1.0 INTRODUCTION

In general, preliminary estimate is the first indication of the cost of a proposed project
and is often the amount most remembered by the client. When it comes to the preliminary
estimate, it should not be too low as this may require some explanation as the design
develops, should the cost increase nor should it be too high as this may prohibit the design
proceeding further due to client’s lack of funds. It is very important to know the cost that is
going to be used for the project whenever any construction project is proposed by the client.
This is to ensure that no additional money will be required and still within the allocated
budget. This will include the expenses of site preparation, labour materials, machineries and
plants, professional fees, taxes and other charges including the expected maintenance costs
and operating costs for the new structure that is going to be built.

Therefore, our firm GLOBE SURVEYOR SDN.BHD provide a basic service to
prepare a preliminary estimate for the proposed project. Our company has been appointed
as a QS consultant for a new construction project which is residential house that is expected
to commence in June 2022. The title for our project is “CADANGAN PEMBANGUNAN
PERUMAHAN DI SEBAHAGIAN LOT 11185 (PT 7220) DAN LOT 8310 YANG
MENGANDUNGI 122 UNIT RUMAH TERES 1 TINGKAT (TYPE A) DI ATAS PT 1413 – PT
1534, DI BANDAR SPRINGHILL, PEKAN JEMIMA, DAERAH PORT DICKSON, NEGERI
SEMBILAN DARUL KHUSUS UNTUK TETUAN ECO PRIMA SDN. BHD”.

Along the way, we will use some types of method that involve in estimating the
preliminary budget of the construction project. This paper also includes the types of cost
data that should be identified according to the following breakdown which is building works,
external/infrastructure works and preliminaries. The estimate will be calculated in
accordance with the current industry’s best practices. Olatunji and Sher (2010) as cited in
Ismail (2018) stated that updated information in any construction projects greatly facilitates
the estimators to produce more reliable project costs.

3.0 METHOD FOR PREPARING THE PRELIMINARY ESTIMATE FOR THE PROPOSED
PROJECT

In this case, the most suitable for method that we use for preparing the preliminary
estimate for the proposed project is gross floor area. Generally, the gross floor area is the
sum of the floor areas of the spaces within the building. This includes most parts of the
building such as all the finished areas including supporting areas. The reason why we use
gross floor area is because the preliminary estimate will give insight into the cost of the
project before detailed plans are drawn up. It is easy to us provide the cost that can present
with confidence to our client, using calculations determined on the latest software. However,
this method excludes any area for common vertical circulation, such as lifts, stairs, pipe
trenches and storage etc. The method starts from using the provided CAD files of the
building design to validate that they were accurate, offer updates on changes that had been
made, and utilize this to precisely measure the Gross Floor Area. In relation to cost
estimating practiced by the Quantity Surveyors, the traditional process by Peurifoy and
Oberlender (2002) as cited in Ismail (2018) involves kick-off meeting, work plan
establishment, estimates preparation, estimates documentation, reviews and adjustments,
project execution, and feedbacks upon completed projects. Once all the all the information
gathered, simply multiply the plot ratio by the size of the land. This will help our company
examine the feasibility of the project in terms of finances and other important factors, such
as opportunity costs.

4.0 TYPES AND SOURCES OF COST DATA FOR THE PROPOSED PROJECT

4.1 Types of Cost Data

Cost indices was using as our type of cost data. It is a method of breaking down cost data
in past year constructed and completed projects, therefore data has to be updated to reflect
the current price or price in the years to come for the estimated price (Haji Ahmad, 2011).
Basically, changes to the building cost is greatly influenced by the cost labour and materials
used in the construction of the building and it has to be taken into consideration especially
in the preparation of the Cost Planning. The index numbers are used to measure the
changes in the price of the tender received at different times. Almost all of the cost data
used by the Quantity Surveyor are historical data and these data are used to prepare cost
plans or estimates and this information has to be adjusted using indices. These index
numbers are used to update the information of historical cost to the current value or to
forecast price trend and future cost incurred. The common uses of indices are for cost

5

planning, prediction whether the market condition and price are stable, as adjustment to
price fluctuation and others. By using this method, it already compromised all the elements
in a building such as building works, external/infrastructure works, and preliminaries.

4.2 Sources of Cost Data

The first sources of data that we obtained are through Bill of Quantities from our
project. A bill of quantities (BOQ) is a document used in tendering in the construction industry
in which materials, parts, and labour (and their costs) are itemised (Bill of Quantities BOQ,
n.d.). Data are obtained through elemental format analysis, basic price list of materials if
available also overall costs for use with a single price estimating method. Example unit, m2,
m3. By using BQ as our sources of data, it already compromised all the elements in a
building such as building works, external/infrastructure works, and preliminaries.

The second source of data that we obtained is through Information Services such as
Arcadis. Arcadis is the world's leading company delivering sustainable design, engineering,
and consultancy solutions for natural and built assets. So, Arcadis provides a broad and
extensive construction cost database as a result of our diverse project expertise, allowing
us to handle the simplest to the most complicated projects entrusted to us by clients who
recognized our value and dynamism (About Us Arcadis, n.d.). Through Arcadis, we obtained
information such as construction cost data and it helps in finding the new price/rate for the
current project.

Last but not least, the sources of data that we obtained are through Government
Publication from the Department of Statistics Malaysia (DOSM). In the Department of
Statistic Malaysia, we obtained the building material cost index by category of building and
region. That is referred to Special Release 1 (Civil Engineering Work) and Special Release
2 (for Building and Structural Works) for Peninsular Malaysia. These Special Releases are
published monthly and can be obtained directly or by subscribing (Haji Ahmad, 2011).

