General Quality of Materials and Workmanship – Stone Standards

1.1	Stone is a natural building material and, therefore, variations in texture, colour, consistency and molecular structure occur. However as natural stone varies, it is recommended for the client to request viewing of the particular stone to be used.
1.2	Spotting/Colour The presence of impurities, flairs, pit marks shall be deemed as being part of the natural stone. Colour variations may occur with particular types of stone that show a lot of texture and patterns. This is to be viewed as a feature of the stone.
1.3	Workmanship Structurally unsafe stone members shall not be processed and installed in any structure or building. Processing, handling and installation of natural stone shall be carried out in a professional tradesman-like manner. Allowances for loads and conditions shall be made in the design stage – eliminating replacement due to failure of a stone member. On bench tops – cabinets and support structures are to allow for sufficient strength to absorb design loads. Climatic conditions and light can alter a surface finish and change a colour of a particular stone. This is not a result of poor workmanship.
1.4	Samples Samples are not absolute guarantee as to colour, texture, and possible impurities and are indicative only of the stone type to be used.
1.5	Generic Terms Marble, Granite, Sandstone, Limestone etc. are to be viewed as generic terms and their use characterises a particular family of rocks.
