ISO 14001 requirements for construction company

Answer:

ISO 14001 doesn't have such specific requirements for the construction sites or any other type of business. But, if such activity is defined by the organization as an operational control for handling waste, it is compulsory to follow this control, otherwise it would be considered as nonconformity.

If you are their subcontractor, you must follow their rules on the construction site as well as their own employees.
