Abstract—Enormous amount of waste comes from construction works every year in various municipalities globally. Previous works has given much attention to wastes that are seen, such as excess materials that are not used on site, wastes from materials that are damaged during handling, wastes that are generated while trying to cut a material to fit the required size, etc. Meanwhile, wastes from the design may not be very obvious to the owners and to some site workers. This study reviews a design of a building using three different orientations of some of the wood components (roof panels, joists and beams). Using WoodWorks software, the volume of wood required for the construction of some building components were evaluated. A quality control of the result was done through a ‘manual verification’. Where applicable, manual calculations override the results of the software. The study presents design results for roof panel, joists, beams and columns. The result showed that the orientation of wood sections affects the volume of wood that will be required for a building. The volume of wood used in construction is dependent on the design of the building. Designers need to check various orientation and support conditions to evaluate opportunities for savings/optimization of materials.
