- Yen So Wastewater Treatment Plant and Related Works, Hanoi, Vietnam
The construction of the Yen So STP commenced on 1 January
2009 and was successfully commissioned and handed over to
Hanoi People’s Committee in April 2013 with a contract sum of
USD 288 million. The project was undertaken on a “Build and
Transfer” basis.
Some of the major components of the Project are as follows:
• Two River Intake facilities including debris removal and radial
river gate control at Kim Nguu and Set River to convey raw
sewage/drainage water into the main inlet pump station.
Yen So Wastewater Treatment Plant (WWTP) and Related Works
Project is a good success story of an innovative engineering
solution in transforming an existing 146 hectare derelict public
park into a modern recreational park with high development
potential while providing a major environmental infrastructure
works that benefits more than 40% of the Hanoi city population.
The main objectives of the project were:
1) To provide an immediate wastewater treatment facilities to
more than 40% of the Hanoi raw sewage which eventually
finds its way into the two existing urban lined canals which
serve as a open sewer.
2) To construct a WWTP (using the latest Sequential Batch
Reactor technology ) with a capacity of 200,000 m3 /day.
3) To cleanse and rejuvenate the 5 existing lakes from their
sewage-contaminated state into a pristine, refreshed and
sustainable environment.
4) To provide an efficient and reliable wastewater treatment
facility to serve residents in the eastern part of the city which
can be sustainably operated and maintained.
5) To enable its citizens access to proper sanitation where
sewage is treated and disposed appropriately and to promote
health and better living standards.
6) To provide rubbish collection system at Yen So Lake to prevent
influx of rubbish into the Yen So Lakes during heavy storm
event.
7) To reuse the treated water for replenishing the Yen So Lakes
and downstream irrigation purpose.
8) To improve the agricultural and industrial livelihood of the
people downstream of the Wastewater Treatment Plant.
The WWTP was also designed with fully automated facilities,
operated via a computer controlled SCADA system to
ensure a user-friendly and efficient operating and
maintenance environment.
With a well-developed WWTP and river diversion
system in place, this project has given the people of
Hanoi access to proper sanitation, a crucial factor for
the revival and enhancement of the highly polluted
environment in which they live.

PERUNDING FAISAL, ABRAHAM DAN AUGUSTIN SDN BHD
- City Square Johor Bahru, Addition and Alteration
Johor Bahru City Square stands out as a central landmark in Johor
Bahru. It was successfully completed during the 1998 financial
crisis when several other projects in Johor Bahru were and still
abandoned.
With its more than 200 retailers, it offers a host of fashion,
entertainment and restaurants. Well known brands for Ladies’
and mens’ fashion have taken up space in City Square. The
cinemas are particularly important to shift workers returning from
Singapore in the late evening for entertainment and time to wind
down. The 14 screens affords a wide choice of viewing.
The direct link bridge connection from the CIQ provides a steady
flow of visitors.
The Addition and Alteration to City Square was a live project
where work was being carried out 18 hours a day while the
complex was open to the public. Public safety took precedence
over everything else. Approximately 1,400tons of structural steel
was used in the construction. Built up area exceeded 20,000sq.
At an early stage Perunding FAISAL, ABRAHAM dan AUGUSTIN
sdn bhd proposed that construction in structural steel be adopted
to overcome several site constraints:• Limited capacity of tower cranes for lifting
• Reducing wet works to a minimum
• Reducing weight of structure
• Minimising the number of columns to be strengthened
• Adopting designs that could accommodate architectural
requirements.
The significant reduction of thickness of floor slabs translated
directly into weight reduction. The thickness of floor slab was
100mm compared with the equivalent of 250mm for a RC
structure. A 40% reduction in weight.
The use of dry wall for the cinemas was a milestone built upon
earlier experience.
Deflection of Steel framed structures is greater than the typical
reinforced concrete structures that are commonly encountered.
The designer has to ensure that the member sizes chosen
made composite with the in-situ topping is outside the natural
frequency commonly encountered by pedestrian traffic in a mall.
