Well, I originally went to Hong Kong to join a friend of mine (experienced construction worker) as a way of being closer to the Phils where my family were living.
I had no previous construction experience and was over 40 years of age at the time...but I'm up for anything.
I found a job driving the big dump trucks on the new airport first, and did about a year on that project.
Back to the Phils for a long holiday, and then to the tunnel project, initially because I was a qualified 'plant op' by then. I finished up doing a variety of hard physical work there as well as operating plant and the train in the tunnel, and was also promoted to working foreman...about a year in all.
Back to the Phils with the famly, and then joined a suspension bridge project where I helped lay the track bed for the MRT railway through the inside of the bridge. That lasted about 6 months, during which time I brought the family over to Hong Kong, in preparation for bringing them to the UK before the handover of HK to the Chinese in 1997. I went back there again after we found a place in England and the kids were at school here.
