Today’s post is about a job I did at the start of January – the world’s premier maker of tunnel-boring machines, Herrenknecht (there are actually quite a surprising number) hired me to document the operation and breakthrough of their first variable-density boring machine*, which happened to be at work underneath Kuala Lumpur as part of the greater Klang Valley subway/ mass transit project.

I was hired to document some of the underground work.
