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.
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. Short walls dimension or length = 3 x 4.30 m = 12.90 m. Wall complete dimension or length = 12.90 m + 15.2 m = 28.1 m
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.
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.
You have to calculate the walls’ total centre line length of the same type, long and short, using similar foundations and footings. Now multiply this centerline length by width and height to calculate the quantities of the various work item.
Centre line method is adopted for walls of similar cross sections. In centre line method, total centre line length of all the walls is first measured, provided walls are of same type, long and short having same cross section and same type of footings.
How to Calculate Estimate using Center Line Method. We have a plan of three rooms. Center to center length and breadth are required and utilized when calculating estimate of a room. In the plan, length = 5 m and breadth = 4.5 m. Also, three rooms are of same dimension. Thickness of wall = 0.3 m.
