Here in Thailand, almost all condominium buildings are constructed of concrete and steel. They use a post and beam structure of reinforced concrete with brick and mortar walls. Pilings are set deep into the ground and tie into a substructure that supports the building.
The structure of the building will last far longer than the economic life of the individual components. This type of construction is strong but the main reason they use it is because of the weather in Thailand. The question of “useful life of a Thai condominium building” sometimes comes up in conversation.
Over time, due to wear and tear, those individual components beak down and need repairs or replacement. Knowing the age of a building will give you an idea when they’ll likely need maintenance and replacements again.
