Class 9a Building

A health care building, such as a hospital.

Class 9b Building

An assembly building, such as a school, theatre, or church.

Class 10 Buildings

Non-habitable structures divided into Class 10a (shed, garage, carport), Class 10b (pool, fence, retaining wall), and Class 10c (private bushfire shelter).

Preliminaries

The fees, activities, general plant, equipment, and labour undertaken by a head contractor during construction, refurbishment, or demolition that are not permanent physical parts of the construction.

Demolition

The dismantling, destroying, or wrecking of any building or structure (or part thereof) carried out in a pre-planned or controlled method.

Civil Works

The design, construction, and maintenance of the physical and naturally built environment that involves changing the lay of the land, including roads, bridges, dams, and railways.

Cut and Fill

The process of flattening land by excavating soil (cut) or depositing soil (fill).

Sump Pump

A dewatering system featuring a lower water reservoir or trench where water collects and is pumped away before overflowing.

Wellpoint

A dewatering system placed around shallow excavation trenches (such as pipeline trenches) to lower groundwater levels.

Substructure

The structural footing system of a building extending up to the damp proof membrane, functioning to transfer building loads to the ground and isolate the building horizontally from the ground.

Superstructure

The structural portion of a building erected on top of the foundational base or lower support.

Portal Frame Building

A stiff, rectangular structural frame made of columns and pitched rafters designed to create wide, open internal spaces free of columns.

Concrete

A structural material made from a mixture of water, cement, and aggregates (fine sand and coarse rocks), often laid over crushed stone and a vapour barrier.

Reinforced Concrete

Concrete combined with embedded steel bars or rebar to resist tensile forces and minimize cracking, compensating for concrete's low tensile strength.

Tilt-Up Panel

A site-poured (in-situ) concrete wall panel cast flat on a slab over a bond breaker, cured, and lifted into vertical position by a crane onto strip footings.

Precast Concrete

Concrete components cast and cured under controlled conditions in an off-site factory before being transported to the construction site.

Bond Breaker

A chemical or physical barrier applied over the base slab to prevent a poured tilt-up panel from adhering to the underlying concrete.

Cladding

A non-load bearing exterior layer attached to a structure for thermal insulation, weather resistance, fire safety, and aesthetic finish.

Dado Wall

A lower, reinforced wall panel made of precast or tilt-up concrete extending from the floor to a set height, typically topped by lightweight metal sheet cladding.

Ductile Failure

A gradual failure mode where a material bends and deforms significantly before breaking, providing advance warning for evacuation.

Brittle Failure

A rapid, catastrophic failure mode where a material snaps or shatters suddenly without prior plastic deformation.

Concrete Cover

The distance between the exterior concrete surface and the outermost steel reinforcement, shielding reinforcement from fire, corrosion, and environmental damage.

Tensioned Concrete

Concrete containing steel tendons that are tensioned before or after pouring to impart pre-applied compressive stresses, counteracting tensile forces under load.

GP (General Purpose) Cement

A fast-setting cement that cures within $30$ to $60\,\text{minutes}$ and develops high early strength, commonly used for slabs, driveways, footpaths, and precast work.

GB (General Blend) Cement

A blended cement that sets more slowly and develops early strength slower than GP, achieving equal or superior long-term strength; used for mortar and paving.

Concrete Slump Test

A quality control test that measures the consistency, workability, and fluidity of fresh concrete prior to pouring.

Concrete Core Test

A destructive testing method evaluating the actual compressive and structural strength of hardened concrete extracted directly from an existing structure.

Mild Steel

Low-carbon steel containing $0.15\%$ to $0.2\%$ carbon, chosen for construction due to its ductility and ability to bend under stress without snapping.

High Carbon Steel

Hard, strong steel containing $0.6\%$ to $1\%$ carbon that is brittle and prone to snapping, making it suitable for blades and tools rather than structural framing.

Butt Weld

A full-penetration weld connecting two aligned metal edges along a seam, fusing the entire face of one piece to the other through the full thickness.

Fillet Weld

A common weld typically formed at a 'T' or 'L' intersection that joins overlapping or perpendicular surfaces without penetrating completely through the metal.

Saddle-Jib (Hammerhead) Crane

A tower crane featuring a fixed horizontal jib along which a trolley moves back and forth, rotating around the tower via a slewing mechanism.

Luffing Crane

A crane with an articulated jib that raises and lowers via an electric motor and gearbox to position loads closer to or further from the tower.

Curtain Wall

A lightweight, non-structural exterior building envelope composed of anchors, mullions (vertical rails), transoms (horizontal rails), spandrel panels, and vision glass.

Concrete Core

The central vertical structural element of a multistory building that provides stability and supports suspended floors from which curtain walls hang.

Jump Form

A self-climbing formwork system that climbs vertically via hydraulic jacks as successive concrete pours of the core wall are completed.

Fit-out

The process of completing interior construction to make a building suitable for occupation, including partition walls, ceilings, flooring, and joinery.

Partition Wall

A non-load bearing interior dividing wall constructed from steel studs and plasterboard, designed to be lightweight, fire-rated, and sound-insulating.

Grinning

A plaster or render defect characterized by a shadow or faint outline visible on the wall, caused by uneven moisture absorption or inadequate render thickness.

Crazing

A render defect characterized by a fine network of surface hairline cracks, typically occurring when the render dries too fast in hot or windy conditions.

Active Fire Protection

Fire safety systems that require detection and automated or manual mechanical operation to suppress a fire (e.g., sprinklers, alarms, fire extinguishers).

Passive Fire Protection

Built-in stationary structural design elements that contain or restrict the spread of heat, flame, and smoke without activation (e.g., fire-rated walls, dampers, and compartmentation).
