Building Sites (My First Discoveries)

Inhaltsangabe

Watch an abandoned building being demolished and a new one rise up in its place. Observe concrete cutters, bulldozers, excavators, concrete mixers, cranes, tunnel borers and steam rollers at work on a building site, at a boatyard, building an underground tunnel, a motorway and a dam. Learn about all the different people involved in each stage of construction: architects, masons, carpenters, plumbers, electricians and many others.
