utility lines is among the most responsible tasks in civil engineering and utility line construction. Beneath the ground, gas, water, electricity, district heating, and telecommunications lines often run in very confined spaces. Even accidental damage can have serious consequences\u2014ranging from service interruptions and significant property damage to immediate danger to employees and third parties. This makes it all the more important to identify potential risks before construction begins and to plan appropriate protective measures well in advance.   <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#ffffff;font-size:20px\">Therefore, a GW129 training course does not focus solely on teaching technical regulations. Equally important is understanding how the theoretical requirements can be applied safely and practically to various construction site situations. Structured work planning, awareness of potential hazards, and responsible conduct by all parties involved form the foundation for safe construction.  <\/p>\n\n\n\n<div style=\"height:16px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#ffffff;font-size:20px\">Schaufelmann GmbH conducts its GW129 seminars exclusively as live training sessions\u2014either online or in-house. Experienced trainers present the material using practical examples, explain typical situations encountered in everyday construction site work, and are available to answer participants\u2019 technical questions throughout the training. The training concludes with a written exam. Upon successful completion, participants receive their personal GW129 certificate as proof of qualification, valid for three years.   <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<style>.gw-img-zielsetzung img{width:100%;aspect-ratio:612\/329;object-fit:cover;display:block}<\/style>\n\n\n\n<figure class=\"wp-block-image size-full has-custom-border gw-img-zielsetzung\"><img decoding=\"async\" src=\"https:\/\/gw129-seminare.de\/wp-content\/uploads\/2026\/09\/gw129-schulung-schachtarbeiten.png\" alt=\"GW129 Hands-On Training\" style=\"border-radius:20px\"\/><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#ffffff;font-size:20px\">On this information page, we have compiled important topics covered in GW129 training that are particularly important for the safe handling of utility lines.

This includes up-to-date utility line information from the respective utility providers and a careful review of existing as-built documentation. At the same time, the construction site must be set up and operated in such a way that employees, road users, and third parties are not endangered.  <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\">\n<div style=\"display:flex;align-items:center;gap:12px;margin-bottom:14px\">\n  <span style=\"flex-shrink:0;display:inline-flex;align-items:center;justify-content:center;width:36px;height:36px;border-radius:50%;background:#e3051b;color:#fff;font-weight:900;font-size:20px\">01<\/span>\n  <span style=\"font-weight:900;font-size:20px;text-transform:uppercase;color:#e3051b\">Obligations of the Contractor<\/span>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-color\" style=\"color:#111318;font-size:clamp(26px, 2.2vw, 36px);font-weight:700;line-height:1.16\">Responsibility begins even before construction starts<\/h2>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">Careful work planning is one of the most important prerequisites for working safely in the vicinity of utility lines. Even before a construction project begins, construction companies are responsible for identifying potential hazards and taking appropriate measures to protect employees, residents, and existing utility lines. Much of the damage to underground lines does not occur during the actual construction work, but rather as a result of inadequate planning or a lack of information beforehand.  <\/p>\n\n<input type=\"checkbox\" id=\"gw-more-art01\" class=\"gw-more-toggle\" style=\"position:absolute;opacity:0;pointer-events:none\">\n<div class=\"gw-more-content\">\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">Among the most important obligations of a construction company are, in particular, the duty to investigate and the duty to ensure safety. Both are intended to identify hazards early on and ensure that construction projects proceed safely. In the GW129 training course, these obligations are not considered in isolation but are taught as part of responsible construction site management.  <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">Hazards must be assessed and appropriate protective measures established. These include adequately sized safety distances from moving traffic, appropriate protective equipment, and organizational measures to ensure that the work is performed safely. If the available space is insufficient, additional protective measures must be provided.  <\/p>\n\n\n\n<div style=\"display:flex;gap:14px;align-items:flex-start;background:#fdeceb;border-radius:14px;padding:20px 24px;margin:24px 0 0\">\n  <span style=\"flex:0 0 auto;display:inline-flex;align-items:center;justify-content:center;width:28px;height:28px;border-radius:50%;background:#e3051b;color:#fff;font-weight:900;font-size:16px\">!<\/span>\n  <div>\n    <p style=\"margin:0 0 4px;font-weight:900;font-size:15px;color:#e3051b;text-transform:uppercase;letter-spacing:.3px\">Practical Knowledge from the GW129 Training Course<\/p>\n    <p style=\"margin:0;font-size:15px;color:#303742;line-height:1.5\">A safe construction site isn&#8217;t created only when construction equipment is brought in.

