Eastwood, South Australia, Australia
Eastwood Private Hospital is a purpose-built 48-bed, six-storey facility in Eastwood, South Australia, delivering a broad clinical scope that includes radiology, pathology and allied health services alongside orthopaedics, plastic surgery and endoscopy. The hospital is designed to admit more than 7,000 patients a year, directly reducing waiting lists in the Adelaide metropolitan area. In addition to the clinical floors, the development includes a multi-level car park, a cafe and retail areas, making it a mixed-use building of considerable scale and technical complexity.
Given the breadth of clinical services and the tight performance requirements that apply to hospital mechanical systems, including the ventilation standards that govern infection control, air quality and patient comfort, the project demanded a mechanical engineering approach that could balance design rigour, code compliance and practical buildability.
Dewick & Associates was engaged by Watson Fitzgerald & Associates as the Mechanical Services Contractor to provide Design and Construct Mechanical Engineering Services for the project.
Our scope included detailed heat load analysis using thermal dynamic simulation software, and a ventilation assessment covering both outside air supply and exhaust systems to ensure full compliance with AS 1668.

Watson Fitzgerald & Associates is a South Australian mechanical and building services engineering practice with extensive experience in the healthcare sector. As Mechanical Services Contractor for Eastwood Private Hospital, Watson Fitzgerald & Associates was responsible for the full mechanical engineering scope of the hospital, a project type where the engineering requirements are shaped by clinical infection control standards, patient comfort expectations and the complex interplay between different service zones within the same building.
Dewick & Associates was engaged to bring specialist capacity to the heat load analysis and AS 1668 ventilation assessment, ensuring the mechanical engineering design was both code-compliant and fit for purpose across every clinical and ancillary space.
Delivering mechanical services documentation for a multi-storey private hospital requires a highly coordinated approach due to the complexity of clinical environments and the strict compliance standards governing healthcare facilities. Spaces including operating theatres, endoscopy suites, pathology areas and patient rooms each carry unique ventilation, pressurisation and infection control requirements under AS 1668, demanding precise coordination between design intent, installed systems and final operational documentation.
The six-storey hospital layout, combined with integrated retail and car parking zones, added further complexity to the thermal modelling, ventilation zoning and system integration across the facility. Capturing this accurately within the project documentation required detailed technical verification to ensure all operational, maintenance and compliance requirements were clearly documented for long-term facility management and clinical performance.
Dewick & Associates delivered a detailed Mechanical Engineering Services tailored to the operational demands of a complex healthcare environment. Using thermal dynamic simulation software, our team modelled the hospital’s thermal performance across a wide range of operating conditions, providing an accurate and reliable basis for mechanical plant sizing and system design.
Our engineers undertook a comprehensive ventilation analysis across all clinical and non-clinical zones, carefully assessing outside air supply, exhaust systems and pressurisation requirements in line with AS 1668 and healthcare infection control standards. By applying detailed simulation modelling rather than simplified calculation methods, we helped Watson Fitzgerald & Associates minimise design risk, optimise plant selection and achieve a practical, fully compliant solution suitable for construction and long-term hospital operation.
The project delivered a fully compliant mechanical engineering design for Eastwood Private Hospital, supported by detailed thermal dynamic simulation and comprehensive AS 1668 ventilation assessments. The final design ensured each clinical and non-clinical space was provided with appropriately sized and carefully coordinated mechanical systems tailored to the operational requirements of a modern healthcare facility.
For Watson Fitzgerald & Associates, the outcome provided a reliable and technically robust engineering foundation for the mechanical scope, supporting the successful delivery of a hospital that now services more than 7,000 patients annually.
With extensive experience across healthcare and technically complex projects, Dewick & Associates provided the specialist expertise required to balance compliance, operational efficiency and real-world constructability within a critical clinical environment.
