How to Accurately Calculate Concrete and Steel Quantities
Accurately estimating the amount of concrete and steel needed for a building project is an essential part of the construction process. Knowing how much material will be required ensures that there is enough to complete the project without having too much left over. In this blog post, we’ll discuss the various methods for calculating concrete and steel quantities for a building project so that you can create accurate estimates and complete your projects on time and on budget.
What is building estimation?
Building estimation is part engineers job when it comes to civil engineering. It involves calculating the exact amount of material such as steel, concrete, plaster, tiles, and paint that will be used for the construction of a project. Engineers must have a thorough knowledge of civil engineering principles in order to accurately estimate the quantity of material needed. Civil estimators need to know how many cubic feet of concrete are needed for a specific section of the structure, as well as how much steel or other material will be necessary. They must also consider the length of time the project will take in order to calculate the correct quantity of materials.
The importance of accuracy
Accuracy in estimation lead advantage in any given projects. It lead the any construction company to achive building project within budgets and time frames as planned. This is why civil estimations for quantity of materials such as steel, concrete, plaster, tile and painting need to be properly calculated by professionals. Civil estimators will take into account all factors associated with the cost of materials such as design, labour cost, transportation, shipping costs and much more before providing accurate estimates for these materials. Additionally, estimators will often use various calculation methods such as standard cubic foot rate, area or length measurement, weight measurements, labor based calculations and other methods depending on the scope of the project. Knowing how these different calculation methods can affect material quantities is an important part of civil estimations for an accurate estimate of costs for these materials. Furthermore, civil estimators also need to take into account factors such as storage costs and health & safety when calculating material quantities, as these can all affect the overall cost of a project.
Steps to take when estimating
while taking out the estimation and quantity from building project you must need accurate drawing in advance i.e bar bending schedule, architecture drawing, lift drawing, doors and window sizes, kitchen platform size, lobby area drawing, sliding windows drawing, plumbing and fire fighting drawing etc. These drawings are necessary for civil engineers to calculate concrete and steel quantities with the help of software like AutoCAD. Moreover, by analyzing all kinds of measurements like length, width, height, diameter of pipes, level changes, etc., concrete and steel can be estimated precisely. Additionally, one should also take note of areas which are more prone to weathering like outside walls or terraces so that the estimated quantity can be raised accordingly. Finally, one should ensure that there is sufficient allowance for wastage so that the estimated amount doesn’t exceed the actual requirement of concrete and steel. This step is very important as it will help keep a control on the expenses of the construction process.
What about larger projects?
In larger projects further detalis of garden, road, community halls, swiming pools, gymkhannas, tennis courts is mentioned while considering estimations . It requires a civil engineer or an experienced architect to do an accurate civil estimation. The quantity includes all the materials such as sand, gravel, stone aggregate, water tankers, trenches for piping etc. Apart from concrete, steel quantity will also include fabrication, welding activities, staircases, rails & ladders required for the project. Plaster quantities may include materials such as gypsum plasterboard, joint cement compound, water-resistant plasterboards etc., whereas tile quantity involves all types of tiles such as ceramic tiles, vitrified tiles and marbles. Last but not least, painting quantity involves primers, undercoats, top coats etc. All these quantities need to be accurately calculated in order for a project to be completed successfully.
