About :
The concrete consumption of the footing is a calculation that must be estimated to determine how many cubic meters will be needed to concrete the foundation. In addition, in the video I teach how to calculate the quantity of lean concrete, formwork and average steel consumption. ????

Hello, how are you? In today's video lesson, the focus will be on the foundation design of an isolated footing, where the foundation design was interpreted and after reading it, the quantities of materials for execution were calculated. The first point was about lean concrete, which simply requires calculating the volume based on the dimensions. Therefore, the main function of lean concrete will be to separate the concrete of the footing from the soil, thus avoiding contamination and pathological manifestations. A second point was the step-by-step calculation of the forms. The forms will be made of wood, but only on the column collar and on the base of the footing. A tip and trick is to consider all the faces, normally on the 4 faces of the element. However, the calculation of concrete consumption can be divided into 3 stages, where: column, truncated pyramid and base of the footing. These are simple formulas used, but they require a minimum knowledge of geometry, for example, the truncated pyramid formula that involves areas. In the end, the calculation for the average steel consumption was based on the tactic of several designers, which is to adopt an average value of 50 kg/m³ of steel. Simply take the concrete consumption and multiply it by 50. This will give us an average for the steel, but for perfect optimization of the foundation project, it is necessary to check the dimensioning. Therefore, knowledge about the quantity of the isolated footing favors greater accuracy in the budget of the work and control of expenses. This makes it easier to execute and purchase materials. However, it is always a good idea to use an additional factor of 10% at the end of the calculations, to estimate a reserve in case of a lack of material. Happy studying and watch the video indicated in the final card on how to calculate the size of the isolated footing. A BIG hug! Eng° Pedro Rodrigues
