 ESTIMATE
An estimate of the cost of a construction
job is the probable cost of that job as
computed from plans and specifications.

For a good estimate the, actual cost of the

proposed work after completion should not
differ by more then 5 to 10 % from its
approximate cost estimate, provided there
are no unusual, unforeseen circumstances.
 ESTIMATION
Estimation is the scientific way of
working out the approximate cost of
an engineering project before
execution of the work.

It is totally different from calculation of

the exact cost after completion of the
project.
Estimation requires a thorough Knowledge
of the construction procedures and cost of
materials & labour in addition to the skill ,
experience, foresight and good judgment.
 NEED FOR ESTIMATE
1. It help to work out the approximate cost of the
project in order to decide its feasibility with
respect to the cost and to ensure the financial
resources, it the proposal is approved.

2. Requirements of controlled materials, such as

cement and steel can be estimated for making
applications to the controlling authorities.

3. It is used for framing the tenders for the works

and to check contractors work during and after
the its execution for the purpose of making
payments to the contractor.

4. From quantities of different items of work

calculated in detailed estimation, resources are
allocated to different activities of the project and
ultimately their durations and whole planning
and scheduling of the project is carried out.
SITE CONDITIONS AFFECTING THE OVERALL COST
1 = Each type of work requires a different
method of construction. Construction may be of
an ordinary house or office and it may also be
of a Dam, Tunnel, Multistory building, Airport,
Bridge, or a Road, already in operation. Each of
these works requires totally different
construction techniques, type of machinery,
and formwork.

2 = Quality of labour and labour output varies in

different localities.

3 = Weather conditions greatly affect the output

and, hence, the overall cost.
SITE CONDITIONS AFFECTING THE OVERALL COST (-ctd-)

4. Ground conditions vary and change

the method of construction. For
example, excavation may be dry, wet,
hard, soft, shallow or deep requiring
different efforts.

5. The work may be in open ground such

as fields or it may be in congested
areas such as near or on the public
roads, necessitating extensive
watching, lightening, and controlling
efforts, etc.
SITE CONDITIONS AFFECTING THE OVERALL COST (-ctd-)

6. The source of availability of a

sufficient supply of materials of good
quality is also a factor.

7. The availability of construction

machinery also affects the method of
construction.

8. Access to the site must be

reasonable. If the access is poor,
temporary roads may be constructed.
 ESSENTIAL QUALITIES OF A GOOD ESTIMATOR

In preparing an estimate, the Estimator must

have good knowledge regarding the important
rules of quantity surveying.

He must thoroughly understand the drawings

of the structure, for which he is going to
prepare an estimate.

He must also be clearly informed about the

specifications showing nature and classes of
works and the materials to be used because
the rates at which various types of works can
be executed depend upon its specifications.
ESSENTIAL QUALITIES OF A GOOD ESTIMATOR (-ctd-)
A good estimator of construction costs should possess the
following capabilities, also:-

1 = A knowledge of the details of construction work.

2 = Experience in construction work.

3 = Having information regarding the materials required,

machinery needed, overhead problems, and costs of all
kinds.

4 = Good judgment with regard to different localities,

different jobs and different workmen.
5 = Selection of a good method for preparing an estimate.

6 = Ability to be careful, thorough, hard working and

accurate.

7 = Ability to collect, classify and evaluate data relating to

estimation.

8 = Ability to visualize all the steps during the process of

construction.
 ESSENTIAL QUALITIES OF A GOOD ESTIMATOR (-ctd-)
Before preparing the estimate, the estimator should visit
the site and make a study of conditions, there. For
example, if the construction of a large building is
planned, the estimator or his representative should visit
the site and:

Note the location of the proposed building.

Get all data available regarding the soil.
Make a sketch of the site showing all important details.
Obtain information concerning light, power, and water.
Secure information concerning banking facilities.
Note conditions of streets leading to railway yards and to
material dealers, and
Investigate general efficiency of local workman.
 TYPES OF ESTIMATES

There are two main types of estimates:-

1 = Rough cost estimate.
2 = Detailed estimate.

Depending upon the purpose of estimate,

some types of detailed estimate are as
follows:-
a) Contractor's estimate
b) Engineer's estimate
c) Progress estimate
 I = Rough cost estimate

Estimation of cost before construction from

plans or architectural drawings of the
project scheme, when even detailed or
structural design has not been carried out,
is called Rough cost estimate.

These estimates are used for obtaining

Administrative Approval from the
concerning Authorities.

