In designing the new redevelopment for Lismore Base Hospital, particular attention needed to be given to the area’s high storm risk. TTW’s design was required to address post disaster loading in a high cyclone area over multiple project phases. In some instances, wind loads were over 7kPa in magnitude – leading to challenges with lateral stability and cladding design.
TTW engineers produced sensible economic design solutions to minimise impacts of wind, and worked closely with subcontractors to ensure appropriate material selections. All of the floors in the 10 storey new building were modelled for a high level of vibration response to ensure that sensitive equipment could function properly. The central stability core utilises AFS due to limitations in local formwork trade in the region – this is possibly now the largest building in NSW to use AFS for its stability core.
Delivered in stages, the Lismore Base Hospital redevelopment is a major investment in the upgrade of health care services for the northern NSW region. TTW has worked with a large number of stakeholders to ensure the successful delivery of this important project.
