Riggers assemble and install rigging gear such as cables, ropes, pulleys and winches to lift, lower, move or position machinery, structural steel and other heavy objects.

Roofers cover houses and other structures with roof tiles, slates, shingles or steel sheeting to form waterproof and durable surfaces.

Sampler testers assist engineers, technical officers and other laboratory staff by collecting and preparing samples, carrying out experiments, making measurements with scientific equipment, recording results and presenting results for critical analysis. Sampler/Testers carry out basic sampling and testing, record and present results and clean, maintain and set up equipment for use in experiments. They play an important role in manufacturing quality control.

Scaffolders erect and dismantle scaffolding to provide work platforms on building or industrial sites, or for temporary structures such as stages, seating and catwalks.

Solid plasterers apply decorative and protective coverings of plaster, cement or similar materials to the interiors and exteriors of buildings.

Steel fixers position and secure steel bars or steel mesh to reinforce concrete structures.

Survey assistants help surveyors measure and analyse the position, shape and elevation of the Earth's natural features (such as hills, valleys and waterways) and to determine land boundaries for housing estates, building sites, reservoirs, roads and drainage systems.

Surveyors measure, analyse and report land-related information for the planning and regulation of land, sea and the environment. Surveyors may work in related fields such as photogrammetry, geographic information systems (GIS) or remote sensing, and as project managers. After spending some years in the field, they often progress to management roles.

Swimming pool and spa builders install and construct in-ground and above-ground swimming pools and spas in both residential and commercial locations.

Swimming pool and spa technicians chemically treat pools and spas. They may also install, maintain and service pumps, filters, heaters and other related equipment.

Wall and floor tilers lay ceramic, clay, slate, marble, glass and other types of tiles on external and internal walls and floors to provide protective and decorative finishes.

Urban and regional planners develop policies and plans for the use of land and resources. They advise on the economic, environmental, social and cultural needs of particular localities or regions as they relate to the built environment and the community. They also work on large-scale projects such as new suburbs, towns, industrial areas, commercial and retail developments, urban renewal projects and transportation links.

Wall and ceiling liners make, apply and fix the internal and external linings of commercial and domestic buildings. These linings may include office partitions, non-structural walls and ceilings.
