I picked up some news about the Empire demolition at the open house for 1444 Alberni.
Sadly, for those select few who enjoy such things (in short, all of us), there will be no implosion of this building. Apparently with the dangers of silica exposure, WorkSafeBC has all but banned the practice.
Instead, the demolition will use a combination of Mastclimbers and Brokk Demolition machines. Apparently the result will be a much quieter and faster demolition than if done by traditional means (exempting the obvious implosion method). The process should be completed by December 2018.

There is an even more impressive technology that is being brought to Canada, but not in time for this project. That method, using the jacks, allows for a tower to be demolished floor by floor from the bottom up!
