Dial Before You Dig Record

What Is a Dial Before You Dig Record?

A Dial Before You Dig Record is a formal document used by Australian construction businesses, tradespeople, and homeowners to track and verify the location of underground infrastructure before excavation begins. While many people think of this service as just a phone call or a website enquiry, the "Record" itself is the physical or digital proof that a business has followed the necessary steps to identify and manage underground hazards.

In most Australian workplaces, this record does not stand alone. It functions as a critical appendix to a Safe Work Method Statement (SWMS) or a Job Safety Analysis (JSA). It connects the theoretical data provided by utility owners with the physical reality of a construction site. The document proves that a site supervisor not only requested the plans but also verified them on the ground before allowing an excavator or digging machinery to start work.

The primary purpose of this record is to prevent damage to essential infrastructure like telecommunications cables, gas mains, water pipes, and electricity lines. More importantly, it is a vital tool for meeting Work Health and Safety (WHS) obligations. Under Australian law, hitting a live gas pipe or high-voltage cable is not just an expensive inconvenience; it is a potential breach of safety laws that can lead to significant fines or prosecution.

When to Use This Document

You must use a Dial Before You Dig Record whenever you intend to break ground. This applies to projects of all sizes, from a major civil engineering cut to a simple residential landscaping job. If a post-hole digger, auger, trencher, or excavator is going into the soil, you need this record.

Specifically, Australian regulations require rigorous documentation when the work is classified as "High Risk Construction Work" (HRCW). According to the Model WHS Regulations, excavation work deeper than 1.5 metres usually falls into this category. When work is classified as high risk, you are legally required to have a written SWMS. The Dial Before You Dig Record serves as the evidence that you have identified the specific hazards associated with that excavation.

There are also specific legal triggers in different states that dictate when you must use this process. For example, under the Electricity Supply Act 1995 (NSW), you must not dig near electricity cables without specific authority. In Victoria, the Occupational Health and Safety Act 2004 requires employers to maintain safe systems of work, which explicitly includes the identification of underground services.

Even for shallow digging, such as installing a letterbox or fence, best practice dictates using the Before You Dig Australia (BYDA) service. The record helps you manage the "design purpose only" limitation of the plans you receive. It creates a paper trail showing that you checked for pipes before you dug.

Key Sections and Required Elements

To be effective in a legal or professional setting, a Dial Before You Dig Record must contain more than just a map of the street. It needs to be a comprehensive log of the entire risk management process. If you are using a project management template to build this record, ensure it includes the following five sections.

Section 1: Project & Inquiry Details

This section links the paperwork to the physical job site. It must include the unique BYDA Reference Number (also known as the Request ID). This number is the only way to trace the enquiry back to the specific data provided by the asset owners. You should also record the work address, the Lot and DP (Deposited Plan) number, and the date of the inquiry.

Crucially, you must list the Asset Owners contacted. This might include Jemena, Telstra, Ausgrid, or local water authorities. Listing them confirms that you have consulted the relevant authorities for that specific location.

Section 2: Plan Validity & Scope

Plans provided by BYDA are not valid forever. This section must state the date the plans were issued and their expiry date. Standard industry practice treats these plans as valid for 30 days, though some asset owners have different rules.

You must include a specific disclaimer in this section. It should state that the plans are for "design purposes only" and must not be used for excavation without verification. This clause protects your business by acknowledging the limitations of the data you received.

Section 3: On-Site Verification (The "Quality Level" Declaration)

This is the most important part of the record for WHS compliance. It details how you verified the information on the plans. Australian Standard AS 5488:2019 classifies subsurface utility information into "Quality Levels."

• QL-D: Information from records only (the BYDA plans).
• QL-B: Information obtained through remote sensing, such as using a Cable Avoidance Tool (CAT) and Genny (Signal Generator).

Your record should specify which Quality Level applies to the data you are using. It needs a checklist confirming that electronic locators were used, visual indicators (paint or pegs) were identified, and if necessary, potholing (hydro vacuum excavation) was performed to physically expose the pipes.

Section 4: Hazard Identification & "No Dig" Zones

You must define exclusion zones on the record. This is a diagram or text field outlining the "Service Corridor." This is the area where machinery is prohibited, and hand digging only is permitted.

Under the Code of Practice: Excavation Work, you must identify the "No Go Zones." These zones usually extend a specific distance from the located service, often ranging from 500mm to 1.5 metres depending on the state and the type of asset. Marking these zones on the record proves you planned to keep machinery a safe distance away.

Section 5: Employee Acknowledgement

The final section is for the crew. It is a declaration that the workers have been briefed on the location of underground services. It should read something like: "I acknowledge that I have been briefed on the location of underground services and understand the emergency stop procedures."

It requires the signatures of all excavation crew members. This is your legal evidence that the workers were informed of the hazards before they started work.

How to Write a Dial Before You Dig Record (Step by Step)

Creating a robust record involves a clear workflow. You should not just fill out a form at the end of the job. Follow these steps to ensure your documentation is legally sound and practically useful.

Step 1: Lodge the Inquiry Online

Go to the Before You Dig Australia (BYDA) website and submit your enquiry. You will need to provide the location details and the scope of work. Once you submit the request, you will receive plans and information from various asset owners via email. Save these PDFs immediately. Print them or save them to a tablet that will be used on-site.

Step 2: Review the Plans

Sit down with the plans and identify the potential hazards. Look for the symbols representing gas, water, electricity, and telecommunications. Note the "legend" on the drawings, which will tell you what the different coloured lines and symbols mean.

