The project involves the collaboration of a global Transforming Work Processes team, including: Early on, the owner engaged Autodesk Consulting • Shanghai Tower Construction & Development— to provide BIM strategy and implementation Autodesk Revit provided owner/developer consulting services, as well as application training. a common platform for • Gensler—design architect Autodesk Consulting began its effort by helping • Architectural Design and Research Institute of the owner develop a BIM strategy and deployment our design partners, Tongji University—local design institute plan for the project, and retooling design and giving the team a more • Thornton Tomasetti—structural engineer construction workflows to support BIM-based • Cosentini Associates—MEP engineer processes. The team created detailed plans for accurate representation • Shanghai Construction Group—general contractor project collaboration and document management, and deeper understanding • Shanghai Installation Engineering—mechanical as well as defining the BIM deliverables for the and electrical general contractor entire project lifecycle. of the project. • Shanghai Xiandai Engineering Consultants— design management consultant Autodesk Consulting also helped the owner —Jun Xia • Autodesk Consulting—BIM strategy, training, and implement an on-site BIM application Principal and implementation consultant environment for a local project team of over Regional Design Director 50 members, including owner personnel and Gensler “Because Shanghai Tower is such a complex key project participants from the extended building, it could not be represented accurately global project team. In addition, Autodesk with typical software or design methods,” says Consulting provided software training and Jiliang Chen, deputy chief architect and deputy ongoing technical and BIM coaching support. “We used Revit Architecture software to design director of the project operations department at “By combining Autodesk’s BIM technology and model the tower and then shared those the Architectural Design and Research Institute and the deep expertise of Autodesk Consulting, models with our mechanical, electrical, and of Tongji University. “One of the most challenging we have been able to successfully transition structural consultants,” explains Michael Peng, issues is the coordination of the extended design to BIM much faster.

In the construction phase, Revit® Architecture, Autodesk® Revit® Structure, the local project team, working from temporary and Autodesk® Revit® MEP software for the tower’s offices near the construction site, routinely design and documentation. The team is also using shared its models for project coordination and Autodesk® Navisworks® Manage software for collaboration. This communication of design data coordination and collaboration, Autodesk® Ecotect® resulted in a natural coordination of the project Analysis software for sustainable design analysis, as it unfolded. In addition, the team used both and traditional AutoCAD® software for drawing Revit and Navisworks Manage software for formal production. “From a property owner’s perspective, clash detection. BIM provides an excellent tool for the design, construction, management, and investment control of the entire project,” says Gu.
