FOSTER CITY, Calif. --An investigation is underway into what caused the partial collapse of a building in Foster City Monday morning, sending four construction workers to the hospital.
Two of the workers at the construction site suffered moderate injuries while two others had minor injuries and have since been released from the hospital, according to Ron Meade, president of R.C. Pacific Construction, Inc., the Roseville-based contractor for the building project.
"Hopefully they're going to be fine," Meade said of the workers.
Fire crews were dispatched to the partial building collapse in the 1100 block of Triton Drive around 10:30 a.m., authorities said.
California Division of Occupational Health and Safety spokesman Peter Melton said part of the under-construction wooden building gave way after a support structure called a truss collapsed.
Melton said the building will be a Carl's Jr. restaurant, which Meade declined to confirm.
Cal/OSHA investigators were on scene this afternoon to look into what caused the collapse. Meade said R.C. Pacific Construction is conducting its own investigation into what happened.
