MATHER-- Construction continued at Mather Field Thursday after an accident sent two people to the hospital.
"They arrived to find large metal beams had collapsed down at the construction site," Sac Metro Fire Assistant Chief Maurice Johnson said.
Assistant Chief Johnson said the large metal beams fell at the site where aircraft hangars are being built.
"The way the beams fell they kind of self stabilized themselves with the ground and the beams that are still standing," said Assistant Chief Johnson.
Sac County Airports confirms the accident happened at the EVA Flight Training Academy, a tenant of Mather Field.
Johnson said the workers' injuries are "moderate."
Cal OSHA says the workers were hurt after losing control of an iron beam they were trying to connect to another.
"It's part of the business," Jim Meurer is a specialty contractor working on the building adjacent to the hangars.
He came to check things out after hearing what happened.
"Its an inherently dangerous component of construction but apparently there was a shift in the building frame and they started sheering bolts and they lost the structure," Meurer said.
Meurer says no matter how safe you are, accidents are part of life in construction.
Luckily, these workers were not severely hurt.
"The immediate concern is for the patients, to make sure the scene's secure. The scene is secure and the patients have been taken care of and the rest falls with the construction company," said Assistant Chief Johnson.
Metro Fire says the construction company is Ascent Builders.
