1.0 Introduction
Our site is designated to be in the heart of Kuala Lumpur, right next to the current
developing Tun Razak Exchange. It is strategically located near to the CBD as our
project consists of office tower and commercial retail spaces. This proposed project is
expected to be a vibrant, environmental friendly and economic development. Our
project will have a mix of commercial, office spaces and some entertainment. We plan
to have a plot ratio of 1:10 for this development as this has been proven to be a good
benchmark for commercial developments. This means that it will not be too crowded,
but also an efficient way of using the spaces that are available to us.
Around this area, there are many commercial office spaces and retail spaces across
the block as well as the proposed Tun Razak Exchange, which is expected to be
Malaysia’s most robust and innovative financial district. Since this area has been
definitively known as a financial precinct, we are also aiming to develop this land to
suit the requirements. We also intent to be the benchmark for future developments in
terms of green building and our efficiency. Our project complements the CBD and also
contributes to serve as a growth factor to many major companies.
This land parcel is strategically located between Telok Ayer Street and Cecil Street
which is one of the main roads towards the CBD. This location is easy to find and
offers a great variety of choices. This also gives the opportunity for the real estate
around the area to appreciate in value, hence encouraging more investors come in to
invest. There are a few landmarks which area Pavilion KL, Low Yat Plaza and Berjaya
Times Square just to name a few.
The site area is divided into 3 plots. Each of these plots have different area and
different usage. Plot A1 is 5990.80 sqm, which is designated for the building of
maximum 50 stories office tower and development of commercial retail spaces. Plot
A2 has an area of 1612.40 sqm, and it is open space area with F&B kiosk of less than
100 sqm. Plot A3 is only 180sqm, which is a subterranean space and it is to be
developed for part of a pedestrian walkway to the MRT station. This is done by
constructing an underground linkway passage for the ease of use. These 3 plots of
land will be used to their fullest potential in terms of green building and commercial
development.

1.1 Benchmark Project
The benchmark project set for this project is located at the centre of the city, Kuala
Lumpur, a corporate headquarter office tower comprising design and construction of
1 block of 32-storey office tower and 1 block of 9 storey carpark with 1 level of common
basement and external infrastructure works.
This high-rise building served as a landmark corporate headquarters designed for
business versatility with Grade-A intelligent features. A total of 25-feet high grand
lobby with spacious freedom with 9.5 feet floor-to-ceiling office space within 32 floors
with 3 distinctive zones that cater to multi-functional businesses. This building has
been certified by GBI as well as MSC compliant in recognition of their practice for
environmental design and construction. The office tower is complete with features that
provide fibre-optic backbone with 100% backup power supply with Building
Management System that ensures the optimal saving in energy and water usage and
real time monitoring of environmental changes including carbon monoxide levels.
Besides all the environmental features mentioned above, it is located at a strategic
location that have easy access to public transport like the bus, LRT, KTM and Monorail
stations.

1.2 Building Design Proposal
The land plot is divided in Plot A1, A2, & A3, each with distinctive functions and
purposes. Our team attempted to divide the usage of these plots accordingly to
achieve the maximum diversity and efficiency of land use.
Our proposed building design consists of several main elements:
1) Main Office Building
The main feature of this development, situated in Plot A1, is an approximately
100m high office tower, housing 25 floors of offices and the ground floor as
retails. The average GFA per floor is 2500m2. Floor to floor height is 3.6m per
floor, with ground floor being extended to 4.0m height.
The office floor area amount to 62,288m2, surpassing the required 61,730m2.
8. 8
2) Retail Block
Located next to the main office building in Plot A1 is a 4-storey shopping centre.
It acts as a façade facing Telok Ayer Street. Approximately 20 meters in height,
this structure consists of 1200m2 GFA per floor, amounting to 4,800m2 of retail
space.
Combined with the ground floor of the office building, these two spaces provide
7,300m2 GFA of retail zones.
3) Cafeteria
The landscaping area in Plot A2 will hold a cafeteria, with a maximum GFA of
100m2. This building will be located at the top right corner of the plot as
demarcated in the drawing.
9. 9
4) Basement
The basement level of this development will consist of underground parking and
pedestrian walkways. We have provided approximately 6,300m2 of parking
space, which translates to 418 total parking bays, out of which 311 serves for
office use, 37 for retail uses, and 70 additional bays for public use as requested
by the client.
There will also be an underground pedestrian walkway spanning from the end
of Plot A1 to Plot A3. It is estimated to be 95 meters in length and 6m wide.
An additional 30-meter long walkway is required to connect the proposed
development to the existing underground pedestrian walkway leading to an
existing MRT station.
5) Covered Pedestrian Walkways
10. 10
Situated around the office and retail blocks is the covered pedestrian walkways.
Two different widths of walkways (3.6m and 5.0m) are required for different
locations. We provided steel structures with glass canopy to cover the
walkways.
5.0m wide covered walkway is provided in front of the office block, before the
building setback line.
3.6m wide covered walkway is provided for the sides facing Telok Ayer Street
and Cecil Street to promote walkability around the area. Another stretch is also
built to provide access to the existing Methodist Church.
11. 11
6) Existing Methodist Church and its setback lines
The development is required to preserve the existing Methodist Church, and
adhere to the stated setback lines for at-grade and subterranean structures built
around it.
The existing Methodist church is located beside Plot A2 iof the development
land parcel.
Two distinct no-build and setback area need to be adhered while planning the
development.

