What is Centre line method in construction?

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. After the calculation of centre line length, it is multiplied with the breadth and depth correspondingly to find the total quantity.

What is meant by Centre line?

noun. any line that bisects a plane figure: the centerline of a building plan. a line along the center of a road or highway dividing it into separate sections for traffic moving in opposite directions. Radio. the perpendicular bisector of the line connecting two radio transmitters.

How do you work out the center line?

The centre line is half way between the external girth and the internal girth.

What is Centre to Centre in construction?

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 breadth and depth of the wall to find out quantity.

What is the difference between Centre line method and long or short wall method?

In long wall and short wall method the walls are taken separately, while in the centre line method, the centre line lengths of all the walls are combined.

What is center to center?

The Center-to-Center of any drawer pull is the distance between the center of one screw hole to the center of the other. Measuring the center-to-center of the drawer pull is key in determining what new hardware will fit and whether you’ll need to drill new mounting holes or fit into existing ones.

What is difference between center line method and separate wall method?

For which kind of building the Centre line method is specially adopted for estimating?

3. The ‘centre line method’ is specially adopted for estimating? Explanation: By center-line method, estimate for earthwork, concrete work or brick work for all walls of the building can be done at a time.

What are the two methods of building estimate?

Following are the three different methods used for estimating building works:

• Long wall – short wall method.
• Centreline method.
• Partly centre line and short wall method.

How do you find the center line of a building?

What is center line method of estimation?

What Is Center Line Method: 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.

How do you calculate the length of a circular building?

This method is as accurate as other methods (except unsymmetrical wall). This method is suitably used for estimating circular, rectangular, hexagonal, octagonal etc shaped building. First we need to calculate total center line length of the building. Total center line length = 2 x 5.3 + 2 x 4.3 = 19.2 m.

How to calculate the center line length of a verandah wall?

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.
