1.0 IntroductionThis report is an outcome of the technical study of the final project of arc 3011

specialized architecture design 2. The aim of the study is to gauge student abilities in applying

knowledge on building construction and materials acquired

throughout the course in selected project.

Project description

ThIskandar Malaysia (Figure 1.1) is an extensive

development in progress in and around Johor Bahru. The

Iskandar Malaysia was established on 30 July 2006 and the

gross total area of its development is deemed to cover 2,217 square kilometers, approximately

three times the size of Singapore.

Iskandar Malaysia being at such magnitude would naturally bring about extensive

development in infrastructure, public amenities and facilities including general concern on its

environmental impact. It would have to involve numerous external agencies such as investors,

developers, professional agencies, statutory bodies, and of course the general public.

The task therefore is to design for an incubation centre where all these agents could get

together and contribute their part for the holistic success of Iskandar Malaysia.

Multifarious Iskandar Malaysia Incubation Center (MIMIC) will be the centre where all

the external agencies, including the general public, would come together with the Iskandar

Regional Development Authority (RIDA) and offer their part in the overall development.

The centre will therefore have the following functions to fulfill:

2.0 Basic principleThe proposed MIMIC is located at a site with beautiful landscape and trees. Therefore,

the design intention is to bring people to outdoors rather than look through the windows.

Besides that, the organization of the program breaks the typical arrangement of office space

which is according to department. Therefore, the spaces are compartmentalized into smaller

spaces and the top of each compartment will be different in terms of view, material, lighting,

and experience. To achieve the goal of bringing people to outdoor, the top of some

compartments will serve as the terrace for the compartment above. The design concept is as

show in in figure 2.1.

The final proposal of the MIMIC is consisting of eight floors and each floor will be

cantilevered at different distance. Therefore, the light weight non-load bearing external wall at

the cantilevered floor and roof will reduced the thickness required for the floor slab and the

depth of the beam. Therefore, the roof and floor on top of the beams will direct transfer the

loads to the column and the non-load bearing wall is fixed between them.

In addition, the roof garden and water pool on the topmost floor will require bigger

column to support the load. In order to reduce the dimension of the column, the light weight

non-load bearing wall and precast concrete hollow core floor slab are ideal solutions.

The structural principle is as shown in the figure 2.2. The vertical column will transfer

the loads from the floor slabs through beams. The non-load bearing wall envelope the

structures and form an enclosure for the MIMIC.

3.0 Aesthetic intentionsThe appearance of the exterior of the proposed MIMIC has to be simple and harmony in

order to fit in the existing site. Therefore, the design of the boxes is simple and the richness

of the design can be achieve through the use of material, cantilevered spaces, void and solid

and framed views from the MIMIC.

The appearance of the MIMIC is compromise of timber and concrete. The concrete

appearance is applied in the compartment intended for incubatory function such as incubatory

lab, meeting rooms and administration office. Material selection needed to be simple as they

do not compete with the nature. The concrete material emphasizes the main function of the

MIMIC as incubation center and it creates a calm, peace and harmony spaces which could

enhance the environment of the incubatory lab.

On the other hand, timber appearance is a nice combination for concrete as it do not

draw attention over concrete but soften the appearance of the concrete in a harmony way.

The timber appearance also delivered the message of respect of the proposed MIMIC to the

nature.Figure 3.1: Combination of concrete and wood

4.0 Problems and limitationTo achieve the design intention, the spaces is compartment into smaller spaces. These

smaller compartment required thinner wall, floor and roof in order to create more usable

spaces. In order to have all the columns standing within the ground floor exterior envelopes

(Figure 4.1), the compartments on the upper floors which are cantilevered at different distance

has to be light weight in order to minimize the dimension of the column required. The smaller

column has another advantage since the spaces at each floor are not repetitive and the column

has to go through the usable spaces to support the upper floor (Figure 4.2 and 4.3).

The reduction of weight of each compartment can be achieved through the application

of non-load bearing wall and the precast hollow core concrete floor slab. However, non-load

bearing wall has practical problems of sound insulation, fire protection and smoke control

between neighboring rooms when joints are not properly designed constructed in terms of

their insulating and sealing functions. This is especially in the case when the following aspects

are not given adequate attention and not allowed for in the design and construction:

Deformation of the building fabric, e.g., due to dead and imposed loads Production-related tolerances Dynamic, horizontal floor displacements caused by wind pressure/ suction or seismic

actions

Differences in changes of length due to differing materials and temperatures.

5.0 Implication of costTo minimize the budget of the proposed MIMIC, prefabricated building elements are use

in the construction. When prefabricated element is used, the less onsite labor is required and

shorter construction period can be achieved. The prefabricated hollow core concrete floor slab

(Figure 5.1) and light weight metal stud cladding minimize the onsite wet construction and

reduce the wastage of building materials.

Besides the construction cost, the maintenance cost can be minimized as well through

the use of durable building materials that required minimum maintenance. Fiber cement plank

is a good product to use in place of wood where there is excessive moisture or a chance of

termites. The fiber cement plank required minimum maintenance compared to wood and thus

reduce the cost of maintenance. Prefabricated building elements that manufactured under

controlled environment has higher quality and durability.

