Well in construction industry, because it's usually such a large scale project theres heaps of sub branches. The two big ones are Design or Management. Design are the ones that obviously draw the plans, write up all the specifications for the road (quality, depth etc) its all very interesting. I more dealt with the management, so there the ones that make sure that all the concrete matches specified density, thickness, structural analysis. Also alot to do with drainage, and making a sustainable environment etc. Then some specify in concrete, others in geotechnical ( soil) etc etc... It would be very very interesting in my opinion. Basically large scale means a fair bit of travelling but very large salary ( prob $200k+/year)+car+mobile+rent paid for ( well thats what they get at Abigroup anyway), but the only down side is that its pretty big hours prob like 50-60hrs a week, over 5 days.
