Several projects planned for Beijing have been reviewed after the collapse of Terminal 2E at the Charles de Gaulle airport in Paris.
A source in the region said checks had been made on structures such as the Olympic stadium, designed by Herzog & de Meuron, Arup's Olympic swimming pool and Rem Koolhaas' Central Chinese State Television headquarters.

The source said: "The Chinese government is questioning things closely – it obviously doesn't want any embarrassment in the future. It's a gut reaction to what happened in Paris in May."

The source said he did not see the reviews as anything more than a "blip in the process", pointing out that the three buildings are fundamentally different from the Paris terminal.

The accident gained a higher profile in the region as the terminal's architect, Paul Andreu, who also designed the Beijing national theatre project, was in Beijing at the time.

A spokesperson for Koolhaas' Office for Metropolitan Architecture said the CCTV building had been subject to review. He was confident that construction would start this year.

A spokesperson for Arup, which is structural engineer on the stadium and the CCTV building, said the firm was unaware of specific reviews following the Paris collapse. She added that the CCTV building had passed tests for structural building codes.
