Trenching and excavation are major cost drivers in an underground cable laying project, often accounting for a significant portion of the total price.

• Difficulty of Excavation: The type of soil, the presence of rock, or the need to cut through concrete or asphalt will require different equipment (e.g., rock breakers instead of standard excavators) and more labor time, increasing costs.

• Depth and Width: Projects requiring deeper or wider trenches, especially for multiple cables or ducts, will have higher excavation and backfilling costs.

• Spoil Disposal: The cost of removing excavated soil (spoil) from the site and transporting it to a designated disposal area can be a significant line item, particularly for large-scale projects.
