---------------------------------------------------------------
 Estimate is the process of calculating
the quantities and costs of of various
items required in connection with
the work.
Estimated cost is the theoretical cost of the
work or the probable cost of the work.
Estimated cost = Theoritical cost/Probable
cost
*Q. The Estimated cost is
a. Theoritical Cost of the work
b. Actual Cost of the work
c. both a & b
d. none
Actual Cost=> It is the actual expenditure of
the work after the completion of the work
from the account register of the completed
work. Actual cost never include Profit given to
the contractors.
*Q. Actual Cost is:
a. Expenditure cost + Profit
b. Expenditure cost only
c. Expenditure cost – Profit
d. Estimated cost
*Q. If the Estimated cost of a work is Rs. 5
lakh only, then the possible actual cost of the
work can be:
a. Rs. 5,00,000/-
b. Rs. 5,00,500/-
c. Rs. 4,90,000/-
d. all of the above
Purposes of Estimating:
 To give reasonably accurate idea of
the cost of the work
 Estimating various materials required
to complete the particular work
 Estimating various categories of
labourers required

#ANALYSIS OF RATES:
Defn
: The method of determining the rate of
an item of work, considering the cost of
materials, cost of labour, hire charges of tools
and plants, overhead cost, profit etc is called
rate analysis.

b. Labour and hire of tools and plants
c. Material, Labour and Tools and plants.
d. Materials, Labour and hire of tools &
plants
Note: In rate analysis, Overhead =5%, Profit to
contractor =10%, so overhead including profit
or profit including overhead= 15%, cost of hire
of tools and plants = 3 % of cost of unskilled
labourers for that work.

# In General:Cost of materials = 65 to 70 % of
whole cost, Cost of labours = 30 to 35 % of
whole cost, cost of foundation and plinth =10
to 15 % of whole cost (For Building)
 Cost Breakdown of a building
work (CBS)
1. E/W cost =1-1.5 % of whole cost
2. Cost of concrete in foundation =5 – 6
%
3. cost of B/W = 30 – 34%
4. cost of ordinary flooring =5 – 6%
5. cost of roofing =18 – 20 %
6. cost of wood works = 16 – 20%
7. cost of plastering and pointing = 10-12
%
8. miscellaneous work =4 – 6 %
 CBS of Road:
1. E/w in Cutting/Banking = 14 % of
whole work
2. soling cost including stone +
consolidation = 44 %
3. cost of wearing coat(including
stone
aggregate+consolidation+bitumen
)= 22%
4. other items =20%
Purposes of Rate Analysis:
 To revise the schedules of rate
 to work out the cost of extra items of
work
 to examine the viability of tender
rates
 to fix up the labour contract rates
Requirement for Rate analysis:
 Correct information of market rates of
materials
 correct information of market rate of
various categories of labourers
 o/p of labourers or out-turn of
labourers
 knowledge of rate and out-turn of
various various tools and plants to be
used in the work
 up to date knowledge of construction
work
Factors affecting the rate analysis:
 Quality of materials
 proportion of mortar
 location
 facilities available with respect to
tools and plants to the site
 transportation facilities available for
materials, labourers to the site
 overhead charges ( 2 to 5 % generally)
 profit desired( work load/amount of
project)
 management
 experience of workers

#Some Examples of rate analysis:
#An analysis of rate of PCC(1:2:4) /m3 :
i. Volume of concrete = 1 m3
ii. Add 50 – 60 % in it to get dry
volume of PCC = 1.54 m3
iii. Cement = 1/7 *1.54 =0.22 m3
=0.22*28.8 bags= 6.3 bags
iv. sand = 2/7 * 1.54 =0.44 m3
v. Aggregate = 4/7 *1.54 =0.88 m3
vi. water= (w/c)ratio * cement
weight = 0.5 *(6.30*50)= 158 liter
*Costing:
I. Materials
 Cement =6.3 bags * unit rate of 1
bag = Rs…..
 Sand = 0.44 * unit rate per m3
=
Rs……
 Agg =0.88 * unit rate
 Water = 158 ltr * Rs. 0.3/ltr
=Rs……
 Total =Rs. X
II. Labourers:
 Skilled =1 nos. * rate = Rs……
 Unskillled = 4 nos * rate = Rs…..
 Total = Rs. Y
III. Contractors Overhead including profit:
= 15 % of (A+B)
Grand Total = 1.15 of (X + Y) is the unit
per m3
of PCC.

