The Robert and Jeanne Szeto PET-CT Centre at Sydney Adventist Hospital is the largest purpose-built centre of its kind in New South Wales. The 450sqm fit-out includes offices, reporting rooms, reception area, patient injection/uptake rooms, and radioisotopes handling facilities. The centrepiece of the project is the new PET-CT diagnostic scanning room which with cutting-edge technology allows for more efficient and accurate diagnosis and can detect conditions that doctors were not able to identify 30-40 years ago. The Robert and Jeanne Szeto PET-CT Centre is a testament to the generosity and legacy of the Szeto family and the commitment of the surrounding community to support the Sydney Adventist Hospital. This project is small but very intense. The PET-CT itself is relatively new technology in Australia with only a handful of others in NSW. The PET-CT installation required FDC to cut trenches in the ”suspended” ground floor slab to accommodate service lines presenting challenges as the slab sitting on fill was designed originally as a suspended slab requiring detailed engineering calculations to locate the trench cuts. Radiation shielding was a major demand of the project - the dosing rooms are where the most dangerous risk of radiation is, and some of the walls include lead shielding up to 16mm thick. The PET-CT room is fully lead lined and includes a lead glass window to the control room. It is very technically demanding to ensure the contiguity of the lead shielding around doors, frames, and behind service panels. This small, but intense and technically complex interior fit-out exudes a feeling of quality. The finishes, fit and junctions throughout are first class and it is clear that the construction team had the passion to deliver a high-quality specialist unit. The brief for the PET-CT unit was complex both in terms of patient and staff flows, but also in the management of radio nuclear isotopes that are given to patients in the dosing rooms prior to the PET-CT diagnostic procedure. The design and quality of the unit successfully shields patients from the high technology of the PET-CT process creating a calm and ordered series of spaces and a very happy client.
