Abstract. The study intend to investigate sustainability knowledge using "AKASA" model. This model comprises all the literacy level which is the awareness, knowledge, attitude, skills and action. 234 students from 5 selected private universities were surveyed using questionnaires. Students were specifically selected from year 2 and year 3 from private universities in Klang valley, Malaysia. The study intends to investigate the environmental literacy level specifically the knowledge variable. The parametric study was conducted with descriptive analysis and the results shows that the environmental knowledge is at high level compared to other environmental literacy variables among year 2, year 3 and combine year 2 and year 3.

The growing demand of housing has prompted the Malaysian construction practitioners to realize the benefits of Industrialised Building System (IBS). Despite its advantages, IBS in Malaysia is plagued partly due to inefficient adoption strategy and lack of awareness among the practitioners. Hence Building Information Modelling (BIM) is introduced to facilitate the life-cycle of the project by eliminating construction inefficiencies. The aim of the study is to evaluate the BIM functions in relation to Malaysian IBS work process. In order to achieve the aim, the effectiveness of IBS and BIM implementation in Malaysia were identified. The data is collected through interview sessions with seven (7) IBS-BIM practitioners. Data from the interview were analysed using Content Analysis, summative approach. From the analysis, it was found that there were 4 BIM functions (clash detection, visualization, shop drawing, coordination) are able to integrate in 3 IBS wrork process (initial work, component production and installation). The causal relationship of IBS-BIM was formulated through linear equation method tabulated from content analysis results. The causal relationship of IBS-BIM explained BIM integrated functions in relation to IBS work flow. This study is essential to assist IBS practitioners to strategies their strategies in enhancing its productivity through the BIM implementation.
