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. -
