a) Bored Pile

i) 2.0m dia. Bored Pile for Cable-Stayed Bridge Easily adapted to the various load and soil

requirements due to large variety in dia. and construction techniques

Enable the immediate in-situ evaluation of drilled soil layers to revise foundation length due to changed soil

conditions Achieved required capacity of 25 Meganewton (MN) at

120m depth (8m socketed into bedrock)

ii) 1.5m dia. Bored Pile for P283 – P292 80 nos of piles installed at average 85m depth.

4 nos of piles per pilecap. This section contains huge amount of mud and seabed

is exposed during low tide while the water level is just about 1m during high tide. Therefore, it is not

practical to use spun piles as huge amount of mud need to be dredged prior to installation works using

barge. As a solution, Bored Pile design is adopted which was

installed via temporary platform.

Advantages of different types of foundation

Bridge Optimization



b) 1.5m dia. Steel pile for approach bridge Have high load-carrying capacity for a

given weight of pile, which can reduce nos of piles per pilecap.

Driven to 80m length and cause little ground displacement

Easy to splice 6 – 8 nos of pile per pilecap.

c) 1m dia. Spun pile for low-level bridge Prefabrication allows 65m length with no

joint Efficient mass to strength ratio Piles can withstand high tension forces 10 – 12 piles per pilecap.

• The pier are cast in one complete operation using reusable steel formwork

Substructure at the Approach Span – Pilecap, Columns and Crossheads

Bridge Optimization



• The precast segmental box girder is designed as a continuous single twin box of 14.08m width, 4.0m length and 3.20m depth structure with match cast joints, multiple shear keys and prestressing tendons.

• The design has been highly optimized to minimize weight such that it does not require special heavy lifting equipment. Segments weight between 69 to 100 ton.

• Hybrid pre-stressing encompassing both external and internal prestressing for design economy.

• The design of the segments is identical which allows the same formwork to be repeatedly used.

• The depth is maintained constant to present aesthetically consistent soffit line.

Superstructure at the Approach Span – Segmental Box Girder

Bridge Optimization



• PERI formwork system is used for the construction of pylon and piers which are more than 8m height.

• It is a self-climbing formwork that once set up as a desired-shaped wall to be built, it

ascends continually to the height of the structure.

• Each lift will be 4m ~ 5m height • Working platform will be provided at the top of the formwork system • PERI Formwork system

provides high speed of erection (works’ execution speed increases) and as a result, rapid completion of the project

• There is no need to dismantling or re-assembling for every lift.

Stay Cables

The stay cable will be provided with protection against corrosion by means of 3 barriers: i) The first barrier is hot dip galvanising that covers the full length of the individual steel

wires. ii) The second barrier (internal barrier) consists of High Density Polyethylene (HDPE)

sheaths around the individual strands and that the intermediate medium fills the space between the individual sheath and the galvanized strand.

iii) The third barrier (external barrier) is the outer casing which consist of HDPE sheath around the group of strands.

The stay cables consists of the Parallel Strand System (PSS) made up of parallel individually polyethylene coated seven-wire strands, placed inside an external polyethylene stay pipe.

Overview Fisheries Industry in Penang There are 17 fishing villages on the island and 14

fishing landing point on the main land. In 2007, marine fisheries catch in Penang

amounted to 37,774 tonnes worth RM 218.9 million.

The industry provides livelihood to nearly 3,193 fulltime fishermen.

vi. Habitat Creation

Research by Lund University in Sweden has discovered that the Oresund Bridge connecting Denmark and Sweden has improved the Marine Environment in 10 years since it was built.

In the Second Penang Bridge, aquatic life such as algae and

fishes are found abundantly around the newly driven piles.

They become food for fish like the Longfin Bannerfish (Heniochus acumiratus), Rock Grouper (Epinephelus fasciatomaculosus) and White Cheeked Monocle Bream (Scolopsis vosmeri) and the local “udang lipan” (Stomatopod Crustacean).

According to Fanli’s 7th Quarter Monitoring Report, it shows that in terms of seabed productivity, highest macrobenthos (collection of organisms living in sea) densities were recorded during the study as compared to the previous monitoring events (Quarters 1st to 6th). This signifies that the study area is still highly productive. It has also benefited the fishermen.

It is evident that the construction of Second Penang Bridge

does not affect the marine environment of the surrounding area.




o JKSB has issued ex-gratia payment amounting to RM 6.685 million to 3,011 fishermen, cockles breeders and aqua breeders on 24 October 2011 as part of the settlement to their claim of being affected by the construction of the Second Penang Bridge.
