3. 1.0 INTRODUCTION
The site of this project is located at Belum Rainforest Resort, Pulau Banding, Perak. It is a Nature Appreciation Centre (NAC) for the site
itself. Nature Appreciation Centre is a centre that educates our societies and future generations to appreciate the natural world, but most
importantly is to give a direct experience of natural world. The occupants of this building is more on local visitors and tourists.
This project requires students to utilize a portion of their own design project in previous semester. Then each student should propose the
alternative to the existing construction systems to include different, more complex and recent building technologies. Finally, a complete
documentation including a report and a set of working drawings of the modified design shall be produced. Changes should be carried out on the
following building systems and components:
i. Floor system
ii. Wall system
iii. Roof system
iv. and to include a new basement level (shown only in sections)
The aim of this project:
i. To encourage analytical and critical study of the principles, practices and details of construction technology in the existing building.
ii. To encourage students to explore alternative construction systems
iii. To adapt and implement the alternative construction systems into the students’ design.
iv. To develop the students’ skills in producing working drawings.
Figure 1.1 to Figure 1.3 show the existing floor plan of the NAC. The highlighted area is the chosen area to carry out this project. The form
of the building is slightly changed from it’s previous form in this project but the spaces itself remain the same (Figure 1.4 to Figure 1.6).

(a) TIMBER FLOORING SYSTEM (EXISTING)
Timber flooring is also known as wood or plank flooring where generally recycled or reclaimed
wooden boards are installed to make flooring (Figure 1.7). It is commonly known as planking as it
makes use of hard board wood planks. Planking is preferred over many other types of flooring due to
the aesthetic appeal it provides to the interiors. The colour and types of wood used rely on the demand
and budget of the customer.
(b) REINFORCED CONCRETE FLOOR SLAB (PROPOSED)
Reinforced concrete floor slab is a commonly system used in modern buildings nowadays. It is
usually 50 millimetres and 100 millimetres thick. Concrete slab can be prefabricated or in situ.
Prefabricated slab is built in a factory and transported to site whereas in situ slab is built on the building
site using formwork (Figure 1.8).
(c) COMPOSITE STEEL DECKING SYSTEM (PROPOSED)
For a composite steel decking system, the top surface remains flat while the underside is
modulated whereby the concrete is poured into a corrugated steel deck (Figure 1.9). This improves the
strength and prevents the slab bending under its own weight. The corrugations run across the short
dimension, from side to side.

water resistant.
Costly
• The major disadvantages for timber flooring is that
it is very expensive
Better Acoustics
• A properly installed hardwood floor would not give
hollow sounds or vibrations.
Non resistant to Stains
• Not as hard as Granite or Marble so it’s prone for
scratches.
Low Maintenance
• Easy to clean and maintain on a daily basis.
Regular Maintenance
• Requires regular maintenance to prevent termite
attack if the building is located in an area which is
prone for termite attack.
Eco Friendly
• Timber is both renewable and recyclable.

14. 2.1.4 ADVANTAGES AND DISADVANTAGES
Composite Steel Decking System
2.0 DESIGN MODIFICATION
ADVANTANGES DISADVANTAGES
Lightweight Design
• The reduced self weight of composite elements
has a knock-on effect by reducing the forces in
those elements supporting them, including the
foundations
Crack
• The biggest problem is cracks.
• All composite will crack sooner or later.
Reduced Overall Construction Depth
• The floor depth reductions can be achieved using
composite construction
Brittle
• Composites are more brittle than wrought metals
and thus are more easily damaged
• Cast metals also tend to be brittle
Speed Construction
• The time taken for the installation is shorter
compare to timber flooring system
Repair introduces New Problems
• Materials require refrigerated transport and
storage and have limited shelf lives
Cost Savings (services)
• The floor depth reductions that can be achieved
using composite construction can also provide
significant benefits in terms of the costs
of services and building envelope
Might cause Overloading
• During placement of concrete, care should be
taken to avoid overloading the decking or
supporting structural members

(a) EXTERNAL TIMBER CLADDING (EXISTING)
Timber cladding is one of the environmentally friendly methods that is used to clad buildings.
Boards or planks of wood are used to form the exterior of a building. Besides, It is also used to
protect the structure of a building. Softwoods and hardwoods are used as cladding materials.
Timber cladding can be installed vertically, horizontally or even diagonally. Figure 1.12 is an
example of vertical external timber cladding.
(b) EXTERNAL VINYL SIDING (PROPOSED)
Vinyl siding, which is also types of the wall cladding, is the exterior material applied to the
wall of a house or other building meant to shed water, protect the walls from the effects of
weather, and is a key in the aesthetics of the structure. It is made from polyvinyl chloride (PVC),
the same stuff that serves so ably in plumbing drain lines. Its popularity continues to grow
because of new product offerings and features such as wood-like textures, shingle- and shake-
style panels, more appealing trim components and deeper colours. (Provey, 2010)
Vinyl siding can be applied either vertically or horizontally, depends on the customer. It may
be attached directly to the building structure (studs in the case of wood construction), or to an
intermediate layer of wood (boards, planks, plywood, oriented strand board) called sheathing.
(American Builder, 1946)

