Automation of Quantity Takeoff and Material Optimization for Residential Construction Manufacturing

  • Author / Creator
    Zhao, Hongru
  • Quantity takeoff is repetitive work in the modular construction industry. The
    current process, which is typically carried out manually, is time consuming and
    error-prone. This thesis proposes a methodology to automate the quantity takeoff
    process. The central aim of this research is to create a bridge between the building
    information modelling (BIM) 3D model and a database that can be used to hold
    data extracted from the model. This bridge allows the automatic transfer of
    material quantities from the BIM model to the database. Another issue associated
    with residential construction is material waste, especially for 1D and 2D framing
    materials, which is caused by insufficient planning of cutting processes. Hence,
    this thesis also presents a methodology to optimize material usage (focusing on
    lumber and sheathing). 1D and 2D materials are extracted from the BIM 3D
    model and then organized in order to establish optimized lumber and sheathing
    cutting plans.
