TBM C was relaunched in July. The removal of the temporary rings and reaction frame at the lauch shaft last month completes the TBM's conversion to its main drive. TBM B is now halfway through its tunnel drive to Springleaf and under the Seletar Expressway. The concourse slab at Tagore has been cast.
