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.
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.
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.
To quickly determine the total quantity, the total centre line length is multiplied with breadth and depth of related item. When cross walls or partitions or verandah walls are affixed with main wall, the length of the centre line is reduced by half of breadth for each junction.
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.
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).
