    Gray water: It is water that comes from the kitchen sinks, bathrooms, bathing water, water from washing clothes, utensils, or any other wastewater which does not contain feces of humans or other animals.

    Blackwater: It is now apparent that it is water which contains feces of animals and humans, it is water from urinals, toilet seats, commodes, etc. is called black water

    And to tell the difference in the sewer is hard because it generally mixes in the sewer, if not provided with different outlets.

    I hope this helps!

    You can measure the density of soil with the help of different test as mentioned in IS code. After getting density you can use the formula: Density = Mass/Volume You know density and volume, you will get Mass out of it

    There are certain methods to remove the delaminated concrete, and then formwork is to be fixe. After that, the application of repair material like a dry pack, and wet pack, shotcrete, is carried out if reinforcement is not removed while fixing the pipe.

    You can try one other method also, by fixing plate bonding in the beam on the bottom to enhance the flexural strength, you will have to rest the plate on the bricks, and for that, you will have to remove the top layer of the brick. You also may need to provide scaffolding if you are altering the load-bearing wall. As it is a load-bearing structure, if any alteration is done in the load-bearing wall, it should be done with the consultation of a structural engineer.

    Time Estimation: Actually there are many Softwares out there in the market but the most commonly used in the Indian market are Primavera and MS project for Scheduling and estimation of time required, but the software is not limited to this two, there are many like TILOS which is used widely in Europe, it is more useful for estimation of linear projects like metro and roads.

    Quantity: In most of the companies the quantity estimation is done in Excel, but there is much other software for quantity estimation, the most common are Revit and Tekla, from which you can directly model your project and take off quantities.

    Material and cost needed for 10 Cu.m of concrete are mentioned below:

    Cement Sand Aggregate 20mm
    1 2 4 Ratio of cement
    Total 7 =1+2+4
    For 10 cu.m
    Considering wastage in concrete(7%) 10.7
    Shrinkage factor 1.52
    Dry concrete 16.264 =10.7*1.52
    Description Cement Sand Aggregate
    Calculation =(1/7)*10.7 =(2/7)*10.7 =(4/7)*10.7
    Cu.m quantity needed 1.53 3.06 6.11
    Wastage 2% considered 10% considered 5% considered
    Total Cu.m Needed 1.56 3.37 6.42
    Bags = 1.56/0.0345
    Total Quantity 45.21 Bags 3.37 cu.m sand 6.42 cu.m aggregate

     

    • Now multiply with the rates of the material
    • Add the rate of a skilled and unskilled worker
    • Water and electricity may be considered:: 2% x (Total cost of the worker + Total cost of material)
    • TEP cost may be considered 1% x (Total cost of the worker + Total cost of materials) and also add the owning and operating cost of required machinery
    • Profit and overhead cost will be as per decided

    The total cost will be addition of above all for 10 Cu.m
