You are right, the recent Grenfell Tower disaster raised investigation in my country too, we also found some of the buildings adopted the same cladding material as Grenfell, the government here is still conducting further investigation and discussing about reconstruction of the subject buildings.
Indeed, I think the government in UK is responsible for this disaster! The role of buildings department is to ensure the building is safe! everyone knows how harmful an unsafe building can be, just like this disaster! The government is responsible to monitor and update the regulations, as well as inspection to ensure the buildings are safe! Can't imagine Grenfell Tower doesn't even have sprinkerhead system, that is ridiculous!
I wish the UK buildings department can review their policy and regulations, as well as inspection scheme to avoid this happens again.
Hopefully they will.
