This document discusses methods for preliminary cost estimates of construction projects. It defines preliminary estimates as a way to forecast potential project costs early in the design process. Three common methods are described: unit method, which estimates costs based on units like students or beds; cubic method, which calculates volumetric costs; and floor area method, which estimates costs per square meter. Each method has advantages like speed but also disadvantages like lack of design detail. Experience is needed to select the appropriate preliminary estimate method based on available information and project type.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2. DEFINATION AND IMPORTANCE
OF PRELIMINARY ESTIMATES
DEFINATION
Defined as an activity in particular work to make
possible offer to execute task base on a stipulated sum
Technique to forecast the possible cost incurred for a
certain building or construction project via a systematic
calculation employing certain method, prepare at early
stage of the project
Is a part of the cost planning process that is controlling
of the project cost at the design stage before any
drawings are embarked upon.
3. USE OF THE PRELIMINARY
ESTIMATE METHOD
To ascertain the actual cost forecast of a
project.
Assist the client in knowing to what extent he
need to be financially committed to a
particular project
Estimated is also function as a design guide
whether the project to the allocation made
either
4. Cont’d
If the estimate is higher that the client budget
for that particular project, the following could
be carried out :-
The design could be altered to reduce the
cost
Extra provisions are sought after or
requested from the client
The project is postponed or cancelled
5. Cont’d
If the estimate is low than the allocated
sum, the following could be done
Accept the estimate
To modify the design and/or the
specifications to increase the estimate
appropriate to the provision set aside.
7. METHOD WHEN IT IS USED NOTE

volume of air-
conditioned space or
space which is given
mechanical ventilation
Cost/m3
FLOOR
AREA
Outline proposal
Used extensively, can
be used for almost all
types of building
Cost/m2
8. THE SELECTION OF THE
METHOD WILL DEPEND ON
The information and time to prepare the
estimate
The experience of Quantity Surveyor
The total and type of cost data available
9. UNIT METHOD
This method is also referred to as ‘cost according to
building function’
Estimate the building cost base on the size depends
on the population unit
Example: the total number of student in a
school, total number of bed in a hostel or hospital
and etc.
Easier method but the most unrefined.
Total population can be obtained from the client or
the design team
10. USAGE
The cost estimate is obtained by multiplying the
number of accommodation for a new building with
the cost per unit of accommodation based on a
suitable building
The current unit of accommodation can be obtained
by calculating from the sketch design or by
obtaining information from the client.
11. Example:
Estimate the total cost to build a mosque to house a
congregation of 500 individuals.
From a suitable cost data, get the cost/ congregation of a
similar mosque that has been updated. Lets us say that the
cost is RM 1400.00/ congregation.
Total cost = Number of accommodation x cost/congregation
500 individuals x 1,400
= RM 7000,000.00
12. CUBIC METHOD
In Malaysia this method is seldom or almost
never used
Only in certain case, it is utilized
To calculate the space which is need to be air-
conditioned
To calculate the space that needs mechanical
ventilation
13. USAGE
Measure the volume of the new building and
its volume is then multiplied with the suitable
price rate per m3
Unrelated works is to be volume must be
calculated separately
The volume of the building is calculated as
follows:
Volume = length x width x height
14. i. Height of pitch roof
from the top surface of the foundation to
half apex / height of roof
ii. Height of flat roof
From the top surface of foundation to 600mm
above the flat roof or parapet wall
(which is higher)
16. Example
Estimate the total cost to build a 2-storey bungalow if the
construction cost/m3 of a similar construction is RM
550.00. estimate the construction cost base on
a) Pitch roof
b) Flat roof
18. a) Pitch roof
Building volume = 20.00 x 10.00 x [1.00 +2(3.50) + ½ (1.50)]
=20.00 x 10.00 x 8.75
=1750m3
Total building cost = volume x cost/m3
=1750m3 x RM550.00
=RM962,500.00
19. b) Flat roof
Building volume = 20.00 x 10.00 x [1.00 +2(3.50) + 0.60]
=20.00 x 10.00 x 8.60
=1720m3
Total building cost = volume x cost/m3
=1720m3 x RM550.00
=RM946,000.00
20. Floor area method
Make a preliminary estimate as most of the cost data
are kept or are available in this form
The measurement for GFA must be similar between
the new building and the analyzed building
Need to consider criteria in measurement of area
In the calculation the floor area of a building there are
several criteria need to be taken
1. The actual area of the building
2. If the project offers a standard or different type of
accommodation it is better for each to be priced separately
3. Unrelated work to the area, for example, external work
must be priced separately
21. Cont’d
The rate per m2 chosen must be current rate as
building cost often differ
The site, external works, condition of contract, the
quantity and the quality of equipment and others that
related to the floor area must be calculated separately
It is clear and difficulty of this method lies in
choosing the appropriate rate, which requires
experience, observation and familiarity toward varied
building types
22. USAGE
The floor area of a building to be erected. Only the
building used this floor area method. Other works
may use other method like approximate quantity.
Total cost = area x cost/m2 gross floor area (GFA)
Area – calculate the area of the building. The
measurement method differs according to
practices
Cost/m2 GFA – from similar building type and
function
23. EXAMPLE
Estimate the cost of the building by referring to the plans
given if the construction cost is RM 1,500/m2

Ground floor
25.00 x 5.00 = 125.00
10.00 x 3.00 = 30.00
5.00 x 7.00 = 35.00
190.00
First floor
25.00 x 5.00 = 125.00
10.00 x 3.00 = 30.00 155.00
345.00
Total cost = area x cost/m2 Gross Floor Area
= 1500.00 x 345.00
= RM 517,500.00
25. UNIT CUBIC FLOOR AREA
Fast and easy
Easiest method to
obtain cost limit to
prepare the monetary
allocations for several
years to come
No necessity for
drawings
The estimate can be
prepared quickly
The client and
architect easily
understand the
concept of floor area.
most work items are
appropriately
associated with the
concept of floor area
rather than the
volume method
Cost data easily
available as most of
the data from
previous project most
utilize this method
ADVANTAGES
26. DISADVANTAGES
UNIT CUBIC FLOOR AREA
An unrefined method
and in accurate. Only
suitable to provide
and overall
approximate estimate
Does not take into
account changes to
plan, number of
storeys and other
factors related to
design
Unrelated work
concerning unit of
accommodation has
to be calculated
separately.
Does not take into
account changes to
plan, height, of storey
and the overall height
of the building
Unrelated work to the
volume has to be
calculated separately
Does not help
architect in design
work as it is difficult
to predict or to know
the effects of the
changes to
specifications, design,
etc. to the cost per m3
Difficult to obtain
similar cost data
Does not take into
account changes to
plan, height, of storey
and the overall height
of the building as
these factors effect the
building cost
Other work which are
not related to the
floor area must be
calculate separately
Difficult to calculate
and allocate the cost
for different site
conditions, quality of
materials, condition
of contract and etc.
