Abstract The effectiveness of security and accessibility to all facilities supplied in the neighborhood area was evaluated using the Pedestrian Infrastructure Quality of Service methodology. The method is known as a "mix of land uses to test pedestrian connectivity," and it encompasses land use and connectivity within a 400-meter walking radius, as indicated on the map. According to the findings, 28% of pedestrians in the age range of 25–34 years old were eager to walk in a neighborhood with good pedestrian infrastructure and a safe environment for walking. The elderly were less willing to walk because of the lack of pedestrian infrastructure, which prevented people from using walking as a mode of transportation. Professionals, who accounted for 45.6 % of all responses, favored increased provision for pedestrians in the neighborhood area to encourage more people to walk instead of driving private vehicles.[...] Read more.

Abstract Constant need-for-change in the construction market and social trends has resulted in the demand for more adaptable building systems. The ability to practise and accommodate change has consequently become a new necessity for buildings. Adaptability, therefore, is to be considered in both the pre-construction stage and the entire life cycle of the construction. The further civilization develops, the more we need to take advantage of the Open Building Systems (OBS) concept, introduced to the construction industry almost 70 years ago. However, conventional methods are still common due to the lack of knowledge in OBS, resistance to change, monopoly of conventional building materials manufacturing, insufficient legislation, and lack of end-user’s awareness. The ability to practise and accommodate changes has consequently become a new necessity for building construction. This research aims to address the interactions among the influential factors of OBS. The initial move was to identify and verify the significant open building influential factors in a conceptual model based on previous relevant literature. Then the second step was to find the interactions between the variables through the Decision-Making Trial and Evaluation Laboratory (DEMATEL) technique. The results indicate that one of the most significant and main factors is the "Level of Independence", and the main cause factor identified was "Standardization (St)", which had a major role in the success of construction OBS performance.[...] Read more.

Abstract Building Information Modelling (BIM) Construction Lifecycle Process offers digital construction solutions throughout the whole project lifecycle by providing sustainable productivity and quality and increasing the work collaboration and efficiency of the design teams. BIM represents the development and application of computer-generated n-dimensional (n-D) models to simulate building construction planning, design, construction, and operation. In Sarawak, the BIM technology does not meet the construction stakeholder's expectations during the project lifecycles in different stages, which resulted in low BIM implementation. Therefore, this research study aims to identify the salient barrier factors to the implementation of BIM in the Sarawak construction industry, specifically in the design stage. To achieve the research study, the methodology is applied through literature review, followed by an online interview with BIM experts in Sarawak Construction Industry. Lastly, the findings of this study indicate the most salient factors faced by the Sarawak construction industry until the present, in terms of Technology, Cost, Management, Personal and Policy, such as (1) Lack of active participation from consultants in the project team, (2) Low enforcement from client, (3) Lack of senior management support, (4) Lack of desire to change of the older generation to implement BIM and (5) Lack of the knowledge regarding the cost benefits for implementing BIM.[...] Read more.

Abstract Building Information Modelling (BIM) is one of the most advanced developments in the architecture, engineering, and construction (AEC) industry that can generate a 3D virtual information model which can be used for planning, design, construction, and operations. As Building Information Modelling (BIM) approaches the construction industry as a new technology and process, changes in the industry have created some barriers to BIM adoption in Malaysia. This research aims to enhance the implementation of BIM in the construction stage of Sarawak's construction industry by identifying and classifying the critical barriers. This study fills this current knowledge gap and enhances the understanding of BIM in the construction stage and the factors that hinder implementation in Sarawak. To develop the challenges being faced in this industry, a set of barrier clusters based on people, process, policy, technology, and cost were pre-identified through a literature review, and a structured interview involving three BIM experts was conducted on WebEx to refine these barriers with the current industry situation. As an outcome, this study identified 49 of the barriers from the literature and refined them into 26 of the barriers under their main clusters. Interestingly, they all validated the fact that lack of government involvement in BIM implementation is an undeniable barrier factor to growing BIM utilization and reaching its full potential. This study will form the basis of further research, and additional studies focusing on prioritizing these identified barriers for strategic planning would help the construction players in their swift transformation to BIM. [...] Read more.

Abstract Petrochemical is a vital pillar industry for the national economic growth wherein the past few years, it has produced a huge amount of petroleum sludge. Petroleum sludge (PS) contains toxic and carcinogenic-mutagenic compounds and heavy metals, which are a major source of pollution in the environment. Thus, it needs to be properly treated and disposed of. Correspondingly, this paper presents a review of the techniques to treat petroleum waste to effectively immobilize the heavy metals and highlights their possible application as construction materials. This review concludes that each treatment method (i.e., solidification, stabilization, incineration, bioremediation, centrifugation, etc.) has its own merits and demerits and may be more suitable for certain applications than others. The use of pyrolysis, solidification, and stabilization techniques has been demonstrated to be potentially beneficial in protecting the environment from contaminants in PS and further recycling PS as cementitious materials. However, the selection of suitable treatment methods has to be made based on the chemical composition of the waste, method capacity, costs, and disposal standards. Therefore, an overall evaluation is required prior to treatment method selection to ensure the safe disposal or recycling of petroleum waste. This review could improve basic knowledge of PS treatment and disposal techniques and serve as a future guide for recycling PS as a building material.[...] Read more. Full text
