Abstract
Multi-dimensional graphic technology is mostly used in the visual display in the field of civil engineering currently, but applications on other projects practice are few. Because there is no standard and systematic protocol to follow, it is usually inefficient and time-consuming to apply the multi-dimensional graphic technology into the material procurement in construction projects. This research tended to apply lean procurement into the materials management and facilitate the procurement management to avoid the waste cause by inaccurate procurement. This research combined 3D images characteristics with lean procurement to create a procurement management model for project manager. The steps of building this model are: (a) Developing a graphical framework which is called Object Block Work Breakdown Structure (OBWBS) based on Work Breakdown Structure (WBS) (b) Decomposing the hierarchy structure of OBWBS to produce the smallest 3D graphical unit with relevant material properties (example: the information is needed by the bill of material, such as number and models, etc. ) (c) Constructing basic structure and implementation process of the database associate with graphic correlation of OBWBS and work relationship of WBS to achieve the goal of systematic procurement management. By applying the graphical database which consists of graphical components and material properties, project manager can easily realize the bill of material and other procurement information. Furthermore, establishing reusable template through accumulation of different projects data can provide construction companies with accurate calculation related to the procurement of materials on similar type of building, it be able to save a lot of time and cost of projects in the future.
