In the context of commercial construction projects in Australia, a "crossover" typically refers to a vehicular access point that connects a property to the public road network. This includes the section of the driveway that crosses over the public footpath and any verge area to reach the roadway.  

In the context of commercial construction projects in Australia, "cupping" typically refers to a type of wood deformation where the edges of a wooden board or panel curl up or down, creating a concave or convex shape. This phenomenon can occur due to moisture imbalances, improper drying, or environmental conditions.

In the context of commercial construction projects in Australia, curing of concrete refers to the process of controlling the loss of moisture from concrete after it has been finished . This process is crucial to ensure that the concrete achieves its desired strength, durability, and quality.

In the context of commercial construction projects in Australia, a Development Application (DA) is a formal submission to the local consent authority (Council) seeking permission to carry out a new development . The DA is an application for the Council to consider a proposal for development, which includes the submission of an application form and accompanying documentation .

In the context of commercial construction projects in Australia, a "dado" refers to the lower part of a wall, typically extending from the floor to about waist height, which is often treated differently from the upper section of the wall. This treatment can involve different materials, colors, or textures, and is often used for both aesthetic and practical purposes, such as protecting the wall from damage in high-traffic areas.

Impermeable barrier just above ground level at the base of the wall to prevent rising damp. Modern damp-proof courses are generally made from 0.5 millimetre thick, black, polyethylene sheeting. One of the oldest types of damp-proof courses is made up of tar and sand. Another type of impermeable barrier that was traditionally used was glazed hard-burnt ceramic, similar in size and shape to bricks.

In the context of commercial construction projects in Australia, a "datum" refers to a reference point or level used as a basis for measuring elevations and depths on a construction site. This reference point is crucial for ensuring that all elements of the construction project are accurately aligned and constructed according to the design specifications. The datum is typically established relative to a known benchmark, such as the Australian Height Datum (AHD), which is a standardized reference level for elevations across Australia.

In the context of commercial construction projects in Australia, the term "dead load" refers to the permanent and unchanging weight of the building's structural components, such as walls, floors, roofs, and any other fixed elements. This includes the weight of the materials used in the construction, such as concrete, steel, and masonry, as well as any fixtures or equipment that are permanently installed in the building.

A diagonal brace in the context of commercial construction projects in Australia is a structural element used to provide lateral stability to a building or structure. It is typically installed at an angle, connecting different parts of the structure, such as beams and columns, to resist lateral forces like wind or seismic loads. This helps in preventing deformation and maintaining the structural integrity of the building.

In the context of commercial construction projects in Australia, a dimension refers to a measurable extent or size of a physical attribute, such as length, width, height, or depth, of a building or structure . Dimensions are crucial in construction projects as they provide a clear understanding of the physical characteristics of a building or structure, enabling accurate planning, design, and execution.

In the context of commercial construction projects in Australia, a distributed load refers to a type of load that is evenly spread over a surface area of a building or structure . This type of load is typically measured in units of pressure, such as kilopascals (kPa).

In the context of commercial construction projects in Australia, a "door" refers to a movable barrier used to cover an opening in a wall or partition, which allows access, egress, and security between different spaces within a building or between the interior and exterior.

In commercial construction projects in Australia, a door frame refers to the structural element that surrounds and supports a door. It is an essential component that ensures the door operates correctly and provides security, stability, and aesthetic appeal.

In the context of commercial construction projects in Australia, "door furniture" refers to the various hardware components and accessories that are installed on doors to ensure their functionality, security, and aesthetic appeal.

In commercial construction projects in Australia, the term "door head" refers to the uppermost horizontal component of a door frame. It is the structural element that spans the top of the door opening and supports the weight above the door. The door head is an essential part of the door assembly, providing stability and ensuring that the door functions correctly.
