Sao Paulo, Oct 10 (IANS): Brazil's Olympic Committee president Carlos Nuzman says preparations for the 2016 Rio Games are on track despite concerns over delays in key infrastructure projects.

Nuzman told a Sao Paulo Industry Federation (FIESP) conference Tuesday that works in Rio were within the "specified time frame".

"We are on track, whether it be for infrastructure or sports facilities," Nuzman was quoted as saying by Xinhua.

During the event FIESP announced the creation of a working committee to discuss business opportunities that can be of mutual benefit to local companies and Games organisers.

Despite Nuzman's assurances, FIESP vice-president Jose Carlos de Oliveira Lima said he was concerned at the slow pace of preparations.

"The infrastructure works for 2016 are already behind schedule," Oliveira said. "The areas of hotels, transport and airports are worrying. The later we leave these works, the more costly they will become."
