The London 2012 Olympic Stadium is set to undergo a makeover with specialist contractors being invited to bid for a roof conversion job.

Officials behind creating a lasting legacy following the Games in the UK have started the race to land the contract which will be decided in December. The Construction Enquirer reported that a notice published by the Official Journal of the European Union (OJEU) is the first specialist package for the stadium and is expected to cost a total of £150 million when completed.

Companies have until the end of the year to submit their applications for the conversion project and construction is due to begin sometime after the announcement.

The future of the Olympic stadium in Stratford has been a hotly-debated topic with a number of football clubs applying to move into the ground when the Games came to a close in August 2012. West Ham United were able to fend off competition from Tottenham Hotspur and League One side Leyton Orient to claim the status of preferred bidder. However, there could be some issues in the coming years as the club is still in the process of arranging funding to pay for the conversion.

Officials at West Ham have stated that they would not be relocating to Stratford until 2016 at the earliest as they make the stadium ready to play Premier League football. There will be a number of interim events including athletics meetings and concerts. Promoter Live Nation is already signed up to host a series of shows in 2013 to rival previous events it has held including Bruce Springsteen and Rihanna.

John Reid, president of concerts at Live Nation Europe, said: "We are delighted to be staging music concerts at the London Olympics venue, which last year became a globally-recognized site for outstanding performances – both in sport and music."

There is currently no value on the roof and associated steelworks package for the ground but it will be able to become a "multi-function venue" once converted.
