in utility survey
At TerraCarta, we specialize in accurately locating and recording cables and pipes. Our operations are entirely focused on this field. Here we use advanced techniques and our years of experience to map cable and pipeline networks under the ground, roads, railroads and waterways. With our expert team of over 75 employees, we are able to carry out any project efficiently and reliably.
expertise in
Utility survey
TerraCarta has in-depth knowledge and experience in the field of utility survey, focusing on the following key areas:
Advanced techniques
We apply techniques such as digging, detecting and mapping to locate and record cables and pipes with certainty.
Communication with grid operators
We maintain close contact with grid operators to ensure that our information is up-to-date and accurate.
Permit management
Our experts handle the necessary permits for excavations, road closures, and work on rail and waterways. Safety is at the heart of this.
Legal frameworks
We work entirely according to the guidelines of the WIBON and CROW 500, ensuring that all our projects comply with the applicable laws and regulations.
roadmap for
Utility survey
TerraCarta offers custom solutions for various branches of construction, including:
- Collect available information on underground infrastructure.
- Detecting cables and pipes using techniques such as ground penetrating radar and radio detection.
- Interpret detection data to obtain a complete overview of the subsurface.
- Mapping: Preparation of accurate maps showing all underground cables and pipes.
- Compare the new data with existing information to detect any discrepancies.
- Verify results by test trenching or other validation methods.
- Communicate findings to concerned parties, such as grid operators and contractors.
Detection of
cables and pipes
Cables and pipelines frequently deviate from the position they are in on drawings. To prevent damage and avoid delays during projects, it is very important to accurately locate this underground infrastructure. TerraCarta uses modern techniques such as ground penetrating radar and radio detection, which allow us to draw a detailed picture of the subsurface, even down to a depth of 10 to 20 meters. Our detection methods ensure that excavation and construction projects can be carried out without unexpected obstacles.
Design phase and the
CROW-500 guidelines
In the design phase of any construction or excavation project, it is essential to accurately map the location of cables and pipes. The CROW 500 guideline emphasizes that cables and pipes must be physically located before the design can be finalized. By using our detection methods at this stage, you avoid running into problems later, such as unforeseen obstacles that delay the project and cause additional costs. TerraCarta provides reliable data you can rely on during the design process. With TerraCarta’s data, a design becomes a manufacturable design.
Implementation phase: prevent excavation damage
with KLIC registration
Before excavation work starts, it is a legal requirement to make a KLIC (The Netherlands’ Centre for Utility Information) registrations, as stipulated in the WIBON Act. This notification provides information about the cables and pipes present at the site, but this data must always be verified. TerraCarta offers support in verifying this KLIC data and helps you report discrepancies to the Land Registry, as required by the WIBON. This not only prevents excavation damage, but also unnecessary delays and safety risks.
