Wall finishing Inside wall 12 mm Cement plastered and white wash 3 coats. Method 2-Centre line method. In this method the external lengths of walls are calculated. Walls running in longitudinal direction are generally long walls and walls running in the transverse direction are short walls. Long walls and short walls are separately considered pf estimation. First find out the Centre to Centre length of long walls and short walls from the plan. Find out the length of long wall by dw focus wordpress pdf Centre to Centre length centre line method of estimation pdf one breadth of the wall. The wall which is taken first is to be treated as long wall though its.

Center Line Method Of Estimation: There are three different methods of estimation. Center line method. Long and short wall method. Crossing method. In this article, I will discuss center line method briefly for the estimation of materials. What Is Center Line Method: In this method of estimation, the total center line length of walls in [ ]. Methods of Estimation for Building Works. The estimation of building quantities like earth work, foundation concrete, brickwork in plinth and superstructure etc. can be worked out long wall short wall method and centerline method. This method is simple and accurate and there is no chance of any mistake. This method may be named as long wall and short wall method, or general method. Centre line method In this method known as centre line method. This method is easy and quick in calculations. In this method sum total length of centre lines of all walls. Centre to centre line method is one of the methods for preparing an estimate. In this method first, calculate the centre line length of the wall, and then multiply it with the .ESTIMATING AND COSTING. METHOD II. Centre Line Method. In this method known as centre line method sum-total lengt lines of walls, long and short, has to . Estimation is predictive process and is used for finding quantity & cost of required for completing projects. Here we discuss centre to centre line method. In this method of estimation, the total center line length of walls in a Quantity of wall plaster for 2 sides = Total centre line length x Height of. Centre line method. Long wall and short wall method. In this method measure or find out the external lengths of walls running in the direction generally the.

The quantities of various items such as earthwork in excavation , foundation concrete , brickwork in foundation and plinth, brickwork in the superstructure, etc. In this method of estimation, the total center line length of walls in a building is first calculated, then the center line length is multiplied with the breadth and depth of respective item to get the total quantity at a time. Fir different sections of walls in a building, the center-line length for each type shall be worked out separately. In the case of verandah walls or partition joining with the main wall, the center-line length shall be reduced by half of the breadth of the layer of the main wall that joins with the partition or verandah wall at the same level. A number of such pints arc simnel first to calculate the center-line length. By this method, estimates may be prepared more quickly, and this method is as accurate as of the other methods. Only in the case of an unsymmetrical wall, which is generally rare, no advantage may be claimed by this method over others as the center-line length varies at every layer. But to estimate circular, hexagonal, octagonal, etc. In this method the longer walls in a building generally in one direction are considered as long walls and measured from out to out: and the shorter or partition walls, in a perpendicular direction of the long walls, are considered as short walls and arc measured from in-to-in for a particular layer of work. These lengths of long and short walls arc multiplied separately by the breadth and height of the corresponding layer and are added to get the quantity.
