Mona Vale Hospital Redevelopment

The Mona Vale Hospital Reconfiguration project involved the demolition of eight buildings on the hospital site, including the main hospital building, staff amenities, and administration blocks. The project was part of NSW Health Infrastructure's broader redevelopment plan to support the transitioning role of Mona Vale Hospital.

The tallest structure, Building 1, was approximately 30 metres high and comprised a seven-storey main hospital building with a basement. The structural composition varied across the site, with some buildings constructed using reinforced concrete slabs, beams, and columns, while others featured steel-framed structures encased in concrete. The total weight of debris from these demolitions was substantial, requiring careful planning and execution.

The scope of works included the removal of hazardous materials, disconnection of services, structural demolition, and subsequent civil and landscaping works. Special attention was given to maintaining safety, minimising disruption to ongoing hospital operations, and ensuring environmental compliance throughout the process.

Hazardous Materials Removal: Removal of asbestos and other hazardous materials was conducted prior to the structural demolition. Air monitoring and clearance certificates were completed and obtained by a licenced Occupational Hygienist. This phase involved the careful removal of materials to prevent contamination and manage approximately several tonnes of hazardous waste.

Demolition: Demolition of the eight building was carried out, starting with stripping the buildings to their shells. The demolition process involved both small and large excavators, using a top-down approach to ensure controlled and safe deconstruction of the structures. The buildings were comprised of primarily reinforced concrete and steel, which was carefully managed to control the debris weight and ensure efficient recycling.

Service Disconnection and Site Preparation: All utilities, including water, power, and gas, were disconnected and capped to prevent any hazards during demolition. Temporary services were installed for dust suppression and site amenities. The site was secured with fencing and environmental controls to protect hospital staff and the public. The preparation also included reinforcing critical areas to manage the load from heavy machinery used during the demolition process.
