Looking to take on a new horizontal directional drilling (HDD) project in Roseville, CA? There are several issues you’re going to need to keep in mind, both in the planning phases and in the actual execution of the project.
Here are just a few examples of those issues you’ll want to consider.
Soil type and density
The type of soil you’re working with will have a significant impact on the feasibility of an HDD project, and the alignment and profile of the utility lines. If you’re working with a gravelly type of soil, for example, you’ll need to implement some construction and design mitigation measures—and that’s if the gravel doesn’t make it completely infeasible. You’ll be able to use these mitigation techniques if the soils with gravel are located at a reasonable distance down from the surface of the ground, but if the entire subsurface consists of gravel, you’re probably not going to be able to use HDD as your pipeline installation method.
Again, this is just one example of how a soil type could affect your project. It’s important to research a variety of soil types and get a thorough soil analysis done so you know exactly what you’re working with before you start digging.
Costly change orders
Any time you have to issue a change order related to unexpected subsurface conditions—such as the conditions of groundwater, soil or utilities—these orders are going to be costly. Unfortunately, they happen in more projects than not, so you need to account for this possibility in your bidding. It is helpful to conduct a pre-construction HDD design study so you can lower the risk of potential surprises and create more accurate plans for the job. The more information you have available to you, the less money and time you’ll waste in the project.
Operational stresses and installation forces
It’s imperative that you have a thorough understanding of operational stresses and installation forces if you’re going to have a well-planned and safe HDD project. Carefully consider the profile and alignment of your HDD so you can reduce installation forces as much as possible and ensure your pipeline will be able to safely operate within the tolerances called for by design code.
As an example, a pipe of any given material, diameter, thickness and material strength has limits to how much it can bend before it fails. You must take these factors into account when designing any vertical or horizontal curves in an HDD installation to prevent the product pipe from becoming overstressed and damaged during the installation process—this will save you from having to spend money to fix any broken pipes, and help you save time that would be spent stalling the project to make the necessary repairs.
These are just three of the most important issues to consider when preparing for horizontal directional drilling in Roseville, CA. To learn more about the processes associated with these types of projects, contact the team at Es7 Comm-2 U, Inc. today.
