In a densely built environment, pipeline construction is becoming increasingly complex. Depending on the situation, the subsoil condition and the existing infrastructure, there are now several ways to install pipes below the existing ground level.
Horizontal DrillingThese may include:

  • Installation of pipes through open excavation;
  • Horizontal Directional Drilling HDD
  • Compression methods

For this particular Zafeco provides consultancy for:

  • The necessary soil research
  • Interpretation of soil research results
  • Subsoil modeling
  • Trench excavations and the optimal refill procedure in the trench where the pipeline will be installed
  • Calculation of settlements of an embankment on or near a pipe
  • Calculation of geotechnical parameters around a pipe
  • Consultancy of the installation depth and mud pressures of the Horizontal Directional Drilling
  • Design of possible building pits necessary to drill holes.

Consultancies can be made based on the ASTM or Eurocode 7 depending on the client request and project. The consultancy includes periodic reports and meetings with the client describing the progress, risks doubts and opportunities.
