Gamuda Berhad (29579-T)
Annual Report 2013
Strutting and heavy excavation for station box are well advanced
at the Pasar Rakyat MRT station. Also seen in the picture
(background) is the Upper Inai Launch Shaft, where one unit of
VD TBM will tunnel towards the Bukit Bintang MRT station.
To safeguard the continuous integrity of the National Museum building, located
just next to the KL Sentral MRT station work site, extensive monitoring of ground
movements caused by construction works was carried out.
Workers are working hard to sustain the tunnelling momentum by installing
temporary rail tracks (at the centre of the picture) to facilitate the transfer of
tunnel ring segments into and excavated materials out from the tunnel at the
Semantan Portal.
To support the fast-paced Kenny Hill formation tunnelling at the Semantan Portal, fresh air needs
to be channelled into the tunnels 24/7 via ventilation ducts, while tunnel ring segments are
systematically stacked waiting to be transported into the tunnels for installation.
