Jason's Hong Kong Experience (so far) It was our second day in the tunnel... The giant piece of equipment you see in the middle picture is the tunnel boring machine that they used to drill the train tunnel. It is about 25 feet in diameter and now they need to get it out of the tunnel. Needless to say, it was a busy day at the site. Access to the bottom of the tunnel involves some rather crude scaffolding and spaces where you almost need to crawl. The top photo shows all the concrete trucks that were driving in and out making it difficult for us to move our
equipment to the site. The Studio Theatre is what we are all concerned about for this project. They have performances there and if the train causes noise and vibration (since the tunnel is about 100 feet away) the audience would be disturbed during the performances. It needs to be VERY quiet... Our big day testing is actually in the middle of the night tonight which puts me back onto USA time... not sure how that will go, but I am expecting to be tired. Can't wait for the work to be over so I can start enjoying HK more with Laura. Lots of plans for the rest of the trip once I am done with the testing!

Jason,
Fascinating! It appears that the boring machine you pictured is partially disassembled. Is it necessary to dismantle the machine in order to get it out of the tunnel bore? You say you must do your testing at night, which puts you back on USA time; does that mean you have to coordinate your efforts with a part of your team in the US as you do your testing? Lastly, how can you determine the potential penetration of sound from trains in the tunnel if the tunnel is not yet completed?
Regards,
Bob
