For the most recent issue of Underground Utilities I was struggling to find a strong cover story. We knew that we would be looking at Horizontal Directional Drilling (HDD) but the theory piece and market overview that I had written was not going to make an exciting cover. Luckily VolkerWessels UK came to my rescue with the suggestion that I hotfooted it over to the Netherlands to see their sister company Visser &Smit Hanab deliver a new gas main for local energy firm Gasunie. Not only were they undertaking HDD they were undertaking it in several locations giving me a wealth of case studies to choose from. Most exciting had to be the banana bore which the team explained required a steep angle of inclination to get the 48inch steel pipe under canal sheet piles. Read more here: Autumn UU
As always I am very grateful to Tim, Jurre, Jeff, Joey, William and everyone else onsite that helped in the research.
I am now on the lookout for auger boring, rock drilling and vacuum excavation case studies for the next issue so get in touch if you have exciting projects to talk about.
