If we need concrete of 5 cubic meters, the required formwork can be found with the rule of thumb by multiplying the amount of concrete by 6. Remember that rules of thumb never give an exact amount, but you can use them for the approximate amount. This is very valuable knowledge for those who have already entered the civil department and will go on to learn these basics. A partial question of myself is that I did not receive the information from the propeller calculation in the formwork. Please post it. We shared a long list of rules of thumb used in construction for various activities. If you benefit from it, share it. As a rule, the units of measurement are different when compared to obtain the solution. Therefore, never consider units while using the rule of thumb. Rules of thumb play a crucial role when it comes to making quick decisions on the ground. Rules of thumb allow you to calculate the solution using a simple mathematical formula and make intelligent decisions when needed. Keep in mind that rules of thumb never give the exact results, but you can use them for rough results. There are many rules of thumb that we apply in construction.

Here I discuss the most commonly used thumb rules on the spot. Thank you for providing detailed information on civilian work. Now I can easily estimate my construction work. To save money in building construction, you need to follow certain guidelines and rules of thumb. Following these rules of thumb for building construction leads to money saving and economical construction. To calculate the weight of steel or reinforcement per unit length, the following rules of thumb can be used. Very nice, sir, you are amazing and your advice is very useful for everyone who works in civil engineering. The rule of thumb for construction cost estimates can speed up the rough estimation process. Based on rules of thumb in civil engineering, one can also have approximate costs and material and labor requirements. The thumb rule method is an approximate and comparative method.

As a rule and the units are not the same when we compare to get the results. So ignore the units when running the rule of thumb. But while you are using these rules of thumb, you need to remember that the rule of thumb never gives the exact or precise results, you have only used them for approximate results. Below are some important rules of thumb for calculating steel for slabs, beams, columns, and foundations. Do you have any rules of thumb for yourself? If so, let us know in the comments section, we would also like to learn something from you. Rules of thumb refer to an easy-to-learn process or standard based on practical experience rather than theory. It is not intended to be strictly accurate or reliable for every situation. Rules of thumb give us quick decisions on the construction site. It provides the rules of the mathematical formula and general ideas whenever necessary.

As engineers, we need to be practical and fast in the field of design. Basically, the basic rule is the guide for civil engineers to predictable results. This can vary up to a few percent, but there will also be a general idea. If we compare to get the result, the units in the rules of thumb are not the same. Therefore, never consider units when executing the rule of thumb. There are several rules of thumb that we apply in construction. Here I discuss the most commonly used thumb rules on the website. The rule of thumb can be called a guideline, idea, or principle that allows you to make quick decisions. „Arrive early” is a good and effective rule of thumb for most appointments. He was referring to manufacturers who often use their thumb to estimate measurements. This is a useful rule, even if it is inaccurate. The basic rules for building material requirements and construction work per unit area are given below: The Civil Engineering Rule of Thumb or the Construction Rule of Thumb will help you find the solution using a simple mathematical formula and make smart decisions as needed.

The site engineer and supervisor benefit greatly from the rules of thumb to make a quick decision. But we say about 600 no. This is called the rule of thumb. Because we can`t estimate every time based on individual needs. The above rule of thumb for steel in the JRC estimate is not as precise. For an approximate amount of steel required, see B N Datta, as shown below. The proportion of steel in concrete according to the IS code for various elements is indicated below: Suppose that for formwork we need to know the productivity of the formwork carpenter per day. From the above working rule of thumb, we use the rules of thumb for almost all calculations such as concrete calculation, personnel estimation, material requirements for plastering, waste calculation, masonry calculation, etc., The amount of cement needed for laying flooring can be calculated on the basis of the rule of thumb given below. Can you please give me an estimate of the thumb rule for multi-storey aluminum and glass façade buildings? Below are rules of thumb for civil engineering for masonry and cement quantity calculations.

