Abstract
Malaysia is a developing country located in South-East Asia. The demands for high
rise buildings, are high in industry construction. A raft foundation is designed to
support the load applied to it safely. The ability of building to sustain the applied loads
depends on the building’s foundation system. Foundation is an important part of
every building, which interfaces the superstructures to the adjacent soil or rock below
it. Therefore, early thermal cracks have to be well controlled to have a durable
foundation. Thermal movement occurs when the temperature of concrete changes
due to environment changes or heat generated when the cement first hydrates.
Thermal movements due to changes in the ambient temperature are normally not a
problem in concrete structures. It can be controlled by number of movement joints or
isolation membrane. However, the temperature differential between the center and
the surface of the concrete is hard to be controlled by workmanship.

THE CONCEPT
Platinum Park “A World Class Destination"
Platinum Park is an integrated high-end residential and commercial development within the
prestigious Kuala Lumpur City Centre. With seven towers, namely two super condominium
towers, a serviced apartment, a five star hotel and three Grade A office towers and a
“necklace" of niche retail outlets within the development, it is destined to become an iconic
development in Kuala Lumpur. Platinum Park will also feature a 1.5 acre central landscaped
park at the heart of the development.
The first tower, a 50 storey known as “Menara Felda" was sold to FELDA in January 2008. The
substructure is completed and now work has begun on the construction of the super-
structure. Another 50 storey office tower was sold to the NAZA Group of companies whilst
the adjacent 38 storey was sold to another institutional buyer. Substructure works for both
towers have also commenced. The overall Platinum Park development is expected to be
completed in 2018
THE ARCHITECTS
FOSTER + PARTNERS
A one-of-a-kind development like Platinum Park demands a one-of-a-kind architectural
touch. This is where Foster + Partners comes into the picture. Based in London with project
offices worldwide and led by legendary Founder and Chairman Norman Foster, it is one of
the most innovative architectural practices in the world today.
What it brings to Platinum Park is a sustainable approach to architecture and ecology,
something the practice has pioneered through a strikingly wide range of award-winning
work, from urban masterplans, public infrastructure, airports, civic and cultural buildings,
offices and workplaces to private houses and product design.
With over 500 awards for excellence and 92 wins in national and international competitions
since its inception in 1967, rest assured Platinum Park will be an additional proud entry in
the practice’s portfolio and another architectural milestone in the evolution of Kuala
Lumpur.
RSP started out as a small partnership practice in 1956 and has since grown in scope and
scale to become one of the largest and most established practices in Asia. With offices
around the globe and over 900 staff in various fields, the RSP group has established itself as a
leading firm providing multi-disciplinary services.
The company has since successfully completed a number of landmark works in Kuala Lumpur
that go beyond pure fiction to create good “architecture? And Platinum Park will be no
exception to this novel approach, with RSP designing the project to be a “haven within a
city?
And as evidenced with the Menara Felda and Naza Tower, RSP has managed to establish a
unique visual identity to the development and help make Platinum Park one of the most
exciting developments that Malaysia had ever seen.
THE PARK
Amidst the towering high rises and architecturally dramatic skyline of the Kuala Lumpur
central business district, Platinum Park, created by an internationally reknowned team of
architects and landscape architects , will be a unique destination which will balance nature
with community. Located within this bustling metropolis, business, retail, residential and
leisure activities will successfully co-exist within a central park-like setting. Inspired by
contemporary styling , visitors, residents and business professionals will stroll through this
urban oasis and be captivated by its dramatic architecture, its elegant and interactive
gardens and its vast array of integrated community and business events that shall take place
here. Retail venues with outdoor seating, expansive lawn areas, an interactive water show
and walking paths that deliver visual surprises at every turn are just a few of the amenities
planned at Platinum Park.
PLATINUM PARK TO GO GREEN
Platinum Park is to be an environmentally sustainable development that will conform to the
newly launched Malaysia Green Building Index (GBI) .
In conforming to the GBI the development core design will include greater energy
efficiencies, improved Indoor environmental air quality, sustainable site planning &
management, sustainable materials & resources and water efficiency . The three office
towers of the development presently under construction that is the Felda Tower, Naza
Tower and yet-to-be-named 38 storey tower will be among the pioneer recipients of a GBI
rating.
