- 2. Column Pile Cap Piles orother type of deep foundations Thick concrete mat + concrete piles = pile cap Tang Lam Yu 0324966 . Lai Eugene 0324075 . Goh Pei Jeng 0329735 . Benjamin Ng 0324541 . Yap Choe Hoong 0323161
- 3. To distribute a singleload equally over the pile group and thus over a greater area of bearing potential. To laterally stabilize individual piles thus increasing overall stability of the group. To provide the necessary combined resistance to stress set up by the super stucture and ground movement To transmit the building loads to the foundations and the ground soil layers whether these loads vertical or inclined. To allow column or superstructure to reside on a stable and solid core foundation instead of residing directly on ground. Tang Lam Yu 0324966 . Lai Eugene 0324075 . Goh Pei Jeng 0329735 .
