 As with every track cycling venue purpose-built for the Olympics since the 1960 games, the Rio Olympic Velodrome faced cost overruns by its final year of construction.Olympic Games Executive Director Gilbert Felli warned as early as November 2014 that the velodrome had become a concern for the International Olympic Committee (IOC) – the venue was originally planned to be complete by the end of 2015, but delays had organizers worried that it would not open until early 2016 instead, despite the UCI pressing that this would not be the case.Mayor of Rio de Janeiro Eduardo Paes admitted in December 2014 that work on the velodrome was three weeks behind schedule, and evaluations by the IOC in February 2015 found that substantial work still remained in order for the venue to be complete by scheduled test events prior to the Olympics, describing "very aggressive timelines that will need to be met over the coming months."