With the buildings of Platinum Park conforming to GBI and blending harmoniously with the
surrounding environment and local climate , this high-end residential and commercial
development is well destined to become an iconic development in Kuala Lumpur.

Problems
Platinum Park Construction Site
The delegation then visited Platinum Park basement construction site for high-rise
buildings. It is located near to the Twin Tower with a total area of about 9.11 hectares.
The development comprises luxury condominiums, exclusive 5-star offices and service
apartments. The construction work consists of five phases. The ground condition in
this area is peat/alluvium and Kenny Hill overlying limestone. The engineer shared with
us the challenges in their design of the foundation works in such ground condition.
Two types of foundation were adopted for the Platinum Park: raft foundation and bored
piles. Raft foundation was adopted when the ground condition consists of a thick layer
of peat. Diaphragm walls or/and reinforced walls were constructed at the periphery of
the area for each Phase. The diaphragm walls are 600mm thick and 13 to 17m deep.
The size of bored pile ranges from 1000mm to 1800mm, with its length varying from
20m to 52 m. The pile testing scheme consists of compression load test, tension load
test, statnamic load test, sonic logging test, low strain dynamic load test, and high
strain dynamic load test. As the site is located in the hub of Kuala Lumpur, the
ground movement due to construction is strictly specified. The allowable movement of
the diaphragm walls is less than 50mm or 0.5% of excavation depth, whichever is less.
Settlement points were installed to monitor the ground movement at the periphery of
the site and strain gauges on the diaphragm walls to monitor the wall movement during
excavation.
According to Chong (2009B), the procedures in bored pile installation have 7 stages has been considered as follows :
1) Pile Location Setting OutSurveyor shall set the pile position. Two (2) reference steel pins has been installed/offset equidistant at not less than 1.0m from the pile position pin as shown in Figure 2.1.
Step 1
a. Set out the position of Bored Piles as per construction drawingsb. Mark the pile position c. Summery the existing ground level at the pile position
Step 2.
a) Mobilize the boring plant 10 the intended bored pile position.
b) Position the centre of aucer exactly above the pile point.
c) Check the verticality of Kelly bar before boring commences.
d) Offset two reference points perpendicular to each other from the pile position
Figure 2.1 : Pile Location Setting Out
Step 3
a) Comment boring at the pile position.b) Check the vertically of drilled hole during boring works.
FIGURE 2.1 : PILE LOCATION SETTING OUT
2) Installation of Temporary Steel Casing
The temporary steel casing has been driven by the vibrator (vibro-hammer)
into the ground with frequent vertically check against two plum bobs placed
orthogonally, or by spirit level if casing length is less than 6.0m. The casing has
been installed into such depth (minimum 1.0m or below the unstable strata)
to prevent collapse of any unstable soils. The casing also assists on aligning
the drilling tools to ensure that the vertically is within the permissible
tolerance. Top of casing shall be at least 500mm above platform level to
prevent the falling hazard into the bored hole as shown in Figure 2.2
Step 4
a) Conserve the stability of Bore Hole during boring work.
b) If the borehole is unstable or collapse insert a temporary casing into the bore
hole.
c) Check the vertically of temporary casing during installation. Used two plums
positioned in perpendicular directions to each other.
d) If the bored holes is still unstable of collapsible, stabilising fund in the form of
water or bentonite may be use to standuse the bored hole.
Figure 2.2 : Installation of Temporary Steel Casing
3) Boring of Pile
Soil augers and bucket have been used to bore out soft to hard soils. When
very hard soils or rock are encountered, rock auger has been used. Core
barrels may also be used to reach the design founding level if required. The
use of chisel has not been permitted. Verticality of bored hole can be assessed
by looking at the position of the Kelly bar relative to the temporary casing.
Bored hole is vertical if the Kelly bar is right in the centre of temporary casing.
