In this exclusive civil engineering article, you will be taught how to prepare the complete estimate of a building in excel with the help of the centerline method. The estimation is done based on the building or house plan. The building is a load-bearing structure i.e. the foundation is made of brick masonry.

The centerline method is simple and the calculation process is very fast. Under this method sum of the total length of center lines concerning all walls, long and short should be determined. After that, the centerline length is multiplied with the breadth and depth of the relevant item to obtain the total quantity at a time. For each junction, half the breadth of the relevant items or footings should be subtracted from the total center length.
