Abstract.A construction project failure primarily defined as disappointment in either one or the combination of cost, time, quality, and management. This study is an effort to identify the Critical Success Factors (CSFs) and the relationship between various attributes of a project success. A preliminary comprehensive literature study of previous research works served as the basis of the CSFs, which will be the guide factors to predict the probability of a project success. At the end of the study, the contribution of each critical success factor to the project success will be established.

Abstract. Construction Workers (CWs) are the main source of manpower that is necessary to every construction project. Non conducive and hazardous working environment at construction site will affect the physiological health of the construction labour. This study is conducted to explore the impact of job stress and emotional stress to the CWs that potentially lead to injuries incident in Penang. Twelve stressors were identified through factor analysis. Then, the stressors are classified into five main categories. Questionnaires were developed according to the stressstressor relationship. The correlation between factors of injury incident (stressor) and stress shows that lack of autonomy and inappropriate safety equipment lead to the emotional stress among the CWs with 0.287 and 0.204 respectively. In addition, poor physical environment causes the job stress among CWs with the correlation of 0.270.

Construction industry plays an important role in the Malaysia economy. One of the factors that contribute to this industry is infrastructure projects. Rework in infrastructure projects can cause the collapse of the Malaysian economy since it is detrimental to project outcomes. However, less attention was given regarding rework within the Malaysian construction industry especially in infrastructure projects. The purpose of this paper is to investigate the rework causes in the infrastructure project at Pulau Pinang. To acquire opinion of professionals from the construction industry about rework causes in infrastructure projects, questionnaires were distributed via Google form and received 52 responses. Data was analysed through SPSS 25.0 and ranked according to the level of importance. From this research, the results revealed that subcontractor factors and design related factors are the major categories that contribute to rework causes. In addition, the study showed that communication effectiveness within owners and changes made at request of the client are the main rework causes which considerably influenced infrastructure projects performance.