Step 3: Conduct On-Site Verification

Take the plans to the site. Use your electronic locating equipment (CAT and Genny) to trace the services shown on the plans. Mark the ground with paint or flags. Compare what you find on the ground with what is on the plans.

If there is a discrepancy, or if the depth is critical, you may need to use "potholing." This involves using hydro vacuum excavation to dig a small hole to physically expose the pipe and confirm its depth and location.

Step 4: Complete the Record

Fill out your Dial Before You Dig Document. Enter the BYDA Reference Number and the list of asset owners. Check the boxes indicating that you used electronic locators and visual markers.

Define your "No Dig Zones" based on the locations you found. If a pipe is running through the middle of a trench, mark the corridor where the excavator bucket cannot go.

Step 5: Brief and Sign

Hold a toolbox talk with your workers. Show them the plans and the markings on the ground. Explain the exclusion zones and what they need to do if they accidentally hit a pipe (usually stop work immediately and call the asset owner).

Once everyone understands the plan, have them sign the Employee Acknowledgement section of the record. The site supervisor or leading hand must also sign and date the document to verify that the physical locations on the ground match the plans.

Common Mistakes to Avoid

Many businesses treat the Dial Before You Dig process as a tick-a-box exercise. This approach creates significant risk. Here are the most common mistakes and how to avoid them.

Relying Solely on the Plans

The biggest error you can make is treating the BYDA plans as "ground truth." The plans are based on historical records and often lack accuracy regarding depth or exact lateral alignment. Excavating without on-site physical verification is a breach of your WHS duties. The plans are a guide, not a guarantee. You must always verify their location on the site using a locator.

Missing "No Go" Zone Definitions

Failing to mark the "Designated Zone" creates liability. If a worker hits a service because you did not define where they could and could not dig, the business is responsible. Your record must clearly show these exclusion zones. Do not rely on workers to "guess" a safe distance.

Ignoring Safety Clearances

The record must verify that safe clearance distances are maintained. These distances vary. Some asset owners require a 500mm clearance, while others require 1.5m or more. You need to check the specific requirements for the assets you are working near and record those distances on your form.

Using Outdated Plans

Plans older than 30 days (or the asset owner's specific validity period) should not be used. Infrastructure changes constantly. New pipes are laid, and old ones are decommissioned. If the plans are old, lodge a new inquiry before you start digging. Using expired data is a clear sign of negligence.

Legal Considerations (AU)

Compliance with Dial Before You Dig protocols is not just good practice; it is a requirement under various Australian laws. Understanding these legal frameworks will help you understand why the record is so important.

Work Health and Safety (WHS) Regulations

The Model WHS Regulations classify excavation work as High Risk Construction Work (HRCW) in most jurisdictions. This triggers the requirement for a Safe Work Method Statement (SWMS). A key part of writing an SWMS is identifying all hazards. Your Dial Before You Dig Record is the primary evidence that you have identified the hazard of underground services.

Regulations also require that risk assessment documents be kept for a specific period. You generally need to keep these records until the risk is removed or for up to two years after the work is completed. If a serious incident occurs, these records will be scrutinised by Safe Work inspectors.

Adherence to BYDA Terms of Use

When you use the BYDA service, you agree to their Terms and Use. These terms state that the information is provided for "design purposes only" and must not be used for excavation without verification. Your record must acknowledge that you have met this condition. Failing to do so can leave you open to liability from asset owners if you damage their infrastructure.

Australian Standard AS 5488:2019

While compliance with AS 5488:2019 (Classification of Subsurface Utility Information) is technically voluntary, it provides a strong defense of "due diligence." If an incident occurs and you are taken to court, showing that you followed the Australian Standard is a powerful argument that you took all reasonable steps to ensure safety. The standard helps you define the "Quality Level" of your data, which should be reflected in your record.

State Variations

It is important to note that laws vary by state.

• NSW: The Work Health and Safety Regulation 2017 requires specific identification of underground services. Additionally, the Electricity Supply Act 1995 prohibits digging near electricity cables without authority.
• VIC: The Occupational Health and Safety Act 2004 differs from the national model law. It places a strict duty on employers to provide and maintain a safe workplace, which mandates the identification of underground services as a specific hazard control.
• WA: The Occupational Safety and Health Act 1984 requires safe systems of work. This implicitly necessitates service location recording as part of managing the risk of excavation.

Always check the specific regulations for your state or territory before commencing work.

Frequently Asked Questions (preview)

Do I need a Dial Before You Dig Record for hand digging? Yes. While the risk is lower with hand tools, you still run the risk of hitting a service. In some instances, hand digging is actually required within exclusion zones. You need the plans to know where those exclusion zones are.

How long are the plans valid for? The standard industry practice is 30 days. However, you should check the specific advice provided by the asset owners in their response packets. If work pauses and restarts after this period, you must lodge a new enquiry.

What happens if I hit a pipe? Stop work immediately. Ensure the area is safe. Call 000 if there is a risk to life or property (gas leak or fire). Then, contact the asset owner using the emergency number provided on your plans or the Dial Before You Dig response. You will need to report the incident to your WHS regulator if it results in a serious injury or notifiable incident.

Is the BYDA service free? Yes, lodging an enquiry with Before You Dig Australia is free for users. It is funded by the asset owners to prevent damage to their infrastructure.

Can I use the record for multiple sites? No. Each record is tied to a specific address and enquiry number. If you move to a new site, even if it is just down the street, you must lodge a new enquiry and create a new record.
