Planners in City Hall have sought further information on plans for a new Helipad at Cork University Hospital.
The planning application for the new helipad was lodged with City Hall in December, shows the new helipad will be constructed on the staff car park at the northeast corner of the hospital grounds.
The planning notice confirmed the development would include a new two-storey staff car park, to replace the 164 spaces lost as a result of the helipad construction.
The hospital has described the development as a critical piece of infrastructure.
The plans have attracted objections from a number of residents in nearby estates concerned about safety and noise saying the helipad would injure the use and enjoyment of their homes and surrounding areas.
Planners in City Hall have now asked the HSE to supply further information on the development.
They have been asked to confirm that the helipad will be solely used for the transfer of critically injured patients and the outbound transfer of organs and if the takeoff and landings will take place on a 24-hour basis.
The HSE must also provide details of noise mitigation measures and an in-depth noise report with special consideration given to the residential homes nearby.
The HSE now has six months to reply to the request.
