BIM on Construction Waste Reduction: A Comparative Study of Traditional and BIM-Enabled Construction Projects

The study aimed to determine whether to utilise building information modelling (BIM) instead of tried-and-true methods for cutting down on waste on construction sites. The role of building information modelling (BIM) and sustainable construction factors (SCF) in influencing the diffusion of environmentally friendly building methods is investigated. Quantitative methods are used to examine the data gathered from the surveys and the construction projects. Analysis of the data used both inferential statistics and more descriptive methods. By calculating the route coefficient from BIM to SC, study see that the variables in BIM and SCF are positively related in a big and statistically significant way. To back up the quantitative research approach, case study is analysed: the Royal Liverpool University Hospital Project. Collecting and analysing data showed a strong relation between BIM use and eco-friendly building methods. Supply chain financials (SCF) have also shown a strong correlation with SCMF, demonstrating the importance of efficiently organized supply chains in reducing waste and enhancing sustainability in building projects. Since BIM improved both design and planning, it also improved project-wide communication and collaboration. Increases in waste minimization and resource efficiency, as well as other sustainable construction results, may be the result of enhanced communication among project stakeholders. In addition to advancing the sustainable building industry, the research demonstrated that waste in construction may be reduced via the use of BIM and effective SCM approaches. Further research was conducted to identify potential moderators of green building. In the past, design changes have an important impact on the final product of a green building project, but with the use of BIM, these alterations could be managed with little influence on the project's
overall sustainability objectives. Financial variables, such as available cash and priority given to other building demands, determined the amount to which eco-friendly construction approaches were used. Using SCM
techniques, businesses were able to better manage their finances and thus move closer to their sustainability goals. Wasteful construction site material management was the last nail in the project's coffin. These unfavourable results
might be mitigated using BIM and effective SCM procedures, making for greener building endeavours.
