Abstract: This paper presents the state of the practice in the application of Building Information Modeling (BIM) technology in the residential building development project. The current BIM application is the visualization of the excavation requirements based on the design drawing and cannot provide a refined guidance for the construction management. The current visualized earth excavation model is further developed and deepened for the accurately determining the locations of building alignments, water collection pits and elevator locations. After the visualization model been reviewed and approved by the experts, shop drawings are then produced and then served as the construction guidance. This visualized BIM model has the characteristics of multi bottom of water collection pits elevations and excavation pits within the pits. These locations are positioned by using the CADD insertion function in the BIM software and are efficiently projected on the site by using the GPS total stations.
