Limitations of using Open cut Method
Open cut, or trenching, is the most common way to install and connect utilities, but it has some
limitations. This method can only be used when the ground above the utilities can be disturbed and
there are no buildings, roadways or other obstructions in the way. Directional boring can be used in
the same situation where open cut excavation is planned, but it can also be used to go under roads,
sidewalks, rivers, even houses if there is a need for it.
The installation cost for trenching versus directional boring is usually lower, in the range of six to
eight times less than horizontal drilling. These two technologies usually complement each other;
trenching or plowing being more cost-effective but having limitations and directional boring taking
care of everything else but at a higher cost. If we wanted to choose one over the other without cost
as a factor, directional boring or horizontal directional drilling would be selected as the best
alternative, doing everything trenching and plowing can do and jobs once thought impossible
before this great technology.
