Model construction, in Dublin, denotes the act of making replica of designs, architectures, sculptures or individuals typically in wax. Sometimes such models may be prepared first in order to guide the construction of the actual structure, which would be far bigger than the model. Models are generally made of wax, plastics or plywood, depending on the shape & flexibility needed. Many people construct such models as a hobby, rather than profession. However, construction projects & museums in Dublin often hire such personnel for constructing the desired models.
