Entering adulthood for many of a certain generation, particularly in the US, has been marked by momentous and somber events. Specifically 9/11 and the Lehman Brothers crash, which we couldn’t control but yet that shaped the way we established our careers and lives. Tue, 24 Dec 2019 12:09:27 GMT Choice of method http://www.tunnelsonline.info/blog/choice-of-method http://www.tunnelsonline.info/blog/choice-of-method One of the important things to remember about science is that it is always refining. While a field advances, improved data collection and the interpretation of studies brings the model we base our understanding on closer to reality. Mon, 23 Dec 2019 10:36:42 GMT Keeping safe http://www.tunnelsonline.info/blog/keeping-safe http://www.tunnelsonline.info/blog/keeping-safe In this issue we have a fire protection angle. You will find several articles covering an incident in Gdansk, variable frequency drives, the impact of fire events on tunnel linings and a piece on the latest health and safety thinking in this area.

A drive time radio host sharing the traffic report will refer to a surface-level enclosed road as a tunnel, or a pedestrian walkway in a culvert, or even an eight lane overpass. When I started working with Tunnels & Tunnelling the general guidelines for covering a project were, at least a kilometer long, and at least eight feet in diameter. The specific numbers aren’t as important, though, as what they signify—the need to excavate without disrupting the surface.

Obvious technological advancements, mergers and retirements aside, many times they are right. Fri, 27 Sep 2019 06:56:00 GMT HS2 under review http://www.tunnelsonline.info/blog/hs2-under-review http://www.tunnelsonline.info/blog/hs2-under-review It is understood that HS2 is at the starting blocks and ready to go. The visible evidence of this can be seen across the county, with major demolition and enabling works around Euston and along the route. The long term effects on spreading wealth northwards can also be seen with development being undertaken in Birmingham and Manchester.

The ITA Committee for Technology (ITAtech was particularly prolific.

It always seems to have a megaproject underway or in the pipeline.

The plan was to show how engineering and innovation meet archaeology, architecture and art. The beauty of Naples is not only above ground, but it is a cradle of underground works, which unveils a network of Greek and Roman tunnels and underground structures dating to the fourth century BC.
