Which aspects of subway construction will the speaker talk about in this lecture?
(geological conditions): you need to be absolutely sure that the ground, and more to the point, what lies beneath the ground can support underground transport
(employing professionals): engineers have to be really experienced, really knowledgeable ". And those key issues ore what I want to focus on today,
Last week we looked at urban regeneration and some of the consequences of this, one of which was the relocation of people from urban to suburban areas, to, er, to largely allow them a better standard of living - because housing is cheaper in the suburbs, so they have more disposable income. But they have to commute, and commuters need rapid transport to get them from A to B. So subway construction is, well, it's booming in some parts of the world - it's clearly being seen as the 'answer' to the type of migration that I've just mentioned. It often gets huge public support because - well - if a subway's going to help you have a better lifestyle. then what's there to argue about. Well, quite a lot actually. For a start, in order to go ahead with a major project of this kind you need to be absolutely sure that the ground, and more to the point, what lies beneath the ground can support underground transport. And to address questions like that, engineers have to be really experienced, really knowledgeable about the local area, water levels, land formation and so on. And those key issues are what I want to focus on today. Passengers don't think about construction, they trust other, better qualified people to do it for them. and governments have to choose these people very carefully.
