Ahead of the resumption of work, more than 100 workers gathered early Monday for a prayer honoring the two victims.
Brazil's preparations for the World Cup and the 2016 Olympics have been plagued by delays, cost overruns and constant pressure to move faster. Officials from world football's governing body, FIFA, have publically scolded Brazilian officials over the problems, and a series of spats have occasionally flared up between the two sides.
Six of 12 World Cup stadiums were delivered for the Confederations Cup, a World Cup run-through, earlier this year, and FIFA is pressing for the six others to be delivered by the end of December.
Although Wednesday's accident did minimal damage to the Itaquerao, which officials had said was 94 percent finished before the accident, it's widely assumed the stadium will not meet that deadline.
Resumption of work on the stadium, which is also known as Arena Corinthians, came as FIFA officials began to gather in the coastal Brazilian state of Bahia ahead of Friday's World Cup draw.
