The document discusses the foundation works for the Marina Bay Financial Center Phase 2 commercial tower project in Singapore. It involved constructing 338 bored piles, 426 meters of 1,000mm thick diaphragm walls, and 3,965 jet grout points to support the tower. The foundation works had to be carefully coordinated with several adjacent construction projects and complied with strict movement criteria due to nearby MRT tunnels. Some of the major challenges included excavating next to an existing tower while installing jet grout piles, coordinating with a tunnel linkage to the new tower, and ensuring no impact to preexisting underground structures.

consists of 338 bored piles, 426 m of 1,000mm thick diaphragm walls and 3,965 JGP points. Site works had to
be executed in close liaisons with adjacent contractors for the construction of MBFC Phase 1,Tower 1 and 4,
the DTL1 MRT tunnels and the existing Common Services Tunnel. Construction of the Diaphragm Wall,
Bored piles and Ground Improvement foundation Works were carried out in compliance to the stringent
movement criteria's of the LTA M&W Specifications and the Common Services Tunnels.
The major challenges encountered in MBFC Phase 2 diaphragm wall , ground improvement and bored piling
works includes the following :
 Adjacent Tower 1 construction of deep excavations in conjunction
MBFC Phase 2 with Jet Grouting activities.
 Adjacent Tower 3 construction of MRT tunnel linkage to MBFC Phase 2.
 Encroachment of existing bored piles and sheet Piling works into
MBFC Phase 2.
 Movement criteria and close tunnel monitoring and liaisons with
the adjacent Common Services Tunnel.
 Presence of existing underground old seawalls.