During the boring process, bentonite slurry has been introduces into
the borehole as stabilization fluid. Fluid(bentonite slurry) introduced into the
borehole achieves the stabilizing effect by ensuring that the pressure inside
the borehole is greater than the horizontal soil pressure and groundwater
pressure, at all depth. The drilling fluids parameters have been checked for
every pile after de-sanding from samples are to be re-established prior to
commencement of concreting. A submersible and circulation pumping system
has been utilizad for this procedure.
The soil samples has been collected at every 5.0 m intervals and then
stored in plastic bags and indications are clearly marked for further reference.
Upon reaching the design level, the drilling tools have been replaced with a
specially designed flat-bottom bucket of adequate size (cleaning bucket). This
bucket has removed the loose debris or disturbed soils at the base of
borehole. The base cleaning completed when depth measured recorded
stable after a few repeating of cleaning completed when depth has been
carried out by lowering down measuring tape to the bottom of bored hole.
Plumb with sufficient weight has been installed at the end of measuring tape
to ensure it will be able to reach the bottom of bored hole as shown in Figure
2.3.
Step 5
a) Continue boring with an anger or boring bucket depending as shown in (a) & (b).
b) Carry out boring until the design depth is achieved.
c) If hard material is encounted during boring, use rock tools 10 penetrate into the
hard stratum as shown in (c)
Step 6
a) After reaching to depth, clean the base of bored hole with a cleaning bucket.
b) Verify and contain the pile length with client’s representative.
Figure 2.3 : Boring of Pile
4) Installation of Steel Reinforcement Cage
The fabricated reinforcement cage is then lowered into the completed hole.
The cage has been of length, size and reinforcement detail in accordance to the
specifications. The cage has been temporary supported by means of two steel hooks
or wire rope until concreting is completed. Lifting of the fabricated reinforcement
cage has been carried out in such a way to ensure that buckling has not occurred to
cage as shown in figure 2.4.
Step 7
a) Check and ensure the reinforcement and dimensions of case and appropriate
for the intended pile. Ensure that the cage is intact for handling
b) Hoist and transfer the pre-fabricated reinforcement cage into the borehole to
the cut off level.
5) Concreting of Pile
Concreting has been carried out using tremie method. The tremie pile has
been of ID-250mm assembled in 3.0 to 5.0m sections with shorter section near the
top. The tremie has been watertight and extend to 200 to 300mm from the borehole
base. It is topped-off with a conical hopper to receive concrete. Before discharging
any concrete, Styrofoam plug or similar has been placed into the hopper of tremie
pipe in order to ensure a continuous concrete column in the tremie and prevent the
concrete from mixing with the fluid (within tremie pipe). The concrete has been
discharge into the pipe through the conical hopper. Concreting by tremie method has
continued until the concrete level is approximately of minimum 300mm above pile
cut-off level. Higher overcast has been required to allow for concrete slump down
during casing extraction. The tremie has been dismantled and shortened
progressively, but at all times maintaining at least 2.0m embedded within concrete,
the displaced bentonie has been pumped back to the treatment plant. During
concreting, a log is kept of delivery times, volumes and concrete levels. Concrete
cubes are taken to assess the concrete strength as shown in Figure 2.5
Step 8 (Concreting in ‘wet hole’ conditions by tremie method)
a) Lower the tremie pipe to the toe of barehole.
b) Discharge concrete directly from the concrete truck into the hopper.
c) Fill concrete from the bottom of borehole which displaces the sludge as
concrete rised to be top.
Step 9 (Concreting in ‘wet hole’ conditions by tremie method)
a) Withdraw the treme pipe as concrete rises upwards.
b) Ensured that the end of tremie pipe is embedded into the concrete at all time
during concreting
c) When concrete has reached above the cut off level, the tremie pipe is
withdrawn completely.
d) Ensure that sound concrete has reached above the cut off level.
Figure 2.5 Concreting of Pile
6) Backfilling of Hole
The hole has been backfilled with selected bored out sandy material at least 4 hours after
concreting.
7) Extraction of Temporary Casing
Temporary casing has been extracted within 2 hours after concreting has been extracted
using vibrator till the casing is loosened. The casing has been extracted by means of a sling
wire attached to the top of casing as shown in Figure 2.6.
