Step 2 - Excavation - Preparing the foundations

Preparing the foundations...Digging a hole....

In the last step we decided to build a raft foundation, a big "raft" of concrete that is going to support the building, the first step to this is to dig out the existing soil...

Part of this building is an extension of the current basement carpark which is semi - underground (at the very front it is a ground level).

The site excavation size is about 67m x 81m with the depth ranges from 2.55m to 5.95m ( at the tent plaza end)

 This means we need to excavate about 16500 m3 of earth to get down to the start of the level of the foundations.

Each big earth moving truck that you see in Singapore can carry between 6 - 9 m3 of earth, depending on how well the earth is compacted when it is dropped in by the excavator.

So this means we need to remove around 2532 individual truck loads of soil from the site.......

Our soil goes to an earth dumping ground at Marina South and might be used for reclaiming more land around Singapore..More information on earth dumping in Singapore




Once the soil is removed and we have got to the final level that will form the foundations, we then compact the ground with 10,000 Kg vibrating roller. You can feel everything shake when this is working...