Sometimes, on the basis of rough cost

estimates, a proposal may be dropped
altogether.
 Rough cost estimate (-ctd-)

Unit cost is worked out for projects

similar to the project under consideration
carried out recently in nearly the same
site conditions.

Unit cost means cost of execution of a unit

quantity of the work.
 Rough cost estimate (-ctd-)
To find rough cost of any project, this worked
average unit cost is multiplied with total quantity
of the present work in the same units.

For example, in case of a building, plinth area (sq.

ft.) of the proposed building is worked out, which
is then multiplied by the cost per unit area (Rs.
/ft2) of similar building actually constructed in
the near past in nearly the same site conditions,
to find out the rough cost estimate of the
building.

This cost is sometimes adjusted by the average

percentage rise in the cost of materials and
wages.
 Rough cost estimate
The rough cost estimate may be prepared on the
following basis for different types of projects:

1. Cost per square foot of covered area (plinth area) is

the most commonly adopted criterion for preparing
rough cost estimate for most of the residential
buildings.

2. For public buildings, cost. Per person (cost per

capita) is used. For example,

Students hostel-cost per student

HospitalsCost per bed

HotelCost per Guest

 Rough cost estimate (-ctd-)
3. Cost per cubic foot is particularly suitable for
commercial offices, shopping centers, and
factory buildings, etc.

4. For water tank/reservoir, cost may be worked out

on the basis of capacity in gallons of water
stored.

5. For roads and railways, cost may be found out

per mile/kilometer of length.

6. For streets, cost may be per hundred feet/meters

of length.

7. In case of bridges, cost per foot/meter of clear

span may be calculated.
 EXAMPLE

estimate and cost per Flat for a

multi-storey (4-storeyed) block

consisting of 40 residential flats.

 DETAILED ESTIMATE

Detailed estimates are prepared by carefully

and separately calculating in detail the costs of
various items of the work that constitute the
whole project from the detailed working
drawings after the design has been finalized.

The mistakes, if any, in the rough cost estimate are

eliminated in the detailed estimate.

Detailed estimates are submitted to the competent

authorities for obtaining technical sanction.
 DETAILED ESTIMATE

The whole project is sub-divided into different

items of work or activities. The quantity for each
item is then calculated separately from the
drawings as accurately as possible. The procedure
is known as "taking out of quantities".

The quantities for each item may be estimated

and shown in the pattern which is called "Bill of
quantities."

The unit, in which each item of the wok is to be

calculated, should be according to the prevailing
practice as followed in various departments of the
country.
 BILL OF QUANTITIES
Description No Measurements Quantity Total Remarks
Sr. No

 PRICED BILL OF QUANTITIES

Sr. No. Description of Item Unit Quantity Rate Cost Remarks

 DETAILED ESTIMATE

Each item of the work is then multiplied by its

estimated current rate calculated by a fixed procedure
to find out cost of the item.

At the end, a total of all items of the work are made to

get the total estimated cost.

The rates are usually as per Schedule of Rates for the

locality plus a premium to allow for rise in labor and
material rates over and above the schedule of rates.

A percentage, usually 5% is also provided on the total

estimated cost for the work to allow for the possible
contingencies due to unforeseen items or expenditure
or other causes, besides 2% establishment charges.
 DETAILED ESTIMATE

Besides drawings and details of measurements and

calculation of quantities (Bill of Quantities), the following
documents are also usually submitted with the detailed
estimate for obtaining Technical Sanction:

1. A report explaining History, necessity, scope and main

features of the project, its design, and estimate, etc.

2. Specifications lying down the nature and class of work

and material to be used in various parts of the work.

3. The abstract of cost (priced Bill of Quantities) showing

the total quantities under each sub-head, rate per unit of
measurement, and cost.

4. Calculation sheets showing calculations for important

parts of the structure. In fact, in estimating the art and
skill lies only in the computation of details without any
omissions, of all parts of the building or work.
 CLASSIFICATION DEPENDING UPON
PURPOSE OF DETAILED ESTIMATE
1- CONTRACTOR ESTIMATE

It is made by the contractor for determining

the price or prices to be bid.
It is usually a carefully prepared detailed
estimate.

2- ENGINEERS ESTIMATE

This type of estimate is made by the Engineer

(Consultant) usually for the purposes of
financing the work and for checking bids and
running bills submitted by contractors.
 3- PROGRESS ESTIMATES
These are made by the Engineer at
regular intervals for the completed parts
of the project during the progress of the
work for determining the amounts of
partial payments to be made to the
contractor.

