Overview

Since 1 June 2019, earthworks contractors were given greater clarity on the requirements they have to comply with for projects which involve earthworks to be carried out in the vicinity of underground telecommunication cables, through the issuance of a standardised set of Earthworks Requirements.

The Earthworks Requirements include a 9-Step Process which need to be complied with by the earthworks contractors prior to the commencement of earthworks. The Earthworks Requirements were jointly developed by IMDA and the relevant Telcos through an industry consultation together with some major contractors.

These requirements aim to minimise the risk of telecommunication cable cut incidents, which have been a leading cause of telecommunication service disruptions in recent years, and to provide greater clarity for both Telcos and earthworks contractors in terms of the requirements to be adopted.

The industry is to ensure compliance with the following 9-Step Process and the Earthworks Requirements so as to prevent damage to underground telecommunication cables.
