CASE STUDY ON SAFETY MANAGEMENT IN CONSTRUCTION PROJECT

There have been significant reductions in the number and the rate of injury over the last 20 years or more. Nevertheless, construction remains as the one of the high risk industry. The purpose of this study is to examine safety management in the Malaysian construction industry, as well as to highlight the importance of construction safety management. The industry has contributed significantly to the economic growth of the country. However, when construction safety management is not implemented systematically, accidents will happen and this can affect the economic growth of the country. This study will try to put the safety management in construction project as one of the important elements to project performance and success. The study will focus on construction project in Malaysia and a case study will be done at “Kuala Lumpur International Airport 2 – New Low Cost Terminal Project”. The study will also emphasize on awareness and the importance of safety management in construction project. The data will be collected by doing the questionnaire and a case study. The analysis of the survey will be done by using the Relative Importance Index (RII) and Cronbach's alpha using SPSS software. The scores were then transformed to importance indices based on the formula

The Use of Marine Sand in Bituminous Mix•

Over the past decade, dramatic increasing in truck traffic, heavier axle loads, various environmental impacts and higher tire pressure had contributed to severe pavement distortions. In Malaysia, permanent deformation (creep deformation) is a continuously pavement distortion problems which caused by effect of temperature, successive stresses, excessive high bitumen content from improper mix design and insufficient compaction during roadway construction. In bituminous mix, fine aggregate's recent trend is using mining sand. Comparison in term of performance towards creep deformation between marine sand and mining sand as fine aggregate are key purpose for the study. For experiments, aggregate gradation are done for coarse aggregate; granite, fine aggregate; marine sand and mining sand as "well as filler; ordinary Portland cement. It is to determine the percentages of material used for making Marshall Mix sample. After conducting Marshall Mix design, stability tests is conducted upon each of sample to determine the optimum bitumen content by plotting graph of stability, density and void in mineral aggregate versus binder content. Dynamic creep test is performed to compare the performance of both samples. The result revealed that marine sand reaching stages of failures is twice as much compared with mining sand. It proves that usage of marine sand in bituminous mix increased its resistance towards permanent deformation (creep deformation)
