Developing a BIM-based technique in the design phase to achieve sustainability in residential building projects

The building construction industry is one of the industries that contribute most to waste production in the world. Therefore, the efforts of researchers focused on reducing construction waste (CW). The building design stage is a decisive factor in the formation of waste by determining the sizes and dimensions of the elements and the resulting formation of some remains (waste) that may become a resource added to the project resources if this process is planned in advance. The absence of this planning may lead to it becoming waste. In our research, we present a BIM-based model for reducing floor tile construction waste in multi-story residential buildings, which contributes significantly to achieving sustainability standards in construction projects. Tartous housing projects -in the Sheikh Saad complex project were chosen as a case study, which consists of 20 residential towers with 16 floors, each floor containing 8 residential apartments. The Revit program was used to model buildings, and Dynamo to design a technique to reduce CW in the design stage, by comparing different sizes of floor tiles using visual programming techniques. We chose the floor tile size that achieves the lowest value of waste throughout the entire project. High reduction rates were reached, amounting to 96.43% (of the actual waste in the project) compared to the current traditional design, which is a very promising percentage in the field of reducing the formation of construction waste and achieving sustainability standards.
