Advantages (Statnamic Bored Piles in Four Season Hotel, Ampang)

• Accuracy and improved safety: Do not require reaction beams or anchor piles (can be very costly to install)

• High Test Load Capacity: High load more than 220MN is possible to be applied (where no other static load test can)

• Reduced Work Area: Required work area (overhead and laterally) is greatly reduced.

• Economy: more economical as loads increase.

Advantages (Statnamic Bored Piles in Four Season Hotel, Ampang)

• Rock sockets: High Loads test can be applied directly on deeply rock or soil formations without load shedding in overlaying soils. (eliminates the need for de-bonding techniques)

• Shear/end bearing component: Separate test piles into 2 or 3 piles section, thus automatically measuring reactions for each of the components.

• Static creep effect: A static MLT and uses automativ data acquisition techniques and load maintenance for accurate, efficient data processing & creep measurement.

• Performance: Its subsequent performance will be similar to non-tested production piles due to lower amount of generated residual stresses in the piles.

CONCLUSION• Ampang areas are made of KL limestone. • LRT tunnel is directly under the building• Building within the development is more than 5

storey.SO

• Fugro Loadtest company carried out 2 full scale multi level O-cell bi-directional load test at the site.

• 2 trial piles under 61m were excavated for 1.5m and 1.8m of each diameter.

CONCLUSION

• The 2 piles provided with 22Mn and 27MN capacity with total gross load potentially 66MN and 81MN.

• By using statnamic bored pile test, the piling work was successful.
