what changes were made to the london olympic stadium
London Stadium Dennis Hone, chief executive of the LLDC, revealed in November 2012 that the stadium would not meet its reopening deadline of 2014. Instead the stadium would reopen in August 2015 with the stadium retaining a capacity of around 50,000 for athletics.[47] Following the granting, in March 2013, of a 99-year tenancy to West Ham United, the E20 LLP, a joint organisation by the London Legacy Development Corporation and Newham Council were specifically set-up to oversee redevelopment of the stadium into a UEFA Category 4 venue seating 60,000 spectators. The reconfiguration saw work on a new roof, corporate areas, toilets, concessions and retractable seating. West Ham contributed £15 million and Newham Council £40 million for the work to be carried out with the LLDC and the British Government making up the rest.[48][49] Approval was granted for the installation of retractable seating on all sides of the stadium and an 84-metre (92 yd) transparent roof.[50][51]