The natural frequency of beam and slab has to be greater than
4 Hertz.
Another consideration when designing in steel is to use standard
size bolts for greater economy.
Columns were encased in concrete to reduce vibrations when far
field earthquakes are felt in Johor Bahru.
The primary protection for beams was vermiculite. The deck slab
permanent form-work which acts compositely with concrete was
provided with additional steel reinforcement at every through.
Cinema walls using a composite plaster board wall has to satisfy
two requirements namely sound and fire resistance. Generally if
sound insulation is achieved fire resistance is also achieved. Sound
proofing is necessary to avoid lobby noise to infiltrate cinema
halls. It is also necessary to prevent sound from adjacent cinemas
to infiltrate cinema to cinema. When cinemas are located on
rooftops, sounds generated by weather such as thunder or very
heavy rainfall must be prevented to enter cinema halls via the
roof.
Two layers of 13mm fire rated plaster board on either side of a
wall separated by a cavity will give 2 hours fire rating. The lowest
class of walls required 5 layers of plaster board in total. Hence the
fire rating was greater than 2 hours.
The additional cinemas in city square have 204m of walls, a
staggering 794 tons in load reduction before taking into account
of time saved.
The adoption of dry wall construction for cinemas was a milestone
event with significant weight, cost and time savings.
This was first conceived for the first addition of 5 cinemas to City
Square at Podium 1, Level 7 in 2005.
The addition and alteration could not have been completed in 24
months if constructed using conventional RC.
At the new roof top, a vertical green wall was constructed to
create an oasis of calm to complement the reflective pool. To
ensure that the plantings could be well maintained, a movable
“library” ladder was designed that could be moved by a single
person. Without routine and easy maintenance the vertical green
wall will wither and die.
Construction of atrium, reflective and other curved architectural
elements dispels the notion that steel is not “flexible”.

- Wharf 8A at Northport, Port Klang, Selangor
The project involved development of a multipurpose wharf
(Wharf 8A) and associated facilities at Container Terminal 4 (CT4)
as an extension to existing Wharf 8 at Northport, Port Klang,
Selangor Darul Ehsan.
The new wharf and approach bridges constructed were with the
following dimensions:
Wharf Deck : 350m length x 96.56m width at the widest
point
Approach Bridge No. 1 : 198m length x 20m width
Approach Bridge No. 2 : 187m length x 20m width
Height of Wharf Deck above seabed : Approximately 22m
The Client has specified the following key Project requirements:• Creating a new wharf equipped with four (4) super post
Panamax twin lift quay cranes commonly deployed in modern
port.
• Creating a new wharf with structural capacity that is sufficient
for the handling of Emma Maersk of 219,000 Displacement
Tonnage (DT) and an overall length of about 400m.
• As the new wharf is located at the confluence of Selat Klang
Selatan and Selat Lumut, the Client requires the navigation
safety to be studied with real-time navigation simulator
to ensure that the safe manoeuvring of ship berthing and
unberthing can be achieved at the new Wharf.
• The relocation of existing facilities for tug boats and service
boat and shifting of power supply from the old to new
substation without interrupting the port operation.
One of the challenges faced was the extra safety precaution that
has to be taken during demolition, piling and deck construction
since the construction of new Wharf 8A is adjoining an old wharf
structure that has reached its design life with the sensitive silt
mount developed underneath and behind the existing Wharf 8.
The silt mount from underneath the existing Wharf 8 were to
be removed without inducing instability of the existing structure.
The discovery of an unexpected heavy sunken object (within the
new berthing area) caused hinderance to progress of the project
and immediate measures had to be taken to remove the object
using a heavy lifting crane barge.
The main design challenge is for the wharf reinforced concrete
structures to be designed for very heavy wheel loads from quay
crane and the berthing load from one of the biggest container
vessels and consideration must be taken of the constraint in
structure depth due to high water tide level and requirement to
match the existing deck finished platform level and to provide
deep service trench.
