Since 1 January 2017, construction sites at the architectural/project completion stage are allowed to carry out quieter forms of work (see list of permitted quieter works in ePortal) on specific Sundays and public holidays. Contractors shall submit an application via ePortal to NEA for the permit to carry out quieter works on specific Sunday and public holidays subject to compliance with stringent conditions specified in the application form and any other conditions imposed by NEA.
