How much do you actually have to know about, you know, the soil, the ground underneath?
Well you – you carry out borehole tests and you take out samples and you test the quality of the rock, and you think if you’ve got down far enough then it’s alright, because as you go down the load in spread out into the mass of the rock. You often do come across differences, I know on the first Bosphorus bridge we had – I had a lot of trouble on the pier on the Asian side there. On the face of it it was just a simple pier, just a bit of rock and not very big and build the pier, but wherever we looked and did drilling the rock wasn’t as good as it should have been. But there again in the end by going deeper and doing more tests we finally ended up with something that was good enough.
