Application of building information modelling for reinforcement waste minimisation

The primary objective of this paper is to explain how successful implementation of building information model/modelling (BIM) can contribute to the reduction of waste in construction projects. Traditional construction processes include highly wasteful activities due to lack of automation and innovation. This paper discusses how reinforcement information can be efficiently managed through BIM to maximise coordination between project parties and using three-dimensional digital models at the site for fabrication and construction. The digital reinforcement modelling process is gaining momentum due to a great number of value additions to achieve potential savings at all stages of the project. This paper also focuses on collaboration, such as integrated project delivery to streamline the project processes and workflows to achieve greater efficiency, and de-risking the construction processes. These BIM approaches can reduce, reuse, recycle and manage the wastes generated during construction through a robust clash-resolution process, data-rich modelling, detailing and prefabrication strategies. The key benefits of BIM are to ensure 100% buildability and provide cost-effective solutions through modern approaches such as value engineering and early contractor involvement. The digital fabrication process can be used to automate the reinforcement fabrication process by establishing a link between the fabrication system and BIM models.
