Zou told reporters from China and abroad on Tuesday that the final phase was to check the quality of every unit and make sure any problems are rectified.
Reporters were invited to the project by the media center of the 18th National Congress of the Communist Party of China.
Gao Kuiqing, a 50-year-old migrant worker from Henan province, said on Tuesday that the public rental housing policy was great because it helped low-income residents.
He started to work on the project site at the beginning of this year. Now his job is to check the quality of units with other workers.
A training room was set up on the construction site for migrant workers to receive skills training and to deal with safety issues and other regulations, said Wang Zhiming, a manager from Beijing Construction Engineering Group, which is responsible for the construction.
He said although the construction cost of public rental housing is low, it requires high standards of quality.
