Abstract: This paper presents virtual design, virtual construction and Engineering quantity of building information modeling (BIM).BIM has the advantage over the traditional 2D CAD technology in improving the collaboration and the construction productivity among those who participate in the projects. Moreover, the building cost is saved by using BIM technology by the reduction of design and construction errors in the early stages and reduction in time required to complete the construction. Application of BIM technology in Beijing facilitates the design and the construction of the building, a computer-based 3D model is built virtually and helps engineering in construction, scheduling, planning and cost estimates.