Its purpose is to protect road users, workers, and bystanders from hazards that may arise from a construction site. Simply installing traffic signs and barriers is not sufficient. It is crucial that the entire work site be properly secured throughout the construction period, regularly inspected, and, if necessary, immediately adapted to changing conditions.   <\/p>\n\n<input type=\"checkbox\" id=\"gw-more-art02\" class=\"gw-more-toggle\" style=\"position:absolute;opacity:0;pointer-events:none\">\n<div class=\"gw-more-content\">\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">On workdays, work sites must be inspected at least twice a day. On non-workdays, at least one inspection is required. In addition, inspections must be conducted immediately if exceptional events, such as storms or severe weather, have affected traffic safety.  <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">Only traffic signs that are clearly visible can fulfill their protective function. Traffic signs with severely damaged reflective sheeting must not be used. As a general guideline, traffic signs with more than 20 percent of their reflective surface damaged must no longer be used.

Power lines may run visibly above the construction site as overhead lines or lie underground as buried cables. In both cases, safety distances must be strictly observed, and any damage can have life-threatening consequences.  <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">If a power cable is damaged or there is reason to suspect damage, extreme caution is required. People outside the affected machine must be instructed to keep their distance. The operator\u2019s cab must not be touched and must under no circumstances be left without careful consideration. There may be a risk of death in the area known as the \u201cvoltage funnel.\u201d   <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;font-weight:700;line-height:1.61\">The GW129 training course teaches these rules of conduct in a practical manner and explains why acting calmly is crucial in the event of an accident. Quick but well-considered decisions can help prevent further hazards. <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">When working near live overhead power lines, the required safety distances must be observed. Contact with or damage to a high-voltage power line does not necessarily result in the line automatically becoming de-energized. Therefore, potential hazards posed by overhead power lines must be taken into account as early as the construction site planning phase.  <\/p>\n\n\n\n<div style=\"display:flex;gap:14px;align-items:flex-start;background:#ffffff;border-radius:14px;padding:20px 24px;margin:24px 0 0\">\n  <span style=\"flex:0 0 auto;display:inline-flex;align-items:center;justify-content:center;width:28px;height:28px;border-radius:50%;background:#e3051b;color:#fff;font-weight:900;font-size:16px\">!<\/span>\n  <div>\n    <p style=\"margin:0 0 4px;font-weight:900;font-size:15px;color:#e3051b;text-transform:uppercase;letter-spacing:.3px\">Practical Knowledge from the GW129 Training Course<\/p>\n    <p style=\"margin:0;font-size:15px;color:#303742;line-height:1.5\">In the event of an electrical accident, it is not always possible to tell whether a power line is still live.

