Assembly Buildings

Auditorium, Aquatic and Stadium projects pose interesting challenges for fire safety engineering given the large population numbers within these areas. Coupled with the requirement to satisfy life safety objectives, there is generally a strong underlying driver in providing flexibility within the design so the end users can use the area for different functions. Affinity has produced numerous schemes that involve modelling techniques within our analysis methods to demonstrate the safe evacuation of large population numbers.


The 2000-seat theatre was designed by COX Architecture and was awarded multiple design awards. It required bespoke fire engineering analyses to evaluate safe occupant evacuation, structural fire ratings and unique fire detection services. The development included a large auditorium with an associated fly tower, flexible seating arrangements and a large atrium function space. Our experienced staff provided successful performance-based solutions to meet project aesthetic and operational needs, while maintaining acceptable levels of occupant and firefighter life safety.

Affinity has been engaged by Mantric Architecture to develop a Performance solution for the Mullum Mullum Reserve Highball Stadium. The building is a Class 9b building with five indoor sports courts, seating for up to 500 spectators, amenities and a café. The challenges for this project include evaluating safe occupant evacuation, structural fire ratings and unique fire detection services.

The redevelopment included the refurbishment and expansion of the existing building. A portion of the existing building remained. This building is a Class 5 and Class 9b building with three indoor swimming/leisure pools, gymnasium, café, offices, childcare facility and ancillary areas. The redevelopment of this project has been finalised in 2021.
