Piling at ULS

Coring and piling works have commenced at the Upper Thomson Launch Shaft (ULS) over the past month. At the site, 2 BG40s rigs and a mobile crane have progressively arrived while 4 pairs of bentonite silos have been erected. The permanent-temporary walkway pavements and site access around the launch shaft have also been fully done up by Sato Kogyo. The launch shaft is on track to be done up by the middle of next year and subsequently see its first Slurry TBM being launched out towards the end of 2015.

The photos consolidated in this update were taken on Oct 27, Nov 11 and Nov 26.
