Abstract

In most of the developed countries, the construction industry as one of the significant industries in terms of contribution to Gross Domestic Product (GDP). Investments in infrastructure projects are playing a vital role in contributing to the economic growth of a country. While the development of infrastructure projects continues to boost up the business of construction industry, it has become more complex and larger in scale. Consequently, there are certain hazards and risks in the construction sector, being a potentially-hazardous manoeuvres, which has considerable hazard risk to the workers connected with it. Some cause factors of hazards have been identified in previous studies by other researchers. However, there are only few researches on the hazards that arising in infrastructure construction projects. As such, this research study is aiming to identify the cause factors of hazards in infrastructure construction. In continuing such efforts, numerous safety and health programme is critical to be utilised to manage the undesirable events leading to the occurring of hazard activities. Quantitative approach was adopted in this research. Therefore, SPSS software was used to integrate the data collected from the distribution of questionnaire. Total 372 sets of questionnaires had been distributed and 97 responses were collected. Frequency statistics and descriptive statistics were generated from SPSS software and tabulated in tables for the purpose of analysis. Discussion and summaries were made accordingly based on the results. Reliability test based on Cronbach’s Alpha coefficients was conducted to determine whether the data collected and the scores for each variable are reliable and acceptable. With all being said, the cause factors of hazards and the strategies to overcome the risks arising due to such hazards was studied in this research. Some of the cause factors being identified are poor management team, workers’ failure, failure of equipment and machinery as well as external issues. Several strategies also being clarified such as HIRA process, prevention and control, communication and coordination as well as HAZOP analysis. It is generally acknowledged inside industry when all is said and done that the different methods of hazard appraisal contribute enormously towards the improvements in the safety of complex operations and equipment.
