Berkeley contractors censured
Five contractors who worked on the Berkeley building in California where six students died face losing their state licences.
The Contractors State Licence Board found that "poor workmanship" in the waterproofing of the balcony resulted in water damage that caused it to rot and eventually collapse.
"They didn't do the work (on the balcony) to trade standards," said Dave Fogt, the board's chief of enforcement.
The collapse was caused "definitely by water incursion that caused dry rot".
Irish students Olivia Burke, Eoghan Culligan, Lorcan Miller, Niccolai (Nick) Schuster and Eimear Walsh, all 21 years old, and Ms Burke's cousin Ashley Donohoe (22), from California, were killed in the tragedy in June 2015. Seven others were seriously hurt.
Last week, state prosecutors confirmed that nobody would face criminal charges over the horror collapse.
The companies cited in this latest move include the project's main contractor, Segue Construction of Pleasanton, said Rick Lopes, a spokesman for the licence board. The others are Etter & Sons Construction in Dana Point; R Brothers Waterproofing in San Jose; North State Plastering in Fairfield; and The Energy Store of California in Sacramento.
All declined to comment.