Damage to them can lead to dangerous situations, especially if gas escapes and mixes with air. To properly assess risks, employees must be familiar with the basic properties of natural gas and the necessary safety procedures.  <\/p>\n\n<input type=\"checkbox\" id=\"gw-more-art09\" class=\"gw-more-toggle\" style=\"position:absolute;opacity:0;pointer-events:none\">\n<div class=\"gw-more-content\">\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">Natural gas is lighter than air and naturally odorless. To make it easier to detect, an odorant is added to it. The flammability range of a gas-air mixture is approximately between 4 and 17 percent. These properties are of great importance for risk assessment on construction sites.   <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;font-weight:700;line-height:1.61\">Work on gas lines may only be performed by qualified, reliable, and trained personnel. The contractor remains responsible for selecting the personnel to be deployed. The GW129 training raises participants\u2019 awareness of the risks involved in working near gas lines and the appropriate actions to take in the event of an accident.  <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">If a gas line is damaged, avoid sources of ignition, evacuate people from the danger zone, and notify the responsible utility company as well as the fire department if necessary. If escaping gas is already burning, there is not automatically a risk of explosion at that moment. If no people need to be rescued and no additional danger is posed, a gas flame should not be extinguished on one\u2019s own initiative.  <\/p>\n\n\n<\/div>\n\n<\/div>\n<label for=\"gw-more-art09\" class=\"gw-more-label\"><\/label>\n<\/div>\n<\/div>\n\n<div class=\"wp-block-group alignfull has-light-gray-background-color has-background is-layout-constrained wp-container-core-group-is-layout-77c14012 wp-block-group-is-layout-constrained\" id=\"artikel-10\" style=\"padding-top:56px;padding-right:clamp(24px, 5vw, 96px);padding-bottom:56px;padding-left:clamp(24px, 5vw, 96px)\">\n<div class=\"wp-block-columns alignwide are-vertically-aligned-top is-layout-flex wp-container-core-columns-is-layout-937dc912 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62.5%\">\n<div style=\"display:flex;align-items:center;gap:12px;margin-bottom:14px\">\n  <span style=\"flex-shrink:0;display:inline-flex;align-items:center;justify-content:center;width:36px;height:36px;border-radius:50%;background:#e3051b;color:#fff;font-weight:900;font-size:20px\">10<\/span>\n  <span style=\"font-weight:900;font-size:20px;text-transform:uppercase;color:#e3051b\">Work on Water Lines<\/span>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-color\" style=\"color:#111318;font-size:clamp(26px, 2.2vw, 36px);font-weight:700;line-height:1.16\">Prevent Water Damage and Hazards Caused by Compressive Forces<\/h2>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#303742;font-size:18px;line-height:1.61\">At first glance, water pipes seem less dangerous than electrical or gas lines.

GW129 training helps companies prepare their employees for these requirements and better identify risks in day-to-day construction site operations. <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#ffffff;font-size:20px;line-height:1.55\">The topics covered on this page illustrate just how diverse the requirements are: from contractors\u2019 obligations and ensuring public safety, to the duty to investigate and damage prevention, all the way to the proper course of action in the event of damage to fiber-optic, electrical, gas, water, or district heating lines. It is not only crucial to know the individual rules, but also to understand their significance for practical construction work. <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#ffffff;font-size:20px;line-height:1.55\">Schaufelmann GmbH delivers this content through a live training course led by instructors with hands-on experience.