Client Wray and Sarah Warner
Contractor Schumacher Homes
Project Size 20 acres of land
Products Used Ply Gem Vinyl Siding
Searching for the house they have dreamed of near
Charlotte, N.C., proved to be a challenge for Wray and Sarah
Warner. This couple could not find an existing space that would
ideally meet their unique needs and busy, professional lifestyles.
Therefore, they bought a 20 acres of land on which they
could build their own custom dream home. Then, the Warners
turned to Schumacher Homes -- a national leader in custom on-
your-lot homebuilding, to make their dream a reality. Shortly after
selecting their builder, the Warners were selected as the winner
of the “Great Green Giveaway,” a promotion Schumacher Homes
was running with Ply Gem, giving the couple the opportunity to
upgrade their custom home using The Designed Exterior™ by
Ply Gem.
The builder combined energy efficient, low-maintenance Ply
Gem products including insulated vinyl siding; polymer shakes
and shingles; stone veneer; and aluminum-clad wood windows.
The result is a two-story home that blends the timeless charm of
a center hall colonial with today’s modern amenities. Since
nearly all of the exterior products are low maintenance, the
house is ideal for this busy couple.

ETFE system Steel truss with concrete tiles
(a) ETFE SYSTEM (EXISTING)
ETFE (Ethylene Tetrafluoroethylene) has been originally developed by DuPont
over 40 years ago as an inert coating material for the aerospace industry. ETFE is
being considered the material of choice for traditional skylight applications to long
span structures and building facades. Few building materials can match ETFE for its
impact or presence when you want a structure that stands out from the crowd.
Beijing National Aquatics Center is one of the good example that uses ETFE
system (Figure 1.18). The architect used ETFE to cover a total area of 100,000
square meters composing bubbles and 3000 give it a feature allowing an excellent
light throughout the facility but also by filtering ultraviolet rays.
(b) STEEL TRUSS SYSTEM (PROPOSED)
A steel truss is essentially a triangulated system of straight interconnected
structural elements. Steel trusses are used to carry the roof load and to provide
horizontal stability. It has become one of the most common roof truss system
nowadays (Figure 1.19). Next, trusses comprise assemblies of tension and
compression elements. There are many truss types, like mono, bowstring, studio
vault and more. Most roof trusses have webs that run at an angle between top and
bottom chords. One exception is the gable-end truss in which webs run vertically.

Since the over exhaustion demand on timber has caused the
timber roof truss construction to grow scarce, the architect of
Polytechnic Kulim thinks that steel truss is an excellent substitute
and as the steel truss is a galvanized based material. It has
demonstrated to be a very enduring protection.
All of Bestweld Steel System products are cold-formed from
either zinc/aluminium aloy or zinc coated steel to preserve the
quality of the trusses. Polytechnic Kulim chose Bestweld Steel
System Sdn Bhd as the company manufactures a full range of
steel roof truss systems which includes truss sections, roof batten
and its accessories that meets all international standards.
Polytechnic Kulim applied these reliable and high-quality roof
trusses.
Another reason steel truss was chosen is that steel is a
superior product for long term investment, with the added
advantages of being light, strong, non-combustible, termite proof
and will not shrink or wrap.

ADVANTAGES DISADVANTAGES
Elasticity
• While ETFE films are very elastic (up to 600% at breaking
point), they are still structurally resistant. The tensile
strength at the limit of elasticity/plasticity is 21-23 N/mm²
but tensile strength to breaking point is 52/Nmm². For
structural calculation a limit of 15 N/mm² is conservatively
usually taken.
Safety/Explosion Risk:
• As a flexible material, ETFE Foil can take very high
loadings for a short period of time which makes it an
ideal material for use in locations where there is a risk of
explosion.
Light Weight
• Weighs as little as 1-3% of traditional cladding systems
Poor Sound Insulation
• Transmits more sound than glass
Exceptional Light Transmission
• Can be highly transparent (from 90% to 95%) and allow
for the passing of UVs which are responsible for the
promotion of photosynthesis thus facilitating plant growth.
Not Suitable for Small Buildings
• Usually applied in several layers that must be inflated
and require steady air pressure thus working with ETFE
is difficult for small building projects
Low Carbon Footprint
• Carbon footprint is approximately 80 times lower than
comparable transparent systems
Fragility
• Prone to punctures by sharp edge

Bad Sound Insulation
• Sound is more easily transmitted with steel trusses
compared to timber trusses
Fire Resistance
• Steel trusses offers a safer building as there is less threat
of the building being completely destroyed by fire or other
natural disasters
Costly
• Steel is usually more expensive than timber.
Environmentally Friendly
• Greatly reduces the amount of trees that are cut down for
use in building
• Requires no “wet work,” which makes the construction
process much faster as only the simplest assembly is
required
• Steel construction materials are 100% recyclable

WATER PROOFING SYSTEM
Basement Waterproofing is a technique used to prevent water from
entering the basement of a building. It plays an important role as it helps to
keep the building dry. It includes both drainage and sealers. Waterproofing is
needed anytime a structure is built at ground level or below ground.
Besides, waterproofing and drainage considerations are especially needed
in cases where ground water is likely to build up in the soil and raise the water
table.
Lastly, waterproofed basements can be converted into kitchens,
bathrooms, wine cellars, living rooms, studies, or even recording studios.
