The low rise sports complex building is classified as a class 9b building because it is an assembly building of a public nature (Australian Building Codes Board, 2015). This is a building that is open to the public for various sporting activities thus its purpose fits the class 9b classification based on Building Code of Australia (BCA) guidelines. The type of construction for this building is timber framed construction. This is because timber framed construction is most suitable for low rise structures and has numerous benefits. Some benefits of timber construction include: it is flexible and provides unlimited design options, has high aesthetic value, provides ultra-modern look, provides superior flexibility in terms of future renovations and additions, it is strong and durable, it is easy to maintain, reduces construction period by enabling prefabrication, has great thermal and acoustic performance, it is more energy efficient (Frankel, 2016), has numerous environmental benefits, and is a renewable resource hence sustainable (Kremer & Symmons, 2015). Therefore timber frame construction suits the purpose of the building and will also provide economic and environmental benefits throughout the building’s lifecycle.
The BCA criteria that has been used to classify the building include: the purpose or intended use for which the building has been designed for, the nature of the building, the arrangement of the building and number of storeys or height of the building. Other BCA criteria used in building classification are floor area calculation and volume calculation. The intended use of the building is the main BCA criteria for building classification. The intended use determines the risk level of the building, which is essential in building classification (Building Codes Queensland, 2012). The sports complex building in this case is a low rise and it is intended to be open to the public i.e. people who are interested in participating in different sporting activities. Therefore the intended use of the building suits BCA criteria for class 9b buildings.
Other possible uses
The low rise sports complex building can also be used as a healthcare building, trade workshop, early childhood centre, shop for retail selling of goods or direct supply of services to the public (such as eating room, café, bar, restaurant, dining room, laundry shop, barber’s or hairdresser’s shop or showroom), and office building used for commercial or professional purposes. This will change classification of the building from class 9b to multiple classification depending on the intended use. This basically means that every part of the building has to be classified separately because of the different purposes. To make is suitable for these other uses, some renovations or improvements will be necessary.
