1. Know the actual dimensions of the footing as to its length and width. 2. Remember that the minimum underground protective covering of concrete to the steel reinforcement is 7.5 cm. 3. If the plan does not specify hook or bend of the footing reinforcement, the length of the bar is equal to the length or width of the footing minus the 7.5 cm protective covering at both ends. 4. If the plan indicate hook or bend of the reinforcement, the bar cut should include the allowances for the hook and bend. 5. know the spacing distance of the steel bars both ways to determine the exact number required. As much as possible, select the appropriate commercial length of steel bar which is divisible by the required cut length to avoid unwanted extra cut. Various problems in computing steel bar reinforcement will be encountered because of varied measurements and designs. Problems however, usually arises on reinforcing members which requires cutting and bending such as lateral ties, stirrups and the like. Others could be determined by direct counting such as straight bars for columns, beams, girders and floor slab reinforcements.
