Rio 2016's volleyball venue was subject to emergency repair work on Thursday and Friday, after issues with the court floor were reported.
The women's volleyball tournament at Rio 2016 began as scheduled on Saturday, but only after emergency repairs to the court in the Maracanazinho.
Officials found defects in the floor of the court on Thursday - following three days of team training at the venue - and duly worked through the night and into Friday morning to ensure sufficient stability.
Richard Baker, the communications director of the International Volleyball Federation (FIVB), said: "After the women had trained there was no problem. But after the men had trained there were areas on the court that needed strengthening.
"The court was taken up and extra strengthening put in place and tested out. It was quite a job and went on through the night.
"This is not something that usually happens and was a concern.
"But it's why we have teams training on the court, for them to get practice and a feel of the court and for any problems to show up. So in that sense everything worked out.
"Now we are happy that what promises to be an exciting tournament is up and running."
Six pool matches were scheduled for Saturday, with hosts and two-time reigning champions Brazil opening their campaign against Cameroon at 3pm local time (7pm BST).