Step 10
a. Extract the temporary casing from the borehole upon completion of
concreting works.
b. Ensure that the temporary casing is extracted vertically.
Figure 2.6 Extraction of Temporary Casing
Type Of Construction Method
Rapid Transit System (RTS) Some of the under ground Rapid Transit System (RTS)
stations are constructed by the “top-down” method. In this method, the under ground
retaining walls are first installed. In most cases, these retaining walls ar e concrete
diaphragm walls.This is followed by excavation to just below the roof slab level of the
under ground structure, with the retaining walls and struts supporting the soil at the
sides.The roof slab is then constructed, providing amassive support across the
excavation. Access openings on the roof slab ar e provided so that works there
after could proceed downwards to the base slab level of the under ground structure.
Upon completion of the base slab, the side walls are constructed and the
intermediate struts are progressively removed. The access openings on the roof slab
are then sealed and the ground is subsequently backfilled and reinstated.
Sequence Top Down Construction
Design Of Raft Foundation
Design Considerations:
If the loads transmitted by the columns in a structure are so heavy or the
allowable soil pressure so small that individual footings would cover more
than about one-half of the area, it may be better to provide a continuous
footing under all columns and walls. Such a footing is called a raft or mat
foundation. Raft foundations are also used to reduce the settlement of
structures located above highly compressible deposits. Since rafts are
usually at some depth in the ground, a large volume of excavation may be
required. If weight of the excavated soil is equal to the weight of the
structure and that of the raft, and the centres of gravity of excavation and
structure coincide, settlement would be negligible. Where complete
compensation is not feasible, a shallower raft may be accepted if the net
increase in loads in small enough to lead to tolerable settlement. A raft
foundation may be rectangular or circular and may be with or without an
open as shown in fig.1 and fig.2.
Fig.1: Solid Raft Slab
Fig.2. Circular Raft Foundation
If the columns are equally spaced and loads are not very heavy, a raft may
be designed as having uniform thickness. The conventional design of such
a raft consists of establishing its dimensions, from which the soil pressure
at various locations beneath the slab may be computed. The raft is divided
into a series of continuous strips centered on the appropriate columns and
rows in both directions as shown in fig.3. The shear and bending moment
diagrams may be drawn using continuous beam analysis or coefficients for
each strip. The depth is selected to satisfy shear requirements.
Fig.3: Raft foundation with strip centered on columns
The steel requirements will vary from strip to strip. This method gives a
conservative design since the interaction of adjacent strip is neglected.
If the columns are equally spaced and their loads are equal, the pressure
on the soil will be uniform, otherwise moments of the loads may be taken
about centre of the base and pressure distribution determined. Since the
equations for this are usually derived for a rigid member and a raft in
general is not a rigid member, the pressure and resulting internal stresses
may be seriously in error if the eccentricity is very large. The weight of the
raft is not considered in the structural design because it is assumed to be
carried directly by the subsoil.
Raft may be ribbed where the column spacing is irregular or for economy
in using a relatively thin slab over most of the area as shown in fig.4.
Alternatively, rafts may be thickened at the column locations for economy
and depth should be made sufficient to resist shear. A ribbed raft
foundation consists of a slab acted upon by upward soil pressure at its
underside and supported by beams from column at its top which balance
the upward pressure with downward column loads. It is a similar to a floor
slab resting on a system of beams and columns. The portion between
beams is designed as a conventional one way or two way slab. If the
beams are deep, they should be designed as deep beams.

The Schedule & Planning
Industrialised Building system
Formwork" means the surface, support and framing used to define the shape of concrete until it is self-supporting. Note This term includes the forms on which the concrete is poured, the supports which withstand the loads imposed by the forms and the concrete, the bracing which may be added to ensure stability, and the footings. When complete the formwork can be known as the formwork assembly. Supports and bracing mentioned above are sometimes known as falsework.
MFE's aluminium formwork system is designed in such a way that it has in-built safety features and also possesses significant environmental advantages over other formwork
materials.
