Horizontal directional drilling (HDD) is a fantastic method for pipeline installation: it’s trenchless and non-invasive, with minimal impacts on the surrounding environment and community. One common question is, how accurate can a typical HDD pipeline installation be? In this article, we take a look at the levels of accuracy in HDD and what factors can impact upon HDD accuracy. What [...]
In this article we explore some of the most frequently asked questions and debunk common myths about horizontal directional drilling (HDD). We’ll discuss the benefits it provides when assessed against other pipe installation methods, and focus on the environmental upside, flexibility of design and how the technology supports construction in congested, urban, industrial and sensitive environments. Do I need to [...]
An increased demand for transparency and accountability in underground pipeline and conduit installations leaves organisations with a lot of boxes to tick. These days, it’s no longer enough for contractors to simply prioritise speed in their installation works; they also need to deploy sustainable methods. When searching for sustainable construction methods, it’s hard to look past horizontal directional drilling (HDD) [...]
Ask An Expert – How new versatile equipment is reducing risks to project delivery in microtunnelling
Microtunnelling projects often encounter a variety of complex challenges that can prove costly and push out project delivery timelines. However, contractors with versatile equipment can easily adjust to unexpected issues – by changing drilling heads, and being able to install a wide range of pipe materials and diameters – to ensure a project is delivered on time and on budget. [...]
By Stuart Harrison, Managing Director, Edge Underground As new technologies and innovations emerge in the microtunnelling industry, contractors’ capabilities to meet some of the industry’s toughest challenges continue to grow. For example, very hard rock used to result in most contractors turning down projects or stopping a job part way through when they unexpectedly hit these conditions. This is because [...]
It goes without saying that safety is a key concern on any construction site, and lots of work goes into mitigating safety risks and ensuring workers get back home safely at the end of the day. However, not all construction methods are equal in terms of safety, with some methods and machines designed to be inherently safer than others, and [...]
