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 the respective items to get the total quantity at a time.
Example 1 Calculate the circumference of a circle with radius 8 cm. Solution Using the formula, Cr=2π, gives C =28××π=50 26548246m . c =50.3 cm (to 3 significant figures) Example 2 The diagram shows a semicircle of diameter 12 cm. Calculate the perimeter of the semicircle. Solution Length of curve =π×÷12 2 =18.84955592 cm Straight edge ...
Part II covers some specific calculations and their formulas and has examples of how to do such calculations. The Appendix contains a set of charts, graphs, and other helpful tables

Centre Line Method of Estimation. There’re two rooms. Determine concrete in base (foundation), brickwork in base (foundation), and earthwork in excavation. Every room dimension is 3.5 m and 4 m. The second room is same like the initial room. Complete wall is 0.30 m.
Estimate of Building Work By Centre Line Method. By multiplying the total centre line length with width and depth or height, we can calculate the quantities of different work items. But when we do this, we take the certain part double and leave an equal part, but it doesn’t affect the quantity.
The center line method involves using a reference line, known as the center line, to measure distances and calculate quantities of various building components. This method is particularly useful for linear structures such as walls, beams, columns, and pipes.