MFE formwork technology is comprised of a total aluminium system that is designed and manufactured to the specific requirements of each project design. It can form all elements of a concrete structure, including architectural features, and is probably the most versatile modern construction system in use which is equally suited to high and low rise construction especially in the residential sector.
The Formwork is specifically designed to allow rapid construction on all types of architectural layouts.Total system forms the complete concrete structureCustom designed to suit project requirementsUnsurpassed construction speedHigh quality finishCost effectivePanels can be re used up to 300 timesErected using unskilled labourEnvironmentally friendlier than other systems
Independence from Scarcity of Skilled Tradesmen
The System eliminates the need for skilled plasterers as noted above, but it also eliminates the need for skilled carpenters and brick layers. Projects have often been seriously delayed because of the unavailability of these skilled trades.
Scaffolding The need to carry the cost of scaffolding for the construction of the structure is eliminated, as the System provides its own work platform brackets, which ascend the building as it being constructed. There is the added advantage that the infrastructure can now proceed in parallel with the building construction, as the contractor has unimpeded access to the base of the building.
Cranage The crane is not required for the movement of the forms up the building as the construction proceeds. Thus the crane is available for concrete and steel placing and other materials movement. The crane is only required for moving the forms down from the top of the completed building.
Structure The System allows consideration of a "load bearing walls" structural design approach. A LBW design will always be more structurally efficient than a traditional "reinforced concrete frame" approach and will give a very much stronger building. It will therefore be less expensive to construct and to provide foundations for. Because the System is modular, it can be fitted to any architectural or structural layout. Thus, the designers can be as creative as they like and yet be confident that advantage can be taken of the system approach to construction. In this regard, the System is quite different to Tunnel Forming or systems based on the use of Flying Forms - both of which require the designers to modify the design the building to suit their particular system.
Reliability Not only does the System give a remarkable construction speed, it gives the speed reliably. We will contractually undertake to complete 6 floors per month (i.e. 6 floors at 4 days per floor, plus approx 6 days to spare for items outside control e.g. crane breakdown, access problems, access for ready mix trucks, etc. etc.) and would be confident of
exceeding that rate. This allows the Developer to plan accurately and with
confidence and streamline his own organization for handover of
apartments or commercial space to Clients.
Overall Financial Advantage
When all of the above are taken into consideration over the construction
period of a suitable project (i.e. one where there are more than about 50
repeats of a typical layout), the overall profit to the Developer can be
increased by a factor of from 10 to 30%. The overall advantage is the cost
and time savings to the developer.
In view of the above, System Formwork has a very competitive state-of-the-
art technology which has gained market acceptance over a relatively short period
of time as evidenced from the major projects completed and new projects
secured to-date. Some of the System's clients are established and reputable
developers and contractors themselves such as C.A. With the revival in the local
construction industry, in particular that of low and low-medium cost houses, as
well as massive demand for speedy social housing development in the countries
in the Asian region and other parts of the world,
SPEED
The in situ construction of all walls and partitions reduces the requirement for follow-on wet trades. The concrete surface finish produced with the MFE aluminium forms allows achievement of a high quality wall finish without the need for expensive plastering.
Door and window openings are formed in position, with a high degree of accuracy. Precision items such as door and window frames can be directly installed on site and minimal re-sizing required.
First fix electrical and mechanical services can be cast in place.
SITE MANAGEMENT
The essence of MFE formwork technology is that it is provides a production line approach in the construction industry by simplifying and streamlining the complex construction process.
Scheduling involves the design and development of the work cycle required to maximize efficiency in the field. The establishment of a daily cycle of work, which when fully coordinated with different trades such as reinforcing steel fixing and mechanical services cerates a highly efficient working schedule, not just for the formwork but for all parallel
trades and building material supply chains.
Experienced MFE site supervisors are sent to site to train the supervisory staff and labour in the proper handling of the equipment and to assist in getting started and establishing the desired work cycle.
This improved co-ordination and construction management enables the equipment to be cycled at optimum speed and ensures that the results in terms of system efficiency and speed of output are outstanding. Speed of construction mainly depends upon economy required and
PERI innovations – the next “must have” systems for the Malaysian
construction industry Developed by Naza TTDI, Platinum Park is set to be the
“jewel in the crown” in Kuala Lumpur’s city centre. Platinum Park, an iconic mixed
integrated development in the Kuala Lumpur City Centre, the city’s prime business
district, is also at the forefront of green development. Main contractor Putra Perdana
is relying on PERI as their partner to pursue their mission.