After successfully passing the written exam, participants receive their GW129 certificate as proof of qualification, which is valid for three years.  <\/p>\n\n\n\n<p class=\"has-text-color wp-block-paragraph\" style=\"color:#ffffff;font-size:20px;line-height:1.55\">If you\u2019d like to do more than just read through the material\u2014if you\u2019d like to learn it in a structured and practical way\u2014you\u2019ll find the latest dates and registration information for the GW129 training course on our website.<\/p>\n\n\n\n<style>.gw-summary-btn{width:260px;box-sizing:border-box;text-align:center}\n.gw-summary-btn.wp-block-button .wp-block-button__link{width:100%;box-sizing:border-box}\n.gw-btn-ghost-white.wp-block-button .wp-block-button__link{background:transparent!important;color:#ffffff!important;border:1px solid #ffffff;padding:17px 27px!important;box-sizing:border-box;transition:background .15s ease,border-color .15s ease}\n.gw-btn-ghost-white.wp-block-button .wp-block-button__link:hover{background:#a30510!important;border-color:#a30510!important}\n@media (max-width:600px){.gw-summary-btn{width:100%}}\n<\/style>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-container-core-buttons-is-layout-3f825228 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button gw-btn-primary gw-summary-btn\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/gw129-seminare.de\/en\/gw129-online-training-dates-registration\/\">Book a training session now<\/a><\/div>\n\n\n\n<div class=\"wp-block-button gw-btn-ghost-white gw-summary-btn\"><a class=\"wp-block-button__link wp-element-button\" href=\"\/#termine\">View Dates<\/a><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<style>.gw-summary-photo{width:100%;aspect-ratio:3\/2;overflow:hidden;border-radius:20px;margin-bottom:20px}\n.gw-summary-photo img,.gw-summary-photo picture{width:100%;height:100%;object-fit:cover;display:block}<\/style>\n<div class=\"gw-summary-photo\">\n  <img decoding=\"async\" src=\"https:\/\/gw129-seminare.de\/wp-content\/uploads\/2026\/09\/gw129-seminar-trainer-teilnehmer-praesenz.jpg\" alt=\"Trainer at a GW129 live training session with participants\"\/>\n<\/div>\n\n\n\n<style>.gw-exclusive-card{background:#fff;border-radius:18px;padding:32px;box-sizing:border-box;display:flex;align-items:center;gap:20px}\n.gw-exclusive-text{flex:1 1 58%;min-width:0}\n.gw-exclusive-text h3{margin:0 0 16px;font-size:clamp(22px, 1.95vw, 37px);font-weight:700;line-height:1.07;letter-spacing:-0.46px;color:#111318}\n.gw-exclusive-text p{margin:0 0 18px;font-size:22px;font-weight:700;line-height:1.19;letter-spacing:-0.46px;color:#303742}\n.gw-exclusive-bullets{display:flex;flex-direction:column;gap:12px}\n.gw-exclusive-bullets div{display:flex;align-items:center;gap:10px}\n.gw-exclusive-bullets span.dot{flex:0 0 auto;display:inline-flex;align-items:center;justify-content:center;width:22px;height:22px;border-radius:50%;background:#e3051b;color:#fff;font-size:13px}\n.gw-exclusive-bullets span.txt{color:#303742;font-size:22px;letter-spacing:-0.46px}\n.gw-exclusive-imgwrap{flex:0 0 38%;max-width:38%;display:flex;justify-content:center}\n.gw-exclusive-imgwrap img{width:100%;height:auto;aspect-ratio:233\/309;object-fit:cover;border-radius:8px;transform:rotate(5deg);filter:drop-shadow(0 10px 18px rgba(17,19,24,.28));display:block}\n@media (max-width:781px){\n  .gw-exclusive-card{flex-direction:column;text-align:left}\n  .gw-exclusive-text{flex-basis:auto}\n  .gw-exclusive-imgwrap{flex-basis:auto;max-width:180px}\n  .gw-exclusive-text h3{font-size:26px}\n}\n<\/style><div class=\"gw-exclusive-card\"><div class=\"gw-exclusive-text\"><h3>Exclusive for Seminar Participants<\/h3><p>You can find detailed information on GW129 in our <strong>participant brochure<\/strong>.<\/p><div class=\"gw-exclusive-bullets\"><div><span class=\"dot\">\u2713<\/span><span class=\"txt\">A summary and reference guide for later.<\/span><\/div><div><span class=\"dot\">\u2713<\/span><span class=\"txt\">Available in 15 languages!<\/span><\/div><\/div><\/div><div class=\"gw-exclusive-imgwrap\"><img decoding=\"async\" src=\"https:\/\/gw129-seminare.de\/wp-content\/uploads\/2026\/08\/broschuere-cover-hires_1.png\" alt=\"GW129 participant brochure\"\/><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<script>\ndocument.addEventListener('DOMContentLoaded', function () {\n  function syncLabel(cb) {\n    var lbl = document.querySelector('label[for=\"' + cb.id + '\"].gw-more-label');\n    if (!lbl) return;\n    lbl.textContent = cb.checked ?
