In the context of commercial construction in Australia, camber refers to the upward curvature of a structural element, such as a beam or a slab, to counteract the expected deflection under load. This technique is used to ensure that the structure remains level and plumb, and to prevent excessive deflection or sagging.

In the context of commercial construction in Australia, a bulkhead refers to a vertical or sloping structure, typically made of wood, steel, or other materials, used to provide support and separation between different areas of a building . Bulkheads are often used to contain fittings, such as range hoods, or to create decorative features.

In Australia, a building line refers to the boundary or line that defines the minimum distance between a building and a street, road, or other public space. This line is also known as the building setback or building alignment.

Building codes in commercial construction in Australia are a set of regulations and standards designed to ensure the safety, health, and sustainability of buildings. These codes are primarily governed by the National Construction Code (NCC), which includes the Building Code of Australia (BCA). The NCC is a performance-based code that sets the minimum requirements for the design, construction, and performance of buildings throughout Australia.

Building by-laws in Australia refer to the set of rules and regulations that govern the design, construction, and maintenance of buildings, including commercial constructions. These by-laws are primarily outlined in the Building Code of Australia (BCA) and relevant Australian Standards .

Common `Blocks of material moulded from clay or cement used for building or paving purposes. Usually bricks burnt in continuous kilns; used in general work.

Brick veneer is a type of building construction where a thin layer of bricks is applied to the exterior surface of a building . In Australia, brick veneer is a common construction method used in both residential and commercial buildings.

Brick construction in commercial construction in Australia refers to the use of bricks as a primary building material for structural and non-structural applications. This includes brick veneer, solid brick, and cavity brick construction methods

In the context of commercial construction in Australia, bracing refers to the structural elements or systems used to resist lateral loads, such as wind and seismic forces, and provide stability to a building . Bracing is an essential component of a building's structural system, ensuring that the structure can transfer loads to the ground with an adequate safety margin to prevent collapse.

In Australia, a box gutter is defined as "a graded channel, usually rectangular in shape, used to collect and convey rainwater from a roof to a downpipe or a drainage system" . Box gutters are an essential part of the roof drainage system in commercial construction, allowing for the efficient collection and disposal of rainwater.

Three rods with tee heads used to sight a straight line between two given points. Boning rods are a type of surveying tool used in commercial construction in Australia to set out levels on paving, drainage, and hard landscaping projects . They consist of a set of rods with graduated markings, used to measure and establish the correct levels and gradients on a construction site.
