Bored piles are used mostly for large commercial and industrial

developments and transport infrastructure projects.

- Able to support very high load capacity

- Low noise and vibration

- Able to core into hard rock

re

For conventional bottom-up construction, excavation

is firstly carried out through to designed depth. Floor

slabs are constructed sequentially from lowest level

of basement.

Top-down construction method is often used for

large-scale projects with limited construction time in

congested areas. Structure is constructed downwards

from ground level.

Top-down construction method enables faster construction progress…

COMPETITIVE ADVANTAGES

Strengths

26

Page 27: Macquarie ASEAN Conference 2018...Kuala Lumpur that involved the partial top-down construction method Received first bored piling project for 2 blocks of 20-storey condominium in Petaling

Vast experience across wide-ranging projects from key infrastructure to high-end residential and commercial property developments…

• Entails boring a hole into soil or rock to the required depth and

placing reinforcement and concrete into the bored hole.

• Supports higher vertical column loads; widely used for high-rise

buildings, bridge piers, etc.

• Reliable and economical solution for adverse ground conditions,

especially limestone bedrock areas.

Bored Piles

Driven Piles

• Uses pre-manufactured/precast piles which are driven into the

ground by hydraulic hammers

• Conventional method for medium rise buildings and structures.

Jack-in-Piles

• Involves pre-manufactured/precast piles being jacked into the

ground by exerting large force using hydraulic or mechanical

jack-in machine.

• Creates lesser vibrations and noise vs driven piles; suited for

densely-populated areas

Piling Solutions

BUSINESS ACTIVITY: Piling solutions27

Superior technical capabilities and management in foundation services… drawing on extensive experience in both piling and earthworks activities

• Bored piles constructed at close spacing, incorporated as

permanent structure for basement walls.

• Large diameter contiguous bored piles can be constructed to

enable a longer cantilever structure for ease of unobstructed

excavation works.

Continuous

bored pile

Diaphragm

walls

• Rectangular reinforced concrete walls, incorporated as

permanent structure for basement walls.

• Can be installed in close proximity to existing building

structure, rendering it suitable for congested areas particularly

for deep basements.

Steel sheet

piled walls

• Commonly a temporary retaining wall, or an alternative to

diaphragm walls.

• Also used in remediation of contaminated soils, major

components in infrastructure construction (e.g. bridges, dams,

port facilities) and in supporting excavation works.

Earth retaining systems among the Group’s complementary services…

As excavation works go deeper, a lateral support system is required to prevent excessive

movements in the earth retaining systems.

This is to prevent the sinking of ground surface surrounding the excavation pit, which may cause

the collapse of the earth retaining system.

Ground

Anchors

• Constructed by drilling holes through the soil according to the

required depth. The holes are filed with cement ground.

• After the cement ground has gained strength, the steel strands

are stressed against an anchor block, which is constructed along

the retaining system.

Steel

strutting

• Steel H sections are used to brace the excavation pit by

extending over the excavation. The steel section will be

supported by vertical H beams or king post (central vertical

post).

• Multiple layers of steel strut are installed for deep excavation.

Able to undertake top-down and bottom-up construction works for substructure and basement construction works…

Substructure & Basement Construction Works

Thick concrete slab constructed

above a group of installed piles

and acts as support to column

that supports superstructure

Pile Caps

Reinforced concrete floor where

its thickness depends on the load

it will bear

Basement Slabs

Conventional Construction

(Bottom-Up) Method

• Piles are exposed and sliced off before the pile cap

is casted. Casting is performed on the lowest

basement, column and subsequent basement slab in

this order.

• Work sequence starts from the lowest slab before

progressing upwards

Top-Down

Construction

• Structure is constructed downwards from ground

level; and is preferable in congested areas with

shorter construction periods.

• Enables utilization of upper floor slab as lateral

support to the retaining system, omitting the

construction of ground anchors or steel struts.

Substructure works consist of pile cap, basement floors and columns up to the ground floor level.
