This is needed to determine both the lengths of the rebar and how many rows and columns are needed. Subtract the clearance from the length and width to find the dimensions of the grid. For example, if the slab is 10′ x 10′ and the clearance is 3″, the size of the rebar grid will be 9′ 6″ x 9′ 6″.
Estimation of steel reinforcement quantity for concrete slab, footing and column, beams etc. is crucial for the cost evaluation for the construction. Design drawings are used as a base for computing rebar quantity in different structural elements. This article presents steel quantity computation process for slabs, columns, and footings.
connections is then backed into the weight of the total steel as a percentage or to the GFA as a square foot cost. SECTION 2: TYPES AND METHODS OF MEASUREMENT: Quantifying structural beam and column connections involve measuring the components in SF(square feet), LBS(pounds) or TONS. Welds and cuts are measured in LF(linear feet).
Jul 09, 2018· Multiply the obtained area by the number of columns in the storage warehouse. There are eight concrete posts so multiply it by 8. Total Area = Area ( Number of columns ) Total Area = 3.00 ( 8 ) Total Area = 24 square meters. 4. Solve for the area of the plywood you will use. In this case, the required size of plywood is 4' x 8'.
how can be possible that 1 sq mtr slab area required 25 to 30 kg steel in simple term residential building in slab having a thickness 110 to 125 mm provided Reinforcement generally #[email protected] c/c for distributer bar & #[email protected] c/c spacing then calculation says that 5.530+1.825 => 7.355 Kg Per Sq mtr in slab
Use our concrete calculator to determine the amount of concrete needed to pour your concrete slab. Enter the width and length of your slab in metres. Then enter the thickness of your slab in millimetres. The amount of concrete you require will display in cubic metres in the blue box.
Jan 24, 2017· The approximate Steel consumption per sq.ft built up area (BUA) is 4 kg per sqft (for low rise construction i.e., less than 4 floors of construction). Steel contributes the most among all individual materials, about 25% of total material cost.
3. Calculating The Weight Of Steel Bars. Weight of steel bars = Length of bars × unit weight. 20 mmØ bar = 115.5× 0.75 =73.12 kilogram. 25 mmØ bar = 70 × 1.17 =81.90 kilogram. 10 mm bar = 336' × 0.19 =63.84 kilogram. How To Calculate The Steel Quantity For Beam From Drawing
Next, figure the amount of cubic feet in the wall and floors. Multiply the total square feet times the thickness of the floors and walls. For example, if your walls are 300 feet square and 8 inches thick ( 8 inches converted to feet is .75), multiply 300 times .75, and you have the total cubic feet of concrete .
Allsteel carries screws in 2 different lengths: 1½ inch and 2 inch. The 1½ inch variety is the best all-purpose size. The table below can be used to figure approximate quantities of screws for various purlin spacings and sizes of roofs. Screws are available in quantities of .
GROUND FLOOR PLAN Total Builtup area = 196.72 Sq. M (2128.75 Sq. Ft.) Carpet area for EEIC = 78.96 Sq.M. (850 Sq.Ft.)

Calculate the number of blocks required by substituting the area to be built and the size of the block in this equation: total area of walls / area of a block = number of blocks required. To conclude the example, building 2,100 square feet of wall from 0.89-square-foot blocks requires 2,360 blocks — 2,100 x .
Jun 26, 2018· To calculate the quantity of cement, sand, and aggregates required for a flat slab first we need to calculate the volume. Area of flat slab = 1000 sq.ft =93 sq. m. The minimum thickness provided for slab is 150mm .(
So, for the plan area of 800 Sq. m. the area the total volume of concrete required = 800 x 0.038m3 = 30.4m3. Thumb rule for Steel quantity required for Slab, Beams, Footings & Columns: Steel required in residential buildings = 4.5 Kgs – 4.75 Kgs / Sq. Ft. Steel required For Commercial buildings = 5.0 Kgs-5.50 Kgs/Sq. Ft.
While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters. Concrete can be purchased in multiple forms, including in 60 or 80-pound bags, or delivered in large amounts by specialized concrete mixer trucks.
Concrete rebar calculator plan view diagram Round Measurements To 1/32" 1/16" 1/8" 1/4" 1/2" Running Bar Points (Length - Left to Right):
We must remember than steel is ductile in nature and is subject to elongation. Hence, the length of a bar is increased when bends or hooks are introduced. Hence, certain deductions are needed to offset this increase in length. Cutting Length = True Length of a bar – Deductions. For 45 degree
Jan 21, 2019· Know how much does it cost to build a duplex house in 30 x 40 site. And also learn how many bags of cement, tmt steel, bricks/ blocks and jelly stones is required to build to home in 1200 square feet.
Aug 04, 2017· Following are the steps to calculate the quantity of steel for RCC slab 1. Prepare a bar bending schedule in order to classify different shapes of bars (bent up bar, straight anchor bar, eos bar, curtail bar etc) and diameters. 2. List down all the shapes .
Concrete blocks are concrete masonry units, or CMUs, but we often refer to them as concrete blocks or cinder blocks Learn more about concrete masonry units.A wall typically requires 1 1 / 8 blocks per square foot.. Finding how many concrete blocks you need for your project can seem like a confusing and challenging task, but it can be simplified using the calculator above.
