230 and 118,200 m2 in Istanbul were examined. Site visits and information gathering were performed from site engineers. This study aims to give an approach for safety cost estimation for the early stages of construction bidding phase using risk assessment activities and construction project scheduling by focusing on construction activities. Additionally, a cost analysis was performed and the results were compared and analyzed with a former project that focused on 30 concrete residential projects in Istanbul. Primavera P6 was utilized for scheduling, and risk assessment was conducted using the techniques applicable for construction projects (i.e., L matrix and Fine-Kinney). Finally, activity-based techniques were used for cost estimation. The results of this study reveal that the percentage of safety cost to the total construction cost is 1.92%. Also, to comply with the current legislation and minimize risks; 0.85 USD per man-hour should be spent according to 2013 rates and safety cost per unit area was found as approximately 5.68 USD. 1-s2.0-S0925753515001666-main.pdf

An occupational safety risk analysis method at construction sites using fuzzy sets G. Emre Gu¨ rcanli*, Ugur Mu¨ ngen Technical University of Istanbul, Civil Engineering Faculty, Construction Management Department, 34469 Maslak/Istanbul, Turkey a r t i c l e i n f o Article history: Received 18 February 2008 Received in revised form 26 September 2008 Accepted 15 October 2008 Available online 30 November 2008 Keywords: Construction safety Fuzzy sets Accident likelihood Accident severity Risk assessment a b s t r a c t The nature of construction work ensures that uncertainties are inherent in every condition; and on-site inspections generally use linguistic expressions rather than metrics to assess the risks of workers at a construction site. Additionally legal records, statistical data and documentation produced by companies are generally insufficient for determining risk. This fact increases the uncertainty of the job site atmosphere. This paper proposes a method for assessment of the risks that workers expose to at construction sites using a fuzzy rule-based safety analysis to deal with uncertain and insufficient data. Using this approach, historical accident data, subjective judgements of experts and the current safety level of a construction site can be combined. In the scope of this study, first 5239 occupational accidents in the construction industry are identified from 40,000 unclassified occupational accidents in all industries. Next, these 5239 construction accidents are investigated and classified in detail. Combining these data and the subjective judgement of safety experts, we derive three parameters namely the accident likelihood, current safety level and accident severity and they are utilized as input parameters for the fuzzy rule-based system. The method is then implemented on a tunnelling construction site and risk level for all type of accidents is derived. Relevance to the industry: The relevance of this study to industry is linked to the possibility of providing, through the use of proposed methodology, safety level scores for the construction sites that could result in work improvement and productivity. The application of the proposed method can reveal which safety items and factors are most important in improving workers safety, and therefore decide where to concentrate resources in order to improve the safety of the work environment. 1-s2.0-S0169814108001583-main.pdf
