The Development Bureau criticises the Architectural Services Department for lack of oversight in relation to the Queen Mary Hospital lift scandal.
Some lawmakers suggest the relevant head of department to bear responsibility for the incident.
This as 28 lifts were found to be defective in the Development Bureau's investigative report on the matter.
The document further said the lift installation contractor and subcontractor should bear the most responsibility, while the Architectural Services Department should bear a portion of responsibility owing to their lack of oversight.
Speaking at a Legislative Council forum on the scandal, Secretary for Development Bernadette Linn admitted there were issues with the project's implementation.
