Abstract: By two years of technical training and the accumulation of experience, several typical project have been completed that from the start of design to operational.Designers have masted 3D design skills and experience, including Pipeline Integration, Building Energy Analysis and Virtual Roaming.BIM Center gathered BIM project implementation experience gradually, and sought a way that best BIM collaborative design solutions in the traditional design. Combined the Jiuquan project, this paper explored the relations and significance about the model of design and estimate, discussed the feasibility of project practice and analyzed its application value.
