Conclusion

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

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.
