The Sail @ Marina Bay

 

4 Use of a strut-free multi-cellular diaphragm wall (“peanut”) - a first in Singapore - reduced ground movement due to its rigidity and reduced construction time by three months.  
  
5 Use of high strength Grade 80 concrete - another first in Singapore. This reduced perimeter column sizes and differential vertical movements between walls and columns.
6 Developed in conjunction with the contractor, a comprehensive instrumentation regime was devised for close monitoring of ground, MRT tunnels, retaining walls and tower movements to ensure full safety during construction.
