Westmead Private Hospital is owned and operated by global hospital group, Ramsay Health Care.  The new $25m luxury maternity facility offers unrivaled comfort to patients and includes 31 extra maternity rooms, as well as 11 new surgical rooms and one extra birth suite.  A 14 cot Special Care Nursery is equipped with the latest technology for babies who need extra care and offers greater privacy and comfort for parents.

Utilising the Early Contractor Involvement model, Erilyan appointed ACOR consultants to work in close collaboration with HPI Architects and the building team to deliver over 5,000 sqm of additional space on a narrow footprint. Having delivered structural and civil engineering services on previous upgrade works within the hospital, the ACOR team brought an intimate understanding of the site conditions and constraints. Located to the west of the existing main hospital, the extension required careful integration with the adjacent buildings, adding 2 additional floors whilst allowing the existing maternity facility to remain in operation throughout.

Onsite noise and dust were minimised thought the selection of a steel frame structure with a composite slab system, resulting in a highly efficient and lightweight design. Whilst minimising the amount of concrete pouring required, the team was able to construct a Truss that spans nearly 50m across the driveway and loading dock. This reduced the need for intrusive groundwork and ensured continual access during construction, further minimising disruption to the existing facility.

Prefabricated materials and modular bathroom pods were installed to ease constructability and improve moisture control through airtightness. Additional structural features within the interior include a feature staircase and skylight which connects the 3 levels and allows natural light to filter through each floor.

Working around the confines of the existing building envelope, the Structural and Civil engineering team assessed the capacity of the existing structures and developed solutions to ensure the smooth transfer of loads, working alongside the construction team to relocate load-bearing columns and optimise the floorplate.   The team remained involved throughout the construction phase, attending site with the contractor to coordinate with the hospital facilities teams and ensure the smooth handover at completion.
