Short wall length for item = length of centre line of short wall – width of item. Advantage: 1) This method is simple abs accurate. 2) There are no chance of mistakes in calculate. 3) The method gives quantity quickly.
2) Centre line method: - As the name itself implied, the total centre line length of wall of same have similar foundation is worked from plan of structure and is then multiple by respective dimension to obtain required quantity of structures. Total length of centre line remains same for sub structure and superstructure item except in cases where are cross wall like at junction of wall. This method is simple and easy in calculate for same structure having no cross wall. If there are crossed wall, then special care is to taken in taking out dimension at all such junction point. The simple rule is to deduct half width of respective item for each junction point from total length of centre line. In case of building have different types of wall each set wall is considered separate i. e 1st determine total length of centre line of each type and make deduction for each junction as state above and multiple by respective width and depth that item to find out its quantity. This method have length will remain same for excavation in foundation, for concrete in foundation for all footings and for superstructure. This method is quick and easy but required special attention and considered at junction meetings point of partition or cross wall, etc. Procedure: - Prepare the foundation plan of given drawing, write centre line length of each wall. Find the total length of centre line of long and short wall, having same type of footing.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