Despite the challenges faced the project team managed to
satisfactorily meet the Client requirements. The new wharf with
structural capacity that is sufficient for the handling of Emma
Maersk of 219,000 Displacement Tonnage (DT) and an overall
length of about 400m equipped with four (4) super post Panamax
twin lift quay cranes was completed within the allocated budget.
The safe manoeuvring requirement of ships berthing at and
unberthing from Wharf 8A has been satisfactorily achieved.
All these together with relocation of existing facilities for tug
boats and service boat and shifting of power supply from the
old to new substation was done without interrupting the port
operation.
Apart from the above the impact on the community and industry
had been positive.
The project had not only created a new high capacity wharf for
import and export of trade but also provide employment and
skills development for workers during construction.
The engagement of heavy equipment and procurement of
building materials contribute to the construction industry.

- District Cooling Plant at Lot 4U2 (Plot 12289), Phase 1,
Precint 4, Putrajaya
The intention of the client, Gas District Cooling (Putrajaya) Sdn
Bhd (GDC) was to establish a plant to cater to the increasing
cooling demand requirement of Core Island of Putrajaya by about
10,000 RT. GDC had the intention to build and conceptualised
Phase 1 of Plant 4 as primarily a Thermal Energy Storage (TES)
facility rather than an outright conventional Chilled Water (CHW)
Plant with Chillers.
This is a collaborative effort between the Contractor, Suncon
Construction Sdn Bhd and the design team comprising AD
Consultants (M) Sdn Bhd (ADC) and EDP Consulting Group
Sdn Bhd (EDP). ADC and EDP worked together to provide an
alternative design bid to the Client GDC. It was based on the
alternative designs that included the reengineering the Structural
and Mechanical design that produce a winning bid.
ADC put together a TES Water Diffuser System that ensures
efficient thermal stratification of the cold chilled water and the
warm return water in the Thermal Energy Storage Tank. ADC’s
challenge was to achieve guaranteed capacity with minimum
capacity at optimum overall cost. ADC met the challenge by
making the mathematics meet the reality.
Knowing that the pumps constitute the largest power
consumption, ADC improved plant efficiency by careful equipment
selection, matching them with pipe and system design. The end
result was a plant that looked efficiently laid out, operationally
efficient and coupled with a control system that gave operational
stability and efficient energy consumption.
EDP’s challenge was to look at a tank design that would be cost
effective and constructible for a tank size of that magnitude.
Eventually, EDP proposed a post tensioned concrete tank (as
opposed to a RC tank that was in the conforming design bid).
The post tensioned concrete tank would firstly be effective in
providing a degree of thermal insulation, thus reducing cost of
insulation. In addition, the design of the post tensioning was to
utilise the pre-compression provided by the tensioned cable hoops
to resist the large hydrostatic forces imposed by the stored water.
The tank size measure 33.7m high with an internal diameter
of 45.5m. The design made the tank more constructible with
a uniform wall thickness that allow for quick turnaround time
for each cast of concrete. Steel reinforcement was significantly
reduced and replaced with lesser quantities of 15.2 mm diameter
ASTM A416 strands. From an engineering point of view, this is
the arguably the largest post tension chilled water tank in the
country. It demonstrated the effective use of post tensioning for
large storage tank. From a sustainable point of view, there was
less concrete use in this type of construction thereby reducing its
carbon footprint.
The plant is significant in many ways mainly because of its size. It
is possibly one of the biggest, if not the biggest Thermal Energy
Chilled Water Storage Tank in the world. It is also significant
in Engineering terms because it has been be conceptualised
and designed very much jointly between the Structural and
Mechanical Engineers, to optimise the design so as to achieve the
cost that won the bid.
This project when completed is to provide chilled water for cooling
in the Core Island of Putrajaya. It is an energy efficient system
that in this world where climate change is of great concern, both
nationally and globally, this engineering effort claims to meet that
challenge.
