Piling at Mayflower (IV)

Piling works at the Mayflower Station are now about 60% completed. The third traffic diversion along Avenue 4 was implemented earlier this month. The realigned road to the east now allow for piling to be done on the west side of the station box. The diversion is envisaged to last for 3 months. Grouting is taking place on the south side of the station as well.

Lentor Excavation

Excavation works have commenced on the north face of the station box. The outline of the launch shaft at the south end of the station is evident too, and we can expect excavation of the shaft to commence by the third quarter of this year. The linkway to the Calrose entrance seems to have completed excavation to the formation level where 3 layers of struts have been installed.

D-walling works continue at the 5XO crossover site along Ang Mo Kio Avenue 4.

Tagore - TBM Assembles

The first NFM TBM for the T208 project has begun assembly works within the launch shaft. The TBM will be executing an initial drive on the Woodlands bound tunnel towards the retrieval shaft at Lentor. As of Monday, the main shields and backup gantries have been lowered while the cutterhead remains on the surface of the shaft. The gantry crane has been assembled as well. Tunnelling works should commence in a month's time.

Piling across the Tagore C&C have completed and the first layer of strut have been installed across the entire span of the structure.
