Abstract:
Typically, construction can cause a large amount of waste from various processes, adversely affecting the environment. Besides, waste management is considered as one of the projects burden costs. For this reason, proper waste management is ignored. In addition, facilitating method or tool for measuring the amount of waste in the construction process has not yet implemented. Therefore, this research aimed to present the system that is able to determine the amount of construction waste using digital images and 3D model. In this research, the system was developed using the sample materials with known volume. This research used a mobile phone camera and programs to analyze the volume from a 3D model. The developed system was then tested with construction waste obtained from the housing project, consisting of lightweight concrete, red bricks, concrete, floor tiles and roof tiles. Furthermore, the system was then redesigned to enable determining the amount of construction waste faster by using images from video. The analytic results indicated that the error of the test results belongs to the 95 % limit of agreement method of the group of results. However, the system still has limitations in determining the amount of waste because many steps still require labor skills to improve 3D model. In sum, the findings would be beneficial for further construction project in determining the amount of construction waste towards the well-organized waste management according to their types.