On large contracts, such estimates are

commonly made each month and, hence,
are frequently called monthly estimates.
 UNFORESEEN ITEMS IN DETAILED ESTIMATE

While preparing a detailed estimate, one had to

be very careful to see that all items of the work
are incorporated.
It is likely that a few Items, though
unimportant in nature, might have been
overlooked and which may result in raising the
estimate of the project.
There may be also certain unforeseen
circumstances affecting the project.
Hence, a certain allowance usually 5 to 10%
of the total cost, is made in the estimation
which will take care of all these items that are
unforeseen or are overlooked and are known as
"Contingencies".
 METHODS OF DETAILED ESTIMATE
The dimensions, length, breadth and height or depth
are to be taken out from the working drawings (plan,
elevation and section).

Junctions of walls, corners and the meeting points of

walls require special attention.

For symmetrical footings, which is the usual case,

earthwork in excavation in foundations, foundation
concrete, brickwork in foundation and plinth, and
brickwork in superstructure may be estimated by either
of the two methods:

(1) SEPARATE OR INDIVIDUAL WALL METHOD

(2) CENTER LINE METHOD
SEPARATE OR INDIVIDUAL WALLS METHOD
The walls running in one direction are termed as
"long walls and the walls running in the
transverse direction, as "Short waLls", without
keeping in mind which wall is lesser in length
and which wall is greater in length.
Lengths of long walls are measured or found
"Out-to out" and those of short walls as "In-
to-in".
Different quantities are calculated by
multiplying the length by the breadth and the
height of the wall.
The same rule applies to the excavation in
foundation, to concrete bed in foundation,
D.P.C., masonry in foundation and super
structure etc.
 SEPARATE OR INDIVIDUAL WALLS METHOD
For symmetrical footing on either side, the
center line remains same for super structure,
foundation and plinth. So, the simple method is
to find out the centre-to-centre lengths of long
walls and short walls from the plan.
Long wall length out-to-out
= Center to center length + half breadth on
one Side + half breadth on other side.

= Center to center length + one breadth

Short wall length in-to-in = Center to Center

length - one breadth.
SEPARATE OR INDIVIDUAL WALLS METHOD
This method can also be worked out in a quicker way., as follows:

For long walls

First of all, find the length of the foundation trench of the long
wall out-to-out in the same manner as explained above.
The length of the foundation concrete is the same.
For the length of the first footing or first step of the brick wall,
subtract two offsets (2x6"=12") in foundation concrete from the
length of the trench or concrete.
For the second footing subtract from the length of the 1st footing
two offsets (2x2.25"= 4.5"), for 3rd footing subtract from the
length of the 2nd footing 2 offsets (4.5") and in this way deal
with the long walls up to the super-structure.

For short walls

Follow he same method but instead of subtracting add two offsets
to get the corresponding lengths in-to-in.
1 Breadth 1 Breadth
2 2

Foundation
Trench
 CENTRE LINE METHOD
In this method, total length of centre lines of walls,
long and short, has to be found out.
Find the total length of centre lines of walls of same
type, having same type of foundations and footings and
then find the quantities by multiplying the total centre
length by the respective breadth and the height.
In this method, the length will remain the same for
excavation in foundations, for concrete in foundations,
for all footings, and for superstructure (with slight
difference when there are cross walls or number of
junctions).
This method is quicker but requires special attention
and considerations at the junctions, meeting points of
partition or cross walls.
 CENTRE LINE METHOD
For rectangular, circular polygonal (hexagonal,
octagonal etc) buildings having no inter or
cross walls, this method is quite simple.

For buildings having cross or partition walls, for

every junction, half breadth of the respective
item or footing is to be deducted from the total
centre length.

Thus in the case of a building with one partition

wall or cross wall having two junctions, deduct
one breadth of the respective item of work
from the total centre length.
 CENTRE LINE METHOD
For buildings having different types of walls, each set of
walls shall have to be dealt separately.

Find the total centre length of all walls of one type and
proceed in the same manner as described above. Similarly
find the total centre length of walls of second type and deal
this separately, and so on.

Suppose the outer walls (main walls) are of A type and

inner cross walls are of B type.

Then all A type walls shall be taken jointly first, and then all
B type walls shall be taken together separately.

