The ESIC is applicable if you are doing any additional construction work on the premises of the factory. If your factory is newly set up or if an employee compensation policy is in place, for new construction, ESIC is not applicable. However, if construction activity is carried out in a factory where the workers working on the premises are covered under ESIC, then the said construction activity falls under the provisions of the ESIC Act.
