Brazil's lawmakers have approved changes that could reduce the amount of bureaucracy stalling construction work for the 2014 World Cup and 2016 Olympics.

The lower house of Congress voted Wednesday on a provisional measure that facilitates bidding processes for work related to both events. The measure also includes more flexible rules for work ahead of the 2013 Confederations Cup.

The government says the new rules are key to expedite infrastructure projects, while critics say the measure is flawed because it doesn't require officials to publicly disclose details on the bid process and could lead to misuse of public money.

Supporters says changes are needed the work in time for the World Cup and the Olympics. The changes reduce the time to conclude the bidding processes, eliminating some stages and need for approval.