*Principle of Valuation:
 Cost depends upon the supply and
demand of property
 cost depends upon its design and
specification of materials used
 cost depends upon its location
 cost depends upon the purpose for
which valuation should be done
 cost is affected by age of property and
its maintenance condition
#Terminologies:
1. Book Vakue => Original cost of
building – depreciation till that year
2. Scrap or Junk Or Demolition value=>
It is the value of carefully dismantled
materials at the end of its utility
period after deducting the cost of
dismantling .( 8 – 10 % of value of
property), it may be –ve or zero or
+ve depending upon the cost of
dismantling
3. Salvage value=> It is the value of
existing structure/property at the end
of its utility period without
dismantling.( 8 -10 % of the value of
property), it is always zero or +ve but
never –ve
4. Distress value=> It is always lower
than market value due to financial
difficulty or insufficient knowledge of
market value. etc.
5. Monopoly Value=>It is always higher
than market value due to shape,
size,and location of property.
6. Assessed value=> It is recorded value
of property in the register of
municipality for taxes.
7. Obsolescense Value=> Loss in value
of property due to old/fashion out
model of property
8. Capitalized value => Net rent * years
purchase(yp ), where net rent = gross
rent – outgoings(repairs,taxes,loss
etc), yp =
1
(𝑖 𝑝+𝑖 𝑐)
where, ip =highest prevailing rate of interest,
ic = rate of sinking fund =
𝑖
(1+𝑖) 𝑛−1
, i =
rate of interestfor sinking fund, n=
future life of structure in year
9. Sinking Fund => It is the accumulation
of fund to reconstruct or replace the
structure/machine at the end of its
utility period, Annual Sinking Fund(I)
=S*Ic where, s= total sinking fund
10. Depreciation=> Types:
 Physical depreciation=> Due
to wear and tear, action of
time
 Functional Depreciation=>
Due to inadequacy of
hight,width,obsolescence etc.
 Contingent Depreciation=>
Due to structural defects(EQ,
FLOOD ETC)
#METHODS OF CALCULATING
DEPRECIATION:
1. Straight Line Method: Most popular
method, Annual Deprecn
=
𝑂𝑟𝑖𝑔𝑖𝑛𝑎𝑙 𝑐𝑜𝑠𝑡(𝐶)−𝑆𝑎𝑙𝑣𝑎𝑔𝑒 𝑣𝑎𝑙𝑢𝑒(𝑠)
𝑙𝑖𝑓𝑒 𝑜𝑓 𝑠𝑡𝑟𝑢𝑐𝑡𝑢𝑟𝑒(𝑦𝑟𝑠)
2. Constant percent Depreciation
method:=> p= 1 − (
𝑠
𝑐
)
1
𝑛 %
3. Sinking Fund Method=> Annual
deprecn
= S*Ic where, s= total sinking
fund
4. Depreciation from life of structure:
period(yrs) % deprecn
per year
Total
deprecn
0-5 nil nil
5-10 0.5 % 2.5%
10-20 0.75 % 7.5%
20-40 1% 20%
40-80 1.5% 60%
Total =90% and remaining 10% will be
scrap/salvage value

*Freehole Property=> nfnk"hf{ ePsf] ;Dklt nfO{
Free hole property
* Leased property:=> The property taken in
rent for some years for lease. Leaser can do
anything in it except selling and has to return
to the owner after leased period is over.
* Easement right=> Right to people regarding
placement of windows, older roads not to be
closed etc.
# Various methods of Valuation:
1. Cost based method => Value =
Original cost- Total depreciation+
value of land
2. Plinth area method=> Value =(Total
plinth/builtup area)*prevailing rate of
plinth per m2
– total depreciation +
value of land
3. Depreciation method=> Depreciated
value = P(1-rd/100)n
, where P= cost of
building at present market rate=
plinth area * prevailing market rate,
rd= fix rate of depreceiation, n= age of
property, i.e.
Life of structure(n) Value of rd
100 yrs 1
75 1.3
50 2
25 4
20 5
4. Rental method or Profit based
method=> value =capitalized value of
property = net rent * years
purchase(yp)
5. Capital value comparision method=>
value= compared value of similar
property in sorrouding
6. Development method=> Developers
do plotting in a large land leaving 40-
45 % of land for road/other facilities
and then sells by valuating the rate
#Specification:
 It is the written instruction
limiting and describing in
detail about the construction
works to be undertaken.
 It Describes: 1. Construction
to be done 2. The quality of
materials and workmanship,
3. Method of construction to
be adopted, 4. Tools and
plants used. 5. Methods of
testing, inspection etc
*Purposes of Estimation:
 It acts as legal document for the
contract document between owner
and contractor
 Guide to site
engineer/contractor/supervisor etc.
during construction
 Guide to the bidders/tenderers at a
time of bidding/tendering to quote
reasonable tender rate
 Guide to the manufacturing agencies
for their products
*TYPES OF SPECIFICATION:
1. General Specification=> It gives the
general idea of the whole works giving the
brief description of quality of materials,
workmanship etc. eg. B/W in soling with
handmade bricks, PCC(1:2:4), it is given by
designer, it is used for preparing cost
estimates , but it is not a part of
contract/legal document.
2. Detail Specification=> It gives the
detailed info regarding the quality of
materials and workmanship
Classes:
I) General proposition=> Are
general condition of contract and
are applicable to work as whole
eg. water supply for construction

# Importance of Specification:
 The cost of unit quantity of work
is governed by its specification
 Specification is an essential
contract document and is
required for court cases and
arbitration
 any changes in the specifications
of work, changes the tender rates
 In the event of conflict between
specifications of work and the
drawings, specification shall
govern
 Any Tender/Contract without
specification of work is
incomplete, baseless and govern
invalid etc.
