[11] Construction of the velodrome was marred by many issues and controversies, which included numerous delays, poor working conditions and financial difficulties.
[13] Mayor of Rio de Janeiro Eduardo Paes admitted in December 2014 that work on the velodrome was three weeks behind schedule,[14] 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.
In April 2015, construction was temporarily suspended by Brazil's Ministry of Labor and Employment, claiming a "grave and imminent danger to the physical safety of workers.
"[19] The ministry cited their concerns for "the absence of collective protection", and risk of workers falling, in addition to lack of security, no technical report on the stability of slopes at the site, and what was described as a potentially hazardous "accumulation of material".
[22][23] It was by then that President of the UCI Brian Cookson made public his concerns about the completion of the venue, bluntly stating to the media, in a press conference after the 2016 UCI Track Cycling World Championships, that completing the venue in time for test events in late April was "a challenge", and that "if the velodrome is not ready in time, there is no plan B.
[25] The Organising Committee cited "logistical problems" with the import of raw materials from Serbia; the wood arrived late into Rio's summer, and the city's high humidity meant that the sensitive surface could not be laid as quickly as expected.
[28] The municipal government of Rio de Janeiro cancelled the contract with Tecnosolo shortly afterwards, saying in a statement that the company "did not have the conditions to continue being technically responsible for the construction of the velodrome".
[32] The venue's opening was not without controversy, however, when state prosecutors inquired about the selection of Engetécnica and subcontractor company Zadar for construction and operation contracts, without a proper bidding process.
[32] After the Olympics, the velodrome spent time closed due to two roof fires in June and November 2017,[34] and further damage caused by a storm in October 2018.
