Dial Before You Dig Online FAQ’s

Dial Before You Dig Online allows registered users to view locations where they are excavating or planning works to check if there are Gas Networks Ireland assets in the area.  It allows registered users to print maps showing the location of Gas Networks Ireland assets. 

Dial Before You Dig Online allows registered users self-service access to the location of Gas Networks Ireland assets. Users can then assess if there is gas infrastructure in the vicinity of their works. Dial Before You Dig Online is a 24 hour service, available 7 days a week, 365 days a year.

Please call our Dial Before You Dig Service on 1800 42 77 47 or email dig@gasnetworks.ie if you have a question about the gas map.

Critical Activity relates to the type of dig you are undertaking. It is important that you choose the correct one. There are four Critical Activities to choose from.

Quarrying/Blasting
Any activity that involves quarrying and or blasting within 400m of the Gas Networks Ireland network.

Demolition
Any demolition activity within 150m of the Gas Networks Ireland network. This could involve use of explosives, a ball and chain or excavation equipment.

Piling
The use of piling activity within 15m of the Gas Networks Ireland network. This could involve hydraulic, vibration, pneumatic or screw piles.

Trenchless Technique
The use of trenchless techniques such as moling or directional drilling within 10m of the Gas Networks Ireland network.

You must contact Gas Networks Ireland on 1800 42 77 47 before excavating in the vicinity of the a 400PE medium pressure pipeline. Excavation works in the vicinity of the 400PE must be supervised by Gas Networks Ireland.

Yes. Refer to the Gas Networks Ireland Safety Advice Booklet and the HSA Code of Practice For Avoiding Danger From Underground Services.

Yes. Before you commence any excavation, you must print a current gas network map(s) at an appropriate scale, and it must be retained on site while work is under way.

When planning an excavation, use 1:1000 scale maps for the level of detail required at the proposed location, in preference to 1:2500 or 1:5000. Low-scale maps (i.e. 1:2500 and 1:5000) may not give an appropriate indication of some annotation, location or configuration of underground services. 1:1000 scale presents the most information, other scales are provided for overview purposes and present information appropriate to each scale.

No, maps are only available to print on Ordnance Survey mapping.

You can bookmark as many locations as you like during your session. Once your session ends after 30 minutes of inactivity, or you log out, your bookmarks will disappear.

Recorded information of the gas network on Dial Before You Dig Online is updated on weekly basis.

Please note that it can take a number of weeks to process as-laid records for newly laid gas pipes. Watch out for signs of recently laid gas pipes and other underground services on site. The absence of gas pipes should never be taken as proof that the area in question is free of underground gas pipes.
