OLD AND THE NEW
A new year, the chance to put aside or perhaps turn away from what is old. Not much chance of that for
engineers in an industry charged with building and maintaining the heavy, fixed, durable infrastructure needed by society. Refurbishment and repairs are needed, and to varying degrees and quantities. In this issue we hear of
considerations for the refurbishment of the ventilation system in a Swiss road tunnel. There are also projects involving such works in North America, which we provide updates on, as well as a variety of new project tunnelling works, underway and planned. New tunnel works are the dominant
activity in Latin America, which we also spotlight, but even moreso across Asia - where North-East Asia (led by China, and much activity in Japan) is now the leading region in the world for tunnel-related infrastructure projects, according to the latest analysis from T&TI’s sister business unit in GlobalData plc. Most of the new project pipeline
is dominated by Transport sector projects, and of those the leader
is the Rail & Metro sub-sector - although Roads come close in some countries. The data look at major civil
engineering projects for the most part. But civils, and tunnelling, includes so much else - the undramatic works of refurbishment and repairs, as noted; but also numerous jobs in small diameters, for utilities and other needs, and also for new tunnels as well as those needed to replace older tubes, or, again, to maintain and upgrade what exists. Which has another echo of
the old, and perhaps ageless, considerations. For all excavations there is the argued case for ground investigation - which happens to greater or lesser degree than may be desired for all sort of reasons. We are pleased, therefore, to share a feature article that discusses ground investigation for proposed projects with small diameter tunnels, and the benefits to be won, as with the larger. GI, it never gets old.