For plaster, the amount of material varies depending on the different mixing ratios such as concrete and the rule of thumb for working with plaster listed below. As a general rule, any IS CODE such as IS1200 for measurement. Below are rules of thumb for reinforcement in concrete elements, rules of thumb for civil engineering are essential for any civil engineer, civil engineer or construction manager. They play a crucial role in making quick decisions on the ground. There is basic structural knowledge that every civil engineer needs to know. Thanks to its very good explanation of how to calculate all the details in the rules of thumb subject very inforamtive. How can I download its details next to the screenshot to use? 1) Slab – 0.8-1% of the total volume of concrete (ceiling steel calculation thumb rule) Every civil engineer or construction manager must have basic knowledge of some basics of structural engineering. Those listed below must have civil engineering knowledge and practical knowledge. These will cover an in-depth knowledge of the field and practice of civil engineering. This article contains tips and tricks for civil engineering that will be of immense importance to civil engineers. Rules of thumb help you calculate the amount using a simple mathematical formula and make smart decisions when needed. The method for determining the width-depth ratio of reinforced concrete beams is not specifically specified in the codes.

However, a rule of thumb can be used, that is, a depth two and a half to three times wider than the beam. For long beams, it is usually economical to use deep and narrow sections. We apply a lot of rules of thumb in construction, and here I share some thumb rules that are most commonly used on site. An important rule of thumb for the calculation of steel according to the type of building and for structural elements such as the slab, beam, column and foundation is very useful. 1) Slab – 1% of total concrete volume (slab steel calculation rule of thumb)2) Beams – 2% of total concrete volume3) Column – 2.5% of total concrete volume4) Foundations – 0.8% of total concrete volume Sometimes we need to move quickly to move forward. Each professional has kept his own rules of thumb. Rules of thumb play a critical role for civil engineers/site managers in making quick on-site decisions. There are a number of rules of thumb for civil engineers that we have used in construction work. Below are some of the most commonly used rules of thumb on the construction site.

The rules of labor productivity art are useful for calculating the total labor needed for your next schedule. Based on experience and practice, the following rule of thumb is used for plaster in the construction and construction of buildings. First, we need to understand the importance of the rule of thumb before we get into the discussion. Below are some important rules of thumb for calculating the amount of steel for different buildings. You can also use BN Datta recommendations for a more accurate result. The minimum percentage of steel in slabs is 0.8% and the maximum percentage of steel in slabs is 4%. 1 liter of formwork oil is consumed per 15m2 of formwork. Estimation of construction work – Short wall to long wall method, center line method, formwork oil is applied to the surface of the formwork slab used to facilitate deburring or dismantling of concrete. The total volume of concrete for a given slab = 5 x 4 x 0.15 For an accurate calculation, see Design of the concrete mixture for different types of concrete The volume of concrete required for the area per square foot = 0.038 m3 / square foot of flat area. Thus, 10000 bricks are needed for a masonry of 20m3.

Steel required = 2.25 X 1%. (1% of the table from the top) Sir, square meters of surface and cubic meters of concrete. Can we assess that? The units are out of sync For 100m2 of formwork oil needed for formwork = 0.065 X 100 = 6.5 liters, I lean for more impermation on this site. All the comments are very correct and easy to learn. For more accurate results, you can also use the recommendations of BN Datta: – Suppose that the formwork layer has a length, width and depth of 2.44 x 1.22 x 0.012 The components of the formwork are formwork layers, slats and nails. Required steel weight = 0.0225 X 7850 = 176.625 kg According to B N Datta, the amount of steel used in different parts of the building can be easily calculated with the following recommendations. For a surface of 800m² 0.38cum concIe 800 x 0.38 = 304cum concrete. Steel requirements in residential buildings = 4.5 kg – 4.75 kg/square foot. In have 2plots. 23*29.

Second 25*36. TOTAL LENGTH 48. IF I TAKE SQURE 48 * 29. PLS HELPS ME WITH PLAN G+2. EARTH. FLOOR FOR OWNERS 1 AND 2 FLOOR FOR RENT. Read more: Construction Calculator (Civil Engineer Calculator) Steel costs are very expensive compared to other building materials and excessive steel purchase affects the project budget. A good designer limits the use of steel. The concrete volume of 0.038 m3 of concrete is used for each square foot of flat surface, the cost of formwork is almost 15% to 18% of the total cost of construction.
