In Australian commercial construction projects, a "knot" refers to a unit of measurement used to quantify the number of timber boards or planks in a bundle. It is commonly used in the timber industry to describe the quantity of timber products being supplied or used in construction.

Kiln drying in the context of Australian commercial construction projects refers to the process of drying timber in a controlled environment using a kiln. This method involves placing sawn timber in a kiln, where temperature, humidity, and air circulation are carefully regulated to reduce the moisture content of the wood to a specific level.

In Australian commercial construction projects, "kerfing" refers to a technique used to create curves or bends in materials that are typically rigid, such as wood, metal, or plasterboard. This is achieved by making a series of cuts, known as kerfs, along the material. These cuts do not go all the way through the material but are deep enough to allow it to bend or flex. The spacing and depth of the kerfs determine the radius of the curve that can be achieved.

In Australian commercial construction projects, the term "kerb" refers to a raised edge or border that is typically constructed from concrete, stone, or other durable materials. It is used to separate different areas of a construction site, such as parking lots, driveways, and pedestrian walkways.
