Builders in hard hats were on Tuesday dismantling temporary seats towering above the pool where American Michael Phelps won a record 18th Olympic gold in August.
However, the failure to settle on a tenant for the centrepiece Olympic Stadium, built at a cost of some £430 million, has taken some of the gloss of a successful Games that silenced the sceptics.
West Ham United remain the most likely tenant but wrangling over the division of the costs of turning the stadium into one also suited for top-flight football has slowed the process.
The London Legacy Development Corporation, the public body responsible for the site, is scheduled to discuss the stadium issue again next week and there are hopes that a decision will be announced before the end of the year.
However, the LLDC has warned the stadium will not open before 2015, prompting a frustrated UK Athletics Chairman Ed Warner to denounce the delay as a farce.
The Olympic Stadium will hold the 2017 World Athletics Championships and is on the list of potential venues to host matches during the 2015 rugby World Cup but that deadline is beginning to look tight.
The Games cost the British public around £9 billion and spending during the Olympics helped to give a one-off boost to Britain's struggling economy.
London has restarted free bus tours around the Olympic Park, keen to maintain the goodwill generated by the Games and show that it will have a viable future as part of plans to regenerate what was long a rundown part of east London.
Workers on the site on a bleak November day were focused on getting it ready to reopen to the public next July - a year on from the Games - with a new name of the Queen Elizabeth Olympic Park.
"We want the park to open as quickly and as safely as possible," Colin Naish, director of infrastructure at the LLDC said, adding the target was for a phased reopening to be completed by the middle of 2014.
Contractors Balfour Beatty and BAM Nuttall are expected to employ up 1,000 workers on the conversion.
The swimming pool is scheduled to be used as a public leisure centre from 2014, although London has also bid to stage the European swimming championships at the venue in 2016.
Britain is seeking to build on the good publicity generated by the Olympics to attract lucrative international events.
It has also applied to stage the 2016 world track cycling championships on the London site.
