Officials are investigating an industrial accident at the powerhouse at Muskrat Falls in Labrador.
Matthew Pike, spokesman for Astaldi Canada, says the structure supporting concrete that was being poured collapsed at about midnight.
He says seven employees were treated at the site, while another worker was sent to hospital in Happy Valley-Goose Bay for assessment of injuries that were not considered serious.
Nalcor Energy spokeswoman Karen O'Neill said in an e-mail that company officials were gathering information at the site of the hydroelectric project.
Gilbert Bennett, vice-president of the Lower Churchill Project, issued a statement saying further work by Astaldi in the area is being suspended while the investigation is under way by Occupational Health and Safety officials.
The province has spent almost $4.8-billion building the dam and powerhouse on the lower Churchill River, the largest publicly funded project in its history.
