If the weights are divided into practical bar diameters and shapes, this method give a reasonably accurate assessment. The factors, however, do assume a degree of standardization both of structural form and detailing. This method is likely to be the most flexible and relatively precise in practice, as it is based on reinforcement requirements indicated by the initial design calculations. Method-3 for Reinforcement Estimation: For this method sketches are made for the ‘typical’ cases of elements and then weighted. This method has the advantages that: (a) The sketches are representative of the actual structure (b) The sketches include the intended form of detailing and distribution of main and secondary reinforcement (c) An allowance of additional steel for variations and holes may be made by inspection. This method can also be used to calibrate or check the factors described in method 2 as it takes account of individual detailing methods. When preparing the reinforcement estimate, the following items should be considered: (a) Laps and starter bars A reasonable allowance for normal laps in both main and distribution bars and for starter bars has shall be considered. It should however be checked if special lapping arrangements are used. (b) Architectural features The drawings should be looked at and sufficient allowance made for the reinforcement required for such ‘non- structural’ features. (c) Contingency A contingency of between 10% and 15% should be added to cater for some changes and for possible omissions. 2

### 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.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• 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.
