Almost all construction projects use machinery.
It could be a 1,000 tonne, 7 meter wide remote-controlled boring machine needed to tunnel out an underground railway, or a crane that sits 1,000 feet in the air and lifts glass panels to the top of a skyscraper. Or it could be an excavator, earth moving truck or pile-driver and paving machine. Whatever type and size of machine it is it needs an operator, a supervisor and a mechanic to fix it should it go wrong. People are also needed to make sure that vehicles and machines, both loaded and unloaded, are in the right place at the right time and ready for use. This area of work is called Logisitics.
Senior managers are responsible for leading teams of people working on all kinds of construction projects. As the boss, he or she comes up with strategies for getting jobs done efficiently, then makes sure people follow them.