In such cases, no deduction of any kind need be made for A

type walls, but when B type walls are taken, for each
junction deduction of half breadth of A type walls (main
Walls) shall have to be made from the total centre length of
B type walls.
 CENTRE LINE METHOD

At corners of the building where two walls

are meeting, no subtraction or addition is
required.

In the figure, the double cross-hatched

areas marked P,Q,R, & S come twice,
while blank areas, A,B,C, & D do not come
at all, but these portions being equal in
magnitude, we get the correct quantity.
DESCRIPTION AND UNITS OF
MEASUREMENT FOR

COMMON ITEMS
 1 = SITE CLEARANCE WORKS

This item is described in detail but

the price of this item is usually
indicated as lump sum (LS).

The cost of this item is provided in

the estimate by judgment, according
to the description of the item and is
indicated as Lump sum (L.S).
 2 = EXCAVATION FOR FOUNDATION TRENCHES

Earthwork in excavation for foundation

trenches is calculated by taking the
dimensions of each trench as length X
breadth X depth.

It is measured in cubic ft, cubic yard or

cubic meter, according to the prevailing
practice.

The payment for this item is generally

done as Rs. per hundred cubic ft.
 FILLING IN TRENCHES
Filling in trenches after the
construction of foundation
masonry is ordinary neglected. If
the trench filling is, also taken in
account, it may be calculated by
deducing the volume of masonry
in trenches from that of the
volume of excavation.
 3 = FOUNDATION CONCRETE (P.C.C.)

The type of concrete must be clearly

mentioned. The mix proportions and the type
of cement, sand and coarse aggregate must be
specified.

This item is measured in cubic ft and the

unit for measurement is, generally Rs. per
100 cubic ft.

When the soil is soft or weak, one layer of dry

bricks or stone soling is applied below the
foundation concrete. The soling layer is
computed in sq.ft (length X breadth),
specifying the thickness in description of item.
 4 = BRICKWORK IN FOUNDATION UP TO PLINTH

Care must be taken, while taking dimensions

from the drawings in the bill of quantities
because the walls in this part of the structure
are in the form of steps with changing
dimensions.

This item is calculated in cft and the unit for

payment is Rs. per 100 cft.

In the description of work, the quality of bricks

and mortar ratio must be specified. For example,
"Brickwork in foundation and plinth using first
class bricks laid in (1:4) or (1:6) cement-sand
(c/s) mortar
 5 = BRICKWORK IN SUPER STRUCTURE
Important considerations are:

a = Measurements of walls shall be taken in the

same order and in the same manner as for
brickwork in foundations and plinth.

b = In the first measurements, all openings

such as doors, windows, veranda openings etc.
shall be neglected. However, deductions shall
be made for all openings in the walls, at the
end of the item.
 BRICKWORK IN SUPER STRUCTURE (ctd)
c = In the description of the work, the quality
of bricks and mortar ratio have to be specified.

d = Masonry for arches shall be paid separately,

at a different rate.

e = The height of super structure is very

important. Generally the quantities are
worked out for each storey separately and
rates would be different for different storeis
because of additional labor work, scaffolding
and shuttering.

f = The item is worked out in cft and the

standard unit for payment is Rs. Per 100 cft.
 6 = DAMP PROOF COURSE (D.P.C.)

Horizontal D.P.C. shall extend the full width of

the super structure walls, however, it shall not
be provided across doorways and veranda
openings. It is also provided in roof and floors.

Vertical D.P.C. is provided in external walls,

especially, in the walls of basements.

The quantity of D.P.C. is estimated in square

ft.(on area basis) and standard unit for
payment is Rs. per 100 sft.
 7 = ROOFING & RCC WORKS
Area of the Roof slab is calculated by taking inside
dimensions of the room plus a bearing of the roof slab
on the walls, on all sides.

For R.C.C. Roof slabs and beams, the total quantities

of concrete and steel are estimated, separately.

The quantity of plain concrete is estimated in cft and

the standard unit for payment of concrete is Rs. per
100 cft.

Volume of Reinforcing Steel is not deducted , while

estimating the volume of plain concrete for payment.

c = R.C.C. lintels over wall openings such as doors

and windows are also included in R.C.C. work.
 ROOFING & RCC WORKS (ctd)
Roof consisting of beams, battens, and tiles or wooden
planks is estimated for each part, separately.

Steel beam is estimated by weight, whereas, wooden

beam is measured in cft. Battens are estimated by
numbers indicating there size and lengths. Tiles are
also estimated by size and numbers.

