The construction process
There are two key methods that will be used to construct the Pipeline. These are the open-cut trench technique and the trenchless technique.
The open-cut trench technique will involve digging soil to form a trench, lowering the pipe into the trench, and backfilling it with the excavated soil. The depth of the trench will vary depending on technical factors such as ground conditions and topography.
Trenchless techniques are used when installing pipelines under railway lines, major roads and riverbeds. Trenchless techniques bury the pipeline at a greater depth than the open-cut technique and will depend on the nature of the feature being crossed. In these cases, we will use methods such as:
