Estimating is the technique of calculating/computing the various quantities and the expected expenditure to be incurred on a particular work/ project. For all engineering works it is required to know beforehand the probable cost of construction known as the estimated cost. Necessary for preparing an estimate are drawings like plan, elevation and sections of important point’s, detailed specifications about workmanship & properties of materials, Standard schedule of rates of the current year. Estimate is required to invite the tenders and Quotations and to arrange contract, also required to control the expenditure during the execution of work. Construction projects require huge amounts of capital and have many risk factors due to the unique industry characteristics. For a project to be successful, accurate cost estimation during the design phase is very important. Estimate decides whether the proposed plan matches the funds available or not. In this project we estimate the quantities required for the construction of the Tailor shop and later calculate the cost by preparing the abstract of cost.

4. INTRODUCTION
 An estimate is a calculation of the quantities of various items of work, and the expenses
likely to be incurred there on.
 The total of these probable expenses to be incurred on the work is known as estimated
cost of the work. The estimated cost of a work is a close approximation of its actual cost.
 The agreement of the estimated cost with the actual cost will depend on accurate use of
estimating methods and correct visualization of the work, as it will be done. Importance
of correct estimating is obvious.
 It is therefore necessary to prepare the probable cost or estimate for the proposed work
from its plan and specification.

5. PURPOSE OF ESTIMATING
 To calculate the number of different categories of workers that is to be employed to complete the work within
the scheduled time of completion.
 To assess the requirements of tool, plants and equipment required to complete the work according to the
programmed.
 To invite tenders and prepare bills for payment.
 To fix up the completion period from the volume of works involved in the estimate.
 To draw up a construction schedule and programmed and also to arrange the funds required according to the
programming.
 To justify the investment from benefit cost ratio. (for ideal investment, this ratio should be more than one)

7. METHOD OF ESTIMATING
The quantities like earth work, foundation concrete, brickwork in plinth and super structure
etc., can be workout by any of following two methods
LONG WALL-SHORT
WALL METHOD
 In this method, the wall along the length
of room is considered to be long wall
while the wall perpendicular to long wall
is said to be short wall.
 To get the Measurement of Materials and
Works length of long wall or short wall,
calculate first the centre line lengths of
individual walls.
CENTRE LINE METHOD
 This method is suitable for walls of
similar cross sections. Here the total
centre line length is multiplied by breadth
and depth of respective item to get the
total quantity at a time.
 When cross walls or partitions or
verandah walls join with main all, the
centre line length gets reduced by half of
breadth for each junction

20. CONCLUSION
 All the measurement should be taken accurately so that there will be no chance of error in
estimate
 Estimate a probability given data, and calculate a probability when assumptions about the
symmetry of an object or situation can be made
 Appreciate that the method of maximum likelihood estimation is an important way of
estimating a parameter as we have taken Long wall Short wall method.
 Detail measurement and Calculation of quantities should be done of all the required data.
 With the help of further calculation the total cost of project it taken out i.e. 13,163.63
