In the context of Australian commercial construction projects, a "module" typically refers to a prefabricated section or unit of a building that is manufactured off-site and then transported to the construction site for assembly. This modular construction approach is increasingly popular due to its efficiency, cost-effectiveness, and ability to reduce construction time and waste.

Key characteristics of modules in this context include:

1. Prefabrication: Modules are constructed in a controlled factory environment, which allows for higher quality control, reduced weather-related delays, and improved safety conditions.

2. Standardization: Modules are often designed to standard dimensions and specifications, which facilitates easier transportation and assembly on-site.

3. Flexibility: Modular construction allows for a high degree of customization and flexibility in design, enabling the creation of complex structures by combining different modules.

4. Sustainability: The modular approach can be more sustainable, as it often results in less material waste and can incorporate sustainable building practices and materials.

5. Efficiency: By constructing modules off-site while site preparation and foundation work occur simultaneously, overall project timelines can be significantly reduced.

In Australian commercial construction, modular construction is used for a variety of building types, including offices, hotels, schools, and healthcare facilities, among others.
