Conclusion
The report deals with step by step working of a rectangular house consist of two rooms the bedroom and living room, first of all the take-off is calculated lets revise again what is take-off. “Quantity take-off is a process in which calculations of building material and labor needed to complete a project is made, the calculation is made by experienced professional during the preconstruction phase, these estimators has developed many techniques in order to enhance quality work, the most important part to carry all the construction process smoothly with the given time.The quantity take-off is off great importance because it helps to measure the cost of various equipment and cost of labor in correspondence to material quantity and time. After that the bill of quantity is prepared for each section the sub-structure section, super-structure section and finishes after that the bill of quantity of all the sections is added in order to get the provisional sum of the whole project. The bill of quantity is the most important part of a project phase under process because it helps us to plan the cost of the overall project include labor, material and equipment charges used in the project, it also help us to design a work flow for construction planning step by step and moreover it also help us to manage material scheduling including the overall material requirement including the waste.
