Qingdao Ocean Tower

Qingdao Ocean Tower

Reaching New International Heights: Engineering 60 stories of office space

With 60 stories of office space, this high-rise tower adds a new element to the skyline in Qingdao, China.  DCI’s structural services involved the design of this single office tower, which is part of a larger three-building development.

Project Highlights

  • The tower contains retail and office space.
  • Includes three levels of underground parking.
  • A tunnel connects the DCI-designed underground parking with the below-grade parking in the other two buildings.
  • Design complied with international standards. 

Case Study

DCI Engineers provided structural engineering design and consulting services on the Ocean Tower, an 800-foot high-rise office building in Qingdao, China. The development contains five-story podium shopping mall and more than 100,000 square meters (1.15 million-sf) office space.

The gravity system is composite steel floor framing with concrete on metal deck. Due to the heavy axial load from the high-rise, we used steel pipes filled with high strength concrete columns. The lateral system included a concrete shear wall core. China’s building code requires “core-in-core” systems for this super high-rise. An exterior steel moment frame was added to satisfy the code. The structural challenges also include below-grade parking levels that are under a water table. Bottom floor columns transfer at the lobby level to provide open spaces.

DCI worked closely with Living Architecture Inc. (LAI) as part of the multi-national design team. We met with the LAI Seattle office architects on a daily basis to coordinate structural elements with the building program and architecture. We traveled to China to help the LAI Beijing office prepare design documents for submittal and to participate in the peer review conference with the owners and government officials.

DCI is familiar with both American architectural design and Chinese building code requirements. DCI provided exceptional service to the architects and the client. The project was transferred to the local design institute (Tong-Yuan) after Design Development. The design team successfully completed the project design and coordination. The project is now under construction.

青岛国际航运中心位于青岛CBD核心区,连云港路和敦化路圆形城市广场的东南方。项目包括一栋56层的超高层办公楼,附属的5层裙楼商场,以及地下4层配套设施楼层,其中地下一层为商业,地下二层为设备用房及员工食堂,地下三层及地下四层为停车库。超高层办公楼建筑总高度250米。

主体结构采用压型钢板现浇钢筋混凝土组合楼板,型钢梁,钢管混凝土外框柱。抗震抗风横向系统,根据中国现行超高限规范筒中筒结构。利用中心电梯核心筒及外框架控制结构位移。

我们与北京都市光影(LAI)西雅图分公司建筑师密切配合,确保建筑设计符合结构要求及满足中国规范。当建筑师和业主需要,我们多次飞往中国,参与设计文件提交及超高限专家会审,业主和政府部门报告。

DCI既熟悉美国建筑设计也深入了解中国现行规范,我们为建筑师和客户提供了无可比拟的卓越服务。该项目在通过专家审核及扩初设计后,已移交本地设计院(济南同圆设计院)做施工图设计。目前该项目正在顺利施工中。
