Structural Strengthening -westfield, London

摘要

London has a dramatic new shopping and leisure complex - Westfield London. Situated at the heart of the massive regeneration of the Shepherd's Bush and White City area of west London, the scheme - boasting five anchor stores and over 265 top high street retailers - also has nearly 50 eating places. The superstructure phase of this prestigious building began in early 2005 and Westfield London opened for trading in November 2008.rnThe structural frame of the complex, which totals approximately 300,000m~2, contains over 105,000m~2 of post-tensioned concrete slabs.rnWith most construction projects, there are always minor changes to be expected along the way. On this particular project there was a change in both ownership of the development and the main tenants renting space. The change in tenants required considerable design modifications to the structure to accommodate their additional requirements. This included increased loads and many small, and 17 larger, penetrations to various areas of the already completed structure.
