I feel like solid bedrock is actually a perfect soil type for engineering. Other towns has to account for moving sandy or clay soils, diverting or pumping out their ground waters (sometimes it's even easier to actively freeze large areas of land).
- inglor_cz 6y agoPrecisely. Here in Prague, the subterranean geology is horrible. Broken rock, cavities, a lot of river deposits, unexpected (and rich) water springs. Not to mention a thick layer of shit dating from 1350 to approximately 1800 along a former ditch that separated the Old Town from the New Town and that served as a latrine for thirty generations of burghers. Building subway tunnels in such conditions is an equivalent of Olympic Games for engineers.
