Development and preparation

The London Organising Committee of the Olympic Games (LOCOG) was created to oversee the staging of the Games after the success of the bid, and held its first board meeting on 3 October 2005.[31] The committee, chaired by Lord Coe, was in charge of implementing and staging the Games, while the Olympic Delivery Authority (ODA) was in charge of the construction of the venues and infrastructure.[31] The latter was established in April 2006.[32] The Government Olympic Executive (GOE), a unit within the Department for Culture, Media and Sport (DCMS), was the lead government body for coordinating the London 2012 Olympics. It focused on oversight of the Games, cross-programme programme management and the London 2012 Olympic Legacy before and after the Games that would benefit London and the United Kingdom. The organisation was also responsible for the supervision of the ?9.3 billion of public sector funding.[33] In August 2011, security concerns arose surrounding the hosting of the Olympic Games in London[34] due to the 2011 England riots, with a few countries expressing fear over the safety of the Games,[35] in spite of the International Olympic Committee's assurance that the riots would not affect the Games.[36] The IOC's Coordination Commission for the 2012 Games completed its tenth and final visit to London in March 2012. Its members concluded that "London is ready to host the world this summer". The London Organising Committee of the Olympic and Paralympic Games (LOCOG) is the organisation responsible for overseeing the planning and development of the 2012 Summer Olympic and Paralympic Games. It was jointly established by the UK Government's Department for Culture, Media and Sport, the Mayor of London and the British Olympic Association and was structured as a private com any limited by guarantee.[1] LOCOG worked closely with the publicly funded Olympic Delivery Authority (ODA), which is responsible for the planning and construction of new venues and infrastructure. On 6 July 2005 the International Olympic Committee (IOC) chose London as the host city for the 2012 Olympic Games, narrowly beating the Paris bid. After the success of the London bid, LOCOG was formed to continue the work started by the bidding team. LOCOG was officially designated as the organisers of the Games at its first board meeting on 7 October 2005. The Olympic Delivery Authority (ODA) is the non-departmental public body[1] responsible for ensuring delivery of venues, infrastructure and legacy for the 2012 Summer Olympic and Paralympic Games in London. Along with the London Organising Committee for the Olympic Games and Paralympic Games (LOCOG), the ODA is one of the two main agencies organising the London Olympic Games. The ODA was established by the London Olympic Games and Paralympic Games Act 2006 and is the responsibility of the Department for Culture Media and Sport. In advance of the formal establishment of the ODA, the London Development Agency (LDA) and Transport for London (TfL) were asked to undertake the development work necessary for the Olympic Park and the transport infrastructure which will service the Games, and to build up an interim team. The ODA is based alongside LOCOG at One Churchill Place in Canary Wharf. The ODA has appointed a delivery company, CLM, to manage the delivery of the Olympic Park and its associated infrastructure. CLM is a consortium of CH2M Hill, Laing O'Rourke and Mace. CLM's organisation includes teams responsible for the design and construction of the venues, structures bridges and highways as well as logistics and security.
