7 HDD project planning tips

If you're planning a horizontal directional drilling (HDD) project, you already know it’s not just about putting a rig in the ground and getting started. There’s a lot that goes into making sure the job runs smoothly, safely, and efficiently.

At Vermeer UK, we’ve been supplying HDD equipment since the early 90's, and we’ve seen what makes a project successful (and what can cause major headaches!). Here’s what you need to be thinking about before you start drilling.

1. Understand your ground conditions

First things first: you need to know exactly what you’re drilling into. Different ground conditions require different tooling and techniques. Clay behaves very differently from rock or sand, and groundwater can throw a whole new set of challenges into the mix (take a look at our in depth guide on soil conditions here).

A proper geotechnical survey will tell you what you're dealing with. You should also check for any existing underground utilities. Ground Penetrating Radar (GPR) and utility mapping should be part of your planning process. Not sure where to start? The National Underground Asset Register (NUAR) is a great resource.

2. Know the regulations

HDD projects in the UK need to comply with strict safety and environmental standards. One key regulation to be aware of is BS EN 16228-3:2014+A1:2021, which lays out safety requirements for HDD equipment. Your machinery should meet these standards, and your crew should be fully trained on best practices.

You’ll also need to consider environmental regulations. If you’re working near a water source, you might need an Environmental Permit from the Environment Agency. HDD is a low-impact method, but things like drilling fluid spills can still cause serious problems if not managed properly.

3. Safety isn’t optional

Every job comes with risks, and HDD is no exception. One of the biggest hazards? Striking an electrical cable. If you’re drilling near power lines, make sure your team is using proper cable strike avoidance systems. The National Grid has detailed guidance on working safely around utilities.

Regular maintenance checks on your equipment are also non-negotiable. A small issue can quickly turn into a major breakdown if it’s not caught early.

4. Plan for efficiency

Good planning can make or break your project. That means:

• Making sure you have the right rig, drill rods, and tooling for the job.
• Accounting for potential ground challenges and having contingency plans.
• Ensuring site access and logistics are sorted before work begins.

Poor planning leads to delays, increased costs, and avoidable mistakes. We see it all the time with contractors pushing ahead without a solid plan and paying the price later.

5. Keep the locals onside

If your project is in an urban area or near residential properties, keeping local businesses and residents informed can save you a lot of hassle. Noise, vibration, and road closures can lead to complaints if people don’t know what’s happening.

A simple letter drop or community meeting can go a long way in preventing issues down the line.

6. Invest in training

The best equipment in the world won’t make up for an untrained crew. Making sure your team knows how to operate HDD machinery properly is key to both efficiency and safety. There are industry-recognised training courses available, and it’s worth investing in refresher courses if your team hasn’t been trained in a while.

7. Final checks and post-project review

Once the job’s done, don’t just pack up and leave. A post-project review is invaluable as it helps you understand what went well and what could be improved for next time. Did you hit any unexpected issues? Were there delays that could have been avoided? Learning from each project will make future jobs even smoother.

At Vermeer UK, we know that the right equipment and proper planning are the keys to a successful HDD project. If you need guidance on choosing the best horizontal directional drill for your job or want advice on best practices, get in touch—we’re here to help!
