Centre Line Method to Estimate the Quantities of Building

 


The centre line method helps to estimate the building quantities more accurately, thus the right requirement for the building materials and associated costs has been obtained. In the centre line method, a centre line has been established, and the distance has been measured from it, which helps to obtain the actual quantities of the building components.

In the first step of the centre line method, the total centre line length of the walls has been estimated. In the next step, the depth and breadth of the building components have been multiplied by the total length of the centre line, thus obtaining the total quantity of the building components. The centre line length for the different sections of the building’s walls has been estimated separately.

In the case of the verandah walls or partition walls that joined to the main walls, the length of the centre line has been reduced by half of the breadth layer, which has been joined with the verandah walls or partition walls. The centre line method helps to complete the overall building quantity estimation more quickly. The centre line method can be used to estimate the material quantities of the rectangular, circular, hexagonal, octagonal or other types of building structures.

Procedure for Estimating the Centre Line Method

There are several steps that need to be followed for conducting the centre line method. These steps are as follows:

Determining the building layout

In the first step, the estimators should have a clear understanding of the layout of the building structure. In this regard, the estimators should have the knowledge about the beams, walls, columns and other building components that are going to be measured under the centre line method.

Identifying the centre line

After collecting the information about the building layout, the estimator should have to determine the centre line for each of the building components. In this context, the centre line for each building component should be darwin more accurately throughout the estimation procedure.

Measuring the length and areas

In the next step, the length of the beams, walls, columns and other building components has been measured along with the centre line. In the case of the columns and beams of the building structure, the length has been measured along the centre line and the cross-sectional dimensions. To obtain the areas of the building components, the estimator has to measure the width to the centre line, and it has to be multiplied by the length.
