London's final plans in support of the bid to host the 2012 Olympic Games have arrived at the International Olympic Committee's headquarters in Lausanne.
Amber Charles, a 14-year-old basketball player from East London, handed over the 600-page document on Monday.
IOC officials will scrutinise the plans from London, Paris, Madrid, New York and Moscow before producing a report.
"Every aspect of our ability to stage the Games is in that file," London bid leader Sebastian Coe told the BBC.
IOC members will also visit the cities vote with voting for the winner at their congress in Singapore on 6 July.
The IOC team will spend four days in each city, visiting London from 16-19 February.
All five cities were required to submit their bid books by the IOC's Monday deadline - and are not now allowed to make any further submission.
Coe was confident that the contents of the dossier would make impressive reading for the IOC.
"We've worked extremely hard on this," said Coe.
"The IOC will study it and drill down into it, and will visit in two or three months to go through it in detail," he said.
"We've got a team that has thought about nothing else for the last week.
"It's in good shape. I think it's unique and really differentiates us from the other cities.
Amber, who has already been capped for England Under-14s basketball team, had been looking forward to handing over the 11lb file.
She said: "I'm excited but I'm nervous about handing over the bid book - I think I might drop it.
"I'm hoping to compete in 2012 so the Olympics being in London would make it easier and more exciting."
The document was also accompanied on its journey by a fish-eye BBC television camera.
Taking 10 months to produce and printed in both English and French, the file will be sent out to all 128 IOC candidates.
It had to provide detailed financial costings and cover 17 specific themes including plans for marketing the event, environmental impact and ideas about the legacy to the local area.
Paris is the favourite to win hosting rights after coming out on top when the shortlist of bidding cities was whittled down to five in May.
The IOC ranked Madrid second ahead of London, New York and Moscow.
Domestic support will be a big factor - and a survey by BBC Radio Five Live reveals that while 75% of the UK population is backing London's bid, that is lower than Paris, Madrid and Moscow.
London's plans are based on an Olympic zone around Stratford in the east of the city.
Wembley, Wimbledon, Lord's, the Dome and Hyde Park will also be used as venues, with beach volleyball planned for Horse Guards Parade.
The IOC report in May questioned London's transport network, the spread of its venues and levels of public support for the bid.
But London's bid team are confident their latest plans will stand up to scrutiny, with Coe dismissing reports that London is still in third place behind Paris and Madrid.
"I've seen three or four polls with London in all sorts of positions," Coe told BBC Sport.
"The only poll that matters is the one in July. What we have in our control, we have done very well."
Paris plans to use the Stade de France as its Olympic stadium, having staged the 1998 World Cup final and 2003 World Athletics Championships there.

Its other venues include Roland Garros, the Parc des Princes and beach volleyball beneath the Eiffel Tower.
Madrid is promising an environmentally friendly Games, while New York is planning to use Yankee Stadium, Flushing Meadows and Madison Square Garden among its venues.
Moscow, which received the least flattering assessment from the IOC in May, says it will host a compact Games, with all sports within the city limits.
