Blasting next to a heritage bulding in Fortitude Valley, Brisbane City

So I am currently assessing how to build a 4 m basement car park in a swamp with a CBR of 1.5.  I could go into the details of that but, while researching my thesis I came across these videos of blasting in two of my case studies Fortitude Valley and 300 George Street which are far more interesting.  How do you get away with blasting very hard rock in the middle of a city?  With a lot of careful planning. Note the mattresses to prevent fly rock and the drilling before hand in the 300G video not just for placing the explosives but to localise the effect of the shockwave
