Electricians were originally people who demonstrated or studied the principles of electricity, often electrostatic generators of one form or another. Without electricians, there would be no lights, telephones, computers, or televisions plugged into our walls.

Surveyors are expert in the science of positioning and measurement – this can involve applications from creating an accurate topographic map, monitoring movement on or below the earth’s surface, or ensuring that the foundations for a new high-rise building are in the correct location. Some surveyors choose to specialize in the field of hydrographic surveying which might involve activities such as precise oil rig positioning, accurate bathymetric mapping and charting of harbours, and marine navigation. Surveyors are also experts in land development set outs and design work. This might involve taking an area of land and laying out the roads and infrastructure such as water, sewage, and power supply that will support a new community. This process includes preparing planning consents, undertaking the engineering design for the roads, storm water and sewerage systems that will service the community, and then supervising its construction.
