Construction projects always deal with high-risk business activities, facing constant errors, and producing unwanted waste, leading to low productivity and sustainability. Lean Construction (LC) and Building Information Modelling (BIM) approaches have been recognized to resolve those issues. The implementation of both technologies is becoming popular amongst industry practitioners across the globe, claiming that they could also address the sustainability concerns in the construction industry. However, the usage of both innovations is fragmented, mainly, with their tools and processes being manipulated separately. Therefore, this paper aims to explore Lean-BIM collaborative approach towards establishing more sustainable construction projects, focusing on the Malaysian construction industry. The objectives of this paper are to identify the impacts of Lean-BIM collaborative approach on sustainability and to determine its capabilities in impacting the sustainability requirements for construction projects. This study conducted a survey by questionnaire in which 100 responses were successfully gathered from various stakeholders. Using Relative Importance Index (RII) of Statistical Product and Service Solutions (SPSS) software, the surveyed results were ranked concerning Lean-BIM impacts and capabilities. The findings acknowledged that the most-ranked Lean-BIM impacts towards sustainability in construction projects are in terms of productivity, quality, and safety and risks management. Whereas the highest-ranked Lean-BIM capabilities highlighted are Lean pull planning approaches, and BIM coordination and virtual mock-up. This paper could assist the construction practitioners’ decision-making in managing sustainability for construction projects to venture competently into Lean-BIM innovation.

In the modern construction business, Green Building (GB) has become the flagship of sustainable development. Previous studies reveal it can essentially deal with a wide range of challenges for project development, from minor concerns to devastating disasters. These days, there are a lot of disastrous abrupt tragedies happening all around us, such as floods, which may harm both people and animals. The current developments have been cited as one of the contributing elements to the tragedy. Mostly due to unanticipated actions to guarantee that development is proceeding as planned, integration across process, people, and environment. Thus, GB has been seen as an approach that is able to resolve issue related to a disaster. It can lessen the likelihood that one will occur. Delivering successful green building projects is still a challenging task due to its complexity in design and construction regardless the fact that the number of green building projects around the world is increasing. Thus, the objective of this study is to identify the barriers in managing construction sites for green building projects. This study used quantitative methods with a close-ended questionnaire as the research instrument. By using stratified sampling, 36 respondents were responded to this study. The data collected were summarized using critical analysis and descriptive analysis. The data were analyzed using SPSS software. The findings show that the major barriers encountered while managing construction sites for green building projects are cost concerns; collaboration issues; and financial struggle.

Since construction 4.0 was introduced in our construction industry, there has been a trend increase in awareness of adopting technology such as Building Information Modelling (BIM) in improving green building performance. Therefore, numerous researchers studied the possibility of Building Information Modelling (BIM) that the practitioner can imply in achieving sustainable and green results in Green Assessment Tools. Therefore, this paper aims to highlight the challenges of implementing Building Information Modelling (BIM) in green assessment tools. The objectives of this paper are to identify the awareness of BIM as a Green Assessment tool among the stakeholders and investigate the challenges in implementing Building Information Modelling (BIM) in Green Assessment Tools The research method for this paper is quantitative method research where the data obtained from questionnaires which have been distributed to consultant firms, contractor, client, and accessors that involve in green assessment. The data had been analyzed by using SPSS software which produces the frequency and descriptive statics in terms of percentage. The result showed that the financial constraint is ranked first which shows that, the high initial investment could be the crucial challenge in implementing BIM in Green Assessment Tools.

The COVID-19 pandemic emerged as the most talked-about topic of the year, damaging the economy, and upsetting the lives of many people and businesses across industries. Its effect, which varies by industry, was enormous in the construction industry, causing Malaysian construction projects to suffer the consequences of escalating material costs during the pandemic and post-pandemic period. This study aims to improve the effects of the escalating construction material costs by identifying the factors influencing the escalating construction material costs in construction projects from the contractor's perspective. This research was conducted using questionnaire surveys and distributed to Selangor Contractors Grade G6 and G7 registered with the Construction Industry Development Board (CIDB). Descriptive statistics and ranking analysis were used in data analysis. The finding showed nine (9) factors influencing the escalating construction material costs, transportation costs & fuel price increases, supply chain disruptions & material shortages, labour shortages, higher labour costs, demand increases, economic factors, tariff increases & trade policy changes, health & safety costs increase and Government policies & regulations. Thus, this study must be put into consideration, as it ultimately helps to enhance the construction industry's performance. Finally, construction professionals, industry, and the government will benefit.