Roof finishing may consist of bitumen coating and/or

Polythene sheets (water proofing) , earth filling (heat
proofing) and brick tiles, etc.

Dimensions are taken from inner face to inner face of

parapet walls.

This item is estimated in sft and a composite rate for

payment is taken as Rs. per 100 sft of the roof area.
 8 = REINFORCEMENT STEEL /
GENERAL STEEL WORK
Steel is provided separately from R.C.C.
per ton, per Kg, or per cwt (standard
weight also called Quintal or century
weight equal to 112 Ibs = 50Kg).

Quantity of steel can either be worked

out by rules of thumb practice or by
intensive calculations taking the length
and diameter of steel bars from the
working drawings showing reinforcement
details and bar-bending schedules. In
taking length of bars, due margin of
hooks, bends and overlapping is given
REINFORCEMENT STEEL / GENERAL STEEL
WORK (-ctd-)

As a Rule Of Thumb Practice,

for ordinary beams and slabs for residences,
assume 6.75 Ibs of steel per cft of R.C.C. work.
However, for R.C.C. columns, it varies from 8
to 10 Ibs per cft., because normally, we use
2% of steel in columns.

Percentage of steel means, area of steel

divided by total area of the column multiplied
by 100 and 1% of steel in columns corresponds
to a quantity of 4.5 Ibs/cft.
 9 = FLOORS
Cement concrete floors. Mosaic floors, and brick
floors are most commonly used.

Payments are made separately for different

layers, like, topping, lean concrete, sand filling,
earth filling, etc.

Earth filling, sand filling and lean concrete are

paid by volume, whereas, topping is paid on
area basis, mentioning thickness in the
description.

Standard unit for payment of topping is, usually,

Rs. per 100 sft.

The skirting is estimated in running ft.

 10 = PLASTERING
The type of plaster, proportioning of materials
and minimum thickness of plaster have to be
specified.

The quantity is calculated for total wall surface

without deduction for openings such as doors
windows, ventilators, etc. However, if the wall is
being plastered on both the faces, the deductions
for opening areas are made from one side only.

Standard unit for payment is Rs. per 100 sft.

Height is also specified for plastering because, for

greater heights, labor cost increases. The rate
varies according to the number of the storey
 11 = WOODWORK/CARPENTRY
The type of material used and the quantity of
finish required should be clearly indicated in the
description of the item.

The rate for any type of woodwork includes

cutting of timber to required sizes, joinery
work, fittings and fastenings, three coats of oil
paints or varnish, bolts, locks, handles, etc.

The measurements are taken for the overall

area of doors, windows, etc. If volume of
timber required for these items is to be finding
out, the computed area is multiplied with the
nominal thickness and an allowance of 25% is
made for wastage of timber.
WOODWORK/CARPENTRY (-ctd-)
Rectangular wooden beams, vertical
columns, trusses, etc., are measured in
cft.

Wooden stairs are measured in number

of steps and description of the item
includes the riser, tread, and width of the
steps.

Wooden shelves are measured in running

ft (RFT).
 12 = PLUMBING WORK/SANITARY FITTINGS

For water supply and drainage works in a

building, the pipe lines and sewer lines are
measured in RFT, while other items are
measured in numbers.

These items include wash hand basins

(W.H.B.), kitchen basins (which may be of
glazed ceramic, mosaic, or stainless steel),
water closets (W.C., which may be of European
type, or local type), flushing tanks (also
known as flushing cisterns), shower rose, and
all type of water tapes.
 PLUMBING WORK/SANITARY FITTINGS (-ctd-)
Within sewer lines, man holes or inspection chambers are
to be provided at every corner and also at a distance, not
exceeding every 50 ft inside the house and every 100 ft
outside the house.

The size of man hole may be 2.5ft X 2,5ft for low depths
and 3ft X 3ft, 4ft X 4ft or 5ft X 5ft for deep depths.

Drainage pipe lines outside the covered area but inside the
boundary wall are, usually, of R.C.C. with minimum
diameter 4 in, however, these are available in different
sizes.

Inside the building, drainage pipe is, usually, of C.I. with

minimum diameter 3 in.

Water supply pipes are, usually, G.I. pipes., estimated in

RFT in different dias.

Other accessories, like sockets, elbows, tees, reducers,

unions, etc., are estimated in numbers.
 13 = ELECTRIC FITTINGS

All the accessories used in electric

fittings are described in detail and
payment is done in numbers or RFT.

All wires and pipes are taken in RFT

while other items are taken in Nos.