PERI solutions – At the forefront of innovation and sustainability
When the main contractor Putra Perdana embarks on a project, the emphasis is on
eco-friendliness and sustainability. For the company, this philosophy is apparent
throughout all processes. It is no surprise that Putra Perdana uses PERI formwork
and solutions. Among other advantages, PERI systems can be re-used, thus
reducing the wastage on the site. This active contribution to the preservation of
natural resources is part and parcel of the daily operation at Platinum Park. Putra
Perdana plans ahead, making best use of the PERI systems. Once no longer needed
at one site, they can be used at others sites. Through modifications, the systems
have a long lifespan.
“PERI systems help us to realise the designs of the architects. The formwork already
accommodates the shapes and forms of walls and structures. This is a huge
advantage over other methods. No longer do we have to produce a patchwork of
throw-away wood panels to create the shapes envisioned by architects and
developers”, states Mr. Alexander Lo Tzone Leong, General Manager of Putra
Perdana. According to Leong, PERI systems are at the forefront of innovation, not
only responding to current developments in the industry, but being ahead of the
curve.
RCS Table Lifter from PERI - The “must have” application on modern construction sites
One of those innovations is the RCS Table Lifter. Used for the first time at Platinum
Park, the system is already very popular among Putra Perdana’s staff. Based on the
highly successful RCS series, the table lifter climbs up in unison with the building.
Tables for slabs are being assembled on the ground floor and then lifted up by a
hoist. Tables can now be lifted up in segments, making the preparation of the slab
work faster. According to Mr. Leong, workers claim that they could not imagine
working without the RCS Table Lifter anymore as it makes the process of bringing the
tables into place easier and faster. The Table Lifter immediately established itself as
a “must have” for modern constructions sites.
Systems working synchronised for better results
Besides the RCS Table Lifter, other systems are being deployed at the site to allow a
more efficient workflow. RCS Systems with safety screens are used as well as
column formwork. Also based on the RCS system, the safety screens help providing
a safer working environment. Protected from winds and falls, the system offers peace
of mind when it comes to working high above the ground.
As the RCS Table lifter also speeds up the development of the building, other
systems need to keep up with the increased speed of progress. The PERI Vario
column formwork is the ideal partner for this as it also reduces the time needed for
column production.
Service and support from tender to completion allows constructions to rise more efficient
Through a local support team, PERI is able to work with contractors as early as the
tender stage to provide the best possible solutions. Contractors rely on the expertise
of PERI to respond to the requirements early in the project. Designs can be
customised with quick response times to the proximity of PERI to the market. For
Putra Perdana, the PERI brand stands for reliability. If one needs a replacement part
for formwork, it is needed quick. PERI can respond to such urgent requests as the
company has an extensive network and stocks up vital parts nearby.

Defination BMS
A BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.
Systems linked to a BMS typically represent 40% of a building's energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.
As well as controlling the building's internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.
Building Management Systems have been employed for as long as commercial buildings have existed, whether this be through manpower loading coal into coal fired boilers or opening water pipe valves manually with the use of a handle so to enable heated water to flow through a radiator circuit. However, "BMS" as a phrase, is relatively new, the concept being introduced in the early 1970's (the terms BAS-building automation system, and EMS-energy management system are also used); the phrase has only really existed since the introduction of complex electronic devices that are capable of retaining data for the purposes of managing services such as power, lighting, heating and so on. It was the advent of the "modem", or "modulator-demodulator" which allowed analog signals to be digitized so that they could be communicated over long distances with a high degree of accuracy that spurred the development and deployment of modern BMS's. The Powers 570 was an example of such a system. Developed and marketed by Powers Regulator Company (later purchased by Siemens), it was deployed into the market in May 1970, as the model number suggests.
