Comprehensive Analysis of BIM Technology Implementation at Alibaba Headquarters in Shenzhen

1. Project Introduction
The Alibaba International Operations Headquarters and Business Cloud Computing R&D Center are located in Shenzhen. The complex consists of three basement levels and four towers, with the tallest building reaching 17 floors above ground. The total construction area spans 120,000 square meters. Architecturally, the entire structure forms a block shape that resembles a “cloud” floating over Shenzhen Bay.

2. BIM Team Resources
To effectively incorporate BIM technology into the various management activities of general contracting, a dedicated BIM management department was established within the project’s general contracting management structure.
