Rate Analysis of M25 Concrete Manual Mix and (Ready Mix Concerte) RMC

M25 Concrete Analysis.

Hello All, 

As we are seen in last few blogs of Rate analysis we are giving detailed Description of Rate analysis, as well as we are providing the Excel file Along with this blog.

In this blog we are going to See the analysis of Most usable concrete Grade.

Why most Usable?

M25 Grade is a Middle grafe whuch is commonly use in building or any other construction industry.

Industry's uses of M25.

1. Residential : Most of structural designer s are preferring M25 concrete. because it can be used at any level like Footing, Column, Beam, Staircase and mostly in Slab.

M25 Concrete required more than other grade concrete in any residential project. 

2. Commercials : Most of Slab can be cast in M25 Grade  Concrete.

3. Infrastructure : Most of Conctere Roads are Done by M25 Concrete. If you are searching goverment tenders you can observe that most of time Lots of tenders are included M25 concrete.

4. Industrial : Many Industrial building is Using Trimix work insted of normal flooring because of heavy movement. In this type of building designers are preferred M25 Concrete.

As well as we can say this Universal Grade of Concrete.

M25 can be fit at every stage.Like.

1. Column

2. Beam

3. Slab

4. Staircase

5. Trimix

6. Road.

8. Retaining Wall

9. Raft.

10 Footing.

11. Trenches

12. Drains

13. RCC Wall

14. Non structural Wall

15. Cover Blocks (It need 1 grade higher than actual concrete, but lot of users are using M25 grade.)

16. Infra Work, Etc.

Requirement of Material for M25 Grade Concrete.

1. Cement OPC (43/53 Grade Cement)

2. Crush Sand / River Sand

3. 10mm Coarse Aggregate/ Metal

4. 20mm Coarse Aggregate/Metal

5. Admixture

6. Water

7.Fly Ash (As per Requirements)

As shown in picture we are making the analysis of M25 Concrete.

This Analysis is prepared for 1 Cum Concrete Quantity.

Before analysis we need to see the market rate of Above mentioned material as we had considered following rates here, those rates are as belows.

Cement : ₹235 + 18/% GST Per Bag

Crush Sand : ₹3000.00 + 5% GST Per Brass

10mm Metal : ₹2500.00 + 5% GST Per Brass

20mm Metal : ₹2500.00 + 5% GST Per Brass

Admixture : ₹32 +18% GST Per Litre

Water : ₹ 0.08 + 18% GST Per Litre.

Above rates are can be varies as per geographically locations and Specifications.

If you need to calculate more Quantity You can download excel sheet.

Material required for 1 Cum

1. Cement : 6.90 Bag/Cum 

2. Crush Sand : 0.324 Brass/Cum

3. 10mm Metal : 0.154 Brass/Cum

4. 20mm Metal : 0.251 Brass/Cum

5. Admixture : 2.070 Brass/Cum

6. Water : 162 Liter Brass/Cum

Here we need to Consider some wastage percentage like Handling Wastage and Wastage during work.

1. Cement : 3%

2. Crush Sand : 7%

3. 10mm Metal : 7%

4. 20mm Metal : 7%

5. Admixture : 5%

6. Water : 5%

If we get all above data now we can be make Rate analysis

 

Rate Analysis for M25 Grade Concrete - Manual Mix

Material

1. Cement : 7.10 X ₹235 = ₹1670.15

2. Crush Sand : 0.3464 X ₹3000 = ₹1039.29

3. 10mm Metal : 0.1647 X ₹3000 = ₹411.82

4.20mm Metal : 0.2688 X ₹3000 = ₹671.97

5.Admixture : 2.1735 X ₹32 = ₹69.55

6. Water : 170.10X ₹ 0.08 = ₹13.61

Material Total Amount : ₹ 3876.38

Labour

M25 Concreting Labour  : ₹ 450 / Per Cubic Meter 

(For Quantity More than 40 Cum)

Total Amount ( Material + Labour ) = ₹4326.38 + Taxes.

