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.
Breadth or depth of first step is 0.15 m. Depth of second step is 0.30 m. The third step is 0.30 m. Framework or Superstructure height is 3.20 m. To determine the magnitude for the structure via centre line method, Long walls dimension or length = 3.5 m + 3.5 m + 0.30 m + 0.30 m x 2 = 15.2 m.
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.
11 sie 2023 · 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.
This civil engineering article briefly explains the center line method for measuring building. Several cost estimation methods are available for working out the quantity of different items like earthwork, foundation, concrete & brickwork (plinth and superstructure).
After the calculation of these basic quantities, we can easily estimate the quantities for various items to be used like quantity of plaster, quantity of paint, quantity of damp proof course, etc, by using total centre line length and respective dimensions.
In this method, first, you find the center line of each and every wall in the building. Then you join up the length of those lines, which gives you the total wall length in the building in question. Finally, the total length is multiplied by the breadth and depth of the walls to get the total quantity estimate.
