{slider-general title="What is beforeUdig?" open="false"}

beforeUdig is a referral service for information on underground infrastructure for an identified excavation site given. It puts those who intend to excavate in touch with underground asset owners who are Members of the beforeUdig service. The asset owners respond by providing information, plans, on the location of any underground pipes & cables, along with information on how to work safely and carefully whilst excavating in the vicinity of underground plant.

{slider-general title="Who should use beforeUdig service?"}

Anyone intending to carry out any excavation work should first lodge an enquiry before commencing: Builders, contractors, farmers, excavation companies, councils, landscapers, underground network maintenance workers, plumbers, home owners, and cable and pipe location companies. Even if you are planning any excavation activity in your own backyard, you should contact beforeUdig.

{slider-general title="How does beforeUdig work?"}

Enquiries can be lodged online anytime at or by calling 4000-999-811 during business hours. Upon completion of your enquiry lodgement you will receive a Confirmation Sheet from beforeUdig which provides details of the asset owners affected and enables you to ensure the recorded dig site is correct. The asset owners will then send you plan’s detailing the location of their underground infrastructure.

It is important to note that not all Asset Owners are registered with the beforeUdig service so it is important that you identify and contact any asset owners not listed.

{slider-general title="What type of information is provided?"}

Underground location plans provide information about plant presence only - they do not pinpoint the exact location of the cables and pipes. It is the excavator’s responsibility to visually expose the cable or pipe manually by using hand tools before any construction begins. This is usually completed using the potholing technique and by following the relevant utilities’ instructions. Utilities will provide contact details for further assistance.

{slider-general title="Why should I use the service before I begin excavation?"}

Underground pipes and cables carry vital services such as water, electricity, communications and gas - damaging them can cause widespread disruption and in some cases isolate entire communities from these essential basic services. There is also the risk of personal injury and incurring significant financial penalties if you damage underground infrastructure. beforeUdig is your first step to safe excavation.

{slider-general title="How much does it cost to obtain a location plan?"}

The beforeUdig service gathers information on the possible presence of underground assets in and around your proposed excavation site, and to request plans and locate services, some Utilities and Local Government Organisations charge to supply these services. Please check with the relevant asset owners listed on your confirmation sheet if you require more information on these charges.

{slider-general title="Why are individuals being held financially liable for damage to the networks?"}

There are many incidents of damage to underground networks throughout Singapore each year, costing millions of dollars. Most of this damage occurs as a result of ignorance, carelessness or even blatant disregard for the networks. Individual and company liability for cable and pipe damage has been introduced by many utilities to make individuals take responsibility for avoiding such damage. Litigation activity may be commenced against individuals or companies where negligence can be proved.

{slider-general title="Are all organisations with underground networks covered by the beforeUdig service?"}

Not yet. Presently, most companies with underground pipes and cables in Singapore are part of the beforeUdig service, but not all. However, the service is actively recruiting new members all the time and the aim is to have all companies with underground networks on board in the near future.

{slider-general title="If I have underground assets how can I become a member of the beforeUdig service?"}

We are keen to continue the expansion of the beforeUdig service with the addition of new members.