But here you can be add Overhead cost of following 

1.Plant and Machinery, 

2. Water

3. Electricity

4.Other overheads

and Contractors profits.

Same thing we can be done for M 25 Ready mix concrte but here we are only consider in material cost as following

M25 Ready Mix Concrete : 1.00 Cubic Meter + 2% Wastage

Rate :  ₹3728.82 + 18% GST

Material Amount : ₹3803.40

(Concrete Pump will be provided free of cost if quantity is more than 40 Cum)

Labour : ₹350/ Cubic Meter (For quantity more than 40 Cum)

Total Amount of M25 Ready Mix Concrete for 1 Cubic Meter : ₹4153.40 + Taxes

External Painting Work - Standard Operating Procedures

Introduction:

This standard operating procedure enumerates the scope of Painting work to be executed in Tower area as specified in the approved drawings and at places when instructed by the Tower-in-charge.

Responsibility:  

The respective Tower-in-charge is responsible to execute the work as per procedure.

Safety & protection:

Use scaffolding always and ensure the scaffolding is adequately braced with the permanent structure, for working at heights. Unless it is tagged as safe for use by Safety Officer no work should be carried out on that scaffold area.

PPEs like safety belts at height, helmets, safety goggles etc. should be used properly. 

Ensure the working area is kept clean for easy access.

Proper illumination to be provided during the work, if required.

Educate the workmen through pep-talk meeting. 

External Painting with Texture:

Preparatory works:

 Do staging for external works as per approved specifications.  

 Ensure all touch ups on external faces are done, if any such as repairs at jambs, any bad patch on wall and cutouts etc. Do cure the repaired portion.

 Ensure that surface to be painted is free from any dust, loose paint or grease.

 If any growth of fungus, algae or moss observed, need to be removed thoroughly by vigorous wire brushing and cleaning with water.

 Open all cracks which are present on wall surface.

 Moisten the wall surface, make paste of Dr. Fixit CRACK-X paste and water in proportion of 1:1 and fill it in crack with spatula or putty knife firmly by pressing in.

 Allow it to set for 24 hours.

 Make all surface wet to ensure proper bonding and ease in finishing.

 Do protect other external finishes prior starting painting application.

Texture Application:

 Check for the type of texture received is as per approved specification.

 For External faces of Tower use 2mm texture and for Internal faces such as lobby and light-well ducts use 1mm texture.

 Use of safety belts for working at height is must, ensure all workmen use it.

 Add water in texture as prescribed by manufacturer (3 to 5%) to achieve required consistency.

For Scratch Finish: 

Apply the texture on wall uniformly with the help of trowel in horizontal or vertical fashion whichever is easier.

 Within 5 minutes of application re-trowel the surface vertically down to achieve the desired finish of texture.

 Allow it to dry for minimum 16 hours prior application of paint.

 After completion of texture, do check for its design pattern, consistency as per specification.

 Do check application of texture is done on wall surface correctly and no patches are remained.

 Ensure all fallen material is cleaned.

For Bubble Finish: 

Apply the texture on wall uniformly with the help spraying machine.

 After Application achieve desired finish by pressing with moist trowel on applied texture.

 Allow it to dry for minimum 16 hours prior application of paint.

 After completion of texture, do check for its design pattern, consistency as per specification.

 Do check application of texture is done on wall surface correctly and no patches are remained.

 Ensure all fallen material is cleaned.

1st and 2nd Coat of Paint:

 Check the paint received at site is as per specification and approved drawing.

 Add the clear water in paint as specified by manufacturer.

 Apply the paint on wall using roller brush.

 At corners apply paint with painting brush.

 Ensure the two paints which met at corner do not overlap each other and finished in straight line.

 After completion of first coat do check the painted surface for consistent tone.

 2nd coat shall be applied only after getting instruction from Tower-in-charge.
