Precision Control of Special-Shaped Pillar Construction Based on BIM Technology

Using the BIM information model to Zhengzhou riverside international new city by the south the eight-channel Chaohe river bridge project design and project management. Through the establishment of information model for aliens pillar of the template design,drew a detailed pillar construction template,with information model to guide pillar construction lofting measurement,improved the pillar linear control accuracy and reduced the measurement deviation,which could make the design train of thought to express to all project personnel joining into the detail,and then improved work efficiency. The information model can be material statistics and the management of the construction progress.
