RIO DE JANEIRO, Brazil (AP) — Local organisers worked yesterday to assure IOC inspectors that Rio’s 2016 Olympics, plagued by delays and concerns about hotel space and transportation, are on course after a slow start.

The IOC coordination commission, led by former hurdles champion Nawal El Moutawakel, will wrap up its tour today. It’s the inspectors’ fifth trip to Rio to check progress.

Several coordination commission members have been outspoken about forcing Rio organisers to speed up games preparations. During the last visit six months ago, IOC Executive Director Gilbert Felli said: “We don’t have any yellow card to send to Rio.”

A warning this time would be major embarrassment to local organisers, and recall the 2004 Olympics in Athens, when then IOC President Juan Antonio Samaranch issued a “yellow card” reprimand to Greek organisers.

The widely circulated Brazilian newspaper O Estado de S Paulo, citing what it said were confidential IOC documents, said Saturday that phases of the Rio Olympics were at “serious risk” because of construction delays, a shortage of hotel rooms andmyriad of related problems.

The newspaper, which did not say how it obtained the documents, said only half the games projects were on schedule. It said the IOC rated progress into three categories — red light, yellow light and green light. It said the IOC listed infrastructure projects in the red category — meaning behind schedule.

Citing the document, the newspaper said the IOC was concerned about progress on a 16-kilometre (nine-mile) subway-line extension into the Barra area — the centre of the games. It also said there were problems with a port redevelopment plan and plans to upgrade Rio’s run-down airport.

Another problem area cited was the Deodoro Olympic Park, one of four core areas for the games. Plans to renovate this run-down northern part of the city are far behind schedule. The area will host equestrian events among others.

The paper said the IOC document showed Rio had lined up only 19,200 hotel rooms, when about 45,000 are required. It also said organisers were having problems lining up cruise ships to dock in the port area and provide extra hotel space.

The document also said that projects dealing with water supply and electricity had to be monitored.

In a statement to The Associated Press, the IOC acknowledged it produces various documents to monitor games progress. It said this was not unique to Rio.

“In a project of this size and complexity, it’s standard for organising committees to have different colours during the preparations and some may even remain red right up until the end of the preparation period… although they will be delivered in accordance with what was planned.”

This is a challenging moment for South America’s largest country, which is trying to organise two

mega-events and is facing pushback from citizens who question spending so much on sporting events, particularly in a country with vast inequality, high prices and a slowing economy.

Brazil is spending about $13.3 billion of largely public money on next year’s FIFA World Cup. Olympic organisers are expected to announce their budgets in a few months, but public spending could be similar to that on the World Cup — or higher.

Leo Gryner, chief operating officer of the Rio games, acknowledged in a recent interview with The Associated Press that organisers got a “six to eight month” late start on building venues.

Gryner said that $700 million in public money may be needed to balance the operating budget. This is the budget to run the games themselves and is expected to be as much as $4 billion when it’s announced. He said any shortfall was due to inflation, the sluggish economy and a struggle to sell local sponsorships.

Gryner said the capital budget — a mix of public and private money aimed at building supporting infrastructure for the Olympics — could be 35 per cent above the $11.6 billion listed in the original bid.
