Qatar World Cup 2022 organisers said on Tuesday they will allow international trade union inspections of stadium sites from next year.
Qatar's Supreme Committee for Delivery and Legacy announced an agreement with the global Building and Wood Workers' International (BWI) group for joint inspections of construction and accommodation sites.
"Signing this partnership with BWI is a major step for the Supreme Committee which demonstrates our commitment to the health and safety of our workers," said the committee's head, Hassan al-Thawadi, in a statement.
The inspections will begin in January 2017, said the statement.
The BWI represents more than 300 trade unions representing some 12mn members globally, according to its website.
Ambet Yuson, BWI's general secretary, said the agreement was an important step to "ensure workers' safety on projects directly related to the 2022 FIFA World Cup".
The union and the supreme committee will also form a joint working group that will report on the inspections.
These reports will be "independent" and released to the public, added the statement.
The announcement comes as Qatar prepares to dramatically increase the number of labourers working on World Cup projects from around 10,000 to more than 30,000 over the next year.
Qatar is in the process of introducing several labour reforms.
Last year it brought in the Wage Protection System, which ensures workers receive their salary on time.
In October Doha announced it was establishing a panel, with a judge as its head, to oversee labour disputes.
