Statistical Analysis of Jobsite Safety Assessment in Construction

Abstract

Construction industry is one of the most hazardous industries. Accidents may occur during construction which results in serious injuries and death to employees and also may cause severe damage to equipment. Hence it is important to prevent or minimize accidents in the construction site. Safety during construction is very important for each employee. This project deals with job site safety analysis in construction site by identifying the causes for accidents and implementing solutions for preventing the accident in the construction industry. From the literatures it was studied that statistical analysis is better way to analyse the construction jobsite safety and important factors that are affecting the safety in construction is identified from the literatures. Questionnaire regarding the factors affecting safety in construction site is also prepared. Then primary data should be collected from the various construction companies and secondary data should be collected from their clients. Then the data’s are ranked by two different techniques, primary data was ranked by using Relative important index method and secondary data was ranked by the Garrett’s ranking technique. Then the companies which are following safe safety procedures should be found out using Statistical analysis. This data is analysed in Statistical Package for Social Science (SPSS) software and the major factors which affect safety in construction should found out through comparison of primary and secondary data by paired sample t-test. With this approach, it is possible to evaluate the uncertainty regarding safety in construction.
