Scenario

 

You are the supervisor of a construction company about to begin work on a single-storey timber clad residence and a warehouse.

The timber clad residence will utilise typical construction techniques such as timber framing and roof trusses. The warehouse will utilise concrete panel construction and structural steel.

As the building supervisor of these projects you will need to interpret the project documentation to ensure the proposed buildings constructed according to current relevant state legislation, the BCA, Australian standards and good building practice.

There is an existing asbestos-clad shed on one of the sites and you must ensure it is demolished in accordance with legislative and planning requirements and safe work practices.

Work through parts 1 to 9, referring to the appropriate documents.

·         List the professionals or consultants you may consult to ensure a structure designed and built in these environments complies with building regulations.

·         Specify which parts of the structures that may need additional design and construction considerations.

 

**Present your specifications using the table located in Appendix 2

 

Required Resources

·         NCC Volume 2

c.    You are considering using an alternative exterior wall cladding on this project. You have been told about MasterWall polystyrene wall cladding by an architect. You have never used a polystyrene cladding system before and are unsure about this product.
