More InformationWhy This Training Is Important
A small mistake can have major consequences.
When working near gas, water, electricity, district heating, and telecommunications lines, even small mistakes can have serious consequences. Damaged utility lines not only result in high costs, but can also endanger employees and disrupt service to entire areas.
The GW129 training course provides the necessary expertise to identify risks early, prevent damage, and perform work in the vicinity of power grid facilities more safely.
Damaged lines
Even minor oversights can lead to costly repairs, construction delays, and liability issues.
Employee at risk
Careless behavior or a lack of knowledge puts coworkers at risk.
Service Interrupted
Damage to gas, water, electricity, district heating, or communication lines can affect entire areas.

Working Safely Around
Utility Lines
Beneath every construction site lies infrastructure that people and businesses rely on every day. The GW129 training course provides the knowledge needed to safely plan and carry out work in the vicinity of utility lines.
Excavator operators, machine operators, supervisors, and work planning staff learn to identify risks early on and handle gas, water, electricity, district heating, and telecommunications lines responsibly.
Identifying risks early on not only protects pipelines and facilities, but also the people on and around the construction site, and contributes to safe work processes and a reliable supply.
Why GW129?
- Work on utility lines requires specialized knowledge and a strong sense of responsibility.
- This training is intended for excavator operators, machine operators, supervisors, and work planning staff.
- The course covers the fundamentals of working safely in areas with gas, water, electricity, district heating, and telecommunications lines.
- The goal is to identify risks early on and prevent damage to the pipes.
- The content is based on the requirements of the DVGW GW129 regulations.
- This training program helps companies raise their employees’ awareness of work related to underground infrastructure.
FAQ
Answers to the Most Important Questions
Why is the qualification certificate so important?
Every year in Germany, damage to utility lines and facilities caused by construction machinery amounts to hundreds of millions of euros. It is essential to raise awareness among the personnel carrying out this work in order to prevent damage to property and injury to people, as well as supply outages. The qualification is part of the cross-sector set of rules “Construction Companies in Underground Pipeline Construction – Minimum Requirements” (e.g. DVGW GW 381) and is often required by clients in tenders as part of a voluntary self-commitment.
Who is affected?
Safety when carrying out construction work in the vicinity of utility and disposal facilities fundamentally concerns everyone involved in the construction project.
The seminar is aimed, on the one hand, at workers and supervisors who carry out machine-assisted activities in the immediate vicinity of utility lines and facilities. This also includes machine-assisted work in agriculture, forestry, and landscaping. Workers and supervisors in these fields should therefore also receive regular training including an exam.
Obtaining complete plan information, fully preparing risk assessments, and verifiably instructing personnel all contribute significantly to how safely the work can be carried out. For this reason, those involved in work preparation should also receive regular training and take the exam.
The GW129 seminar is also recommended for workers carrying out non-machine-assisted activities in the immediate vicinity of utility lines and facilities. This applies especially when they are assisting machine operators.
How do I book a date for the online seminars?
The online seminars can be booked with binding effect for the respective date. Simply enter your participants into the booking form on this website. You will then receive a booking confirmation by email with all the important information for taking part.
By when do I need to have paid? What happens if I cannot attend?
The participation fee must be paid no later than 1 day before the training begins. If a participant is unable to attend on the day of the seminar, they can rebook onto another public online seminar. Sending a substitute is also possible and comes with no additional cost.
When does the training start? When should I be online?
On the day of the training, participants log in via the ZOOM software approximately 30 minutes before the start of the training, using their full first and last name along with the password provided. Once attendance has been checked and participants have been briefed, the online seminar begins.
What does the schedule look like on the day of the training?
Using practical case studies and a touch of humor, the relevant topics are conveyed clearly and concisely. Over a period of around 7 hours, several 10-minute breaks and a 30-minute lunch break are held, and the online exam (multiple-choice test) is completed. Participants can ask questions at any time during the training, either verbally or via the chat function, and the trainer is happy to answer them.
How do I receive the certificate?
After attending the seminar and passing the online multiple-choice test, participants receive their certificate as proof of qualification by email. Upon request, the certificate can also be sent by post for a processing and shipping fee of €10.00 plus VAT.
What do I need to know about the online exam (multiple-choice test)?
The online exam takes place directly after the seminar and consists of 20 questions. You will receive your personal access link to the exam along with your booking confirmation. No prior registration is required.
When do I need theoretical training with a 3-year validity period?
We offer the theoretical training and exam with a 3-year validity period and Schaufelmann certificate to all interested parties who have already completed a 5-year and/or 3-year training course with an exam.
Theoretical training and examination may be completed a maximum of two times in a row. After that, it is necessary to complete training and an exam that includes a practical component with a 5-year validity period at a training facility with an excavator damage demonstration system (BSDA).
Interested parties who have not yet attended a GW129 seminar should complete their first training and exam at a training facility with a BSDA.
