Network location and cable identification in Bavaria and Baden-Württemberg
On every industrial site that has grown over the years there are lines only the ground still knows: laid decades ago, documented on paper nobody can find. CFT traces such routes from the surface, marks them and surveys them in – and where five cables lie side by side in the open trench, cable identification says which one is yours.

What we do on site
We close the gaps in the as-built documentation section by section: which section comes first and whether isolation is needed is agreed before the appointment. Each section is marked, sketched and documented in its own right – so that outside contractors can be briefed in writing instead of by shouted instruction.

For you as a business
Every construction job on the premises starts with the same question: where may we dig? As long as the answer rests on memories, the company carries the risk. Traced and documented section by section, it becomes a written basis – for your own maintenance as much as for briefing outside contractors. And cable identification prevents the classic emergency: cutting the wrong cable because in the trench they all look the same.
How the job runs
- You name the section and the occasion; whether isolation is needed is agreed before the appointment.
- Lines that carry a signal are traced with transmitter and receiver, non-conductive ones with sonde or ground-penetrating radar.
- The route is marked at the surface and, on request, surveyed in with GPS or total station.
- In the open trench, cable identification confirms the target cable beyond doubt – before the cut.
- You receive marking, route sketch, documentation and the survey points in your formats.
Equipment and methods
Electromagnetic location puts a signal on the line and follows it at the surface – clamped on directly where access exists, inductively where not. Plastic pipes receive a traceable sonde or are found acoustically; the rest is handled by ground-penetrating radar. Cable identification works at the exposed bundle: the applied signal proves the target cable unambiguously before anyone disconnects.
What you receive
Marked routes at the surface, a route sketch and documentation as PDF, plus the surveyed points as .shp, .gpkg, .dwg and .dxf. Each section is documented and filable in its own right.
Costs and effort
We charge by deployment time from Erding, planned section by section. Location is most economical bundled – several sections in one day – or directly ahead of construction work, when the marking is needed at once.
Frequently asked questions
Does anything have to be switched off for the location?
Usually not – tracing normally happens on the live cable. Only cable identification before a cut and certain clamp-on situations need coordination with your qualified electrician; we settle that before the appointment.
Does the location also find abandoned lines?
Yes, as long as they are metallic: the signal is applied to dead cables and pipes directly or inductively. Pure plastic lines without a tracer wire are a case for sonde or ground-penetrating radar.
Can the results be taken into GIS?
Yes – the surveyed points come as .shp, .gpkg, .dwg or .dxf. Whoever wants to build up the whole record combines network location with as-built capture: locate, survey, keep updating.
Describe the findings.
The more precisely you describe the findings, the more directly we can go to work. Plans, readings and photos help us settle the method in advance.
What happens next
- We read your message and match the case to a method.
- We come back to you – usually with a question that shortens the appointment.
- We confirm the appointment and what it costs before anyone sets off.