Before the modern, computer-controlled BMSs came into being, various electromechanical systems were in use to control buildings. Many facilities management offices had panels consisting of manual switches or more commonly, lights showing the status of various items of plant, allowing building maintenance staff
to react if something failed. Some of these systems also include an audible alarm. Advancements in signal communications technology have allowed the migration of early pneumatic and "home run" hard wired systems, to modems communicating on a single twisted pair cable, to ultra fast IP based communication on "broad band" or "fiber optic" cable.
Functions of Building Management Systems
To create a central computer controlled method which has three basic functions:
controlling monitoring
optimizing
the building’s facilities, mechanical and electrical equipments for comfort, safety and efficiency.
A BMS system normally comprises
Power systems Illumination system
Electric power control system
Heating,Ventilation and Air-conditioning HVAC System
Security and observation system
Magnetic card and access system
Fire alarm system
Lifts , elevators etc.
Plumbing system
Burglar alarms
Other engineering systems

Save time and money during the maintenance
Building automation describes the functionality provided by the control system of a building. A building automation system (BAS) is an example of a distributed control system. The control system is a computerized, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems in a building.
BAS core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and device failures and provides email and/or text notifications to building engineering staff. The BAS functionality reduces building energy and maintenance costs when compared to a non-controlled building. A building controlled by a BAS is often referred to as an intelligent building system.
Platinum Park Phase 4 Felda Tower consists of 50-storey offices, 1000 seaters ballroom and
event facilities within the booming KLCC area. With the vast amount of solid waste generated
from all these amenities, our client has decided to install a cost effective and efficient
Automated Waste Collection System (AWCS). The STREAM system is tailor-made to meet
their specifications. Load stations are located within short distance from catering facilities to
ease the whole disposal process whilst maintaining the required hygiene standards
The illustration below shows the basic concept of how a standard STREAM Automated Waste
Collection System (AWCS) works:
1. Chutes that are used to feed waste into the system
2. Storage section that holds the waste between transport cycles
3. Primary air inlet that creates an active high speed air path in the pipe network
4. Discharge valves that periodically open to allow movement of the waste into the active air path
5. Transport pipes that form the waste path between the storage chambers and the Central Waste
Handling
Facility (CWHF)
6. Outdoor load stations that may also feed smaller quantities of waste material into the system
.
STREAM AWCS
Type of STREAM: Full Vacuum
Total Pipe Length: 120m
Number of Fractions: 1
Estimated Waste per Day: 1 metric ton

Platinum Park To Go Green
Platinum Park is to be an environmentally sustainable development that will
conform to the newly launched Malaysia Green Building Index (GBI) .
In conforming to the GBI the development core design will include greater energy
efficiencies, improved Indoor environmental air quality, sustainable site planning
& management, sustainable materials & resources and water efficiency . The
three office towers of the development presently under construction that is the
Felda
Tower, Naza Tower and yet-to-be-named 38 storey tower will be among the
pioneer recipients of a GBI rating.
With the buildings of Platinum Park conforming to GBI and blending harmoniously
with the surrounding environment and local climate , this high-end residential
and commercial development is well destined to become an iconic development
in Kuala Lumpur.
The curvilinear, sculptural forms of the Platinum Park towers reference trees in the
forest, stretching towards the sunlight.
Key Features
The 9 acre Platinum Park development will establish a unique living and
working community in the heart of Kuala Lumpur. As the second largest mixed-
development in the heart of Kuala Lumpur after KLCC itself, Platinum Park offers
something that no other city-centre development can – a synergistic blend of retail,
commercial and residential components all tied together by a lush central park and
topped off with direct MRT connectivity.
Platinum Park comprises 2 luxurious residential towers, 3 Grade-A offices
towers, a hotel & serviced residence, a 1.5 acre park and 150,000 sq ft of niche,
boutique retail space.Its striking residential towers with dramatic cantilevers evolved
through mathematical analysis to achieve the best views of the city from the
apartments, past the surrounding buildings – they rise above a new shopping and
entertainment quarter, which will provide a dynamic new social focus for Kuala
Lumpur City Center.
