though it's the first thing that people think of when they think demolition, Blasting is reserved as a last resort for most projects. if it is in any way feasible to do mechanically, it will be. blasting accounts for less than 1% of all demolition, especially since once the blasting is done you still need equipment to clean up the mess. it is a huge liability, and SOOOO much red tape! We're shooting a stack on saturday, which has been re-scheduled 4 times because of nothing more than dust control issues.
