This is a vey good question.
Inspection is missing in our country to large extent.
In the past, In India I have come across boiler inspectors come inspect boiler installations on a power plant.
In real estate government authorities perform inspections before issuing Completion Certificate or Occupancy Certificate.
In Middle East it is mandatory for every project the obtain clearance certificates Civil Defence before project facilties are put to use. Most importantly Civil defence inspects the facilities for working of fire protections systems.
Hope this helps
