Day 91: Between a rock and, er, another rock

 I don't envy Swedish builders.

To build foundations they have to drill down into endless hard rock, insert TNT into the gap and then blow apart the stone.

Then, they have to clear away all the rubble and repeat over and over again until the area is clear. This seems to me a slow and meticulous process (although, ok, they get to use TNT which might alleviate the repetitiveness somewhat)

There isn't much of this going on in London, where the ground is much softer and if we used TNT it would just cause mud and clay to splat all over the place. Fun perhaps but not productive.
