Horizontal directional drilling is becoming widely popular especially in urban areas where the conventional trench-type digging is no longer feasible. The trenchless technology of HDD has really opened doors of opportunity for directional boring companies and utility providers to conduct digging operations almost anywhere. Its ability to perform digging operations without disturbing or causing damage to the surface makes horizontal directional drilling superior to outdated methods.
What is Horizontal Directional Drilling
In simple terms, HDD refers to a trenchless drilling operation. It allows contractors to drill horizontally underground without disturbing the surface. This method creates only two open pits: the entry and exit points of the pipeline. It really doesn’t involve digging across a vast expanse of soil. Thus, the use of a well-equipped and technically capable Colorado directional boring company is recommended in places where the surface cannot be disturbed.
HDD has an influence on three major aspects of the drilling or pipe laying job. These are:
Production and Technical
Trenchless technology has made all these possible:
- Construction of underground utilities under rivers, roads, railways, structures and even parks.
- The time to obtain technical and organizational approvals before the start of the operation is reduced.
- Significant reduction of operating time and cost
- Reduced risks for accidents
Financial and Economic
- Reduced cost of production time and man-hours
- Low energy cost
- Zero restoration cost of existing surface infrastructure and green space
Social and Environmental
- Preservation of the ecological balance and natural landscape of affected areas
- Doesn’t affect the living conditions of residents in affected areas.
Here’s a geographical comparison of important elements if both methods are applied in the same urban digging project:
|Action/Elements||Using Standard Trench Method||Using HDD Method|
|Creating a Channel||Digging is necessary. Causes damage to roads, pavement, landscape & infrastructure||No digging required|
|Effect on Traffic||Major||Minimal to none|
|Project Speed||Extremely slow||Fast. More than twice the speed of the standard method|
|Risk of Damage to Existing Lines||High||Low|
|Processing of Permits||Lots of formalities, different permits have to be obtained, costly & time-consuming||Minimal red tape, fast & less costly
|Damage to Architecture||Yes||No|
|Additional Charges to Ensure Safety||Yes. Trench sides need added support. Needs additional technicians and machinery.||No charge|
|Deep pipe laying possibility||Not possible||Up to 20 meters|
|Volume of Work, Cost, Construction Time|
|Standard Trench Method||HDD – Trenchless Method|
|Heavy excavation work, requires massive equipment and manpower
Long construction time
|Requires 1 drilling rig with 3 – 6 persons
Cost is 30 – 50% cheaper than standard
Shorter construction time because HDD is 2 – 20x faster
|Cost of accidents + consequences
Operating expenses = High
|Risk of accidents = minimal
Operating expenses = Low
|Effects on Man and Environment|
|Irreparable damage to affected areas||None|
|Disrupts traffic||Doesn’t affect traffic|
|Damage to pavement||No damage to pavement|
|Disrupts lives of affected people||Doesn’t affect lives of people in affected areas|
No matter where the project is, the horizontal directional drilling method always stands out in terms of speed and cost. It is also the better approach from an environmental and economic point of view.
If you have an underground utility installation, repair or rehabilitation project, you should always consider a method that offers:
- Less damage to the surface and existing structures,
- The least disruption to the lives and activities of people in affected areas.
All these benefits are available only if you choose the HDD method and with the help of an efficient Colorado boring company.
Start your project by asking directional boring companies for cost and time estimates.
