QUT’s Q Block at the Kevlin Grove campus, (KGQ) houses critical laboratory research facilities that require Process Containment Level 2 and 3 (PC2 & PC3) certification under the Office of the Gene Technology Regulator (OGTR). Constructed in 2006, Q Block is an 8-storey building with the following layout:
•Levels 1 & 2: Car parks
•Level 3: Back of house equipment, main switchboard, chillers, and additional car parks
•Levels 4 to 7: Offices and laboratories
•Level 8: Roof and plant equipment, including the primary 100% outside air handling units (AHUs) thatsupply ventilation to all laboratories (Wet Labs) and offices (Dry Labs)
The AHUs, located on Level 8, are large built-up units containing filters, heat wheels, coils, and supply and return fans. The Wet Lab AHU (Laboratory) provides an airflow of 7,000 L/s, while the Dry Lab AHU (Office) provides 12,000 L/s. The AHUs operate in a duty-only configuration, supplying and exhausting air without the ability to shut down for servicing. This configuration limits the ability to conduct maintenance without disrupting research activities, particularly OGTR laboratory operations. Additionally, the electrical configuration of the existing plant lacks shutdown capabilities, further complicating maintenance and impacting reliability.
Q Block is designed as a fire-engineered solution, with the Dry Lab AHU providing essential services during fire mode. However, the plant has now reached the end of its operational life, exhibiting performance and reliability issues. A like-for-like replacement of the existing system is not feasible due to the design limitations and the potential for prolonged downtime. Therefore, a staged approach is necessary to upgrade the system while maintaining operation of the existing AHUs.
The key objectives for the mechanical plant upgrade project are as follows:
•Correct Latent Engineering Issues: Resolve existing latent engineering issues with the primary plant,ensuring improved functionality and performance.
•Replace Primary AHUs: Replace the two primary AHUs with revised, energy-efficient models designed toreduce space humidity in a more efficient manner, while minimizing interruption to building operations.
•Staging and System Changeovers: Construct new plant platforms and staging areas to facilitate systemchangeovers and ensure minimal disruption during the transition phases.
•Enhanced Resilience: Design a more resilient system, both mechanically and electrically, by incorporatingN+1 redundancy for critical equipment and ensuring diverse electrical supply paths to support major plantitems.
•Future-Proofing: Design pathways to allow for future service maintenance and component removal. Include considerations for future fit-out requirements to streamline potential future upgrades.