5.0 HOW COST DATA IS USED AND REASONS FOR THE ADJUSTMENTS OR
AMENDMENTS

5.1 How Cost Data Is Used.
1. Cost Index is used in this project to obtain the cost data. The index numbers are used to

track the price variations of tenders received at various times. The quantity surveyor
must monitor these indices, as well as prospective cost fluctuation patterns, and evaluate
variances based on location in order to make price adjustments to past cost data.
2. To make the cost plan work properly, the data must be updated using indices. So, using
the formulas that are generally used, the overall cost of the project, the rate of elements,
and so on could be updated. Example of the formula:

New price/rate (current) = Base price X Current index
Base index

3. From the above formula, the percentage of price change can be calculated through
this formula:

% Change = Current index - Base index X 100%
Base index

4. The data that we obtain at the Base price is through Arcadis (2020).
5. The data that we obtain at the Current index is through the Department of Statistic
Malaysia.
6. The data that we obtain at the Base index is through the Department of Statistic
Malaysia.

5.2 Reasons for the adjustments or amendments.

As explained above, Cost Index is used in this project to obtain the cost data and the
Quantity Surveyor must monitor everything included in order to make price adjustments to
past cost data. Therefore, the following are some of the reasons behind the project's
adjustment:

1. Location of Project/Construction
One of the multiplying factors used to alter the building cost to account for changes

in location is the location factor. Because this project will be developed in Negeri Sembilan
which is under region C, the most recent index for that region is 108.40. Furthermore, when
a construction project's site is far from accessible resources, the project's cost rises.
Transportation costs for workers, equipment, supplies, tools, and other items rise with
distance, adding to the project's cost (The Constructor, 2021).

2. Fluctuations

A construction project might last for years before it is finished. The cost of materials,
tools, labour, and equipment may fluctuate from time to time during the construction process.
During the cost estimating process, these price variations should be taken into
account. Moreover, for contracts containing fluctuation terms (i.e. contracts that give
allocations for increases in the cost of the contractor's resources such as materials, labour
costs, plant, and overheads), the index is used to determine the rise in the construction cost
(Khairani Haji Ahmad, 2011).

3. Labour costs

Wages for labour vary by location. As a result, the local pay rate should be properly
considered. If the project must begin after many months of cost estimation, the likely
fluctuation in labour rates must be factored into the estimate. It's possible that adjustments
will be required to account for both labour availability and the actual amount received and
depending on the task that is being done, operative output will likewise vary.

4. Market conditions

The construction sector is one of the industries that generates a lot of income for the
country, but the economy has been in decline from the beginning of Covid-19, including
rising market prices. As a result, adjustments must be made depending on current market
conditions and the country's and world's present situations (Hastings Chivetta, 2021). In

8

addition, the local supply of contracts and the demand for work by available contractors
determine the market's competitive status and the effect of the tendering market may also
have an impact on the pricing utilized.

5. Profit and overhead
Profit and overhead are computed as a percentage of the overall cost of a work and

covers a contractor’s time and expenditures. Each contractor's percent margin is different.
On modest work projects, up to 25% can be included in some situations. Apart from that,
some construction companies accept as little as 3% in order to keep costs down to a bare
minimum. This will be taken into account by an estimator in his rough estimate for every
project.
6. Material costs

Material costs, transportation costs, and any relevant taxes are all included in
construction material costs. As a result, while determining construction material costs, all of
these variables must be taken into account. This is also impacted by the state of the
economy and the government's policies. For example, the government may raise import
taxes to encourage the use of local materials in the construction sector so that it may
continue to function during a crisis.

7.0 COMMENT ON THE LIMITATION/DIFFICULTIES IN THE COLLECTION,
ADJUSTMENTS AND APPLICATION OF THE COST DATA.

After going through some discussions and meetings, our group experienced a few
limitations or difficulties in the collection, adjustments and application of the cost data. First,
the difficulties we face is during the adjustment process that is the difficulty to find the latest
cost index for the proposed project used in this project. Other than that, we also face few
difficulties during application of cost data process, the difficult to find the latest cost for per
m2 for similar proposed building project which is semi-d houses. The limitation to find similar
location for cost per m2 for the proposed project estimation has been one of the reasons.
Next, our group found that the difficult to find cost index for base cost index and current cost
index for this project.

8.0 CONCLUSION
As expressed, the preliminary estimate is the initial indication of a project's cost and

is frequently the figure that the client remembers. When it comes to the preliminary estimate,
it should not be too low since this may necessitate some explanation as the design evolves,
should the cost rise, nor should it be too high because the design may be delayed according
to the client's lack of cash. When a customer proposes a building project, it is critical to
understand the cost that will be employed for the project. This is to guarantee that no more
funds are necessary and that the budget remains intact.

The most appropriate approach for calculating the preliminary estimate for the
proposed project in this scenario is gross floor area. The total floor area of a building is
usually equal to the sum of the floor areas of all the spaces inside it. This comprises the
majority of the structure, including all completed sections and supporting areas. For cost
data, we used cost indices. It is a way of analyzing cost data from previously constructed
and finished projects; as a result, data must be updated to represent current prices or future
prices for the estimated price. Meanwhile, the primary source of cost data comes from our
project's Bill of Quantities. A bill of quantities (BOQ) is a document used in construction
tendering that includes materials, components, and labour (along with their costs). We got
data from the second source using information services such as Arcadis. Arcadis is the
premier provider of sustainable design, engineering, and consulting services for natural and

14

built assets across the world. Last but not least, we received our data from the Department
of Statistics Malaysia through Government Publications (DOSM).

As previously stated, Cost Index is used to acquire cost data for this project, and the
Quantity Surveyor must keep track of everything included in order to make price
modifications based on previous cost data. As a result, the following are some of the reasons
for the project's adjustment which are location of projects/construction, fluctuations, labour
costs, material costs, market conditions and last but not least, profit and overhead.
