The building sector is still criticized for its excessive energy use and negative environmental effects, even with significant improvements in recent years. It makes a major contribution to the world's energy, waste, and water use. This study investigates the possible benefits of using Building Information Modeling (BIM) technology in environmentally friendly building methods. It also seeks to identify and rank the major obstacles to the industry's integration of sustainability and BIM. The study aims to accomplish its research objectives by means of a questionnaire survey approach. The three primary categories of the possible benefits associated with BIM are social, economic, and environmental, which correspond to the generally acknowledged elements of sustainable development. The provision of a centralized database that facilitates the administration of the full building lifetime, less material waste, and increased design efficiency have all been noted as key benefits. In the building industry, BIM approaches have shown to be quite successful in improving sustainable practices. The study does, however, point out a few difficulties. The number of people with a BIM degree has increased significantly, but there are still not enough qualified professionals with the necessary knowledge and experience. Project managers with the necessary skills are needed to oversee BIM deployment successfully. They should be able to advice and counsel clients and other stakeholders on the benefits of BIM. Building professionals may maximize the environmental performance of structures across their lifetimes and make well-informed decisions by integrating sustainability concepts into the BIM process.

The construction sector is a key component of a nation's gross domestic product, but its inherent nature results in potentially dangerous conditions that affect the safety of all workers on construction projects (CPs). Therefore, the original idea of the research is to determine the relationship between safety system (SS) during the implementation phase (IPh) of CPs and the minimisation of waste (materials, time and cost). Achieving a lean construction work requires suitable planning, safety considerations and waste resource minimisation throughout the project cycle. This research aims to identify and rank the safety factors during the IPh of a CP, which will have positive effects on minimising waste. Information and data were gathered from the existing literature and the structured interviews and questionnaire survey conducted among 111 randomly selected construction companies. Questionnaire results were evaluated using statistical tools, such as hypothesis testing, analysis of variance and linear regression. This research identified and ranked 24 important safety factors with positive effects on minimising waste in CPs during IPh. The seven most important safety factors that should be considered to minimise material, time and cost wastage are as follows: handling, management, external factors, workers, procurement, site condition and appropriate scaffolding for SS. The best linear model was developed on the basis of the importance index of the identified factors. This model can predict the minimisation of waste (materials, time and cost) in CPs by using SS. Thus, the safety criteria and SS should be used during IPh to minimise waste on the basis of the developed model. [ABSTRACT FROM AUTHOR]