Foster + Partners has designed the second phase of the masterplan,
comprising two 53-storey residential buildings and a third tower, which is planned as
a future development and includes a luxury hotel. They rise above a public podium of
stepped landscaped terraces lined with shops, cafes and open air dining.
Description
The design concept for the towers is driven by a sense of place, inspired by
Malaysia’s tropical landscape and rooted in Kuala Lumpur’s urban grain. Their form
relates directly to the position of the surrounding skyscrapers – just as trees in the
rainforest stretch above the canopy to reach the sunlight, the towers rise upwards
and extend laterally to benefit from the best possible views of Petronas Towers and
the Royal Selangor Golf Course from the site. By concentrating the buildings’ mass at
the upper levels, the design maximises the public space at their base. This has
resulted in an innovative structural solution, using a network of sheer walls to transfer
loads down the slender ‘legs’ of the towers.
At the centre of the development is a large, open-air venue for performances and
events and car-free public spaces that open up new pedestrian routes from Jalan
Binjai and KLCC Park. The design of the stepped terraces establishes a natural
hierarchy of privacy, from public spaces, shops and restaurants at the ground and
lower levels; two levels of private residents’ facilities, including a tennis court,
swimming pools and cabanas; and an exclusive residents’ sky-lounge at level 50 with
spectacular views of the skyline.
The environmental strategy embraces both the public spaces and buildings – the
walkways are sheltered by canopies, the terraces and squares integrate cooling
water features and the unique form of the towers helps to promote air flow at ground
level. Together, these measures will achieve Malaysia’s Green Building Index
certification.
Luke Fox, senior partner at Foster + Partners, said:“The design of Platinum Park
maximises living spaces with spectacular views of KLCC at the top of the towers and
will create a thriving new quarter at their base with a range of shops and leisure
facilities – both for residents and the wider community. We have considered the
spaces between the buildings as carefully as the form of the towers themselves – the
new high-rise cluster will be a dramatic addition to Kuala Lumpur’s skyline.”

CONCLUSION
A research survey has been conducted to investigate the perceptions of Industrialized Building Systems (IBS) and the underlying reasons for the current poor reception of the system in the Malaysian construction industry. Based on the survey conducted, the following conclusions can be made:
1) Industrialised Building System (IBS) in Malaysia is perceived to be a system of construction which can offer benefits of speed, quality and safety to construction projects. IBS in Malaysia is also perceived to have a good technology.
2) IBS, however, is not perceived to be a system which can provide cost reduction compared with traditional in-situ construction. In fact, IBS project proposals are often rejected solely on the basi s of cost.
3) There is a strong indication that many in the industry are reluctant to switch to the IBS method of construction. Consequently, many will not recommend the use of IBS in their future projects.
4) The underlying reasons for the cold reception of IBS are as follows:
(a) The perception of the high cost of IBS as in (2) above. The high cost is believed to be due to lack of economy of scale in IBS projects and business monopoly by the small number of IBS producers in Malaysia (b) The perception of a state of failure in IBS technology transfer. A large faction of the industry feels that the technology transfer in IBS is a failure. They claim that there are insufficient IBS guidelines and unclear standards for IBS. (c) Resistance to change It is human nature to resist change from the more familiar to the less familiar (IBS) method of working. (d) Conventional in-situ system is still attractive. Industry professionals are still confident with the conventional in-situ system, which has been proven to be a relatively cheap, open, flexible and reliable method of construction.
Conclusion
Like limestone ratic karst topography commonly found in Kuala Lumpur Limestone is
formed by a chemical dissolution process. The dissolution of limestone is a very slow
process compared to human life span. of deep dissections, potholes
The karsts consist les, steep depressions and solution channels, resulting in erratic
limestone rock bedrock profile that posts great uncertainties and challenges in
foundation construction.
Sinkholes are usually triggered by ruction activities due to: loss of fines through
groundwater seepage, lowering of groundwater table, imposing of additional loads,
vibrations, direct punching of cavity cover by boreholes or piling. Limestone covered
by thin soils is more susceptible to occurrences of sinkholes. ne profile of 60m to
more Abrupt drop in lime store than 100m have been observed within some building
sites located near contact zones or fault zones.