6.0 Special design considerationsThe conception, design and construction of the faade are crucial. Not only for the

external appearance of the building, but also for the serviceability, durability, costs and energy

consumption of the entire building, the protection of people and property, and comfortable

interior conditions.

Furthermore, there is legislation covering sound insulation, fire protection, smoke

control and interior day lighting levels, depending on the use of the building. However, these

considerations are not compulsory due to the short project period.

Non-load bearing exterior envelope system is used in the proposed MIMIC. Such

facades are positioned totally in front of the structure and form an enclosing, additional

weatherproof envelope into which glazing, windows can be integrated as distinct elements.

All the requirements placed on the properties of the faade must be satisfied by

choosing suitable materials and components, and by ensuring that they fit-and are fitted-

together properly to guarantee long-term durability.

Besides that, the roof garden (Figure 6.1) is another element that required special

design consideration. Rooftop planting is a building science that required many specialized

detail from the type of plants to the maintenance and repair of the green roof. The roof garden

is different from common green roof as roof garden is accessible and thus has higher weight.

Besides that, it required high maintenance and more complicated irrigation system.

The main functional space such as incubatory labs and meeting rooms are required tobe conjoined together to from larger spaces. Therefore, operable partition (Figure 6.2) are

widely use in the proposed MIMIC. These partition need to provide a high level of acoustical

separation to prevent noise from disturbing adjacent activities and the partition finish need to

precisely match the permanent walls.

7.0 Sustainability goalsSustainability is one of the goals of the MIMIC that has to be achieved. Sustainability

does not only refer to energy efficiency, water efficiency and preservation of green. According

to the Green Building Index (GBI), material and resources occupy an important place in the

assessment of non-residential new construction (NRNC) as show in in Figure 7.1. Besides that,

construction management contributes in the GBI NRNC assessment (Figure 7.2). Therefore, we

cant deny the importance of the materiality and construction in order to achieve the

sustainability goals of MIMIC.

The use of prefabricated building elements will reduce the onsite wet construction and

the wastage on building material. Besides that, the use of regional material such as UCO

PLANK that are manufactured by the local leading company in producing fiber cement product

supporting the use of indigenous resources and reducing the environmental impacts resulting

from transportation.

In addition, instead of the common flat roof, the topmost roof is designed as the roofgarden. The best place of the proposed MIMIC, which is the highest point of the building, is

reserved for public. The roof garden can meet the design intention that brings people to

outdoor.

The use of the roofs of buildings as green roofs is one of the main strategies used in

bio-architecture to limit the environmental impact of the construction. In fact, they are

recommended by all the associations who promote sustainable building, both because they

contribute to the reduction of the buildings energy requirements and therefore the reduction

of CO2 emissions, and because they lead to many other economic and ecological advantages:

they temporarily absorb storm water and release it again slowly hence preventing floodsdue to the sewer network overflowing and slow down overloading of the network when

new urban settlements are built.

they filter urban pollution and reduce carbon dioxide they filter polluted storm water they cool the air by evapotranspiration of water vapour they reduce wind speed they promote the settlement of animal ecosystems they reduce the transmission of noise inside the building they reduce the effects of urban heat islands they increase the heat inertia of the roof they increase the heat resistance of the roof they protect the waterproof covering and increase its lifetime they are a tool of new architectural expression

8.0 Material selections

As mentioned in topic above, the exterior appearance of the MIMIC is compromise of

concrete and timber. In order to achieve the timber appearance, fiber cement plank with

timber appeal is used instead of the real timber plank. This building material exhibit a number

of advantages compared to wood, which are:

Non-hazardous to health

100% asbestos-free.Fire resistant

Does not burn easily Class "O" building material conformed to Uniform Building By-Law.

Durable

Resistant to rot and water damage. Not affected by termite or other insect/vermin attack. When used and installed correctly, it does not crack or warp. Chemical resistant to mild acid corrosion.

Environmental Friendly

Minimise the cutting of trees. Raw material comes from managed resources.

Dimensionally Stable

An autoclaved composite material with a stable crystalline structure which is resilient tochanges in temperature and humidity. Less shrinkage compared to air-cured products.

Surface Finish Versatility

Readily accepts a wide range of surface finishes, e.g. acrylic, emulsion, lamination,ceramic, stones, marble, etc.

Easy to install

Lighter weight building material, less labour intensive.Minimal Maintenance

Virtually Maintenance free - Cost effective.

The concrete appearance is achieve through the use of the composite fiber reinforced

concrete panel are used on exterior and interior wall and ceiling surfaces of MIMIC. Composite

fiber reinforced cement board, a lightweight and economical concrete material, gives the

building its clean, simple planes and lines.

In addition, the lightweight properties of the material also reduced the loads that the

floor slab has to carry. The thickness of the floor slab and depth of beam also reduce uponlesser loads are taken.
