Engineering for cables and pipelines

From KLIC notification and trial trench to a buildable design. One team, one file.

Trayect produces engineering drawings and route plans for grid operators, contractors and engineering partners. You follow every step live in our client portal.

Engineering for cables and pipelines:

  • Route engineering
  • Trial trenches
  • KLIC notifications
  • CROW 500 interfaces
  • Drilling plans
  • Permits
  • Surveying
  • As-built drawings
  • NLCS
Who we work for

Engineering that works in the trench, not just on paper.

We work for parties who need a cable or pipeline project to succeed. Whether you manage the grid, carry out the work or commission it: you get one point of contact and a design tested in the field.

For contractors and grid operators

Buildable drawings to NLCS and the grid operator’s requirements, with interfaces agreed in advance. No surprises during construction.

  • A1MV, LV, gas, water and data routes
  • A2Trial trenches and surveying by our own team
  • A3Priority for outages and hard deadlines

For municipalities and developers

From an initial route study to permit and handover file. You see in advance what is in the ground, what the project affects and which steps are needed.

  • B1Route study and feasibility with alternatives
  • B2Site conditions: soil, nature, archaeology, UXO
  • B3Permits and coordination with third parties

Services

One partner for drawing board, field and permit.

Available separately or as a complete package. Because design and fieldwork sit with one team, what we find in the trench goes straight back into the design.

What we draw, we have seen first.

Every drawing matches the situation in the field. Where the KLIC data leaves doubt, we dig a trial trench and survey the position, so the design rests on facts.

Process

Six phases, from request to handover.

Each phase has a fixed deliverable. At three moments we ask for your formal approval: the preliminary design, the detailed design and the handover file. You follow everything live in your project file.

Tracé · 1:500Phase 1 / 6
  1. 01

    Intake and KLIC notification

    You submit the assignment: the intended route or the request to determine it. We file the KLIC notification and read the delivery straight away, per grid operator and per theme.

    Site conditions quickscan

    The route is checked for soil, groundwater, nature, archaeology, UXO and ownership. One outcome per topic and, where needed, a next step.

  3. 03Your approval

    Preliminary design (PD)

    A second engineer reviews the PD before it reaches you. You approve it in the portal, with name, time and version recorded.

    Trial trenches and surveying

    Where the subsurface is uncertain, we dig a trial trench and survey. What we find goes straight back into the design.

  5. 05Your approval

    Detailed design and permit

    Interfaces get a risk class under CROW 500 and a measure. Permit applications run in parallel.
