Construction work on the Barra Olympic Park, the heart of Rio 2016, is continuing to progress with the three Carioca Arenas showing the most development.
Competition areas have already been concreted and the initial structures for the spectator stands are in place, providing glimpses of what it will be like when the world's best athletes battle for medals there in less than two years' time.
During the Games, the three venues, previously known as Olympic Halls one, two and three, will host four Olympic sports - basketball, judo, fencing and taekwondo - and four Paralympic sports - wheelchair basketball, wheelchair rugby, boccia and judo.
"We have been working very hard to ensure that the venues are designed to meet all the requirements for hosting top-level sports competitions and we are very pleased to see the buildings leave the drawing board and become reality," said Josué Moraes, Rio 2016's sport group manager for taekwondo and judo.
"Now it is possible to envision how they will be operated during the Games."
Work is most advanced on Carioca Arena three, where the stand structure has been completed and work is underway on fitting the steel support structures for the roof.
While the Olympic Park's nine competition venues will host 24 sports, the site will also be home to two important venues for ensuring that fans all over the world can enjoy the Games, the International Broadcasting Centre (IBC) and Main Press Centre (MPC).
Work on the steel frame and concrete levels of the IBC are in the final stages while the foundations of the MPC have been completed and structural work is pressing forward on the basement, ground floor and mezzanine.
Work on the Olympic Tennis Centre's centre court's spectator stands, which will hold 10,000 people, is progressing well too and the preparatory earthworks for the other courts has been completed, ready for surfacing.
"Significant progress has been made and we are happy to see that work is proceeding as planned, and in some cases, is ahead of schedule," said Alexandre Techima, Rio 2016's infrastructure integration director.
"Venue construction has progressed a lot over the past few months and the structures of a number of arenas are already visible, such as the Carioca Arenas and the Olympic Tennis Centre, as well as the IBC, MPC and hotel."
Work on the general infrastructure inside the Olympic Park is also progressing well, Rio 2016 claim.
More than 10.5 kilometres of drainage, 5.3km of sewage system, 8.3km of water supply lines, 5km of fire prevention lines, 5km of lighting, 9.9 m of medium-voltage grid and 21.9km of telecommunications lines have been installed.
Meanwhile, the foundations of the Future Arena, the temporary venue that will host the handball and goalball competitions, are nearing completion.
Work on the Arena's steel structure is already under way, with the pillars and beams being installed.
One of Rio 2016's main social legacies, the Arena will be dismantled after the Games and its parts will be used to construct four public schools in the host city.
The Rio Olympic Arena and Maria Lenk Aquatic Centre, which have been operational since 2007, are scheduled to undergo modifications in the first quarter of 2015.
Furthermore, foundations are being laid for the Rio Olympic Velodrome and Olympic Aquatics Stadium.
The Olympic Park works are being coordinated by the Rio Municipal Government.
