With the rapid growth of population, old buildings must be demolished quickly and replaced with new architectures to fit this problem. However, there are plethora of blasting cases ended up with huge damage to the neighborhood and cause injuries or death because of lack of details to the building and the mistakes of explosive installation. This project combines BIM (Building Information System) with virtual reality to aid the whole blasting process from site analysis to training and finally the installation of explosives. The constant training can make engineers more cooperative and familiar to every detail of building and explosives.
