Xinzhuang TODTOWN, Shanghai

A mini-city well connected by various rail and road networks

In Shanghai’s southern suburbs, the Xinzhuang Metro Station is being transformed into a destination in its own right – a multi-mode transport hub integrated with extensive retail, office, hotel and residential facilities.

Arup is providing structural engineering services to realise this well-connected yet highly complicated mini-city on top of numerous metro lines (the existing Line 1 and Line 5 and the planned Line 17), bus terminals and railways including an inter-city high-speed rail.

Project Summary

1st in China to expand an existing station in operation into a new mixed-use development

With a total GFA of 740,000m², the development comprises one office tower, one 5-star hotel tower, a collection of high-rise, mid-rise and multi-storey residential buildings, and a 120,000m² luxury shopping mall. Designed in three phases, the whole project is scheduled for completion in 2022.

The major technical challenges to structural design involve the building safety, service continuity and occupant comfort with trains directly running below. This is further complicated by the need to address seismic actions.

A moment frame system was chosen for the structure astride the railways and supporting the large deck. A moment frame-sheer wall system and base isolation were adopted for the buildings above the deck which is composed of a combination of sliding bearings, rubber bearings and viscous dampers.