2.9 Others (Allowance)
a) Utilities Detection Works - RM 45,000.00
Utilities detection works determine the existing utilities of the site located at subsurface
or above ground. Any gas, electric, telephone, cable, water and sewer lines identified
will be used to design other utilities services of the new proposed buildings.
b) Site survey/investigation - RM 80,000.00
Site survey/investigation is carried out at the construction site to gather information on
physical conditions that will be encountered during the performance of the work. Site
survey should determine all the unusual circumstances of the site, the state of existing
buildings that are to be demolished and the conditions of the adjacent buildings and
sites. Thorough site survey is to be completed to identify the effect to demolition to
other existing buildings around the site.
c) Geotechnical Investigation Works - RM 220,000.00
Geotechnical investigation is below-ground work to obtain information on physical
properties of soil and rock around site that performed by geotechnical enginners.
Geotechnical investigation works including surface and subsurface exploration, soil
sampling and testing which used to design earthworks and foundations for proposed
structures. Besides that, geotechnical investigation also used to measure thermal
resistivity of soils or backfill materials required for underground transmission lines, oil
and gas pipelines, radioactive waste disposal and solar thermal storage facilities.
33. 33
d) Hoarding and Signboard - RM 120,000.00
Hoarding is a temporary structure erected around perimeter of construction site to
secure them from view and prevent unauthorised access. It act as part of site security
system in ensuring health and safety for site workers, visitors and general public and
to prevent theft or vandalism. Signboard is a board that indicating both user and
corporate identity of professions which usually placed at the entrance of site.
e) Cadastral Survey (Plot A1, A2 & A3) (Allowance) - RM 50,000.00
34. 34
Cadastral Survey is a survey to determine boundaries
and area of a lot of land or more. It can be categorized as title survey and demarcation
survey. Title survey is whereby the survey is for registering the final title while
demarcation survey is to determine the boundaries of a land for the purposes such as
the land's location, land's area, or clearance for building construction. Cadastral
surveys are controlled by law and the surveys within the meaning of Section 396 of
the National Land Code (Act 56 of 1965). The cadastral survey carried out will be
certified by the Department of Survey and Mapping Malaysia (JUPEM).
f) Utility Connection Charges - RM 120,000.00
Connection charges recover the cost of installing and maintaining assets that allow
parties to connect to the transmission system and which are not normally used by any
other party. The utility connection charges consist of electricity, water, sewage and
telephone.
35. 35
g) Services diversion: electricity (Allowance) - RM 120,000.00
Moving the electricity cables or overhead power lines because they are affected during
construction work. For example, moving the meter and service cable when the
construction is completed or maybe alter the position of meter and service cable. We
can also move the service cable from internal to external position.
h) Traffic Impact Assessment - RM 50,000.00
Traffic impact assessment or TIA for short, is an important part of the preliminaries.
The officer of the assessment should be aware of the condition of traffic around the
area of construction. It is vital to engineers and transport planner to determine the
possible effects of development on the transportation and traffic system and to mitigate
and negative impacts. TIA will incur roughly RM 50,000 for this particular project.
i) Protection of Existing Roadside Trees - RM 150,000.00
On the other hand, protection of existing roadside trees is to maintain and preserve
the current trees around the construction site. This is especially important to us due to
the fact the client requires us to achieve a Platinum GBI standard. Hence, we think it
is justifiable to spend RM 150,000 for this item.
2.10 GBI Platinum Rating Allowance
The allowance for GBI Platinum Rating is 10% in this project, as from our
sources, we noted that the sum allocated for GBI purposes is usually 35% of the M&E
Works. As M&E Works usually substantiate 30% of the total contract sum, we decided
to apply 10% of the total contract sum after superimposing the two percentages.

A summary of our cost plan is shown in the table above. In Plot A1, we proposed
a 26 storey high-end commercial office tower with height of approximately 100m. A 4
storey shopping centre next to the main building is also provided. The basement area
of the land parcel is planned to provide parking bays of 15m2 per lot for these two
buildings, allocating 311 lots for office use and 37 lots for retail. These two
development amount to GFA of 62,288m2 for office area with rate of RM5,227/m2,
reaching a total of RM325,550,000. While for retail area, GFA of 7,300m2 is allowed
at a rate of RM3,929/m2 totalling at RM28,680,000.
Plot A2 is proposed to be an open space filled with park furniture and water
features. In addition, a single storey cafeteria with a maximum GFA of 100m2 is
provided. A total of RM380,000 is allowed for A2. Plot A3 will be used to develop an
underground pedestrian walkway spanning through A1 and A2. The walkway will be
connected to the nearby MRT station for public ease of access. We allocated
RM10,050,000 for development of the walkway and additional works to land parcel
such as demolition, covered walkway, roof garden, public car parks and site works.
To be able to meet GBI platinum rank requirement, there is an allowance of
RM35,460,000, constituting 10% of total building work cost. Besides that, a sum of
RM20,010,000 is provided for contingency, which is 5% of total cost including GBI
allowance. Finally, a cost escalation of RM21,010,000, consisting of 5% of total
amount including contingency, is allocated assuming that tender is called in one year.
To summarize, the total GFA for the whole development is 76,560m2. The final
amount totals up to RM441,140,000 with rate of RM5,762/m2. We consider the project
to be feasible and recommend the client to proceed as it has an advantageous location
to become a unique city attraction, providing great business opportunities.
