Building Information Modeling (BIM) is a systematic process used to model information involving the use of computer-generated (n-dimensional) software to simulate the planning, design, construction, and operation of a building. Currently, BIM technology is an important approach used by most project clients (public and private) to boost project effectiveness in terms of time, cost and quality of construction projects to meet client demand. However, previous studies showed that BIM-based project implementation in Malaysia faces greater challenges due to project attributes that causes low demand of project clients to adopt BIM. Hence, the purpose of the paper is to investigate the impact of project attributes towards client demand by adopting BIM across project life cycle. A crosssectional survey was conducted in Malaysia among the three project stakeholders: the public sector, private sector, and contractors using BIM for their projects. Seven (7) significant project attributes (i.e., feasibility, definition, duration, project location, objectives, size and type) and three (3) triangle of client demand (i.e., time; cost; quality) were subjected to Parametric Pearson Correlation. The results showed that there exist a significant relationship between the project attributes and client demand. The results suggest that project clients (public and private) should take a consideration of project attributes in fulfilling the client demand at the early stage of project commencement to maximize the BIM benefits to other stages of construction.

Solar energy is the most common supply of energy for all kinds of life on Earth. It is also the fundamental source of all energy sources except nuclear energy. However, solar technology has not progressed to the same level as traditional energy sources. It has several obstacles, including high costs, irregular and unexpected weather, the necessity for storage, and low efficiency. Thus, this paper explores and discusses the components and materials of solar panels, the assembling and assembling, and the market potential for solar panel mechanical cleaning systems in commercial buildings. A simulation method through the application of Google SketchUp Pro 2021, Keyframe Animation, and Windows Movie Maker for the demonstration enhanced the visual of the potential innovation product of solar panel mechanical cleaning system. It offers to create a Solar Panel Mechanical Cleaning System that regularly clears the collected dust on its surface while maintaining the performance of the solar power plant. The structure is a mechanical system that can move autonomously on the surface of solar panels using dry cleaning techniques such as a rotating cylindrical cloth and a squeegee while keeping in mind the limited availability of water in areas where such plants are mostly found. This initiative also intends to eliminate human interference in the solar panel cleaning operation, as it is a dangerous environment for workers under the blazing heat.

The Fourth Industrial Revolution (IR 4.0) has recently compelled the construction sector to employ Building Information Modelling (BIM) as a central repository for digital project information. BIM has thus become a major influence in the Architecture, Engineering, and Construction industries (AEC). Although BIM improves design quality by minimising disputes and decreasing rework, there is limited study on applying it throughout a project for quality control and effective information use. Thus, this paper explores and discusses the quality efficiency of BIM-based construction projects. There were 206 questionnaires distributed to government agencies/clients, consultants, and contractors. Quantitative data analysis was conducted using Statistical Package for Social Science (SPSS). Consequently, twenty-seven ( 27) attributes of quality efficiency of BIM-based construction projects were deemed the determining factor by the three research groups (Government, consultant, and contractor). The research result was to help BIM-based construction project players, especially government agencies/clients, contractors, and consultants, by giving a roadmap to be BIM-compliant and seeing the adoption process to attain BIM level 3 (full integration) for the Malaysian construction sector.

Rapid development of the construction industry and decrease in land space have resulted in the development of high-rise buildings. This makes the usage of cranes inevitable. However, usage of cranes has often caused accidents which result in deaths and also varies injuries. This paper aims to increase the level of safety for high-rise building construction when using crane. Literature and empirical data were obtained in this study. Review of related literature was conducted to identify problems associated with the use of cranes in high-rise building constructions. Questionnaire survey was carried out on industry players to recognize the current practice in the industry. Document analysis was then implemented to highlight the existing flaws of the current crane design. An innovation was then proposed to try counteract the problems highlighted earlier. It is expected that the innovation proposed will have a huge impact to the level of safety in crane usage for high-rise building construction. Being simple and economical, it is targeted that the innovation is easily adopted by construction players.
